Hello everyone. I have a RCK60-24B deck with probably around 1000 to 1200 hours of use(tractor has a little over 1300 hours) and it looks like the lower gearbox seal failed while the wife was mowing with it. From what I have searched, that is about how long they last. I'm not sure how long she mowed with the oil gone.

Yesterday I pulled everything apart and cleaned the 15 years of grease off of everything.

I'm thinking I chipped the pinion shaft at the very end while trying to remove it as seen here. Will this be okay to use? I don't think the gear rides that low but I'm not sure.

The gears look okay for being run without any oil....I think.

I don't have a service manual for this deck on checking the gear backlash and I got the shims mixed up on removal. I have (2) 0.013 on one side and a 0.008 & 0.013 on the other side of the pinion shaft. I could not find any shims on the other shaft as shown in the parts breakdown.

Is there a manual out there that shows the rebuilding procedure of the gearbox? I also ordered all new bearings, seals, caps and retainer clips for the complete deck.
Thanks in advance.

Okay guys, I'm getting this thing back together but I have a question. On page S-13 they talk about putting "fuses" in between the gears and then measure the thickness to check the backlash. What are they talking about?
TIA, Todd

Fuses in this case is a soft piece of metal (use soft solder) and a mic to check the tolerance.

Well, that didn't work. One piece of solder I had was too small and the other was 95/5 I use at work. It was kind of big to use but I did and it sort of crushed it into the shape of the gear and I couldn't use my micrometer on it.

I used the original shims (that I mixed up) and placed them so that the gears are closest together. Can you use a dial indicator to measure them?
