yxmj Posted July 29, 2013 Share Posted July 29, 2013 Hello all Newb question here. ( New to MJ’s Not Jeeps) Just picked up a cherry 1987 MJ (less that 60,000) original miles on it. 2WD….2.5….Ax5…. Here is the question……Trans was unattached….pulled back and strapped to cross member when I bought it. Put in a new slave and had the dreaded job of putting something back together that II did not take apart….. Re-attached everything……or so it seemed…..at the end of the install there is a bar about 18” Threaded at one end with a hole for a bolt on the other. Could not figure out where it would go so set it aside. When we drive over rough roads the trans bumps against the dog house….I first thought the tranny mount was busted but we dropped the cross member and checked and that is not the case …so I am thinking the bar is some sort of extra brace…..can anybody tell me if this is so and if so were it is installed?

jimoshel Posted July 29, 2013 Share Posted July 29, 2013 There is a steel rod, brace on the right side of the engine. One end fits through the lower, right hand hole in the bell housing and runs up and forward to the motor mount. That's it. The threaded end fits into the bellhousing. The other end is attached to the motor mount with a bolt. Link to comment Share on other sites More sharing options...
HOrnbrod Posted July 29, 2013 Share Posted July 29, 2013 Jim, why so many braces on the 2.5? They also have that little shock absorber brace on top too, right? Never had a 2.5; are they prone to vibes? Link to comment Share on other sites More sharing options...

Never had a 2.5; are they prone to vibes? I have wondered that myself. The shock thingy on the right front of the engine is a torque absorber. Only reason I can think of for it is the 2.5 mounts may not be hefty enough for the job. I have drove a XJ with both missing and never noticed any thing unusual in the handling. Highway only. No cross country. Link to comment Share on other sites More sharing options...
Geonovast Posted July 29, 2013 Share Posted July 29, 2013 Also another thing that was eliminated from the 2.5 in 91. I replaced the trans in my 91 2.5 twice and didn't have to deal with that either time. Link to comment Share on other sites More sharing options...
gogmorgo Posted August 3, 2013 Share Posted August 3, 2013 Could have been an over-protection against vibrations. Inline-fours simply don't balance without extra balancing shafts. Some are less vibey than others, but having no experience with the 2.5L, I can't really say how it does. I also don't know if it has balancing shafts or not, but I'd guess no. The GM Iron Duke doesn't. Link to comment Share on other sites More sharing options...
jimoshel Posted August 3, 2013 Share Posted August 3, 2013 No balancing shafts or anything. Just the flywheel. That's one of the reasons the pancake 4 is so popular. Two opposing cylinders cancel any vibration . Link to comment Share on other sites More sharing options...

So the point of this post was to say.........you have no knowledgeable input of the topic..... :thumbsup: good job Link to comment Share on other sites More sharing options...
jimoshel Posted August 3, 2013 Share Posted August 3, 2013 Sorry Don. Gotta disagree with you there. I was riding a Harley when i was 12 years old. A Beemer is the smoothest bike I ever been on but I'm a Harley guy. Link to comment Share on other sites More sharing options...

A Beemer is the smoothest bike I ever been on but I'm a Harley guy. Was doing some editing and I edited my post to oblivion. :dunno: Anyhow, that's why they make so many different bikes, autos, trucks, etc.; everyone has a different opinion and wants. IB a beemer guy. All's well. Link to comment Share on other sites More sharing options...
jimoshel Posted August 3, 2013 Share Posted August 3, 2013 I gotta talk about my first bike, a '42 Harley, It was designed especially for the Army, Marine Corp as a courier. Was 45 cubic inches, opposed cylinders, 4 speed tranny. Had a driveshaft. not a chain. I got it in 1947. Had to keep it at my uncles house. Mom absolutely said no to me having a motorcycle. Still had the leather scabbard on it for a Tommy gun. Tore the prairie up chasing jack rabbits on that thing. Rambling over. We now return to the previous thread. ;) Link to comment Share on other sites More sharing options...
HOrnbrod Posted August 3, 2013 Share Posted August 3, 2013 Yeah, That bike was a poor Harley copy of a BMW design, except w/o the reliability. Worth big bucks today, if there any left running. Link to comment Share on other sites More sharing options...
