info on my 1989 170 franklin

[cowboyup]

I bought a 1989 170 franklin grapple skidder today, it has a 453 Detroit with the 4 SPD auto. I want to completely service it before running it much, but have no idea as to fluid types and capacities. Any info is greatly appreciated. Thanks.

On the newer 170s they are in engine compartment right hand side sitting in the seat. They are canister filters.
