Apologies for not seeing this earlier. Restoring an 825 as well and need to replace cover but still have the old one. Attached is what I have. Also, I am not aware of a filter in the hydraulic well. I have two, both external.
Howdy all, I am restoring a bobcat 825. I have almost completed rebuilding the Perkins 4-108 (new crankshaft needed). Look forward to getting advice from this board.
Go to parts4engines.com they have the best offering of parts for Perkins 4-108, reasonably priced and great customer service. Note there is an industrial and marine version of the 4-108 so make sure you get the right one. I am restoring an 825 and would enjoy hearing your experience with yours.
