It is possible to get parts that are packaged/boxed wrong........been there, fought through it, over came the denial!
Lets see some pictures of these new parts up against the old parts and a listing of all the part numbers you've been using in this rebuild.
We'll find an answer!
You da Man Vic!!!
I'll get all of that up here tonight.
When I bought the tractor (mower), the guy had just "rebuilt" the gearbox. It came apart shortly after I got it and I thought that the bolt, that holds the pinion shaft had just come loose. So, I put it back together, the way it came apart, without really checking everything over... stupid me. What I mean by "came apart" is the belt started popping off and then I found loose pulleys and broken seals.
When it came apart this time I really started looking and found bad bearings, bad gears, the pinion shaft was bent, and the main shaft and pulley were worn out (where the feather key goes). I also noticed that the pinion shaft was not fully engaging the end bearing where the bolt goes.
What I realized was that the bearing on the other end was on the inside of the collar which made the shaft too short. Or so I thought anyway. So, I ordered all my parts and went to install everything and am finding the shaft to appear to be too long with the bearing on the outside of the collar, like the parts diagram indicates. Just for giggles, I tried the new bearing in the new shaft, on the inside of the collar and it won't slide over the shaft. It fits beautifully over the outside portion of the shaft.
Obviously the bearings need to be seated inside the snap rings. I notice there appear to be two grooves. One on the very outside of the opening and one deeper in. However, if one were to attempt to use the outermost groove for the snap ring, there would not be enough room for the seal.
As far as the parts go, the new ones are the same as the old ones. This is what led to my question because I wondered if they substituted a different box and I was buying parts for an original gearbox when I needed them for some other box. Based on what you are saying, I am not as handy as I thought and must be doing something wrong.
Thanks again for the response Vic. I'll post all detail tonight - off to work now!
