Re: 1978 wheelhorse Garden way tiller
I dont have the old books on these dinosaurs, but I think there should be some end play on the main shaft, you dont want 0.000 end play. But you dont want it sloppy either.
The bearings will always have a thrust load on them towards the rear as they drive worm gears.
If you replaced th bearing races, make 100% sure they are seated fully...had one come apart one me one time, costed me a shaft, bronze gear, and 2 bearings...out of pocket. These tillers get expensive, fast.
While you are there, remove the wheel axel shaft and examine the seal grooves...if they are worn, go ahead and replace it, same with the tine shaft...if its not smooth, it will leak oil like a sieve.
Its not uncommon for me to rack up a bill of 350-400 dollars working on one of these things...parts are spendy, and time consuming.
