8n differential

[Jonnyzebra]

What is the best way to access the differential on a 48 8n. Does the tractor need to be split? I just want to inspect it for source of noises. Right side axel and outer bearing seem fine. Jon

Drain the fluid and open the round inspection plate on the right side. If you need to see more you can remove the seat and open the top containing the 3 pt. lifting mechanism. If you need to do this I'd suggest you get a repair manual as some care must be exercised in reassembly.

bum info.

you can't see the diffy from the inspection cover or the hyd top cover except for a lil 2" hole.. might as well pull the pto shaft and look thru there..


pulling the left axle trumpet will let you remove the ring gear and chunk.

to remove the pinion you'd have to do a rear split.


is this just a inspection looksee.. or are you really feeling / hearing something..

here's a pic of an 8n diffy..

notice the casting seperates the ring gear area from the hyds section...

notice that the inspection covers are ahead of the ring gear compartment as well.

there is a small casting hole about an inch in diameter at the very top of that ring gear casting area that, if you removed the top cover that you could look down into and see a lil bit. if you were a crab and yer eyes were on stalks.. might be ok.. ditto witht he pto shaft hole... if you could stick yer eyes out on stalks and look in and up ya might see something. otherwise.. I'd pull left trumpet.. that way if you need to fix something.. you can remove chunk that side..

shop crane and laod leveler makes an easy way to lift the axle trumpet as an assembly with the axle and brakes and hub intact.. just pull the wheel and center, and then unbolt trumpet after supporting the casting... could have it off in 10-15 minutes if you work fast.. etc.. just a lil bit o linkage to disconnect..e tc..

Hey, 3 teeth broken on the ring gear, it must have been damaged some other time and then just let go as i wasn't stressing it at the time. Now to buy a parts tractor or locate the part used. Any sources? Jon
