Rabbit 2,
Don't feel bad, Cat hardly mentions the engine model in any of their literature, they just expect you to know......somehow😕 😕
CCjersey and Old Magnet, thank you both for the info. I've only owned this cat for about three weeks and you'll have already taught me a lot about it. You'll are "Top Drawer" in my book. Thanks again
Rabbit2,
The above book covers all Cat diesels upto the time of publication, it is Cat Form No 5060, mine is 5060B printed 12-47, the B is just to identify the edition.
I do not know if these are available as a reprint.
Cheers,
Eddie B.
