Clutch Slave Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

lts70 · 10-01-2012, 12:54 AM

Many years ago I installed an nv3500 transmition out of a 1992 Chevy truck. I installed the clutch set up from the same truck. The slave cylinder is now leaking and needs replacement. I would like to use a a wildwood style replacement but I am not sure if it will work as the linkage portion is different. Any advice would be apriciated. The rock auto link below is the style I have now and the wilwood link is what I would like to use if possible.

The slave cylinder i have is the same type you want to use. I not sure of the linkage on the oem style, but the linkage on the willwood is simple to use. Go to Speedway motors, this is where i got mine. They have the linkage parts that you will need. Plus they are priced good. They might be able to answer any questions you might have. Hope that helps.

Linkage inside cab

It would be right at home next to my wilwwod master and proprtioning valve.

From what i can tell, you should have no problem with the linkage. Might be able to reuse what you already have. The rod coming out of the wilwood is 5/16 thread on mine.

I thought I had found the adapter (NAPA part #7974) I needed but it turned out to be backwards,just my luck. I think I will just have to cut the old metric fitting off the the hard line and find a standard size fitting that will be easier to find an adapter for.

This is the type of line I have. It goes from hard line to rubber back to hard line.

Is it possiple to cut it at the rubber and recrimp a smaller line? It has 1/4" line now that is just to big to find any fittings that will work with my 3/8"-24 inlet.

After making a million phone calls and about to just have an all new line made up I got refered to Tony Stevens at Carolina Racing Supply.

And for $5 I hope I will be back on the road again. I hope this truly works.

The silver piece should go into the master cylinder. The sleeve (small part on right) and the nut should go on the hard line with only a single flare, no double-flaring required.

I just hope down the road this helps at least one guy find the fittings to go from his NV3500 to a wilwood clutch master. If it does and you read this shoot me a PM, it will make my day. Just out of curosity, is anyone watching this with intrest?

**88JRFAN** · 11-25-2012, 11:37 PM

Just out of curiousity, could you have went with a braided line instead of the hard line. Was the other end of hard line a metric size too?

Portmod7 · 11-26-2012, 12:05 AM

Glad you found a solution!

I love using tube nuts and sleeves with the single flare. SO much easier than double flare, and I have MUCH better luck with them sealing up.

I finaly got her all back to gether again. It was good to give her a drive around the block. Still need to bleed the air out to get more pedal though.
