is it a good idea to eliminate the balance shaft on a stock motor? im about to do my timing belt and figured why im in there i could take care of it. anyone else do this on a stock block? what are the advantages and disadvantages of doing this

 

I'd also like to know this.

 

Advantage, less rotational weight, never have to worry about the B belt breaking and getting caught up in the A belt.
As far as disadvantages.. I don't know the answer.

 

Only disadvantage I can see would be having to pay for whole engine to be taken out just to do this.

 

I've never done one, but I bet it could be done by unbolting mounts and dropping one side down a bit.

 

Disadvantages:
- More vibration is felt but not made.
- Some bolts will start to back out. Ex: Oil filter and Alternator Bolts
- Oil pressure is kick up. This isn't bad but it puts a lot of oil in the head and the oil can't drain fast enough.. Solution is Kiggly's HLA Kiggly HLA

Beside that… I can’t really think of anything off the top of my head. Besides it's a PITA to install!!

 

Yeah, the hardest part would probably be getting the block off bearings installed while the engine is in the car. But again, I have never done one myself. I'm looking into the AMS kit.

 

You will need to rotate the bearing 180 degrees for the eliminated shaft to block the oil passage. I'm not sure if this can be accomplished with the engine still in the car. It really simplifies a timing belt installation with the pulley for the counterbalance shaft eliminated.

 

oh wow, i thought it was an easy install considering its like 4 parts in the kit. ill just keep mine. haha

 

Im def considering this as Im about to build my spare engine. are the gains worth the vibration??? is my only worry.

 

Also curious

 

Yes it can be done with the engine in the car. Myself and a couple of friends did it to mine. IT IS A HUGE PITA, but possible. We removed oil pan, and front cover assy. Took proper sized impact socket with adapt. and one good shot knocked out the bearings. Putting in takes a very steady hand, and good aim...Over all worth it in the long run just to avoide breaking the B-belt and trashing the engine.

 

i have the motor out right now and getting ready to install Gates timing belt and balance shaft belt.

now i'm thinking about going with AMS Race Balance shaft eliminator, but i'm worry that the stock ECU wont like the additional vibration. i don't want put it in and find out that i have to go stand alone ecu later.

 

I wouldn't even run a balance shaft eliminator unless you have a built/balanced engine....

 

not a built engine but the car will be on track more than street.
