Clutch Conversion
Hello, My name is Murrel, I'm New to this forum.
I have a 71 chevy C-10, and I have had some issues with the Clutch linkage, so to save myself the headach of always fixing the damn thing, I have decided to convert the manual linkage to Hydraulic.... the Throw-out bearing im going to purchase is kinda hefty on the price, but worth it in my oppinion, the link is: http://www.mcleodind.com/application...OB_BoltOn.html its number 1327 on that page. Im having trouble deciding how to go about this, any idea, hints, tricks, anything would be helpful, thank you.

Re: Clutch Conversion
I've got that same McLeod hydraulic t/o bearing in my '69, which has a Tremec 5spd in it. I used a Wilwood master cylinder to actuate it and it works great. I have a 12" Centerforce dual friction clutch and the pedal action is very light compared to the nature of the clutch. yes, the mcleod unit is pricey, but it'll give you room if you want to add headers later, and for me, it has been trouble free and very smooth. I'm sure with a stock clutch the pedal will be almost effortless.

Re: Clutch Conversion
If you are breaking linkage parts, you have something out of whack. One of the pieces is not adjusted correctly. My original linkage went 300k miles in the Jimmy. I replaced the upper and lower rods and I welded up the holes in the bell crank and re-drilled them. NOTHING was round at that point. Has another 50k on it since then.
If I was to do a hydraulic clutch, I would be tempted to get a later model bellhousing and use an external slave rather than the hydraulic throwout bearing. For your 3 speed, you could use the bellhousing from an '84-'87 Corvette with the BW 4+3. For people with an large bore trans (SM 465) you can get one from a truck. My '86 K30 dually has a hydraulic clutch setup.

Re: Clutch Conversion
So, I've been looking at converting to hydraulic as well. I feel that I've got about an issue a year in dealing with the mechanical clutch set up, whether it's a bent/broken zbar, bolts backing out of the block, bending the lower link... I did happen to run across this as an alternative to the hydraulic throw-out bearing. While I'm sure the bearing works well, I question that you'd need to replace it every time you had to replace your clutch.
Anyway..... http://www.novak-adapt.com/catalog/kit_hcrc.htm It's a hydraulic clutch slave retrofit for Chevy 90 degree bellhousings. |

Re: Clutch Conversion
ok, so I have done some diggin and I found these three products that I think will do the trick nicely
http://www.jegs.com/i/Wilwood/950/260-1333/10002/-1 http://www.jegs.com/i/Wilwood/950/260-3376/10002/-1 http://www.jegs.com/i/JEGS/555/63047/10002/-1 since it is a Pull type slave, im going to make a bracket that will attach to my after-market floor shifter bracket, 72 inches is plenty long enough, heck it might be too much, but at least its not too little, if need be I can cut and flare the line myself, I have alot of tools I never use, like a line bender, a flare tool, and a line cutter, might as well dust em off, and give me a reason to tell my wife to quit nagging me about buying tools I will never need, lol.

Re: Clutch Conversion
I build clutch linkages out of 3/8 solid rod and aircraft heims ends. It's relatively inexpensive and there is no way they are going to break or bend. Figure 50 bucks to do the whole job.

Re: Clutch Conversion
I thought about building a rod myself, but I also would like the clutch to operate easier, I have a bum knee, and in stop and go traffic it hurts....
