Hi all;
After completely and embarassingly blowing cam timing on two consecutive en=
gines i bought from Moss a so-called "vernier" adjustable cam timing sprock=
et made by Powertune. =C2=A0It consists of a hub and sprocket held in relat=
ive position to each other with 6 Allen head cap screws near the periphery =
of the sprocket. =C2=A0The cap screws have a fancy machined and anodized al=
uminum washer under them to spread the load. (See picture).
My question/concerns are:

Is this robust enough to hold position? =C2=A0Is the friction between hub a=
nd sprocket sufficient? =C2=A0
Do the aluminum "washers" hold up or do they creep over time, reducing the =
clamping load and allowing it to slip?
Does anyone have a suggestion for the torque spec on the 6 Allen headed cap=
 screws (no specs given with the sprocket) or the hub to cam (book says 24 =
- 26 ft lbs).
Should I assemble this Loctite between the hub and sprocket to keep it from=
 slipping?
Or should I send this back and get a more robust unit? =C2=A0If so, where c=
an I get a better one?

Thanks!

Phil Gott

 Phil,My two cents (no cash value ). I have used vernier sprockets on my TR=
3, my wife's TR6 and my Bugeye race cars, and haven't had any issues. I don=
't torque them to a specific number since mine are all aluminum, but I do L=
octite blue the screws. Have never had any slipping or wear issues. And the=
 ability to get the cam timing just right is awfully nice, especially on th=
e 3 as it's so critical.=C2=A0
Cheers,Jake

Hi Phil,
          Are those 6mm class 12.9 socket head cap screws?  If so, that's
very similar to the powertune venier sprockets for the 6 cylinder engines.
I've used them a few times without issues, although the Goodparts option
with 5/16 bolts is much more confidence inspiring on a race engine.

For the 6mm bolts, I use blue loctite 243, and torque them to about 11
ft-lbs.

Phil, I use one from Rimmer Bros (now part of Moss) that's all metal.

Here's the current TR version, made by Kent
https://rimmerbros.com/Item--i-145870URK

This is the one on the Spit, installed and running for a few years now. My
machine shop guy likes it.

 Yes torque the hub to the cam to spec, using proper shouldered bolts, & ci=
nch the screws up good w/a dab of blue loctite, they work fine.
