I'll look into that tractortech, I've got a full set of plates in the other clutch.
I think I might have found something wrt the 'S'stamping - in the EPC, part 21, is a square section o ring which seals the inner diameter of the piston against the clutch drum. After a certain serial number...
Well, spoke to Lee the oracle at Nick Young, and there are only 2 types of PTO clutch for the 50 series, -the one for 540rpm only is different - it has less clutch plates in it, so the big circlip fits lower down in the housing.
So I reckon the difference in mine is just in the machining, and...
The EPC shows one drum for the independent PTO (AL39262) and another for handshift PTO (AL39263), depending on serial number, after S/N 652587 it's back to the same drum as the independent PTO (AL39262).
The problem I have is that the two drums I have have totally different part numbers to the...
Well, I tidied up the best of the two drums I had and reassembled with new piston ring and hook rings.
One thing is bothering me- I measured the two drums just to check they were the same.... and they're not quite.
My original drum has 'S' stamped on the face - is this related to the 'S' on the...
Thanks TractorTech, good to know that a bit of wear is normal, I'll just take the burrs off and make sure the plates don't foul on the ridges i think.
NZ - top shaft shouldn't be moving as I have set 0.1mm preload on it, didn't measure the rolling drag though as don't have a torque wrench that...
So taking the above advice I've pulled and stripped the HiLo, PTO clutch and brake and the transmission pump.
There's a fair bit of wear in there, good steps worn in the pair of hook rings in the HiLo, and the ring gaps look pretty big on the piston rings in the pto clutch and brake. Can't seem...
Can anyone tell me what the piston ring gaps should measure in the PTO clutch, PTO brake and HiLo?
I've got steps worn in the hook rings, and the piston ring gaps look pretty big to me!!
Well, found a second hand back end, and swapped all the gearset and bearings over, set preload and backlash as per the manual. Couldn't measure 1/2Nm rolling drag on the countershaft, but set the preload as per the manual for a 2140, which doesn't mention measuring rolling drag anyway..
Only...
Yes, I would have thought, there was a hell of a rumble when you span it by hand even. Definitely movement in it too.
trying to decide if this was also the cause of the clunky gearshifts..... clutch paddles are like new, about 0.25mm wear in the flywheel and pressure plate, but flywheel...
Having studied it a bit more, I can replace the race on the inner shaft, I presume it's a heat it off and on job.
The pitting on the inside of the hollow shaft doesn't feel too bad to my fingernail.... I'm wondering if another second hand shaft would be any better, or is this marking/pitting...
So, been using the 2650 with the clunky gearbox, until the rrr rrr rrr noise that I was hoping was just normal for reverse, got louder and started showing itself under load in low box and reverse, but not high box.
So, as clutch was suspect anyway I took the plunge and took the cab off (after...
