Bobcat Drive Motor Seal Kit vs Hydraulic Cylinder Seal Kit: How to Choose the Right Repair Kit
When buyers search for a Bobcat seal kit, the first problem is often not price. The real problem is identifying the correct repair position.
A Bobcat skid steer loader, all-wheel steer loader, or compact excavator may use different repair kits for the drive motor, travel motor, tilt cylinder, arm cylinder, bucket cylinder, or other hydraulic cylinders. These kits may all be described as “hydraulic seal kits” in daily conversation, but they are not the same product.
For repair shops, dealers, rental fleets, and online parts sellers, choosing the wrong kit can create extra labor, delayed repairs, returns, and customer complaints. This guide explains the difference between a Bobcat drive motor seal kit, travel motor seal kit, and hydraulic cylinder seal kit and what buyers should check before ordering.
Why Bobcat Buyers Often Choose the Wrong Seal Kit
Bobcat machines are widely used in construction, landscaping, rental fleets, farms, road work, and small job sites. Models such as Bobcat 645, 653, 742, 863, 337, S220, S250, S300, A770, S630, E50, E55, and E60 may have very different repair positions.
A buyer may only say, “I need a Bobcat seal kit.” But this is not enough.
The supplier still needs to know whether the repair is for:
- Drive motor
- Travel motor
- Tilt cylinder
- Arm cylinder
- Lift cylinder
- Other hydraulic cylinder position
A drive motor seal kit cannot replace a hydraulic cylinder seal kit. A tilt cylinder seal kit is different from an arm cylinder seal kit. Even if the machine brand is the same, the seal structure, size, and application can be completely different.
That is why the safest buying process is to confirm the part number, machine model, and repair position together.
What Is a Bobcat Drive Motor or Travel Motor Seal Kit?
A Bobcat drive motor or travel motor seal kit is used for the hydraulic motor that helps move the machine. For Bobcat skid-steer loaders, buyers may call it a drive motor seal kit. For compact excavator applications, buyers may search for a travel motor seal kit.
Buyers may need this type of kit when they see problems such as oil leakage around the drive motor, weak travel power, abnormal movement, or repair work after motor disassembly.
Examples include:
- 6659601 Drive Motor Seal Kit for Bobcat 645 653 742
- 6668198 Drive Travel Motor Seal Kit for Bobcat 863 337
These products are not for tilt cylinders or arm cylinders. They are for drive or travel motor repair.
For dealers and repair shops, this distinction matters. If a customer asks for a Bobcat 863 seal kit, you still need to confirm whether they are repairing the drive travel motor or a hydraulic cylinder. The model number alone does not always identify the correct kit.
What Is a Bobcat Hydraulic Cylinder Seal Kit?
A Bobcat hydraulic cylinder seal kit is used inside a hydraulic cylinder. The cylinder may control lifting, tilting, digging, arm movement, or attachment positioning.
Common Bobcat hydraulic cylinder repair positions include tilt cylinder, arm cylinder, and other loader or compact excavator cylinders.
Examples include:
- 7137770 Hydraulic Cylinder Seal Kit for Bobcat
- 7135547 Tilt Cylinder Seal Kit for Bobcat S220 S250 S300
- 7196904 Arm Cylinder Seal Kit for Bobcat E50 E55 E60
- 7225491 Tilt Cylinder Seal Kit for Bobcat A770 S630
A hydraulic cylinder seal kit is usually selected by part number, machine model, and cylinder position. For example, a Bobcat S220 S250 S300 tilt cylinder seal kit is not the same as a Bobcat E50 E55 E60 arm cylinder seal kit.
Tilt Cylinder and Arm Cylinder: What Is the Difference?
Many wrong orders happen because buyers know the machine model but do not know the exact cylinder position.
A tilt cylinder is commonly related to loader bucket or attachment tilt movement. For Bobcat skid steer loaders such as S220, S250, S300, and S630, and the Bobcat A770 all-wheel steer loader, tilt cylinder seal kits are often requested by repair shops and rental fleets because these cylinders work frequently during loading and attachment operation.
An arm cylinder is more common in compact excavator applications. For Bobcat E50, E55, and E60, an arm cylinder seal kit supports digging movement and is different from a skid steer loader tilt cylinder kit.
The key point is simple: do not choose only by brand. Choose by repair position.

What Information Should Buyers Confirm Before Ordering?
Before ordering a Bobcat seal kit, buyers should confirm five details.
First, confirm the part number. A part number is the most useful starting point for reducing wrong orders.
Second, confirm the machine model. Bobcat S-series skid steer loaders, the Bobcat A770 all-wheel steer loader, and Bobcat E-series compact excavators may use different repair kits.
Third, confirm the repair position. Is the repair for the drive motor, travel motor, tilt cylinder, arm cylinder, or another hydraulic cylinder?
Fourth, send photos when possible. Photos of the old seals, motor, cylinder, or machine plate can help the supplier check the application.
Fifth, confirm whether the order is for one repair, resale stock, or rental fleet maintenance. This helps the supplier recommend packaging, mixed orders, and repeat supply options.
For B2B buyers, the goal is not only to buy one kit. The goal is to avoid wrong orders, reduce returns, and keep machines working.
