Any spare time I've had over the past three weekends has been working on getting this old girl running. As many would know, these old Cats have a 600cc 2 cylinder boxer petrol starting engine to start the diesel main engine. I had to rebuild the magneto and clean the carb out before I could get it to run and then had several adjustments to make to the engagement pinion before I could get the main diesel to start. Finally, on Saturday I got everything right and the main diesel made smoke - the first time in many years. Very very satisfying! The 87-year-old owner (on whose estate I cut wood) was absolutely thrilled. And for a machine built in 1940, I have to say the quality and engineering is superb - American engineering at its finest.

Very cool. I really like old crawlers.

I'm guessing you already knew this, but you have to spin the main engine with the fuel shut off til it builds some heat. Theres a guage at the front there that is supposed to let you know when its ready for fuel.
Those are some tough old girls!
They make more power when lugging than when revving high. More smoke=more power.
Nice job getting it going!

Yes, old Cat's are a bit of an obsession with me. The problem was that the pinion would disengage before the diesel even had fuel so I couldn't crank the diesel long enough to generate any heat and I had to eventually hold up on the engagement lever with one hand while trying to operate the fuel shutoff on the diesel with the other to get it started. I have since adjusted the pinion catches so it only disengages once the diesel starts - and absolute mission as the only access is through a tiny hatch on the clutch bell housing sort of half under the dash. had to withdraw a couple of cotter pins, adjust the tension on the spring on the catches, and then replace the cotter pins - and I did this three times in stages to get the adjustment exactly right.

The ol pilot motor had to turn her over quite a bit to get it to fire again enough to stay running eh?

I grew up around one like this. When I was little id set on dads lap and steer. I loved that crawler and I'll get one eventually.

Very cool Steve! I hope you find one! I've recently brought my own CAT D2 and I hope to go and collect it next week - 11 hours drive though. It's a 1950 D2 5U only done 3940hrs from new. All original and untouched - been in one family since new.

my uncle has one of them
it has a motor from a farmall h in it now after the other got wore out and blew up
It was common around here for the muck farmers to graft Allis Chalmers WD 45 tractor front halves on to double the power to pull a 4 row planter vs two. The Clark transaxle in them was up to the task. Same unit in Case 310 dozers I understand.

Yep, the CAT operator's book asks for the operator to turn the main diesel over under compression 'for a few minutes' before giving it fuel. If done right the diesel should start immediately - no glow plugs you see, and as the diesel is indirect injection they doesn't start that easy. The pilot engine shares the water jacket with the diesel and the exhaust is jacketed around the intake of the diesel - all to aid in heating it up for starting. Very clever engineering as you are able to crank the diesel indefinitely before starting making sure oil pressure is up and it's warm before giving it any load. Probably why they are known to last so long and do massive hours.

Nothing wrong with indirect injection as long as the heads have enough cooling :cool:

Some ive seen actually have guages or a type of guage on the side near the pinion lever to let you know when you have enough oil pressure and heat to start.

Niece's neighbor sent a very low hour 69 ford 2000
Backwards off a cliff
It landed way below this fence
It drops about 20ft

This is very steep
The brushhog caught a stump and spun it around.IMG_20210620_162423.jpg

He didn't get a scratch
Even though he is the only person I've ever seen wear a seatbelt on a tractor.
It took a John Deere 450
To pull it out
The Ford kept trying to turn over on it's side it's so steep.

Duke took a header out of the Kawasaki mule
About 20mph
He saw a red squirrel and jumped for it
And rolled down the road.

These early ones have only three gauges total, fuel pressure (you can see this on the fuel filter tower just in front of the injection pump), oil pressure, and water temp, the last two are on the dash to the right of the pony flywheel. You know the best way to know if it's warm enough to start? Hold your hand on the block just behind the engagement levers.
