About this replacement part

RC54-FZ21 gearbox bearing and seal rebuild kit

FLIP 707550 is an aftermarket service kit for the Kubota RC54-FZ21 mower deck gearbox. The 76577-33110 number identifies the original bevel-gear case in Kubota's parts catalog and is used here as an application reference. This kit services selected bearings, seals and retaining hardware; it does not replace the case or supply a complete gearbox.

What is included: 13 service pieces

Includes 3 ball bearings, 2 oil seals, 5 retaining clips (circlips), 2 shims and 1 feather key, as shown in the product photos. No gears, pinion shaft, bevel-gear shaft, housing, pulley or lubricant is included. Inspect the existing gears, shafts and housing before deciding whether this kit covers your repair.

Confirm the deck and gearbox before ordering

Confirm the mower deck identification plate reads RC54-FZ21, then compare its gearbox diagram and original components with this kit's photos and contents. A tractor model or the 76577-33110 case number alone does not establish that every required service part is included. Other decks require a separate fitment check.

Gearbox service requires disassembly, bearing and seal replacement, inspection and reassembly. Follow the service manual for your exact equipment, including bearing installation, shim selection, clearances and lubrication. Do not assume the supplied shims establish the correct adjustment without measurement. Text 903-320-4519 with FLIP SKU 707550, the deck model and serial number, and photos of the gearbox and removed parts for fitment help.

Aftermarket replacement part. Not affiliated with or endorsed by an original equipment manufacturer. Verify the listed part number, model, dimensions, and serial notes before ordering.

Product questions

Answers for this part.

What is included in FLIP 707550?
The kit contains 13 service pieces: 3 ball bearings, 2 oil seals, 5 retaining clips (circlips), 2 shims and 1 feather key. Compare the original components with the product photos before ordering.
Does this kit replace the complete 76577-33110 gearbox or case?
No. Kubota identifies 76577-33110 as the original bevel-gear case. FLIP 707550 is a bearing, seal and hardware service kit for the listed RC54-FZ21 application. It does not include the case, gears, shafts, pulley or lubricant. Inspect those existing components to determine whether additional parts are needed.
How do I confirm fitment and install the kit?
Confirm the RC54-FZ21 deck model and serial number, gearbox configuration and all required service pieces. A tractor model alone does not confirm fit. Follow the service manual for disassembly, bearing installation, shim adjustment, clearances and lubrication. Text 903-320-4519 with FLIP SKU 707550 and photos for fitment assistance.
