What have you done to your CUCV today/lately - Part 2

RobM36A2 · Mar 18, 2017

Update on the shifting issue:
Replaced vacuum lines with rubber fuel hoses, as the parts store did not have simple small rubber lines.
I did need to shave the lines down to fit on the regulator, but it was all air tight.
Also, I used clamps to make air tight seals on the plastic connectors.

Testdrive went good, very smooth shifting, afterwards on my trip for lunch, shifting got harder and later again.
Maybe a small vacuum leak. Going to retighten the clamps and put some silicone sealant on the connectors just to be sure.

@Rutjes: I am near Eindhoven. You sure you got a M1028 and not the more common M1008?

It is a M1028. I bought it thinking it was an M1008 until I saw the data plate in the door which was a nice surprise. It could off-course be a replacement door but max weight on license card is 4267 kg (M1008 would be about 3080 kg). VIN also suggest M1028 (1GCHD...) and it has a NP205 transfer case.

I found 99.999999% of parts store people don't realize what they have behind the desk-windshield wiper hose is the same as the rubber vacuum hose- it is cut to length as it normally comes in a 25 or 50ft roll.

But at least it seems to be vacuum related, and not a bigger issue.

M1008 would be around 3500 as car, and obviously more now it is registered as a truck. Mine is now 4263kg max weight.. same truck, 4kg difference..
Try jacking up the front axle, lock the hubs and spin 1 wheel. there should be a limited slip diff in there. (result is 2 wheels spinning in the same direction)
What is your tow rating, according to the RDW? Mine 2722kg.

Well, let's hope so, this was the most easy fix and needed to be done.

The only thing I did to my M1009 today is pull the studded snow tires off and put the BFG ATs back on.

I also finished making the back-up lights for my Grand Cherokee. The visibility out the back is really bad, and I wanted some aux lights. I did not want to hack up my factory wiring harness or run wires for a switch. My solution is to use the 7-pin trailer plug. It has a good 12v source, ground, and a pin that gets 12v when the shift lever is put in R to trigger a relay.

I dremeled the mounting tab and corners off a relay to make it fit inside the trailer plug. It's a tight squeeze but now I have completely portable aux lights on the back of my jeep- and a step to boot!

Exactly 2722kg tow rating as well. (I have a 4000kg Rockinger hitch (vangmuil) laying around that I want to put on it. Might try and get tow rating adjusted to that). Not sure if I get the chance to lift it up soon, any other way to tell if it has a slip diff in there?

Btw., I sometimes use it to tow trailers from my work. Those are rated at 3500kg but I have weighed one once, it was 7180kg. I estimate that I pulled at least 6000kg based on the load at the time and the truck had absolutely no problems with it. No highway towing sofar tho... Wouldn't even dare to with the current 40mm pintle hitch I put on temporarily instead of the 50mm nato pintle.

RobM36A2 · Mar 23, 2017

Did a little chore for my mom, went to get a sofabed for her. The bed of my Chevy was big enough for the little thing.
Still shifting late, but did not have the opportunity to seal the vacuum tubes. Maybe this saturday, or go to the parts store for wiper fluid tubes, as suggested a few posts back..
And noticed the glowcard is going bad or having bad contact, because it made some weird noises..
Oh well, it's an old truck, figures some things break now and then.

The Rockinger hitch, good luck with that, RDW will say some difficult things like install airbrake system.
And the pintle is "unknown" according to them. So no tow rating on the pintle, only the normal hitch.
There is another way to test is there is a limited slip diff in there, but not so good for the drivetrain, just lock the hubs, put it in 4x4 and try to make a turn :mrgreen:

I did some towing with mine, The carnaval parade, but also hauled some cars on a trailer.
Towed a GMC CCKW for a few miles, no problem getting it going, the stopping part is another story.
Also I got a M101 with shelter on it, that one I tow on the pintle to the UK. You can see that in my avatar.

Assel · Mar 25, 2017

took the CUCV for a final spin today....tomorrow I´m going to take the license plates off :shrugs:

(temporarily, dont worry, my dad just bought a car and now my M1009 cant be in his insurance as placeholder anymore

so I have to get an own ...kinda tricky & expensive in germany so I have to figure out how that works first before I can drive the ole chevy again.)

Good luck with that, Assel. [thumbzup]

I drove mine again yesterday. Big block did good as always pulled the RZR and trailer fine

Gerald Masso · Mar 27, 2017

Morning,
I am very interested in converting my cucv over to 12 volts... Could you tell me what has to be done...

I'm pretty sure there might be one (or more) stand-alone threads here that address that. Did you try a search yet?

computer54 · Mar 27, 2017

is this one gas or diasel

RobM36A2 · Mar 27, 2017

Pulled the glowcard, as it lets the relay chatter after starting.
So now searching for the most simple way to bypass it, because without glowing, my truck will not start.

Also used some silicone putty to close all the possible places where the vacuum tubes can possibly leak.
Now to let it dry and go for a testdrive when time permits.

Always fun with the old stuff.

MarcusOReallyus · Mar 28, 2017

The card controller works fine. If yours is not, get a new one. If you insist on breaking a good system, there's a sticky on exactly how to do it.

I had the same thing happen to me. Thought I had a 1008, found I had a 1028. Check your springs to be sure.

Just added 2 jerry can holders in the bed. 10 more gallons to make it through a weekend

Redid the headliner in my cucv clone suburban. Used marine marpat digital camouflage material. I think it turned pretty darn good if I must say so myself.

A headliner is luxury...
Your headliner is better than that.

That looks real good.

How did you stretch that material; are there fitted masonite panels or something that you glue it to?
