The right lift cylinder seal kit depends on your machine model, cylinder bore, rod diameter, and replacement part number. The first and fifth options are listed for several older Bobcat models and the 2-inch-bore, 1.25-inch-rod cylinder size; the second targets selected Bobcat loaders; and the third is listed for Case equipment. The fourth item is an installation tool set, not a seal kit, but may be useful when fitting flexible rod seals.

This replacement kit is listed for Bobcat models including the 444, 610, 642, 643, 742, 743, and 753, along with many other models. Its stated fitment is for a hydraulic cylinder with a 2-inch bore and a 1.25-inch-diameter rod. The listed replacement numbers include OEM 6803329 and 7137769, plus cylinder numbers 6586575 and 6586671.
Best for: Owners whose model, cylinder dimensions, and part number match the listing. It was selected for its broad stated Bobcat model coverage and clear size details. Caution: Model coverage alone does not confirm fit; verify the cylinder measurements and part number before ordering.
Bobcat 7135559 Lift Cylinder Kit
This seal kit replaces part numbers 7135559, BCK-7135559, 6816537, and 6803324. The listed compatible lift models include the Bobcat 773G, S150, S160, and T190. The product name also refers to S175, S185, and S205, but the supplied feature list identifies the four models above; check the listing and machine details carefully if your model is not included there.
Best for: Buyers who need one of the listed replacement part numbers for a compatible Bobcat lift cylinder. It was selected as a model-specific option distinct from the 6803329/7137769 kits. Caution: The supplied details do not state bore or rod dimensions, so confirm fitment by part number and machine information before purchase.
Case 128728A1 Hydraulic Seal Kit
Kit King’s aftermarket kit is listed as compatible with Case part number 128728A1. Its stated dimensions are a 1.25-inch rod and 2.5-inch bore. The listed equipment types include backhoe loaders, landscapers, loaders, skid steers, Unimogs, and Uni Loaders; the product description names Case series such as 480, 580, 1830, 1835, 1838, 1840, and 1845.
Best for: Case equipment owners who can match the 128728A1 number and specified cylinder dimensions. It was selected to give buyers a Case-focused alternative to the Bobcat kits. Caution: Do not assume a listed equipment type guarantees fit; compare the cylinder and part number with your machine.
VEHIFOMO Hydraulic Seal Installation Tools
This three-piece set is an installation aid rather than a replacement lift cylinder seal kit. The product description says its tools cover rod seal installation jobs from 0.87 inches and are designed to bend flexible seals into a “kidney bean” shape for insertion into a cylinder groove. It also describes plastic handles intended to reduce slipping and smooth, polished edges.
Best for: A buyer who already has the correct seals and wants tools to help install flexible rod seals. It was selected as a related repair item because installation tools can be part of a cylinder reseal job. Caution: It does not supply replacement seals, and the listing does not specify compatibility with every cylinder or seal type.
Two-Pack Bobcat 6803329 / 7137769 Kits
This listing offers a two-pack of lift cylinder seal kits for a 1.25-inch rod and 2-inch bore. The listed interchangeable part numbers are 6803329 and 7137769. Stated Bobcat applications include models such as the 444, 500, 520, 530, 540, 643, 731, and 743, plus additional models. The product description identifies rubber and steel as materials used in the kit.
Best for: Buyers who need two kits and have confirmed the same dimensions and replacement numbers. It was selected as a multi-kit alternative to the single replacement kit above. Caution: The two-pack format may be unnecessary if you only need one repair kit; confirm the contents and fitment for your specific cylinder.
Buying Guide: How to Choose a Lift Cylinder Seal Kit
Does the kit match the cylinder dimensions?
Check the cylinder bore and rod diameter before choosing a kit. For example, the two Bobcat 6803329/7137769 options list a 2-inch bore and 1.25-inch rod, while the Case 128728A1 option lists a 2.5-inch bore and 1.25-inch rod. A shared rod size does not mean the kits are interchangeable.
Should you match the part number or the machine model?
Use both when possible. Find the existing seal-kit or cylinder part number, then compare it with the replacement numbers in the product details. Confirm the machine model and cylinder measurements as well. Model lists can cover many variations, so a model name alone may not establish fitment.
Do you need one kit, two kits, or an installation tool?
Choose a single kit when one cylinder needs service and a two-pack only when you have a use for both. An installation tool set can help with seal placement, but it is not a substitute for replacement seals. Check that the tool’s stated size range and design suit the seals being installed.
What details should you verify before ordering?
- Equipment make and model.
- Hydraulic cylinder bore and rod diameter.
- OEM or replacement part number.
- Whether the listing provides a seal kit, a multi-pack, or tools only.
- Whether the product description clearly covers your specific application.
Frequently Asked Questions
What does a lift cylinder seal kit do?
It provides replacement seals for a hydraulic lift cylinder. Damaged internal seals can contribute to hydraulic oil leakage, according to the supplied product information.
Can I choose a kit using only my Bobcat model?
A model match is helpful, but it is safer to verify the cylinder dimensions and replacement part number too. Listed model coverage does not confirm every cylinder configuration.
Are the 6803329 and 7137769 kits for Case equipment?
The supplied listings identify those replacement numbers with Bobcat applications. The Case kit in this selection is listed for part number 128728A1.
Is the VEHIFOMO product a seal kit?
No. It is a three-piece hydraulic seal installation tool set. It does not replace the seals required for a cylinder repair.
What should I do if my cylinder dimensions are unknown?
Identify the cylinder or its part number and obtain the bore and rod measurements before ordering. If those details are unavailable, confirm the application with the equipment or cylinder supplier.
