Frequently Asked Questions

What air filters does the Case 621E wheel loader use?

The Case 621E uses both a primary and secondary engine air filter. Broken Tractor carries the primary air filter (SKU 87430512) and the secondary air filter (SKU 87430511), both matched to the 621E. Replacing both together helps keep the engine intake fully sealed.

What is the difference between the primary and secondary air filter on a 621E?

The primary air filter (SKU 87430512) handles the main intake filtration, while the secondary air filter (SKU 87430511) is an inner safety element that catches dust if the primary is removed or damaged. We recommend keeping both in service on the 621E for proper protection.

Does the air precleaner fit a Case 621E wheel loader?

Yes, the Air Precleaner with Plastic Bowl (SKU L30671) is a 12 inch OD plastic bowl style unit listed to fit the Case 621E. It mounts on the intake to spin out heavy debris before air reaches the primary filter.

What fuel water separator filter fits the Case 621E?

The Fuel Water Separator Filter (SKU 504054011) is listed to fit the Case 621E among other Case loaders. It separates water from the fuel to help protect the fuel system. If you want to confirm fitment for your machine, match the part number or contact the parts team.

Does Broken Tractor carry an air/oil separator for the 621E?

Yes, we carry an Air/Oil Separator (SKU 2830592) listed to fit the Case 621E along with other 600 and 900 series loaders. Because coverage can vary by serial number, confirm the part number matches your loader before ordering.
