725 Trans Reassembly Ques with PICS

Recommended Posts

fpappal
I am putting my transmission back together and I notice to issues. 1. The gear that I am pointing to in the first picture is ever so slightly rubbing on the gear beneath it. Is that normal? I have one washer underneath it which is what I found when I took it apart. The shaft is called the "second intermediate gear shaft". The gear it is rubbing on is resting on a snap ring and cannot go any lower. I have a service manual for a similar machine and it talks about fiber washers, but this transmission did not have any when I disassembled it. 2. The second picture shows my pencil pointing to a gear on the "input shaft assembly". In this position it is only meshing with the other gear a little less then half way. Should these two gears be totally in line with each other or is this normal to have them mesh like this? I took this transmission apart a couple months ago and at the time I was very careful to keep track of all my washers. It is very possible that one went missing but I am pretty sure I have them all. Any suggestions? Is there an actual 725 service manual available? Thanks

If you download the service manual for your tractor there will be a transmission tear-down section in it. I did a three speed a while back to put into a 616 yeoman that I got in a box in pcs. I noticed that the washers are not all the same, there are flat ones, and then ones that are a bit thicker and have a step on the face. The manual shows which goes where, maybe you got them turned around? I did that on my first assembly attempt. As far as the gears in pic 2, if they are all in the right places, they might pull a bit closer together when the case is dropped over the ends of the shafts. I don't remember if there was that much room between them or not. The book is a great help, download it if you don't have it. You can enter the mfg. number of the tractor in the box on the home page of the site here and it will slow you what is available for books. Steve

Good luck, these tranny's are not hard to work on if you take your time. john u

ok thanks. I did download that manual when I was taking it apart. I only found one washer that actually has a step, all the others are pretty similar except for diameter. Maybe I am just being overly cautious because I do not want to take this apart ever again!!

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
