Frequently Asked Questions

Which air filter fits a Case 850C dozer?

Broken Tractor carries the Primary Engine Air Filter A34445 (SKU D80480) and the Air Filter SKU D78336, both of which fit the Case 850C and 855C dozers. We also offer an Air Cleaner Cap (SKU 277377R1) and an Air Pre-Cleaner with Plastic Bowl (SKU 258539A1) for these machines. Match by part number and your air cleaner configuration before ordering.

Does the cab fresh air filter fit both the 850C and 855C?

Yes, the Cab Fresh Air Filter (SKU F64318) fits both the Case 850C and 855C dozers, along with several other Case models. It handles fresh air filtration for the cab. Confirm your machine's configuration by part number before you order.

What is the difference between the primary engine air filter and the air pre-cleaner?

The Primary Engine Air Filter (SKU D80480 or D78336) is the main filtration element that cleans intake air before it reaches the engine on your 850C or 855C. The Air Pre-Cleaner with Plastic Bowl (SKU 258539A1) sits ahead of the air cleaner to remove larger dust and debris, extending the life of the primary filter. Many owners run both together for better protection.

How do I confirm the right air filter for my Case 855C dozer?

Verify fitment by matching the part number to your machine and checking your air cleaner configuration, since setups can vary. Broken Tractor lists exact fitment for each filter, and our team can help confirm the correct part. Call (800) 909-7060 if you need assistance matching a filter to your 855C.
