RCK60-21Z Gearbox trashed

[BHarrison]

Well, on one of my routine checks, i noticed my gearbox had lost all fluid. I refilled, used it for about 2 hours, and noticed oil on top of the deck.

I disassembled it today, and best I can tell the horizontal shaft, it's gear, and the housing are the only parts left that are good.

It will likely be cheaper to replace the entire gearbox than replace every bad part in it.

Anyone have any tips on part sourcing, or where to get a gearbox?

thanks

I would first check with your local Kubota dealer as s/he may have a number of used decks lying around and you might find a good gear box on one of them. Or s/he may know where to get a new or used gear box at a reasonable cost, or a new gear box may not be all that expensive. I have scrounged a number of parts off old decks at the dealer nearest me. Good luck! /forums/images/graemlins/smile.gif

I just changed the gearbox oil on mine (ZD-21 with ProDeck) this past week @ the 200 hour mark. Everything was fine. Added synthetic gear oil and man is it QUIET. This is the best quality mower I've even had, simply amazing.

SkyPup? Fancy meeting you here. How's that ZD run on biodiesel?

Anyway, i think i have about 150 hours on it, i just happen to hear that it was louder than normal, checked it and sure enough, it was out of oil. /forums/images/graemlins/frown.gif

Bummer.

If I remember correctly, there is a seal on the bottom of the gearbox that you need to keep an eye on. The one bolt above the gearbox drain is the fluid level bolt, it is a good idea to check the level every 10-20 hours when you grease the bearings. Open that bolt up and if no 90wt gear oil leaks out, add enough so that it does.

I was able to change the oil withoug removing the deck using 60ml horse syringes.

The ZD-21 PRODeck is one of the most heavy duty QUIET mower setups I have ever seen!


I don't know how it runs on biodiesel because the quality of biodiesel is so poor I would not risk using it in my equipment.

$724 for gearbox assy. /forums/images/graemlins/frown.gif

YIKES /forums/images/graemlins/blush.gif

I will be checking the fluid level more often myself!

Even if you replace just the bad parts how do you know the others aren't compromised. I know $724 is a bunch but piece of mind might be worth it.

I always wondered why my maint. schedule says to replace the bottom gearbox seal every other year.

I'll be checking my oil level more often. . . .

Kubota will NEVER get that kind of money from me. **** I paid near 10 grand for the mower itself. The 60" deck new wasnt but like$1800.

I plan to have the bearings and seals matched up at a local industrial supplier. The gears and splined shafts are a different story. The same set of gears I paid $52.00 for 2 years ago now sell for $150.00! What kind of ***** is that? I would expect that from john deere, but geez. ***?
