Just thought I would share progress on this very neglected 2630... It has been quite the learning experience. This is also the first tractor I have split (by myself).
Here it is, after delivery. Wouldn't even start:
Found numerous electrical issues. Mainly skinned wires, missing terminals (for example, starter solenoid wires were wrapped around the lug without a crimped terminal), voltage regulator was unplugged. Finally cleaned it all up, put new lights, batteries, light switch, solenoid, and battery cables in.
Next up, the I, II, R shifter had a ton of slop and even pulled right out of the transmission. I have since learned of the parking kit that was added to these tractors. Problem with mine was, the shifter and kit was added but they reused the old bearing and snap ring. Got the correct kit with shims installed, fixed the slop.
Hydraulics - actually aside from a few leaks, this part wasn't so bad. Tractor and loader still functioned correctly. However, mine has the independent PTO which is driven off the transmission hydraulic pump and the PTO functioned very poorly. Starting with the fluid and filter change, here is the inlet screen (I expected worse to be honest).
Tractor has leaks everywhere, I always figured because of the blow-by. Full engine overhaul is coming this fall. For now, replaced leaky rubber hose fuel lines with the factory hard lines except I noticed the main line off the tank to the transfer pump (also replaced) needs to be routed under the oil cooler - that will have to wait until the full overhaul happens.
Tractor clutch always was poor, however I wanted to try to get by just a hair longer. So started mowing, noticed it wouldn't lug up a hill due to the slippage. Time to bite the bullet and split it, fix it right.
Looks like an oil bomb went off a long time ago. Oil and dirt is caked on almost an inch thick.
Flywheel with what remains of the pilot bearing:
No balancer shafts! I assume the previous owner removed them for some reason. Not good. Will come back to this later this fall, but to get these last two bushings out requires another tractor split.
Rear main seal (bad one):
Clutch disk - I expected worse, but it doesn't look great either:
Flywheel is currently being refinished, waiting on the flywheel housing gasket, throwout bearing carrier, and arms to be delivered.
Successfully installed new injectors without breaking any. Looks like one of the 4 was replaced at some point maybe?
That is all for now! Will keep updating regularly. In case anyone is curious, I believe the 2630 and the 2640 are nearly identical.
Edit: Looks like I can't figure out photos, so attaching them instead.
