Hello, new guy here. I just bought a AC7g, I got a large service manual but no hydraulic diagram for the shovel unit. Also has a ripper. Anyone here have a diagram they'd be willing to share? Thanks, Corey in KC>

Hey, thanks for the tip. Yes, having the whole manual is well worth 30 buck. BTW, can you tell me what modern diesel oil to run in the engine for summer/winter? Regards, Corey

Well, I got the manual for the shovel system, however, it's for the B model. A completely different animal. Anyone have an early HD7G hydraulic manual to sell. And there's nothiing on ebay right now.

Rotella 15 /40 year round unless your running in sub zero a lot . you will need heaters anyway to get it running that low and need to get it warm before using .
