Just started this video. Suggest in the future you remove any plugs and soak cylinders with PB blaster or equiv. You do not want to damage rings. Giving in the best chance. Thx for vid.

There is a site where you can get almost any books on old CAT equipment

7J4075 -- 1940 maybe have green OD paint on the first layer.

Having over 50 years experience with D4s, if they ran the pony motor dry of fuel, it should run with fresh fuel.

[@uptheholler1501]

It doesn’t have any spark right now, I’ve cleaned the points, could be a bad condenser

[@TimBreslain]

I had 7J354, similar La Plante Choate blade

[@uptheholler1501]

That’s cool

[@RogerKastel]

Why would you turn engine backwards? Are trying to undue the bolt?

[@uptheholler1501]

You an clearly see I’m not on any bolt, I’m using the shaft for the hydraulic pump, and it doesn’t matter which way you turn the engine as long as you can get full rotation out of it.
It was easier to get access with a pipe wrench from the side I was on.

Push start that Ol girl.

[@uptheholler1501]

I just got done cleaning the carburetor, we’ll see what happens.

[@hfdzl]

If you get the serial #, I can give you a year.

7J4075

[@MrPandale-e1o]

Rd4 has 3 cylinders

[@uptheholler1501]

Yeah it’s a d4

[@uptheholler1501]

Didn’t realize till after I checked the serial number

[@saltysaltysaltsalt]

I do not think that's is an RD4

[@uptheholler1501]

It’s not, that’s what I was told by the owner, then I found the serial number and checked it, it’s a D4
