so reading all the treads on 904 builds i got a few notes.. if they are wrong please correct me. would i need a new gear pump with a HP build? should i get new bushings?
- to put 5 clutches and discs in the direct they need to be .061 clutches and .068 steels. i will have to get my pressure plate machined down on the edge so i can get clearance once the snap ring is installed. will i need different thickness snap ring? (Red racing frictions and Kolene steels)
As long as you figure your clearance correctly and had the pressure plate milled accordingly you won't need a different selective snap ring.
- 5 clutches in the front arent needed.
In only extreme cases IMO
- go with a 3.8 ratio band arm.
I use a 4.2 or 5.0 in 904's because they have a smaller front drum and band with less apply area. I also use the widest front band I can find which is usually 1-5/8" wide
- rebuild the sprag, bolt in isnt needed cause in a 904 they are already bolted or riveted into place.
Correct
- 24 Spring Return Module
As Tony said the reverse wound spring will work and save you money
- transgo TF2 kit
Yes
- put the clutches and steels in dry while trying to get the proper clearance. once clearance is achieved take apart soak in ATF then reassemble.
Yes
