What to do....... - Page 2

They are designed to solve a problem with the stub shafts wearing the case to one side which we several examples of here. If they are assembled right, there is no more risk of it coming out that a stock one and actually less considering the rediculous amount of weight they remove that is off balance. There is a valid reason to use them and there has not been one failure when installed correctly.

I know what they're supposed to do, but being that it is not directly attached to the oil pump gear, it's not going to correct any axial load that might be caused by timing belt tension on the oil pump sprocket. It's attached to the idler gear which really has no axial load except for maybe thick oil at startup pushing the gears outward as it's pumped through the gears. I actually have a front cover with evidence of this type of wear, and it's from an engine with both balance shafts.

The main oil pump gear and shaft have oiling passages on the top and bottom of the gear, as well as to the shaft itself, so as long as there's clean oil in there and it's assembled properly, it should always be riding on a sheen of oil, and cause little to no wear.

I liked the concept on paper, til I actually looked at it a little closer.

The wear on the cases we have are off of ones that had the stub shaft in them. There is no way full balance shaft can wear the housing to cause what these have, the shaft would have to be bent.

I'm covering my ears, I really don't want to hear this

As I just finished adding up all the reciepts on my first engine build.

Thanks guys for all your input, and I will most likely be building it again. Like kevin said, "once a DSMer, Always a DSMer!"

Yeah, it sucks but it will be a good learning experience. Take a little break and regroup, then have at it again.

Don't worry Lucas, I never had one fail due to assembly errors. Blew a few up spraying and not backing timing off enough. 340 in the cuda died that way. (yes I was hitting the button when most of you girls where in diapers) I really don't think you will have any trouble, just ask if you have a question and have confidence in your work. you will be fine.

yea ask mike EVERY SINGLE QUESTION you have. He loves that. He just loves the fact that people like me call him for the simplest questions!

good luck on the rebuild again. Like Jet said, take a break and get at it later. That is the best way. Breaks after these sort of things are needed.

Just to let you know, I had the same thing happen to a local kid who rebuilt his motor. He had the eliminator kit and we forgot to locktite the stub shaft. Lost oil pressure after 15 min. of driving. Found the stub shaft sitting in the pan. Destroyed the pump. Fortunately, after about 3 hours and a spare oil pump later, car was fine. Lesson learned. Bad thing is, he forgot to tighten the drain plug on the tranny and it ran out of fluid. I found the loose plug, tightened it and told him to buy some fluid. He never did. 3 days laters, it locked up on him. Brand new motor with about 250 miles on it, shot tranny. Sitting.......

That just brings about another point that should be mentioned. We all get in a rush to get something done from time to time, but it is almost always a mistake. Simple things get missed (power steering pump not bolted on) and shortcuts get tempting. It is never worth it, trust me. Always take the time to do it right, if you don't have what you need, wait till you do and if you don't know how to do something, wait till you have a definative answer. It never pays to rush things. Thats why I build most of my engines at night, no phone ringing or people to drop in and distract me. You need to be focused on the job at hand the entire time.
