I tear aftermarket mounts lots. The OEM ones from the dealer seem stronger.... They make 'bullet proof' mounts, but they cost a pretty penny.

Thanks for the help anyway Mike, "torque hook" makes since now. Maybe motors roll opposite in Canada. :-) JimG > The passenger side won't fit hook up... hits the oil filter.

This doesn't apply to the v8, because I went to the dealer and they showed me the manual with both hooks up top. Unless the dealer is wrong?

Unless the dealer is wrong? The hooks have to be in the direction to hold the torque if you off road or you 'will' tear the rubber off fast. Just street driving will likely be fine, maybe? They must alternate with the passenger side hook up. Jim needs the right oil filter in his Jeep. The Dealer's book has a mis print. There is a bar across the bottom of the engine to hold it in when the mounts break. The mount hooks are for torque only. Really. Been there, the passenger side mount lasted 2 weeks when I put it in hook down to 'catch' the engine if the mount broke again because with the hook up and broke, my short filter got punched out by the mount when the engine dropped. I was wrong. The Haynes Manual shows it right. There is serious torque on them off roading. My new one has a badly bent hook already from the torque it sees. I explode hubs and stuff too so I guess I off road kinda hard but still.

[quoted text clipped - 16 lines] > > 99XJ Sport > > Remove the xxx to reply! When the motor rolls to the passenger side at acceleration, it seems to me the hook need to be down on the passenger side to catch that roll. This is the way I have them: (drivers side) frame|_motor_| frame (passenger side) JimG > The hooks have to be in the direction to hold the torque if you off road > or you 'will' tear the rubber off fast.

I know it's confusing as sh.t, I had to double check in the day totally sober to make sure, you had me wondering even. LOL! The engine rolls toward the passenger side. This means that side moves down. The hook's loop is at the top on the engine side of the rubber mount to catch it from moving down too far. The hook 'pin' that catches it is on the frame side pointing up. Same deal on drivers side. The engine will lift up on that side so the hook loop is on the bottom engine side to stop it. As mentioned I tried it with both down and tore the passenger side one right away so the engine lifted up in reverse. I just looked in daytime and 'both' of my 'loops' are bent pretty bad and I am already starting to crack the rubber on that passenger one. My Haynes manual also shows the mounts this way for the 6, the 8 and the 4 although the manual is wrong on the drawing. The drawing shows the hook loops on the frame side when in fact they fit on the engine side. It shows them point the right direction, just a mirror of what they are really. Now if 'your' mounts have the hook loops on the frame side then they go opposite what I have been saying. They still must alternate one up one down though.

Are you saying to install them like this: Passenger side: http://members.cox.net/85cj7/ng/psidemount.jpg Drivers side: http://members.cox.net/85cj7/ng/dsidemount.jpg My haynes manual shows a similar set up to this, but it has an additional bracket that the "hook" goes into between the frame mount and the rubber pad. Signature_____________________ HomeBrewer 85CJ7 (in Progress) http://85cj7.blogspot.com/ 99XJ Sport Remove the xxx to reply! Well, that is really interesting..... I could be way off base here, but are you 'sure' those aren't the 'frame' part of the mounts you have bolted to the engine? If your mounts weren't backwards it would be right. On all the ones I have seen and pulled, the square 'loop' part of the mount is the part with the two bolts like yours and the pin side only has one bolt, But, the one bolt side is on the frame mount, not the engine mount. If indeed your metal mounts are right for that setup, then the rubber mounts need to be flipped upside down. You need the square hole loop to grab the bar pin when the engine twists. Naw, you have the same mounts as my 258 and that big curved piece is supposed to be on the frame not the engine, I just went and looked. Even the haynes shows the big clunker parts on the frame side and the smaller ones on the engine.

I forgot to mention: http://members.cox.net/85cj7/ng/360mount2.jpg The yellow line in this pic represents what a 258 block side mount looks like...v8s are bigger.

The v8 pads have two bolts on both sides...the only difference being the bolts are in line on the frame side and diagional on the block side. I'm getting more confused by the minute. Signature_____________________ HomeBrewer 85CJ7 (in Progress) http://85cj7.blogspot.com/ 99XJ Sport Remove the xxx to reply! I would have to go look at a V8 to know for sure so let's figure you have it right for metal part positioning. (don't think so, but hey if it fits who am I to argue) The rubber mount has two metal plates. One plate has a bend and square hole in it. The other side metal plate has a bar 'pin' on it. There is rubber glued between these. When the engine twists under torque, the rubber mount moves until that square hole comes up tight on the bar pin. This stops it from moving farther and tearing apart. On the 258's the hole is on the engine side of the mount, so when the passenger mount twists down, the loop on the engine side grabs the pin on the frame side stopping any more movement. This setup needs the mount to have the loop and pin at the top on the passenger side. On your setup, you have the mounts reversed from the 258 setup. You have the loop on the frame side and the bar pin on the engine side. This means you need the passenger side loop and pin to be at the bottom to catch it. As the engine twists down, the pin on the engine side goes down so the loop on the frame side needs to be at the bottom to catch it. Reverse that for the drivers side. Hope that makes sense... ;-) Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's > > On all the ones I have seen and pulled, the square 'loop' part of the > > mount is the part with the two bolts like yours and the pin side only [quoted text clipped - 12 lines] > 99XJ Sport > Remove the xxx to reply! Quit your braggin'! ;-) Thanks, those are the only pictures I've found that show where to look for AMC engine size. Real Jeep engines use a left and right mounts.

Mike, After laying under my Jeep for awhile, I now see your point. Now the oil filter, I have always used a PH25 which is what the Fram catalog calls for. I also notice an adjustment slot for the mount on the frame piece, passenger side. How is this adjustment set? It could make room for the filter, not sure. Thanks for beating it into my thick head! I hope you didn't hurt your hammer. ;-) JimG "Mike Romain" wrote in message ... > Think again..... > [quoted text clipped - 28 lines] > > Mike LOL! It was fun... ;-) The thread isn't over yet..... I know that two filters can fit on. Mine has a short small diameter filter. Maybe look up a different year. The best I can figure for that slot was to make up for any differences in brands of rubber mounts. If one was thicker the hole would move a bit. Just a guess. The filter clearance is set on the engine side. Mike > Mike, > [quoted text clipped - 43 lines] > > > > Mike > After laying under my Jeep for awhile, I now see your point.

Any good parts store clerk should tell you that there is a short filter and a long filter - always get the short one. > I also notice an adjustment slot for the mount on the frame piece, > passenger > side.

When dropping the motor you only have to align the bolts to the slots and not get the bolts through small holes. There not adjustments, the motor will always sit at the bottom of the slots.
