mjeff87 Posted September 29, 2008 Author Posted September 29, 2008 Made some good progress this weekend…I should have it running by this coming weekend if not sooner. Jerry came down and gave me a hand splicing the NSS wiring and helping me swap out tranny crossmembers. A note to anyone installing an AX15 in their rig if there isn’t one there to begin with……all the transfer case shift linkage parts except the shifter handle assembly are different (specific to the AX15 ONLY) as well as the #%*#@$ tranny crossmember, which is diveted out in the center where the mount goes. If you use any other crossmember the TC linkage will not line up and your catalytic converter will be kissing the floorboard. Found all that out the hard way, but two trips to the junkyard later all is well. Got the NSS wiring spliced, swapped the fuel lines, reinstalled the windshield washer reservoir, got the 2.5 coolant overflow bottle installed and happy with the wiring harness (eliminated the ballast resistor and have to relocate the EGR solenoid). Got the battery/alternator wiring all tied in and reinstalled the battery. Turned the key to check for fuel leaks and to test the starter circuit……starter works and engine spins but the battery needs to be charged. The fuel pressure regulator is puking fuel all over the place at the seam where the two pieces are crimped together. Will be installing a new one this week. Ended up stopping work on the engine and installed the trackbar brace, pulled the rubber cargo mat and reshot the floor with spray-on bedliner. I have a new cargo mat but I think I’m going to leave it out for now and see how loud it is. I can always pull the seats out and install it later. Couple pics: Spliced the NSS wiring (well, Jerry did…..:D) Image Not Found gas pedal is different between a 2.5 (left) and 4.0 (as well as the throttle cable) Image Not Found cover for the tranny hump is different (AX15 on R) Image Not Found RE trackbar brace installed (what a PITA!) Image Not Found fresh coat of bedliner on floorboards (you can see the repairs I made a couple years ago on the driverside……there was nothing there) Image Not Found
WahooSteeler Posted September 29, 2008 Posted September 29, 2008 Lookin good Jeff! LOL, after this you'll have to share the short list of parts on the truck that are actually original vs. replaced/upgraded/modded.
mjeff87 Posted September 30, 2008 Author Posted September 30, 2008 Still rockin' the stock steering wheel.....and glove compartment door, too :D Tossed the rear driveshaft up yesterday, just for s***s and giggles....it's about a foot too long. Gonna have to have it cut down, again :oops: Didn't try the front shaft, but I'm pretty sure I have one that will work. Jeff
mjeff87 Posted October 2, 2008 Author Posted October 2, 2008 got the fuel pressure regulator swapped, changed the front U-joint on a stock front AX15 driveshaft I got from Pat and installed it. Charging the battery, have to bleed the clutch yet and install the radiator, pipe up a new muffler and put the seats back in. Should be driveable on Saturday (FWD for now, until I can get a rear driveshaft cut down to fit). Jeff
project88mj Posted October 2, 2008 Posted October 2, 2008 that will work? i didnt think that th t-case could do that cane some one explain or give me a link to a post that does :huh???: :dunno:
mjeff87 Posted October 2, 2008 Author Posted October 2, 2008 I'm running a late model 231 TC that has the sealed output. Just put it in 4HI and you get FWD with no rear shaft..... Not planning on any roadtrips with it, just moving it in/out of the garage, and maybe up to the corner gas for a fillup. Once I measure for the rear shaft and drop it off at the shop, I should have it the next day. I'll probably do that next week (they aren't open on weekends). Jeff
mjeff87 Posted October 3, 2008 Author Posted October 3, 2008 couple random pics…… shot from underneath: Image Not Found new TC installed: Image Not Found shot of the AX15 crossmember, showing the divet in the center where the mount attaches: Image Not Found got the flange welded up on the new cat and got it installed: Image Not Found
HOrnbrod Posted October 5, 2008 Posted October 5, 2008 Congrats Jeff-man! Looks and sounds great! Were you peeing down your leg as I was when I first fired up my new stroker? Wish I had documented it as you have done so well. I hope you're slamming the brews down 'bout now - you deserve it mate. :cheers:
Wildman Posted October 5, 2008 Posted October 5, 2008 :eek: It's alive :eek: Got to be the greatest feeling when it fires up and purrs :D :thumbsup: I'll go stand back in the corner now :popcorn:
pingpong Posted October 5, 2008 Posted October 5, 2008 I feel so proud.. just about all his drivetrain came from my spare parts bin :eek: Nice Job Jeff.
Drahcir495 Posted October 5, 2008 Posted October 5, 2008 Fire in the hole............ :cheers: It sounds Great . Congrats on a job well done - Rich
JeepcoMJ Posted October 5, 2008 Posted October 5, 2008 great job jeff! man, she sounds beautiful. that's quite a truck you have. but is it just me, or did the oil pressure look low (unless you let it sit and idle for awhile...?) for initial start-up?
BLHTAZ Posted October 5, 2008 Posted October 5, 2008 Fire in the hole............ :cheers: It sounds Great . Congrats on a job well done - Rich It does sound good, but it looked to be running at a little over 1000 RPM in that quick shot of the tach you did. It should be down around 700. Keep up the good work... :D
mjeff87 Posted October 5, 2008 Author Posted October 5, 2008 Yeah, I've got about 75 psi on startup.....that was after it had been running for about 20 minutes. It stays at a constant 35-40 when hot, and blips when I hit the throttle. Might switch to 10W40. I've got a few little issues, such as the idle.....it is right around 1K. When it first starts up it revs to about 1800 then drops to a steady 1K....may swap the IAC, but I'm not sure I don't have a vaccuum port that isn't connected yet. I just booty-fabbed things to get it running....I'll fine tune it later on this week. Other than that, my fuel gauge is pegged (and I only have 1/4 tank in it). I think it's becuase I have a Renix-era cluster in it, and I swapped in a HO fuel pump assembly. Something else to figger out :D Thanks for all the compliments guys! :cheers: I had lots of help from alot of you on here, and I wanna say a big thank you to the CC community It wasn't the easiest thing I've ever done, but it was sure worth it. I took it out for a short spin earlier today and the power difference is night-and-day. Didn't want to push it with just the front shaft in it.....I'm picking up the rear (shortened) shaft tomorrow after work. Then we'll see what she can really do. Jeff
mjeff87 Posted October 5, 2008 Author Posted October 5, 2008 put a glasspack on it with a turndown tip :chillin: Jeff
WahooSteeler Posted October 6, 2008 Posted October 6, 2008 Heh heh, way to go Jeff, great job! Sounds great for sure. What a great day for you: perfect fall day to work on your MJ, get 'er fired up, watch the Stillers win another one! :cheers:
mjeff87 Posted October 6, 2008 Author Posted October 6, 2008 and Tony Stewart winning Talledega.......I hit the trifecta! :D I'm hurting a bit today though....probably gonna take it easy this week and not work too much on it. I've got a long weekend coming up this weekend, hope to get it all buttoned up and start cleaning out the storage unit so we can move my neighbor's junk in it. Jeff
mjeff87 Posted October 8, 2008 Author Posted October 8, 2008 got the rear shaft on it last night after work and took it for a good spin around the storage facility. I can spin the 33's from a dead stop :chillin: Jeff
pingpong Posted October 8, 2008 Posted October 8, 2008 Sweet.. You going to go on the Punkin Run.. Its only 23 bucks a night at the camp ground.. some light wheeling on site. :nuts:
tjbliley Posted October 9, 2008 Posted October 9, 2008 Sweet.. You going to go on the Punkin Run.. Its only 23 bucks a night at the camp ground.. some light wheeling on site. :nuts: Where? I think I missed something.
pingpong Posted October 9, 2008 Posted October 9, 2008 MPJAI is having a Punkin run up at Misty Mountain Camp ground in Crozet.. check out mpjai.com and look at the future trail rides and you will see it. They even got cool shirts made up, but you need to order them by friday
mjeff87 Posted October 9, 2008 Author Posted October 9, 2008 Forgot to post this earlier……pic of the difference between the 2.5 and the 4.0fuel pumps (2.5 one is the smaller one on the bottom). I was going to try and see if the 2.5 pump would have enough psi to fire but went ahead and swapped everything out beforehand. I wasn’t sure it was going to start to begin with, and didn’t want to add a variable to the equation if I had to troubleshoot. differences: Image Not Found because MJ fuel pump assemblies have a tendency to crack where the metal lines pass through the mounting plate, and they are universally unavailable anymore, I decided to add a bit of JB weld to the lines on the new assembly before putting it in as a safety measure: Image Not Found
Mitch Posted October 9, 2008 Posted October 9, 2008 does jbweld work well with gasoline? or will it get broke down?
