Will this fit your machine?

Match the mower deck model: RCK54-23ZG or RCK54GR. GR2110 owners must confirm the installed deck is the matching RCK54GR configuration; the tractor model alone does not confirm fit. Compare the gearbox number, shafts, mounting points and pulley arrangement before ordering.

Gearbox housing, gears, shafts and a complete gearbox assembly are not included. Inspect the existing gearbox before choosing a rebuild. Verify that the included components address the parts that need replacement.

If the housing, gears or shafts also need replacement, compare the 702999 gearbox assembly replacing K5617-33102 and K5617-33100 and confirm its deck fitment.

Check the deck and gearbox number

  • Kubota RCK54-23ZG mower deck
  • Kubota RCK54GR mower deck

Match the installed deck identification and K5617-33102 gearbox application. For a GR2110 tractor, confirm the matching RCK54GR deck; the tractor model alone does not confirm fit. Compare the original components and their part numbers with the included-parts list before ordering. If the gearbox carries an older or different number, use the fitment help on this page to confirm the internal parts needed.

Rebuild preparation

Follow the service manual for your exact deck for bearing and seal installation, shim selection, clearances, fastener torque and lubrication. Record the original component arrangement during disassembly and inspect the housing, gears and shafts before reusing them.

Confirm the required lubricant and oil level before operating the rebuilt gearbox. Check for leaks and verify correct operation following the service manual. Rebuilding may require bearing-service tools and measurement; assess the work before choosing a kit.
