im planning on por-15 this weekend i been spraying the bolts on the skid plates alot i do have torches if needed but if one does break can i drill and tap it for a new one. has anyone have any thing like this happen to them
ok the first thing when u take the skid off support the transmission. next the skid bolts are really a pita to get out sometimes. and no u can not drill and tap the frame u have to buy a new nut sert theirs nuts set inside of the frame and u will need to replace those if u snap one. although i am running with only four right now i snapped the two center ones. and its doing just fine
some say why i say
its a jeep thing u wouldn't understand
ha hole on the back side u haven't owned ur jeep long have u no its never that easy. the nut serts are inserts that u have to buy, that the bolt threads into. u will have to grind off the old ones insert the new ones and then when u tighten them they expand in the hole to lock. ad thats why i just left mine with four
some say why i say
its a jeep thing u wouldn't understand
Ur right I haven't owned it that long got it in mid feb always wanted one but to busy playin with my trucks in the mud everyone said these were more fun and the price was right to get it as a project toy thanks for ur help I don't think ill go thru all that unless its needed
live to off road off road to live
If you're going to remove the skid plate one of the best ways to do it is to soak the bolts real good with PB Blaster. Then, slightly tighten the bolts. An impact wrench is better to remove them. Doing the latter I only broke one. It's not easy. I would only do it if you have to. If you do, replace the trans. bolt also.
I just took mine off of my 89', i heated the bolt with a plumbing propane torch and then sprayed them with liquid wrench i then put a 3' copper pipe on the end of my ratchet for a breaker bar and they all came out. The transmission shop I talked to couldn't believe they did not break, He said that it is very common to snap one or more off!
OK Jeepers... My first post. Hope this is informative to all, and humorous to some.
I recently coerced my girlfriend to purchase a 92 YJ Islander 4.0. It looked beautiful in pictures glorious in her fire truck red paint job. But when I went underneath, it was another story...
Her skid plate was held on by two bolts, opposing corner bolts. The rest were broken stubs in the frame. My first fix was the drill and tap method, only to find out about the inserts 2 broken bits later. Frustrated I Left the two opposing bolts there, worked 1 out of the 4 broken bolts out and inserted a bolt. Thinking if 2 had been ok for a little bit, a third would be a little better. (3 Weeks pass) Well after the GF drove 30 miles home one day she complained that she heard a little bit of a "clunking" noise, and that the exhaust was getting noisy, and it was difficult to shift into the 2nd, 4th, and reverse gear.... So I put the grubbies on, popped the hood, and WTF... something looked odd... I laid down, took a look underneath, and noticed that the entire starboard side of the skid plate was hanging freely. BOTH BOLTS FELL OUT! THe entire skid plate/transmission/engine was hanging from one bolt, and the engine mounts. Lol Jeep will still drive with the skid plate hanging freely. She drove 30 miles like that... "clunky"
After that I ground and pounded those babies out and welded some backing nuts on the back side of the frame. Inserted grade 8 bolts all the way round, and even added one of my super awesome custom built welded lock nuts to each bolt Now the Jeep is strong, and the Girlfriend is happy.
My hands are still dirty...
If there was six, there shall be six...
Side Note: My Mechanical Engineer General Electric Field specialist Dad has taught me a trick to stuck bolts... Acetone + ATF It does wonders. Let it soak, squirt some more, let it soak, then put some heat on it. Be careful, Acetone is VERY flammable. Dad says " If it works on Frame 5 gas turbines, It will work on a Jeep." Dad got started his experience at age 14 tooling on a Ford GPW.
Ok, the info here is great. I just removed the skid plate and ordered a new one. Most of the holes for the tapered head bolts had rusted to the point where they were barely holding the plate on. The trans mount had separated and the skid plate was polished where the mount was rubbing, but it was 2 inches to the starboard side of where the mount was located. One bolt snapped off, so if anyone has pictures showing what the original nut plates in the frame look like and what I need to do to grind and knock it out to install a new one would be greatly appreciated! Love the info from Crockett. I'm an engineer in the aviation field... I sprayed the frozen bolt with PB Blaster when I realized it didn't want to budge with the impact wrench, but when I put the breaker bar on it, it snapped almost immediately. I was having a little grinding between 1st and 2nd and was going to change the transmission fluid. When I got the skid plate off (trans held up with my floor jack), I realized the shifting problem may be due to the transmission sitting off to the starboard side due to the broken trans mount. I would like to put all 6 bolts back in, but if I can't get the broken bolt/nutplate out, I am ok with 5.... I can't seem to find a part number for a replacement bolt, and since most of them have some rust on them, I would like to replace all 6 bolts when I put it back together. Anyone know where to get the bolts?
Any suggestions would be greatly appreciated. My 1997 Suburban K1500 has 230,000 mile on it and I am proud to say I am the only mechanic that has ever worked on it. I don't know the history of my 1991 Renegade, but I'm eager to give her a little TLC and take her where she should be. OFF-ROAD!!!! Wheeeeee!
Doug, call Blaine from Black Magic Brakes (look up his phone number from his website). He is a vendor here and on several other Jeep forums. He carries a kit and can give advice whether his bolts are what you are looking to replace or if there's other options available.
I just replaced one of mine with a 1/2 x 20 grade 8 bolt with a flat washer. Seems to be fine. As you stated, I had 5 OE's in so not to worried. I have also seen a trans drop kit that gives you new bolts and spacers. May look into that. Usually used for lifted vehicles though.
