a bum with money Posted April 20, 2017 Posted April 20, 2017 Wow! Never would have thought that these screws would be so hard to Find! M4.5-.75 x 25, are you kidding Me! My local machine shop has never heard of that size and added that there wouldn't be enough meat to tap if I wanted to go to a m5 size. If you Google it, zip, Nada, no such Animal! Has anyone ever come up with a fix using more common Materials? Studs, Self tapping? The used parts yards won't just sell screws. Can't blame em. Bryce
DirtyComanche Posted April 20, 2017 Posted April 20, 2017 I believe a #10-32 will go, or perhaps #8-32... It's 100% wrong though. Although it might or might not be working perfectly fine on my XJ. I could not find a metric fastener that matched out of the stuff at work and gave up.
big66440 Posted April 20, 2017 Posted April 20, 2017 Is there enough material where you can tap and rethread it? If I'm not mistaken the size you need would be 4 x.75. Here's a link https://www.fastenal.com/products/details/MS2530075A20000
a bum with money Posted April 21, 2017 Author Posted April 21, 2017 Yeah, a M4 would be to small. The old timer at the machine shop didn't think a M5 would even hold after retapping. I going to check to see if a #10 or #8 Machine screw will work, haven't tried that yet. Whatever I do its going to be permanent. What ever possessed jeep to use such a unique Size? As far as I found, it only has a single use! Bryce

schardein Posted April 21, 2017 Posted April 21, 2017 Are you looking for some? I may have some if 4.0ho stuff is the same?
Dzimm Posted April 21, 2017 Posted April 21, 2017 Just go to a pick and pull and get a cheap part you could use and snag the hardware you need while you're there. As far as they know it came off with the part you're buying.
a bum with money Posted April 21, 2017 Author Posted April 21, 2017 These TPS screws only were used on the renix systems 87-90, I 99% sure of that. Just go to a pick and pull and get a cheap part you could use and snag the hardware you need while you're there. As far as they know it came off with the part you're buying. Yeah, thought of that too

This is why I hate automotive bolts, they always seem to be a stupid 'custom' size. I had to buy 2 whole Shackle kits for my XJ just for the bolts cause nobody had them anywhere close to me and I needed them that day.
a bum with money Posted April 21, 2017 Author Posted April 21, 2017 They came in the box with my new TPS. When?, what brand?,p/n? don't leave me hanging bro!
cruiser54 Posted April 21, 2017 Posted April 21, 2017 They came in the box with my new TPS. When?, what brand?,p/n? don't leave me hanging bro! Napa. came with 2 new funky washers that go under the screw heads also.
HOrnbrod Posted April 21, 2017 Posted April 21, 2017 The HO's use common 5mm screws, available anywhere in any head style you prefer. :thumbsup:

a bum with money Posted April 21, 2017 Author Posted April 21, 2017 Well I've solved the problem. I'm going to use ez lok inserts to accommodate a M4-.7 screw. By using a Allen head socket screw, I'll be getting a much higher grade than the original screw, and still have room for adjustments. I really didn't want to spend 50$ for 2 soft screws and a part I may or may not use. Bryce

"ABERRANT" or "DEVIANT" would be more apropos. :rotfl2:
DirtyComanche Posted April 21, 2017 Posted April 21, 2017 I didn't realize the Renix screws were different. My XJ has a HO throttle body, so there probably isn't a standard screw that fits the Renix.

Considering that out of the MJ's production run from 1986 to 1992, HOs only accounted to the last 2 years of that. 5 of the 7 years were Renix.
