1g balance shaft - 11/12/2006 2:30:33 PM    racerx55 Posts: 1026 Score: 0 Joined: 11/9/2006 Status: offline the small belt drives the balance shaft correct? i thought that was the water pump at first glance, then i uncrossed my eyes & realized the water pump is driven by the serp. belt... BS belt broke, wedged between the tensioner and the timing belt, caused the timing belt to rip teeth off then break, the balance shaft turns kinda stiff, not like its locked up, just has some tension on it.i cant turn it by hand, i have to put a wrench on the nut.. does that seem normal or should it turn really free? i turned the oil pump with a drill and a socket, about 2500 RPM on the drill it came up to about 40-50Psi of oil pressure so i dont see any problem there, ive heard of removing the balance shaft whats all involved in that mess? could i just leave the belt off it and put it back together to get rid of the dead weight spinning? ill figure it out as i go i'm a really good mechanic on things i know, this is the first 1g DSM i think ive ever torn in to..i know a 420a like the back of my hand. just trying to learn a little about the 1g from someone that has been through them more Post #: 1

I'm not sure about these engines but I know on my Conquest (Starion was the Mitsu model) there were refered to as "Silent Shafts" not balance shafts as they don't balance the crank but instead they help the pistons. He's right about the removal though. There is a kit you will need and it will have a piece that will go in where the BS sat and cover the oil supply port. Definately pull the pump and take a look at it. You should be able to tell if it's bad or not. Also you'll likely want to replace the oil pan gasket as you'll want to pull the pan to clean the oil pickup tube screen and clean out the pan of metal shavings that may be present. It likely will be cheaper to just do the repairs vice getting a new engine. I spent $300 in parts and here's what I'm doing: Balance Shaft elimination, timing chain, all chain guides, cam and crank gears, new oil pump, oil pan gasket, timing cover gaskets, valve cover gaskets. It's feasible if you want to do the work yourself. Have a shop do it and you'll pay out the arse. _____________________________ (in reply to wb12859) Post #: 9
