Rear driveshaft coupler- 122

[jbrewer]

Hello OCC

I need to replace the rear driveshaft coupler on my 122. Do I need to split the tractor (or move the engine forward a half inch or so) to get it out? I know I need to remove the spirol pin(s).


(Edit, pins are out. Coupler still hung up on the input shaft end. Someone has been in here before me on the same mission I now see)



Splitting the tractor might be less of a PITA but not sure either is needed and I am sure neither is easy.




Thanks for your advice

Moving the engine forward may be the easiest of the options?

Remove the grill, lay it on a milk crate or whatever, then you will have more room to slide the motor forward so you can remove the clutch. Then split the tractor, this way you can see how much damage there is to the shaft.

You're saying I have to do BOTH?

ZZZZZzzzz ok if you lay under the tractor you can remove the coupler.

Either that or cut the tunnel open (Geesh, I hope not!!) or stand the unit up on it's tail somehow.

Do you have a set of roll pin punches and a new coupler?
You need to support the nose of the transmission and/or the coupler to drive the pins out or risk damage to the input shaft bearing and seal.
No one said this was going to be easy.
