Frequently Asked Questions

What seal kit fits the bucket tilt cylinder on a Case 621D?

The Z-bar bucket tilt cylinder seal kit and the combined lift and tilt seal kit both list 621D fitment. Match the cylinder bore and rod diameter to the correct part number, since the 621D shares kits with the 621E, 621F, and 621G. Our parts team can confirm the right kit at (800) 909-7060.

Do these seal kits include the tools to rebuild the cylinder?

The seal kits themselves contain the seals, wipers, and o-rings. Broken Tractor also carries separate hydraulic spanner wrenches, a replacement pin, and a gland seal installation tool kit for Case loader cylinders, so you can order the tools alongside the kit.

Will a 621E or 621F seal kit work on my 621D?

In many cases yes, because Case used shared lift and tilt cylinder seal kits across the 621D, 621E, 621F, and 621G. Always verify by the cylinder part number stamped on the tube, as cylinder revisions can change seal sizes.

Can I rebuild a leaking loader lift cylinder myself?

Yes. With the correct seal kit, a spanner wrench to open the gland, and a gland seal installer, most Case 621D lift and tilt cylinders can be resealed in the shop. We carry the seal kits and the rebuild tool kit needed for the job.
