Torrington bearing & Long term durability?

Torrington bearing & Long term durability? - 07/26/11 10:21 PM

I'm looking at getting a Rollmaster timing set for my Six-Pack three bolt cam engine. The Rollmaster timing sets all come with the Torrington Bearing set-up in their three-bolt applications.

My only hesitation with the Torrington Bearing is long term durability in a mild street engine.

How often do these go bad if any?

Are they problematic at all?

Can I be confident it will last 100k plus miles in a mild street application?

Thanks in advance!

I hear that Amzoil oil eats-them-up .... so beware !

Thanks for that Doc, I can always count on your objective opinion

Anyone else care to weigh in?

...and we can always count-on-CHOO huffing-and-puffing that one certain oil !

#1 - From knowing a bit about Tor bearings in a converter and trans ... it can not be a sloppy-fit or you will hammer the bearings. #2 - I think on something like this ... it is a gimmick.

If they arent in compression all the time they work
fine... it needs to float some to keep it oiled...
never heard about Amoil eating them up and dont know
why it would

But P ....from what I know ... they work better with slight compression on them. The on-and-off can hammer them.

The Amzoil "dig" was just a

at CS ...

My gear drive has one behind the cam sprocket. I think its there so that when you install the required cam button you don't run the risk of seizing the sprocket to the block if you have too much preload. Personally I'd rather have some clearance on the cam button and not have the bearing there. If you're worried about it, go to a bearing supply and see if they have a similar size and thickness bronze thrust washer.

i don't see the need for a bearing between the camshaft and the block. there's no constant loading against each other. very seldom do you see a 40 year old block with any appreciable wear in that area.
we sell a few different brands of timing chains, including rollmaster, but we choose to install a better chain and billet top and bottom gears in the engines we build. (unless of course it's getting a belt drive)

Doc, I knew it was a 'dig". Without your "digs", moparts wouldn't feel like home.

MR P BODY,

So not much to be concerned about with a hydraulic flat-tappet? I always thought the Torrington bearing was basically for roller cam applications as roller cams don't have the tapered lobes to keep the cam from walking in unison with the cam button.

Just want to make sure all my bases are covered.

Interesting, I thought I've read that Rollmaster timing sets are about as good as it gets for timing chains?

Well, I'd certainly be interested in buying a better than Rollmaster unit if the price is right. Shoot me a price and model number so I can research it further if you would.

I'd be fine with a really good three-bolt timing set without the Torrington bearing.

Good info, Thanks!

rollmaster has a few different "series" of chain sets. some are better than others. their top of the line stuff is good. i didn't post the information or my opinion to try and sell parts. i was just trying to point out that i wasn't biased based on selling a competitors product, since we sell several brands, including rollmaster.
