I still have my cam gear and chain and they are new. Does anyone know if the crank gear is available separately?
Yes, JP bought out Rollmaster, as stated earlier the German IWIS chain is high quality.That's the same as Rollmaster. One bought the other out. I don't know which.
Rusty, let me know if you can’t get one, as luck would have it JP Engineering is only a couple of miles from my house so I’d be happy to get one direct for you and post it to the US if you’re happy to wait on shipping.I still have my cam gear and chain and they are new.

I think I’m correct in also highlighting that it’s not possible to run the factory oil slinger with a Rollmaster bottom gear as its prone to interference and damage - not really a big issue as many treat the slinger as an option anyway.
Cal no issues with the slinger on mine and bottom gear had no fitment issues considering tightness.Rusty, let me know if you can’t get one, as luck would have it JP Engineering is only a couple of miles from my house so I’d be happy to get one direct for you and post it to the US if you’re happy to wait on shipping.

Ok, so just to be sure, it’s a slant6 nine key way crank gear for a Rollmaster Chain Set that you need?I have no problem waiting. I've looked and I cannot find anyone here who sells the pieces separate.

It's not the greatest to "Figure out your cam timing prior to putting it on if possible and heat it up with a torch" because in most cases you need to figure out the timing using the actual gear. Even if you had a 'setup' gear, you wouldn't be sure it was the same as the 'real' gear.
It's interesting that you can buy a cheap OEM type timing set from a number of vendors and they all seem to fit pretty well...yet the Rollmasters seem to all be tight. You'd think they'd loosen them up a bit. Probably a symptom of using the metric system lol.
What do you use ?I have used a few Roll Master timing sets. I like them. Kim
Double roller. KimWhat do you use ?
Single or double.
I appreciate your input.
I HAVE 3 SINGLE ROLL PLASTIC GEAR SETUPS ON MY WALL they all have broken teeth maybe 10,000 hard miles on each once i switched to a steel gear never had a problem , plastic is good for lego , not something that gets lots of milesI've seen opinions over on Speed-talk that you only need a single but doubles sell.
Smokey Yunick used stock GM gear drives that came in HD trucks...Grumpy Jenkins used GM sets with the nylon top gear to get rid of bad harmonics in the valve train that killed valve springs.
Yunick also filmed the timing chains thru a clear plastic timing cover. He said the timimg chain at speed looked like a snake trying to escape from a small box....wiggled and whipped around
I'n a race motor long term wear isn't a factor so a single row would be fine.
Double rollers were never around back 40/50 years ago. I never stopped racing because double rollers had not been invented yet.... Can you imagine the first Indy 500 in 1911 being postponed because the SBC had not been invented?
My 71 Honda AN600 used a single row timing chain.....and there are still silent chains out there, still work great.Does anyone actually a single row timing chain?
