Follow these steps to replace the seat cushions on your Case 850C:
1. Remove the Seat from the Dozer
The first step is to detach the seat from the dozer. This will provide easier access to the cushions and allow you to work on them in a more comfortable position. Typically, the seat is bolted onto the seat frame with a few screws or bolts. Use a socket wrench to remove these bolts and carefully lift the seat off the machine.
2. Remove the Old Cushion
Once the seat is removed, inspect the cushion and the seat frame. If the cushion is simply worn out, use a screwdriver or wrench to remove any fasteners or covers that are holding the old cushion in place. Be cautious not to damage the frame or other components during this step.
If the cushion is attached with a cover, carefully peel it back to expose the foam beneath. If the foam is damaged, it can be easily replaced with a new one. In some cases, the cushion may be glued or stapled in place, so you may need to carefully cut or remove these attachments.
3. Install the New Cushion
Place the new cushion in the seat frame. Ensure that it fits snugly and aligns properly with any mounting points. If necessary, use a utility knife to trim the foam or fabric to fit the frame exactly. Once the cushion is in place, attach it to the frame using the same screws or bolts that held the old cushion in place.
4. Reattach the Seat
After the new cushion is securely fastened, reattach the seat to the Case 850C. Align the seat frame with the mounting points on the machine and use your socket wrench to bolt the seat back into place. Make sure the seat is level and positioned correctly for the operator’s comfort.
5. Test the New Cushion
Before using the dozer, test the seat to ensure the new cushion is providing proper support. Sit in the seat and check for comfort and stability. If necessary, make minor adjustments to the cushion or seat position to optimize comfort.

Why Replace Seat Cushions?
The seat cushions in the Case 850C, like those in any other heavy equipment, are exposed to intense wear and tear. The operator's weight, frequent movement, and constant vibration from the machine can cause the foam and fabric to degrade over time. A worn-out seat cushion can:
- Decrease Comfort: A sagging or deflated seat reduces comfort, which can lead to increased operator fatigue, especially during long hours on the machine.
- Cause Postural Issues: Poor seating support can cause back pain, leading to poor posture or even long-term injury. This is particularly true for operators working in rough terrain.
- Affect Productivity: A distracted or uncomfortable operator will likely not be as focused on the task at hand, which can reduce efficiency and increase the risk of accidents or errors.
Identifying the Right Replacement Cushions

The Case 850C's seat dimensions and configuration can vary slightly based on the machine's year of manufacture and any modifications it may have undergone. Therefore, it is crucial to ensure that the replacement cushion matches the original in size, shape, and mounting points.
Here are some considerations for selecting the right cushions:
- Size and Shape: The seat cushion should match the dimensions of the original. It should fit snugly into the seat frame to ensure proper support and comfort. If you're not sure about the size, measure the existing cushion or consult the dozer's owner manual for specifications.
- Material: The material of the cushion is important for durability. Many replacement cushions are made from high-density foam that resists sagging and compression over time. The cushion's fabric should be durable enough to withstand the wear and tear from frequent use and exposure to outdoor elements.
- Compatibility with Suspension: If the Case 850C is equipped with a suspension seat, ensure that the cushion is compatible with the seat's suspension system. Some replacement cushions are designed specifically for suspension seats to ensure proper fit and function.
- Supplier: It's best to purchase the replacement cushions from a reputable supplier or directly from Case or authorized dealers to ensure the highest quality and fit. Aftermarket suppliers may also offer a variety of seat cushions, but their quality and fit may vary, so it's crucial to do some research before buying.
Replacing the seat cushions on a Case 850C requires only a few basic tools. Having the right tools will make the replacement process faster and more efficient:
