Michigandog 0 #1 Posted July 21, 2017 I have a 604 tractor with a 3 speed trans, that I'm rebuilding.. I've already replaced the axles, input shaft, and third gear, but also noticed that the reverse idler gear is bad. So I replaced that too. I also noticed that the cluster gear is worn on two gears, and after thinking about it I want to replace it too. Only problem is that I can't find one... There is one on ebay for a 312-8 and the part number for that model is 7269, and the part number for the 604 is 3525... My question is, will the cluster gear on a 312-8 tractor with a part number 7269. Interchange with the 3525 cluster gear on a 604 tractor??? Any help would be highly appreciated...

Racinbob 11,237 #4 Posted July 21, 2017 No, they won't interchange. One shouldn't be too hard to find though. I'll check to see if I have one later today. 3 Share this post Link to post Share on other sites
Racinbob 11,237 #5 Posted July 21, 2017 I had a little plumbing job to do today. I told my wife I'd only have the water off about an hour. Well.......six hours and three trips to Lowes later I got it back on Finally it was time to go 3525 cluster gear hunting. I've got two of them. They are both usable but do have some wear. Check them out and see if they are better than what you have. 2 Share this post Link to post Share on other sites

I have one coming from ebay, if it doesn't work I will buy yours... Share this post Link to post Share on other sites
Racinbob 11,237 #8 Posted July 24, 2017 Just a suggestion since you have it apart. Check your shifter rails. If the three detents are the same depth I would scrounge up some later rails that have a deeper neutral detent. Install those as well as a 3/4" stop pin in lieu of the 11/16" that you'd have if all the detents were identical. Later on they went to rails with the detents going all the way around the rail. Those would work as well. 1 Share this post Link to post Share on other sites
