That's an early model "F" before the forward/reverse lever was added. Engine is the D311H, not the same as the earlier D311.

I got my own picture of the serial tag. Does this make a difference?
42A671 no 0 before the 6

No, should be marked 933 Traxcavator series F.

those stickers are gone or hard to make out. One of them I believe says just 933 but no letter after it that I can see. I am just trying to positively pin it down so I am looking for the right operator manual and parts manuals

 

[Old Magnet]

Correction!!!!
The 933F became the "G" model with the D320T engine at s/n 42A5918 per Parts Manual.

Any info/break-down on this serial# 38F8066?
...would this machine have a D318 or a D333?
Thanks!

Second guessing serial # - Could be 38F3066??

 

[John C.]

Tag says that is for the hydraulic system. I've never had any luck trying to chase those numbers back to the machine but maybe the Cat guys here can make it work.

Look on the side of the engine block right below the head for a serial number plate.
If engine is original will be same as tractor serial.

Did some more looking more likely a 3306 will have a seperate serial than tractors.
