3020 with hyd broken coupling

Robert23239 · Aug 10, 2019

Coupling and crankshaft pulley broke . I was thinking maybe the front pump caused it . Should i be able to turn pump by hand ?

Anyway to test test ? Hate put all back together and than find pump bad
Also little A frame holding pump is cracked on one side .
Maybe the frame cracked and help sanp the pulley ?
And i want to change to cooling hyd system to the newer one . Whiich has sep tank and is plumbed is series but i need diagram to plumb it and cant seen to find one ??

Does 4439 front pump fit 3020 ?
Thanks

My guess is broken pump bracket causes pump drive coupler & damper to break. One should be able to turn pump by hand. 3020 & 4430 should interchange

Sounds like your pump locked up...

Yes i believe the pump has gave up the ghost .
Hard to impossible to rotate by hand .

Thanks for the help
