Hydraulic Clutch Retrofit?

[69sixpackbee]

Has anyone here done a hydraulic clutch retrofit?
If so, what pieces did you use?
Thanx,
Bud

i havent done it, but i have seriously considered it... the peices i was planning to use would be a bellhousing from about a 85-89 4 speed (these are removable like the older ones, its just a SM465), and order a slave and master cylinder for a "89 chevy k2500, new body style, 4 speed, 350"... the reasoning behind this is they are metal, and the resevoir is attached to the master cylinder, not seperate like the old body style. youll also need a throw out fork, throw out bearing, and i think the clutch is different. if you have the old type of starter that bolts to the bellhousing, youll also need a new starter.

so, in short, here is a list

• bellhousing
• master cylinder
• clutch rod from pedal to back of cylinder (this does NOT come in the kit for the older cylinders, and can only be got through a dealership. i have some that will work from a 94, which has a plastic master cylinder. if you need one send me a address and if i have an extra its yours)
• slave cylinder
• length of metal brake tubing
• tubing bender, and cutter
• adapters to put a bubble flare fitting on the ends of the tube (or if you know a shop that can do a bubble flare, you can have that done)
• clutch and pressure plate
• throw out fork
• throw out bearing
• starter
• and if your changing from an auto, youll need a pilot bearing/bushing

i think thats all i can think of that is different that youll need

Good post! I have been considering this as well. Blue_71, thanks for posting all of that info. Do you know what size flywheel the 85 - 89 4 speed bellhousing will accept (153 or 168 tooth)? I have ran across other information on this subject and have been told that they are different from small block to big block. Anyone else have more info, or even better yet any pictures??

thats a good q chevy farmer, i dont really know though. i would think that any flywheel would fit in it, but im not sure

another thing i forgot to mention-- you can also use a bellhousing from a NV4500 i *think*, its removable just like the SM465 is, and has the correct engine bolt pattern.. not sure if the bolt pattern to hook to the trans is the same though
