Hi guys , here is an update on my 648 rear end project, got everything out and it didn't look as bad as I thought it would. So now I'm waiting on parts and seals,

Hi guys I have a question about my 648 tractor. About a month ago I was digging and removing dirt to remove a stone wall and driving to the end of my property and I the low gear would not engage anymore, no banging or grinding noises coming from it? So I finished the project in high gear with no problems. Do I need to replace the rear-end or is the differential able to be pulled out and replaced?
Sorry about the long story.

Thanks

I would recommend not driving this under power another foot at this time.

Pull the axle cover off and see what has happened. If you are lucky, this is simply broken differential bolts that are then easily repaired. Left to their own devices, a broken diff bolt can do a lot of internal and case damage.

Pull that cover and let us know what you find.

Thanks Brian, I will do that now and let you know what I find .

Well I pulled the cover and the brake idler gear chewed up and the bolts are broken and low gear just kinda floppy in there but looks
Ok. So what should my course of action be.

Well ... new bolts and nuts (as applicable). Reference the parts manual with your serial number/PIN and select the correct bolts for your specific machine:

648 PARTS

The brake idler gear is no longer available new, so you'll need to hunt that down used (forum, eBay, Facebook, etc).

Consider new axle bearings and all seals/gaskets when putting it back together. Right time to get it all done.

Well I finally got it all pulled apart and not as much damage as expected 😅 so now I get to put it back together once I get all the parts and seals. Here are some pic's.

I have had four of these apart from my own tractors and have never come across any problem what so ever. What causes the bolts to break on these?

Keep the Peace

I think I was shifting from low to high and still moving a little with a full load in the bucket and caused the bolts to break my bad lol.

Well here's another update, the rear-end is back in and working great 👍 I was in a working mood so de-carboned the heads and cleaned up the valves lapped, all new gaskets. Ready to do some work with this 648 again.
