If Cat cannot provide a seal kit, you have to take it apart and figure out what you need. IIRC Cat heavy equipment and forklifts are different divisions, and the heavy equipment side cannot provide forklift info or parts, you have to contact a Cat forklift dealer. If you really hussle, and everything goes right, you are looking at 1 day downtime minimum, any hiccups and it goes to 3 days or longer.
I don't know if this has been already mentioned, but we talked before as I have a cat v60b also. I have had good luck getting things I need for my forklift from HGM lift parts. I don't know about seals though but I call there and ask for April. Do you have any kind of manual for yours? Mike
