'89 R3500 Crew Cab 2wd to 4wd conversion & beyond

Started out with 2wd TBI350 with SM465 to current 4wd with 454, 700r4, NP241
:waytogo:Thanks for the info.

I will be running 16" in the rear and 12" front. The fronts won't require much, but the rears will probably go through the floor.
 
Oops, I said 16" in my post, but I meant 15" on the Doetsch shocks.
 
I finally retired the 8yr-old Doetsch Tech shocks. Haven't had to do anything with them that entire time but the spherical ends are worn out and the mag-chloride has taken its toll on the finish of the bodies. Plus the crewcab is a lighter truck than the K5 I bought the shocks for and I have softer springs.

I pickup a couple Bilstein 7100 remote reservoir shocks, for the front only for now. I went with the heaviest off the shelf valving they have 320/80. Had a hell of a time figuring where to mount the reservoirs.

Just couldn't seem to get it where I was happy.

Won't have a good chance to really test them out until Blazer Bash.
I know it's busy in there but any good pics of the shock hoops and the shock hoop mounting? Also, who makes those hoops? Did you fab the cross bar or was part of the hoops?

I made it all. The hoops bolt in using holes from the 2wd stuff. This is the best post on the shock hoops http://coloradok5.com/forums/showthread.php?p=3281973

And the crossbar http://coloradok5.com/forums/showthread.php?p=3285840 But I ended up flipping it so the widest part is now the tallest part. Needed room to clear the fan switch in the t-stat housing.
 
When I fixed the broken lockout I noticed the wheel bearings on both sides were out of adjustment. I hadn't touched the wheel bearings in probably 6 or 7 years. Everything went fine on the driver side but I discovered this outer bearing on the passenger side.

This must have just recently happened because there was no collateral damage. In the last month or so I've made a couple wheelin' trips that involved several hundred miles of driving. Surely something more catastrophic would have happened if that bearing was broken at that time. There was no damage to the bearing race or the spindle. I still put in a new race along with the new bearing.

Glad I had decided to do the wheel bearings

YIKES!!!:eek1:
 
Now I have a new problem. About a month ago we made a wheeling trip. It's nearly 200 miles each way. After driving all the way there and running a trail, the truck started dying on me. We ended up putting in an ignition control module (ICM) Wade had with him. The truck drove fine all the way home and around here since. Until today that is.

Driving home from the shop, it died on me once about 15 minutes into the drive but restarted. About 10 more minutes down the road it died and wouldn't restart. I left it and walked home. Went back a couple hours later and it started fine and drove the last 2 blocks home.

I wanted to drive it back to the shop so I can check things out but it didn't make it 1 block before it died and wouldn't restart. We left it for a couple hours and it still won't restart.

I've only got 2 days before I leave for Blazer Bash so I think I'm going to try and swap out the distributor. Based on what I've heard from others that started having ICM troubles, I suspicion my distributor is no good. I suspect it's that or a wiring harness problem.

I did connect my ALDL and there were no error codes.
 
This sucks, but heres to hoping its something easy like the dizzy.
 
Pretty good chance that it will help fix it
I hope so. At least I can mark it off the suspect list if it doesn't help.

I also forgot to mention that after the wheelin' trip I put in a new AC Delco ICM so I can get Wade his spare ICM back. I did use all of the grease stuff when I installed it. I also cleaned all the gunk off the plate before installing the ICM.

I just hope swapping the distributor is "easy". :doah:

Need help, call me. I will shoot you my number.
 
Pull off a valve cover.

It makes it very easy.

As far as finding TDC? Motor could probably could use new valve cover gaskets anyway, although I'd only do the 1 at this point.

Thanks!


On a more positive note, I did a better mounting setup for the shock reservoirs. Need to trim off the excess clamps.

Yes, so you can watch for rockover. Seeing as you are just replacing the distributor though, you don't have to do that. Just line up the timing mark at zero degrees, and see where your rotor is pointing. Put it back there.

Okay, thanks for that advice. I wondered if I could just do it like that. I also thought about pulling the #1 plug to feel for the compression.
 
Watching rockover is easier to me than checking compression, but I am use to diesels.
