The front cover on my tractor has an engine
oil leak. Is it possible to remove hydraulic
coupler, and harmonic balancer pulley
without removing the fan shroud and radiator
to remove cover and replace gasket? To me it
looks like there isn't enough room and the
frame has a taper to it and it wouldn't
allow the cover to come off anyways.
 
You will take the shroud loose to remove the fan, but remove the alt/gen then shroud and fan, then remove your coupler and dampner and go to town on it.
 
You will do better by removing the radiator, it's easy to take out and gives you the opportunity to clean it up good..
 
That's for sure ! I spent most of my years working on 2 cyl. models and you also know what a pain pulling a radiator in those are !
You can imagine how easy I found the 4020 radiator to remove !
