Alright so I have a question about this piece: if you know where it goes I would give you thanks times a million. I have read manuals and did research I still just can't figure it out. Thank you.
Any chance there is a part number on that part? Cat is pretty good about stamping numbers on most every part. Also a S/N would help identify the machine a little better. Did you remove this or did you get tossed in to the job while it was laying in pieces?
Bolts to the intake manifold on LH side?? http://equipmentforsalebuy.com/wp-content/uploads/1996-caterpillar-d5c-lgp-iii-15.jpg
