yj clutch master and slave replacement
 
I recently ordered a crown automotive master and slave clutch assembly worked great for about a month until the plastic slave cylinder blew out so I contacted quadratec and they sent me a replacement part through crown automotive which took 5 weeks to come inthe replacement worked great for about a month until the master blew on the replacement . Has anyone else had anything similar happen ? Could there be an underlying cause or did I just get two faulty parts?

Ensure that u are properly installing the slave retainer and that ur slave is seated flush on the front bearing retainer. Are u running stock engine trans? If ur stock and installing slave properly id say try a different parts store for ur next slave. Ive had batches of parts such as waterpumps on the 318 I went through 4 in a month before going to a different store and now ive been running that one three years. Batches sit in the warehouse and seal degrade making the entire stock warranty issues.

Pre 94??? Internal slave cylinder I assume no info in profile. Either way when you install the internal you have to make sure it is positioned on the alignment pin on the trans front bearing retainer there is apin there. Next you have to install the 2 o-rings carefully and then insert the line and install the retaining clip. Leave the plastic strap on the piston it will break free first actuation of the clutch. Once assembled be careful how you yank on the slave cylinder input line you can upset the seal of the o-rings at the input spot of the slave cylinder.

External slave is no issue and they seem to all be plastic now. Pretty straightforward install 2 bolts tightened simultaneously with the plastic strap on until first activation.

Bleeding the internal is like doing old fashioned brakes through the bleed nipple. External some new ones don't come with a traditional bleed nipple. You will find a set screw which will let you gravity bleed for s start. If it didn't say in the instructions how to bleed the new externals here is a quick shot and yes it is real and works just sounds stupid.

Before you install the external slave without a bleed nipple, like I said use the set screw to initially gravity bleed the cylinder and tighten. With cap off masetr and full take the slave cylinder in hand and actuate the piston 20 cycles while pointing the piston at the ground. The air will travel back up into the master. Check fluid level and repeat. When finished service the master and install the slave cylinder with the two bolts and the plastic strap still iinstalled.

It seems to be hard to find good quality parts now a days but when you find a place that carries them keep going back and cheap parts aren't always the best.

Try Rock auto at rockauto.com I have had real good luck with their parts and the prices are always good IMHO.

I replaced mine with a Luk clutch kit back in February. Have had no problems out of it. Ordered it from partsgeek.com. It was right at $100 free shipping.
