Title: 1948 Cletac HG 42 rebuild, restore, reuse.
Post by: FordManMT2 on September 19, 2017, 09:37:15 PM
Hello Ladies and Gentleman.

This weekend I acquired a 48 Cletrac HG 42. Runs decent, steering is a little weak, and it does smoke. It has a loader on it (HORN i think) with some leaky hydraulics.

After I brought it home I drove it into the shop and pulled the cowl off. Pulled the plugs and at least one was fouled out, one more in bad shape, two looked great nice deep brown color , no matter ordered some more. But in the meantime I cleaned the plugs in it for tinkering.

I myself am a professional welder/fabricator, after seeing the loader on this I am slightly appalled. It has been hacked apart and welded back together countless times, which is probably why it hits me in the side of the head when I drive this thing. So one of my more pressing matters is to build a new loader before snow sticks.

The manifold has been repaired once, but cracked all the way through on the other side, so I may be fabricating a new one.

I did some digging and I cant find much solid info on 12V conversions. I know I need an alternator, but can I switch it to a ground negative system? Or will that mess something up with the magneto? I know Ill need new gauges ect. I'm just worried to do anything because of the magneto, so if someone can help me out that would be great.

Also does anyone have a link to brake band replacement? the guy I bought it from gave me some rebuild bands. I could hardly steer it enough to load it until I adjusted the linkages.

Anyways I will be sure to post pictures as I work though this old beast. Any help would be much appreciated!

-Dustin

Dustin,

New manifolds are available from a couple sources for these. Prices aren't bad either, so I wouldn't bother fabricating.

The magneto has no connection whatsoever to the electrical system, so changing to 12 volt or negative ground will have no bearing. There are some nice small 12 volt alternators out there that fit nicely. I'm sure you'll get some responses on these. Going from positive to negative  ground would just involve reversing the battery terminals and hooking up the new alternator. Reverse terminals on the ammeter. You'll have to change light bulbs when going to 12 volt. Starter should be fine.

Hope that helps,
Blake

is the ammeter connected to the magneto at all or is it just for showing that they system is charging? The gauges are all broken and there's no lights currently on the tractor. Which is part of the reason I want to do the conversion.

Amp meter is just tied to the charging

Thank you. I may or may not have a video up on my YouTube channel tonight.

But just incase I'll post an update,

#1, installed new spark plugs

#2, added some marvel mystery oil to crank case and fuel tank, added some seafoam to fuel as well. I noticed quite a bit of oil and carbon build up on cylinders 2-3. I'm not sure if they naturally run rich like that or if I have a bigger issue

#3 unbolted hydraulic pump, unbolted radiator so I could pull the jack shaft. The pump coupler was shot and causing the shaft to travel in a elliptical pattern. So I will take it into work and make a new coupler out of UHM plastic.

Next step is pull the loader off.

I'm not sure if it's the generator bearing going out, but occasionally the engine squeals. It doesn't sound like a belt to me which is concerning.

Engine oil pressure is between 20-25psi which is a good thing.

Welcome,

Did you look at the "Easy Alternator Conversion" thread stickied to the top of this section?

You can click on the link in my signature at the bottom of this post to get there too.

Hope that helps
