Cat 933 info and advise

[chrismill]

Hello everyone, was wondering if I could get some input on this track loader. I need to find a machine to clear a a few acres of farm land. I dont have much to spend was thinking of trying to get this loader up and running but not sure if it would be worth it. The machine is for sale right down the road and asked the owner about it. He said that the machine ran fine until the last time it ran about 8 years ago. Other than it looking old and somewhat rusty it doesnt seem unsalvageable but my knowledge on something like this is very limited.
Was wondering if you guys could give me any advise on what to look for or if I should just stay away from this thing. I think its a late 60's? model not sure where to find a serial # the owner is asking 3500.00

first check out if the engine turns over and is not stuck. The rails don't look too bad, and the idlers are back from the front of the frame. Check the track bushings to see how worn they are and if they have been turned. Take a pry bar and see how much play is in the loader frame pins. If all that seems good then try to get it started and look for exhaust smoke and blowby. Then you can try and move it to see if the clutches are free and if the tracks are froze.
Then you can make an offer on the knowledge of what needs to be fixed.

This machine is a 933 serie 42a and should have a d320 or a late d311
motor in and its not a bad price.

Thanks guys, I'm going to give it a closer look this week and see if I can get it started and moving. The owner also has a jd450 for sale of about the same age-late 60's early 70's for 4000.00 undercarraige looks very good, but says the left hand steering clutch is bad/frozen. Anyone know how much something like that cost to fix? Or which machine is better? Thanks again-

That machine has the side panels that enclose the motor. It also appears to have had the rear ripper at some time in the past. Does he still have it laying around? So far, it looks like a nice machine, but don't they all? See if it starts. Is it a pony or direct electric starter? By the way, be careful of the poison ivy reaching up alongside the engine cover.

Im not sure about the ripper bar attachment. I'll have to ask about it this guys yard is filled with old equipment, there a real big old allis chalmers dozer in the back more overgrown than this one. Lots of neat old stuff and the old guy that owns the property told me everythings for sale. Anyway, I'm not sure about the pony motor where is it and what should it look like? Were the sides of the engine usually not covered? .I'm gonna try to get this thing running maybe by next weekend. Thanks for the help-chris I added some pics-

be sure to check that left side recoil spring closely--it may be cracked in a couple of places---the pony motor sits inside the engine covers and engages the flywheel of the diesel to start it.---look for spark plugs and wires. I think you really need a friend familiar with dozers to go look at it and advise you!

Not very familiar with the 933's but I see an absence of a pony exhaust out of the hood.
Hole is there, but no pipe. I would venture a guess that this is a direct start machine/no pony motor.

Hi Team,
I am fairly sure that by the exhaust pipe size that is a 933G (starting S/No 42A 06164) with the D320T engine and if I recall all the ones we sold at The Dealer were Direct Electric Start machines. As TractorDon points out there is no pony exhaust or petrol/gas tank filler tube/cap in view either. The battery box is under the seat from memory, and may have been 4 x 6 volt batts. = 24 volts.
Twas a long time ago now.
CXheers,

I agree, that appears to be a 42A model with D320T. In spite of the common reference to the D320T starting at sr # 6164 the parts book actually shows the engine starting at #5918 - up. At this sr # direct electric start was standard but the side winder "buzz bomb" pony was still offered as an attachment. If it has the pony, the only thing visible outside the sheet metal would be the pony gas tank filler cap which I can see in the pictures as missing.
