Dan & Dumb dumb doggy (Scout) under the truck.

Spent all day at the shop with Dan today. He's actually liking this. Dan Likes it and Alex, the oldest likes it. Shelby's having a tough go because she's finding her lack of manly upper body strength holding her back.

So today we spent solving problems. How to get the &*$^(#@ power take off shaft out, or at least disconnected. How to get the exhaust pipe off. How to unbolt the radiator mount.. I finally broke down and went out and bought a couple air/impact wrenches, a long extension and a bottle of spray penetrating oil kinda' stuff. Aro-somehting, s'pose to be the best stuff possible.

After two days of feeble attempts and being nice, the exhaust pipe caved in ten seconds hitting the nuts with the impact wrench. Dan never seen anything like this before. Then the driveshaft for the power take off finally popped off when I used a large crescent wrench like a prying fork and a section of 2" pipe over the handle.

Radiator mount was giving troubles. I sent Dan down there with the new air ratchet. He couldn't get them to budge so I went after 'em with the impact gun. Got one out and managed to rip the welded in backing nut out on the other. Grrr... Did manage to get a wrench on the backing nut and had Dan run the impact gun for his first time. Danny now thinks these air wrenches are pretty cool things.

So were THIS close to pulling the motor and got stymied by the clutch and throttle linkages. How in the world do you disconnect these things? The manual talks about pulling the cotter pins. I can see 'em, but can't get at 'em. Does anyone have any advise on this?

Thanks!

OUTSTANDING FAMILY THREAD!!!!! Gives me hope with my little one yr old but with a yard full of MV's in various sizes, I think she will be right there with daddy.

If your pulling the engine and trans as a package. You need to take the linkages apart at the transmission (rt side cluster) and then the clutch and throttle linkage at the left side of the engine. All have cotterpins. Once you see them, use a good pair of "Alternative pliers" and pull them out any way you can.

Cotter pins are out on the left side. Throttle is disconnected. But the clutch? The pin won't budge. Any ideas on the clutch pin? We get the clutch then rear mount bolts and we can try pulling it. And see what else we forgot.

What do you mean about taking them apart at the right hand cluster? "You need to take the linkages apart at the transmission (rt side cluster)" I thought all the linkage stuff came along with the engine.

Oil drain plug, looks like a 12pt allen head? Is this standard? What to use to pull this out?

If you have any suggestions you can email

m37@leftcoast.biz

and we'll hear it come in at the shop where we're working.

Transfer and e-brake linkage bracket is attached to the trans case by 3 bolts, remove them and shift the lever assy toward the right, engine/trans is free to come out. The oil plug sounds like it may take a torx bit to remove it. Common at good tool outlets. That is not standard however, the original would require a 1/2" square drive bit to remove. Clutch linkage pin becomes worn, thus is hard to push out because of an out of round condition. You'll have to get ingenious with that one; it's an any which way you can removal procedure generally.

You are right, Allie is trying to drain the oil with the 1/2" drive. Scared to get it on herself.

Right side linkage is off, mounts are pulled and reattached.. There are two pins for the clutch linkage. The rear one is loose, but it hits the tranny when I try to slide it out. So we tried pushing in the clutch. That clears the tranny but locks in the pin.. Good lord!

pound it out with an air chisel?

Ok where were we?

I was whining about not being able to pull out this (*(*@E^%R%^ engine..
Image
Julie & Shelby assembing the engine stand. I'm hoping 1,000 lb stand will do?


Image
Allie & Dan fighting out the engine mounting bolts.. The girls have such nice small hands for getting at cotter pins.


Image
Lets see if it will come out? This is after we bought the air chisel for blasting out the clutch linkage pin. SHot the pin out, bounced off the gearbox and into the pan of used motor oil. Yuch!


Image
The three musketeers! These guys make this stuff go MUCH faster. The impact wrench does tend to rip the threads off/out of anything you use it on.


Image
It won't come out! Extreme frustration! We finally went home in total despair. And the radiator is hitting the arm on the cherry picker. Time to sleep on it.


Image
When you're completely stumped, bring someone along that can see things you can't. We left the kids at home and Julie & I came out this AM for a look. After some pulling and pushing. "What the heck is holding this?" Julie noticed something that seemed to be attaching the engine to the firewall. Sure enough, I'd forgotten the grounding strap! Dumb dumb dumb!


Image
SUCESS!! Julie says it felt like the truck gave birth after a long labor.

Julie just read this over my shoulder and is cracking up.

One upgrade we're going to need is new wiring. The old wires are just falling apart. Who was it that makes and sells wiring harnesses for these machines? I remember seeing their webpage but lost the link. Anyone have the link?

Thanks!

Jim Lee,

I ordered mine from them, it is a work of art and has excellent install instructions included with it.

Keep in mind that you can have it customized for turn signals, electric fuel pump etc.

Not much going on with the poor truck. Kids are buried at school, I'm busy building boats. I did manage to talk to the Vintage Wiring of Main people. Ordered a complete harness with blinkers etc. I can now toss the old crispy wiring along with its P.O. hacks. That'll be nice! Pretty soon I guess i'll be calling Midwest Military. Everyone points at them when I start asking about parts we need. I'm starting to put together a list..
