Product Description

6803472 is an aftermarket hydraulic cylinder seal kit referenced for selected older Bobcat compact loaders and skid-steer loaders. It is a 1-in. rod × 2-in. bore cylinder repair kit. Its installation position varies by machine: it is referenced for lift-cylinder service on some models and tilt-cylinder service on others. This makes the original part-number reference especially useful for distributors and repair shops managing legacy-equipment stock. Do not select this kit only by cylinder function name, as the same machine family can use different lift and tilt cylinder sizes. Ruijueparts supports direct part-number quotations, multi-SKU purchasing lists, older-equipment sourcing, and neutral or customer-specified packaging.

FAQ

Q1: Is 6803472 a lift cylinder seal kit or a tilt cylinder seal kit?
A: It can be either, depending on the Bobcat model. For example, it is referenced for lift-cylinder service on 440B and 443, while several 444–722 series machines use it in a tilt-cylinder application.

Q2: What cylinder size does 6803472 fit?
A: This reference is for a hydraulic cylinder with a 1-in rod and 2-in bore. This dimension is useful for workshop confirmation when an original part number is not available.

Q3: Can I use 6803472 for any Bobcat lift or tilt cylinder?
A: No. Lift and tilt cylinders can use different dimensions even on similar loader models. Match by the original part number first; use machine model and cylinder function only as supporting information.

Q4: Can distributors order this part number for older loader inventory?
A: Yes. Send 6803472 and the required quantity for direct matching and quotation. Ruijueparts can also help consolidate legacy Bobcat seal-kit references into one purchasing list.

When budget aftermarket makes sense

OEM seal kits are the right choice when machinery is under active warranty, operating at peak duty cycles, or when failure risk is unacceptably high. Budget aftermarket—like Ruijue Parts—makes sense in these common scenarios:

Older or end-of-life equipment

When a machine is aging out of your fleet, OEM parts cost more than the job warrants. A budget kit extends service life without over-investing.

Secondary or backup machines

For machines used infrequently or on lower-intensity tasks, premium OEM pricing may not be justified.

OEM parts unavailable or on long lead time

When OEM stock is out or delivery takes weeks, an available aftermarket kit gets your machine running now.

Fleet maintenance on a fixed budget

Repair shops and fleet managers running high volumes of machines often balance OEM and aftermarket across their portfolio based on criticality.

Installation guide

1. Depressurize the hydraulic system

Fully retract the cylinder and relieve system pressure before disassembly. Never work on a pressurized circuit.

2. Remove and disassemble the cylinder

Remove from the machine. Unthread the gland nut and withdraw the piston rod carefully to avoid surface damage.

3. Clean all components thoroughly

Clean the bore, rod, and all metal parts with a lint-free cloth. Contamination introduced during reassembly accelerates seal wear—this step is especially important for budget-grade seals.

4. Inspect the rod and bore

Check for scoring or pitting. Budget seals are more sensitive to surface imperfections—address rod damage before fitting new seals.

5. Install the seal kit

Lightly coat each seal with clean hydraulic fluid before installation. Use proper seal drivers — not screwdrivers or sharp tools — to avoid nicking the sealing lip.

6. Reassemble and pressure test

Torque the gland nut to spec and cycle the hydraulic system under no-load conditions. Inspect for leaks before returning the machine to service.

Maintenance tips

Inspect every 250–500 hours

Budget-grade seals may have shorter service intervals than OEM. Inspect rod seals for moisture, oil film, or weeping more frequently and replace proactively.

Keep hydraulic fluid clean

Contaminated fluid degrades seals faster — this applies especially to non-OEM materials. Replace fluid and filters on schedule.

Protect exposed rod surfaces

When storing equipment with cylinders extended, protect rod surfaces from corrosion and debris to preserve wiper seal life.

Ensure Proper Installation

Avoid using sharp tools during assembly to prevent nicks or scores on the seal lips. Pre-lubricating all components with clean hydraulic oil is recommended to ensure a smooth fit into the cylinder grooves.
