4.11 R180 problem

Recommended Posts

So I found a 4.11 R180 to swap into my 260z. When I pulled it, I dropped it on accident and dirt got in the side bearings. I took the side retainers off and cleaned them really good. When I went to put it back together I started thinking that I may have messed up big time by removing the side retainers because of the tolerances involved. My hands were working faster than my head. I was so worried about the dirt and sand that I lost the bigger picture.Photo434.jpgI don't have a 200sx manual to check yet, but from the Z manual it looks like I may have to set the backlash? because I removed those parts?

How many miles are on it? I did the same thing (took the sides off) and my friend told me to get new bearings for it anyway. I believe it would need to be reshimmed anyway, as there should be shims behind those parts.

 

I had the fortune of finding two though, ones in my car now and the other on a shelf with an LSD center center waiting to go.

I got it from a parts yard and the odometer read 137xxx miles. Reshimmed huh? Would I turn to a machine shop or a specialty shop? I was going to put the 'button' in it from the older style r180 so I could bolt my 260z yoke into it. Would you happen to know if the side gears have to come out to install that button?

I found a driveline shop. 75 bucks to have it checked out. Another 75 or more to have it shimmed or more. Beta motorsports said a cross shaft has to come out to install the buttons. Its looking like a lost cause at this point. I wish the FAQ would have mentioned you have to be a driveline specialist to install the buttons correctly.

John, I am the master of disaster. I'm the reason Murphy's law exists. So I'm trying to circumvent the impending disaster. If this was a generic plentiful z r180, sure, full speed ahead. I don't come across these very often, and with me holding the tools it is high risk. I'm willing to try it, but only if I practiced on a different r180 first. But something lucky happened. Now I need your wisdom, and the wisdom of the members here. I have located a needle in the haystack... First generation Maxima CV axles for sale! I also ran into a problem. I saw a build thread saying the maxima cv axles are too short to fit a S30. I thought the maxima axles were the key according to other posts. So we have conflicting information. Does anyone have information to share about clip in CV axles that will help me?
