Pulled the timing cover today. Was very surprised to see multiple timing chains on a 4 cyl motor. What is this thing! ?!

@Brad. I'm a decent mechanic. Just new to these trucks and motors. Mechanically inclined but not knowledgable I guess is the best way to describe it.

Shortly after posting those pictures I began disassembling the timing chain and realized that front chain is wrapped around the balance shafts. I remember reading about them, I guess it makes sense that they'd be timed with the motor.
What I'm wondering is how to re-time them during reassembly. I don't see any tdc marks or anything like I normally do on a crank pulley or cam sprocket.

I'm fairly sure based on those pictures posted on the front page of this thread by Brad (thank you by the way) that this is definitely the g54b motor, the 2.6. Sucks and means I've gotta return some parts I bought. I'm wondering if these trucks were built any differently to accommodate either the 2.0 or the 2.6? Am I going to have any problems with parts or performance having a motor that wasn't stock?

There are videos online in Youtube to help also. Just make a search in spare time. I hate to just call you Shit for a short name, seems awfully wrong. Anyway, if your taking apart, Put everything separate and numbered to it's proper home. Keep the place clean you know the routine. These are basic motors and youll do fine. 2.6 is ok, at one time it was the biggest 4 cylinder in production. You'll see identification on the block, like G54B, on the passenger side. 2.6 motors just don't like overheating is all. Hope you have a manual also. Follow it. Document and just relax, if it don't go back together, just think of the money in parts you'll have when you sell them. Probably put a new clutch in also huh? Wonder what else you will find that you didn't think you'd need...it will come.


Pull the motor out also. Stop bending over and make it easy on yourself. Get an engine stand

ouch... The engine codes can be confusing for noobs who do not speak mitsugibberish. SFB will get the hang of the lingo eventually

mitsugibberish: lol I like that

be glad you have the 2.6 - it has a lot more support for upgrades than the g63b 2.0. In the manual section there is books on how to time the silent shafts with the rest of the motor - its not that tough with the motor out of the truck, but it can be done it the truck with the timing cover off.
