RowdyRebel Posted March 23, 2018 Share Posted March 23, 2018 So I've been having this issue where my clutch is not maintaining adjustment. Started the other day as I was limping it home (front diff issues...done got another new one of those now)...the dadgum thing instead of having a little free play got to where it was stupid tight...as in it was completely disengaged before it would trip the clutch switch. I adjusted it to get it down to the local Mack (they put in another ReMack front diff) and I asked them to look at the clutch. "Nothing we can see wrong with it" they said. So today, I'm running and the clutch is gradually tightening up again. So, I adjusted it again at my 1st drop before heading on down the road to grab my backhaul. I noticed a couple bolts missing between the clutch and transmission...odd...but didn't really dawn on me. Anyway, clutch was snugging up some more on my way home, so I got under it with the creeper and found my problem. I've only got 4 bolts left holding the transmission to the bell housing...2 on the passenger side, and 2 at the bottom. I tried moving one of the bottom bolts to the driver's side, but apparently those holes are a little sloppy. Pretty sure the bolts are M10x35 1.25 pitch...was going to see about picking up some more to replace the missing bolts, but now think I'll have to see if I can't find M12 in a 1.25 pitch to re-tap the holes a little larger. If that won't work, I'll have to see about those helicoil things to repair the threads to the proper size. Anyway, snugged up the bolts and it pulled the transmission back up tight to the bell housing, and wouldn't you know the clutch pedal had about 60% free play? So, I had to adjust it back again to set it right. At least now I know if the clutch starts seeming like it's not maintaining adjustment, that I need to crawl under there with my 15mm wrench and snug it up again to get it back where it needs to be. Hopefully it gets me to the weekend where I'll have a couple days to see what I can do to fix it proper. Quote When approaching a 4-way stop, the vehicle with the biggest tires has the right of way!
