Do any of you have source to cat bulldozer D3C LGP III complete shop manual, any suggestion is highly appreciated, thx
There are two different Servivce Manuals for D3C Series III - SENR1245 and SENR5330. Which one of the two is the correct one for your machine depends on the Serial Number. Post the S/N and I can tell you which one you require. Both of them appear to be available on eBay.
That is the machine tag plate, should be a complete number of it,
This model was not designed to be sold world-wide, only in the Japan market. Obviously some found their way to other parts of Asia. As such it does not appear in the mainstream service system. The only 100% appropriate manuals for it will be in the Japanese language. However after a bit of checking in other resources, the most appropriate English language manual for your machine would be SENR5330.
