350C Changing Fan Belt removal - options ?

Post by sullyt28 » Sun Jul 27, 2014 7:07 pm

Have this 350C thought I would change the fan belt while I have it somewhat apart. Realized the PTO shaft for the hydraulic pump is an obstacle. Figured the easiest way is to undo the 2 bolts holding the pump and slide it out to loop around the fan belt. Removed the 2 bolts and the pump does not want to budge. It's like the housing for the pump is welded to the front frame x-member. :? Anymore beats with the hammer and I'm bound to break something.

Next thought is to undo the 4 bolts on the flywheel and try pushing ahead the yoke to loop the belt through. Just curious if anyone else has ran into this issue. I suspect the pump is fairly fragile and won't take a lot of abuse.

If anyone has any feedback greatly appreciated.

I removed the 4 bolts that holds the coupling to the crank pulley and slid the coupling back on the shaft.

That worked, there was a C-clip on the shaft that had to be removed as well to get the yoke to slide forward.

How to get the pump to separate from the front x-member is still a mystery :?
