Mitsubishi Minicab
I have a 1998 Mitsi minicab, 12 valve, U41T (2wd) with the 3G83 650cc engine. I have just done a partial rebuild, new piston rings, skimmed head, head gasket etc. I see that the oil pump/balancer can be set at different positions even when the engine is at top dead center with all timing marks correct due to the fact the oil pump/balancer shaft sprocket is geared. I have spun it many times with the engine apart and have no idea where it was before I took it apart.
-is the shaft for balancing the oil pump only.
-is the balancer part of it to balance the engine, if so I'm guessing it is important how it oriented with the engine at top dead center with all timing marks correct.
Anyone who has done this or has looked how it works/rotates will know exacly what I mean. For every 3 turns of the cam sprocket, the oil pump/balancer sprocket will turn exactly 5 times, and it can be oriented in 5 different positions with its own timing mark pointing at its own corresponding timing (TDC) mark.
Any help appreciated. Thanks.
