what to do a rebuild on my 320b cat excavator has a 3066 do liners have to be replaced to i am new to this.Starting to use oil plus a few leaks so figure its time 13000 HR.
These are Mitsubishi engines witch makes me think there was lots of parts available. Costex tractor parts ( ctp ) of Miami Florida offers affordable kits . Block does need to be machined not a big deal. Some machine shops will supply parts some won't. Might want to talk to you machine shop first. I'd drop head block and rods off. Your machine shop might assembly you a long block cost effective also.
Ok thank you Another question can you split the pump from the engine without taking the hyd. pump out.
Yes I put piece of pipe with a ratchet strap to hold pumps.
Thank you for the info.
