Beschreibung
The TC2104.55JD.010 is a 110 mm bore tractor hydraulic lift cylinder with a 45 mm rod, 180 mm stroke, and 535 mm mounting distance. It sits near the top of the 535 mm mounting platform group — second largest bore in the range, behind only the 120 mm FS2604.55D4.010a. The 45 mm rod is the heaviest in the 535 mm group among the 110 mm and below bore cylinders, giving this cylinder a notably robust rod specification relative to its bore.
One geometry detail distinguishes this cylinder and the FS2604 from the rest of the 535 mm group: the stroke is 180 mm, not 200 mm. Three cylinders in the group — FT800, TF1004, and TF1204/TF1304 — use 200 mm stroke. The TC2104.55JD.010 and FS2604 use 180 mm. Same mounting distance, shorter stroke. That 20 mm difference is enough to make these cylinders non-interchangeable with the 200 mm stroke models, and the stroke measurement is what confirms which subgroup a given cylinder belongs to.
Ever-Power supplies the TC2104.55JD.010 as an aftermarket replacement for agricultural tractor hydraulic lift applications. The “JD” designation in the model number is treated here as a model code component only — no specific OEM fitment claim is made without confirmed documentation.

180 mm Stroke: What Separates This Cylinder From the 200 mm Subgroup
Within the 535 mm mounting group, stroke measurement is the first filter after mounting distance is confirmed. Three cylinders use 200 mm stroke; two — the TC2104.55JD.010 and the FS2604.55D4.010a — use 180 mm. That 20 mm difference is the dimension that routes a buyer to the correct subgroup before bore measurement resolves the specific model.
| Model | Bore | Rod | Stroke | Extended | Force @ 160 bar |
|---|---|---|---|---|---|
| FT800.55A.012 | 80 mm | 32 mm | 200 mm | 735 mm | ~80.4 kN |
| TF1004.55.8 | 90 mm | 35 mm | 200 mm | 735 mm | ~101.8 kN |
| TF1204 / TF1304 | 100 mm | 40 mm | 200 mm | 735 mm | ~125.7 kN |
| TC2104.55JD.010 | 110 mm | 45 mm | 180 mm | 715 mm | ~152.1 kN |
| FS2604.55D4.010a | 120 mm | 60 mm | 180 mm | 715 mm | ~181.4 kN |
Both the TC2104.55JD.010 and the FS2604.55D4.010a have an extended pin-center distance of 715 mm — 20 mm shorter than the 735 mm of the 200 mm stroke cylinders. A machine designed for 180 mm of stroke has its lift linkage geometry, maximum implement height, and mechanical travel limits all calibrated to that range. Fitting a 200 mm stroke cylinder from the same 535 mm mounting platform would extend the lift arm 20 mm past its designed endpoint — into mechanical over-travel — every time the lift is operated to full height.
Why large-bore cylinders may use shorter stroke:
As bore increases, the cylinder generates substantially more force at any given pressure. In some machine designs, the larger-bore cylinder’s additional force allows the lift arm geometry to deliver the required hitch lift capacity with a shorter range of cylinder travel — the linkage can be more compact or more direct while still reaching the required implement height. The 180 mm stroke at 535 mm mounting distance still produces a 715 mm extended length, which is a significant installation dimension. The shorter stroke relative to the 200 mm subgroup reflects a design choice about the balance between force output and travel range for the specific machine the TC2104.55JD.010 serves.
110 mm Bore: Force at the Upper End of This Range
At 110 mm bore, piston area is approximately 9,503 mm² (π × 55²). The step from 100 mm to 110 mm bore increases piston area by approximately 21% — from 7,854 mm² to 9,503 mm². At 160 bar reference pressure, theoretical extension force is approximately 152.1 kN.
| Bore | Piston Area | Force @ 160 bar | Force @ 180 bar | vs 100 mm |
|---|---|---|---|---|
| 100 mm (TF1204) | 7,854 mm² | ~125.7 kN | ~141.4 kN | — |
| 110 mm (TC2104) | 9,503 mm² | ~152.1 kN | ~171.1 kN | +21% |
Engineering Reference Note: Force figures are theoretical calculations based on bore geometry and reference pressure only — not rated product specifications for the TC2104.55JD.010. Actual output depends on the system’s operating pressure, valve restrictions, and circuit efficiency. No rated pressure has been confirmed by Ever-Power for publication here.
At approximately 152 kN of theoretical extension force, the TC2104.55JD.010 generates a level of force that places meaningful demands on every component in the hydraulic circuit: the pump must produce adequate pressure and flow, the hoses must be rated for the operating pressure, the control valve must handle the flow without excessive restriction, and the lift arm structure must be capable of transmitting this force level through its pivot points and pins.
The fluid displaced per full extension cycle is approximately 9,503 mm² × 180 mm = 1,711 cm³. At the same pump flow rate as a smaller-bore cylinder, the TC2104 will extend more slowly — each millimeter of stroke requires 9.5 cm³ of fluid versus 5.0 cm³ for an 80 mm bore cylinder. This is a fundamental consequence of bore size, not a performance deficiency, and is accounted for in the machine’s hydraulic system design.
45 mm Rod: Robust Specification for High-Force Application
The 45 mm rod is the heaviest in the 535 mm group for the 80–110 mm bore cylinders — 5 mm more than the TF1204/TF1304’s 40 mm rod, and 13 mm more than the FT800’s 32 mm rod. The rod-to-bore ratio is 45/110 = 0.41, consistent with the narrow band seen across the mid-range cylinders in this group.
A 45 mm rod cross-section is approximately 1,590 mm² (π × 22.5²). The annular area for retraction in a double-acting configuration is 9,503 − 1,590 = 7,913 mm². At 160 bar reference pressure, retraction force is approximately 126.6 kN — about 83% of extension force, consistent with the retraction ratios across the rest of the group.
The heavier rod at 180 mm stroke provides improved resistance to both buckling under axial compressive load and side-loading from any misalignment in the installation. At the force levels this cylinder generates, the structural robustness of the rod and its connections is more critical than on smaller-bore cylinders — the forces transmitted through the rod end and base-end pins are substantially higher, and any wear or play in the pin joints is amplified by the higher load.
For replacement sourcing, the 45 mm rod diameter means the rod-end pin, clevis bore, and connection geometry will be notably larger than on any of the 200 mm stroke cylinders in this range. Confirm pin diameter independently — do not assume the pin from a 40 mm or 35 mm rod cylinder will fit the TC2104’s rod end.
The “JD” Designation in TC2104.55JD.010
The “JD” component of the model number is treated here as part of the model code only. In agricultural equipment part numbering, letter combinations embedded in model codes are sometimes application designations, market codes, or OEM catalogue references. Without confirmed documentation linking this specific designation to a particular machine brand or model family, no fitment claim is made on this page.
If you have sourced this part number from a specific machine’s parts manual or dealer system, that documentation is the authoritative source for fitment confirmation. For aftermarket replacement purposes, the dimensional specification — 110 mm bore, 45 mm rod, 180 mm stroke, 535 mm mounting distance — is the basis for compatibility assessment, not the model number designation alone.
Identifying TC2104.55JD.010 Within the 535 mm Group
For a cylinder with 535 mm mounting distance, the identification sequence runs: confirm stroke first (180 mm narrows to TC2104 or FS2604), then confirm bore (110 mm confirms TC2104.55JD.010 specifically).
Three-step identification within the 535 mm group:
- Step 1 — Confirm 535 mm mounting distance: Pin-center to pin-center, fully retracted. Establishes the platform group.
- Step 2 — Confirm stroke: 180 mm → narrows to TC2104 (110 mm bore) or FS2604 (120 mm bore). 200 mm → narrows to FT800, TF1004, or TF1204/TF1304.
- Step 3 — Confirm bore: 110 mm within the 180 mm stroke subgroup → uniquely identifies TC2104.55JD.010.
| 535 mm MD + Stroke | Bore measured | Model identified |
|---|---|---|
| 200 mm stroke | 80 mm | FT800.55A.012 |
| 200 mm stroke | 90 mm | TF1004.55.8 |
| 200 mm stroke | 100 mm | TF1204.551.1 / TF1304.55.012 |
| 180 mm stroke | 110 mm | TC2104.55JD.010 |
| 180 mm stroke | 120 mm | FS2604.55D4.010a |
152 kN of Cylinder Force — and What That Does Not Tell You
At approximately 152 kN of theoretical extension force at 160 bar, the TC2104.55JD.010 generates a high force output relative to the cylinders at lower bore sizes in this range. That force figure represents the push at the cylinder rod tip along the cylinder axis. It does not represent the tractor’s hitch lift capacity.
The conversion from cylinder force to hitch lift capacity runs through the machine’s lift arm geometry — the length of the arms, the cylinder’s attachment point on the arm, the angle of action at different positions through the stroke, and the mechanical efficiency of the pivot joints. Tractor manufacturers publish rated hitch lift capacity figures based on standardized whole-machine testing. Those figures and the cylinder force calculation are related quantities, but they are not the same number, and one cannot reliably be inferred from the other without knowing the specific machine’s linkage geometry.
Measuring for TC2104.55JD.010 Replacement
Within the 535 mm group, the TC2104.55JD.010 is confirmed by: 535 mm mounting distance, 180 mm stroke, and 110 mm bore — in that order. The 45 mm rod diameter provides a final confirmation of the end-connection dimensions.
| Measurement | TC2104.55JD.010 Value | Method |
|---|---|---|
| Mounting Distance | 535 mm | Pin-center to pin-center, fully retracted |
| Stroke ← confirms subgroup | 180 mm | Extended pin-pin (715 mm) minus retracted (535 mm) |
| Bore ← confirms model | 110 mm | Inside barrel diameter; uniquely identifies TC2104 in the 180 mm stroke subgroup |
| Rod Diameter | 45 mm | Calipers on clean rod; confirms connection geometry |
| Rod-end pin diameter | To be measured | Calipers; will be larger than on 40 mm or 35 mm rod cylinders |
| Base-end pin diameter | To be measured | May differ from rod end; measure separately |
| End connection type | To be confirmed | Clevis, eye, or other at both ends |
| Port specification | To be confirmed | Thread type and size, number of ports, location |
On pin wear at large bore: At the force levels a 110 mm bore cylinder generates, the pivot pins at both mounting ends carry substantial loads. Worn or oversized pin bores in the machine’s brackets — common on high-hour machines — can create play in the mounting that leads to side-loading on the cylinder rod. Before fitting a replacement, check pin bore diameters in the machine’s brackets against the pin diameter. Excessive clearance at the pivot pins should be addressed at the same time as the cylinder replacement, rather than letting it continue to impose side loads on the new unit.
Fault Diagnosis on Large-Bore Lift Cylinder Systems
On a machine using a 110 mm bore cylinder, the hydraulic system is operating at relatively high force levels. Circuit-level faults — pump wear, valve leakage, hose restrictions — have proportionally larger effects on performance than on smaller-bore systems, and are more often the root cause of lift faults than the cylinder itself.
Implement drifts under load
Cap the cylinder ports to isolate. If drift stops, the leak is in the circuit — control valve or check valve. If drift continues, internal piston bypass is more likely. On a 110 mm bore, even a moderate-size piston seal leak produces a visible drift rate because the bore area is large. Before condemning the cylinder, confirm the circuit is not the source — particularly the control valve, which on high-hour machines is a common wear item.
Rod damage from pin wear
Worn pin bores in the machine brackets allow the cylinder to move laterally under load, introducing side forces on the rod. Over time this produces uneven rod seal wear on one side and, in advanced cases, rod bending. When replacing the cylinder on a high-hour machine, check pin bore clearance at both mounting points. Replace worn pins or bush worn bores before fitting the new cylinder.
Slow lift at full load
At 110 mm bore, each millimeter of cylinder stroke requires approximately 9.5 cm³ of fluid. A full 180 mm extension cycle displaces approximately 1,711 cm³. If the pump is worn or the filter is partially blocked, the flow rate drops and lift speed falls — especially under full load when system pressure is highest and pump volumetric efficiency is lowest. Check pump output and filter condition before attributing slow lift to the cylinder.
Hard impact at end of lift stroke
A sharp impact when the lift reaches full height — the lift arm hitting its mechanical stop hard rather than stopping smoothly — suggests the control valve is not neutralizing fast enough, or the lift arm’s mechanical stop is set to engage before the cylinder reaches its internal stop. On a 180 mm stroke cylinder, the energy at full extension is proportional to the force level and the speed of travel — both are higher on this bore size than on smaller cylinders. Address valve timing or stop adjustment rather than attributing the impact to the cylinder.

Frequently Asked Questions — TC2104.55JD.010
What does the “JD” in TC2104.55JD.010 refer to?
The “JD” component is part of the model designation and is treated here as a model code element only. Without confirmed documentation linking it to a specific machine brand or model family, no fitment claim is made on this basis. If your parts manual or dealer catalogue cross-references this part number to a specific machine, that documentation is authoritative. For replacement sourcing, the dimensional specification — 110 mm bore, 45 mm rod, 180 mm stroke, 535 mm mounting distance — is the basis for physical compatibility, not the model code designation.
Why does this cylinder use 180 mm stroke when others in the 535 mm group use 200 mm?
The stroke reflects the specific lift linkage geometry of the machine this cylinder serves. A larger-bore cylinder generates more force, which can allow the lift arm to deliver the required hitch lift capacity through a slightly shorter range of cylinder travel — the linkage geometry at 110 mm bore may achieve the designed implement height within 180 mm of cylinder movement rather than 200 mm. The 535 mm mounting distance is shared with the 200 mm stroke cylinders because the bracket pivot spacing is a structural feature of the machine family, while the stroke reflects the specific lift arm design of the model using this particular bore size.
Can I use a TF1204/TF1304 (100 mm bore, 200 mm stroke) instead of the TC2104.55JD.010?
No. The bore, rod, and stroke all differ. A 100 mm bore cylinder generates approximately 21% less force than a 110 mm bore cylinder at the same pressure — the machine’s lift system will underperform. The 200 mm stroke versus 180 mm means the lift arm will be driven 20 mm past its designed endpoint every full lift cycle. The 40 mm rod versus 45 mm means the rod-end connection geometry will not match. All three differences make this a non-compatible substitution.
How do I confirm the stroke is 180 mm rather than 200 mm when measuring?
Measure pin-center to pin-center at full retraction (should be 535 mm) and at full extension. For the TC2104.55JD.010, the extended measurement should be 715 mm: 715 − 535 = 180 mm stroke. For a 200 mm stroke cylinder in the same platform, the extended measurement would be 735 mm. A 20 mm difference in extended length is measurable with a tape measure and clearly distinguishes the two subgroups. Measure extended length with the cylinder safely supported and fully stroked — never by hand-pulling a damaged or seized cylinder.
What should I check before concluding the cylinder needs replacement?
For load drift: cap the cylinder ports and recheck — if drift stops, the cylinder is holding and the fault is in the circuit. For weak lift: measure system pressure under load — pump wear and low relief valve settings are more common causes of reduced lift force than cylinder internal bypass. For rod seal leakage: inspect the rod surface and wiper seal condition before ordering replacement seals — a scored rod or a hardened wiper will destroy new seals as quickly as the old ones failed. For slow lift: check fluid level, filter condition, and pump output before attributing the problem to the cylinder.
What information is needed for an accurate quotation?
Reference number (TC2104.55JD.010 — include the JD designation), confirmed bore (110 mm), stroke (180 mm), mounting distance (535 mm), and rod diameter (45 mm). Pin diameters at both ends, end connection type, port thread specification and count, quantity, and machine model and year if known. Note pin bore condition in the machine brackets if there is any history of cylinder misalignment or side-load damage. Photos of the existing cylinder — both ends, side view, port detail — help confirm end-connection geometry before quotation.
