Double roller install

[Blizzard242]

Ok, so.. Installing a rollmaster double roller. It just doesn't seem like the top sprocket is goin on the cam shaft far enough. I have the balancer shaft gears off.. When I put the top sprocket on, even without the chain.. it just stops in the same position every time with nothing there that's obviously blocking it or running into it. There's about a quarter to half an inch of space left on the sprocket that looks like it should slide up to. Is it suppose to sit flush or have that amount of space? I'll take a picture when I go back out. If anyone has any pictures of a timing chain installed without the bolts I'd appreciate it cause I'm just a little worried I'm gonna mess somethin big up.

Is it lining up with the crank gear?

Re: Double roller install

Ah I forgot to take pictures.. But the crank gear can go on further than the camshaft gear. If I turn the camshaft sprocket around backwards it lines up with the crankshaft gear. Installed correctly though the camshaft sprocket isn't allowing the crankshaft sprocket to sit back as far as it's capable on the crankshaft. Which worries me that it's going to rub the oil pump cover. Is there suppose to be a very small lip on the camshaft that doesn't allow the sprocket to go back any further? Cause I have a very very small one I can barely feel with my finger nail.

This is becomming very frustrating because i was just sizing it up with the timing cover and that doesn't even want to sit flat, it wobbles a little. There is no obvious obstruction either, I'll try setting it on there tomorrow with the chain off just to eliminate possible problems.

I should just buy a new cam for this season too. I'm sure someone will want it when I get the one I originally intended for. I just can't now because stock heads clearance and all that.

I got a question for you what you use to plug the rear hole were the balancer shaft use to be?

Re: Double roller install

Didn't remove the balance shaft. Just disabled it by taking the gears out.

Re: Double roller install

I'll have pictures tomorrow.. wasn't feeling well enough to work on it today. I'll probably have it figured out by the time I come inside though. If not then **** on me and I'll have pretty pictures for you to look at.

Re: Double roller install

After getting it torqued down properly with my new cam bolt, it sits properly now. I didn't know the cam bolt took the sprocket so far back. All is well and going ahead as planned hah :)

Re: Double roller install

use double gasket or chain could scratch your oil pump

Re: Double roller install

No problems with rollmaster double roller fitting as far as I've heard.

What will running without the balance shaft do to the engine?

Re: Double roller install

nothing . gear is out.
balance shaft will have the oil hole plugged and wouldnt run. he will remove it later when he will have access to the rear door.

Re: Double roller install

No, what I am asking is GM installed the balance shaft for a reason, right? What long term issues will running the engine without it create?

Vibration?
Premature wear?
???

Re: Double roller install

just a lil more stress on motor mounts and an increased vibration in the lower RPMs. It's not a daily driver so I'm not worried about it.

Re: Double roller install

When in installed my double roller I had to sand/steel wool the inner ring of the cam sprocket to get it to slid on. crank sprocket went on fine i believe.
