88mjmanche Posted August 12, 2009 Posted August 12, 2009 how hard is it to change a clutch i a 1988 comanche ive never done it but i have a whole shop full of tools but no lift :fs1: on a scale from 1-10
Geonovast Posted August 12, 2009 Posted August 12, 2009 I'd say about a 7, depending on if you've got some help and a level surface to work on. Transmission has to come out, and you're going to need to disconnect the clutch line, reattach, and bleed when you put the trans back in. It's going to be a little easier with a 2.5.
Eagle Posted August 12, 2009 Posted August 12, 2009 You didn't mention if your MJ is 2WD or 4WD (or else I missed it). Replacing the clutch is several orders of magnitude easier if you have a 2WD.
Oizarod115 Posted August 13, 2009 Posted August 13, 2009 you're going to need a few feet of extension, and a good jack to pull it out on.
87Warrior Posted August 19, 2009 Posted August 19, 2009 Make sure you get the funny clutch alignment tool that fits into the pilot bearing. I changed the clutch in my 90 YJ. Dropped the transmission and transfer case. Was a royal PAIN without the transmission attachment for the floor jack. I found it was easier to pull the motor out of my Rubi, with hoist and engine leveler, than to drop the transmission and transfer case in the YJ. Make sure you replace the pilot, throw out, and slave (if internal) while down there.
88mjmanche Posted August 21, 2009 Author Posted August 21, 2009 yea i got all that stuff and a friend whos do it before so we should be all good what else should i be careful for?
akamcbird Posted August 23, 2009 Posted August 23, 2009 what a pain in the a$$!!!!!! been under the truck for to many hours to mention! and that just got the thing separated!finish tomarow those top bolts spose to be torx! coulda told me if yes :rant: .....still fun to get dirty tho
Geonovast Posted August 23, 2009 Posted August 23, 2009 Yeah... those top two are torx. Don't put them back in! Take one to the hardware store and get some high grade hex head replacements, then chuck the originals.
akamcbird Posted August 23, 2009 Posted August 23, 2009 if i replace them ill never use these new sockets ever again....
Geonovast Posted August 23, 2009 Posted August 23, 2009 Sure you will, there's plenty of Torx stuff around. I don't know anybody who's put those stupid things back in...
Wildman Posted August 24, 2009 Posted August 24, 2009 I've reinstalled the top 2 male torx screws before :D I just consider them as a "anti-tamper" screw :brows: The worst clutch job I've done, the pilot shaft "welded" it's self into the pilot bearing :fs1: I had to use a come-along from the tranny to the rear axle to "pull" the tranny out :headpop: Talk about many hours under the truck, turning the tranny every which way, and prying on it with everything on hand :wall:
akamcbird Posted August 24, 2009 Posted August 24, 2009 AARRRRGGGG!!!!! finishd...finaly.. take it for a test drive and it works great..for about half a block, hear a pop and the engine dies and won't restart. starter turns without issue and everything looks fine... what happend? what did i f up? please don't tell me to drop it again.....
dasbulliwagen Posted August 24, 2009 Posted August 24, 2009 Check the crank position sensor and the wire going to it, maybe you pinched the wire, or it came undone.
Eagle Posted August 24, 2009 Posted August 24, 2009 Check the crank position sensor and the wire going to it, maybe you pinched the wire, or it came undone. Either that or something from the clutch or flywheel physically took out the CPS. When you reinstalled the bell housing, can we assume that you put the locating dowels back in so the bell housing is correctly and accurately aligned on the block? The clearance between the CPS and the teeth on the flywheel is only a few thousandths. If the bell housing isn't exactly where it should be, there may be an interference fit there.
akamcbird Posted August 24, 2009 Posted August 24, 2009 yes the housing is aligned and i will check the cps wen i get off work thanks.
akamcbird Posted August 25, 2009 Posted August 25, 2009 how come nobody said nuthin bout that cps wire before i pinched it and chewd it up with my flywheel?.... yesterday ida never taken on this project again. but today... after doing it 3 times... no worries
Wildman Posted August 26, 2009 Posted August 26, 2009 how come nobody said nuthin bout that cps wire before i pinched it and chewd it up with my flywheel?.... Because you said you had it all under control.........and we all went home early :D yesterday ida never taken on this project again. but today... after doing it 3 times... no worries Yes.......Experience, Experience, Experience.........Now that makes you a Pro :D I bet the next clutch job, you can do in your sleep :yes:
akamcbird Posted August 26, 2009 Posted August 26, 2009 I'm not sure i wasnt sleeping through the last runthrough
