RD4 restoration help

Grayrat,

I see the intake is there. Missing is the magneto, carb, oil fill housing and governor. Will try and post a photo later.

I found several more parts in the brush around where the tractor was stuck?
looks like the oil fill the govenor frozen of course the carb also frozen, whats left of the MAG and an exhaust manifold. It's not apparent where the carb attaches to the intake everything else makes sense

I could use an air wrench to turn over the main but what is the startup sequence? I'm looking for manuals like service, operator and parts but Ebay is not much help so I'll post in wanted section could someone run through a quick startup procedure and what the large and small levers are for in the attached photo?

Sorry, I couldn't read the captions you put on the levers. Look at this, http://www.antiquecaterpillar.net/ACF_v2/showthread.php?t=4670 about a D2 of the same era as your tractor, so it's similar.

you'll have to block off the water passages to run without the pony motor, but it'll be a way to quickly make some progress on the machine as a whole instead of waiting on the whole pony motor to be finished.

is a discussion about checking out a "new" tractor. Last thing you want to do is rush to start something up and damage it because of water in the engine oil or a gear case. Some way of pressurizing the fuel tank may speed up the process of bleeding the fuel system when you don't have the pony motor on there. A piece of innnertube with the valve stem on it can be clamped over the tank opening and used to pressurize the system enough to bleed it after changing the filters/cleaning out the gunk etc.

Maybe a little encouragement or incentive is in order here😄 😄
This is what it should look like when you are done😉 😉
Belongs to Lou McMaster, a fine example of the model.

Whoops, forgot the picture

Thanks for all the help, keeps me from feeling i'm in over my head. I just found out the lower radiator housing is cracked by the drain plug. So now it's pull a part time and braze it up.

I got my books direct from Caterpillar...and I've also got an extra pony magneto and pony parts....

what shape is the mag in? email me [email protected] and I'm interested in the top end of your pony as you can tell from the photos. I found most of the original but it's been left on the ground for years and not sure how much is recoverable

grayrat,

You will find the books you need on ebay - operators instruction, parts & service (engine D4400 and tractor), it will just take a while for the right books to be listed at the right price. Reproduction service manuals are available, if you don't won't to wait for an original caterpillar serviceman's reference book.
