Timing gears

[DIV1RACER-2]

Several weeks ago i broke a timing gear & bent several valves , I was in process of doing a new set of heads at the time.I don't want this to happen again ! My question is who makes a timing set up that can take some pretty hefty spring pressure & 7000 rpm ??


I'm reluctent to put another cast gear & link chain in again & i don't like the roller setups i have seen .

Any help out there ??? :help

All I have ever heard of are the Pete Jackson gear drive or the Cloyes true roller set. In the back of my mind there seems to be info on a timing set that is made in Sweden . I run a Cloyes true roller timing set in my 09 but so far the most spring pressure I have ran is 320 lbs open at maybe 5800 rpm, I don't think that qualifies as serious! I would think the Pete Jackson gear drive would take some serious pounding. :scratch

I ordered a Cloyes set ( 9-3101) from summit a few weeks ago for the new motor.
They look like they are billet sprockets.
The set in the Blue Screamer are Cloyes, but don't look like these.
I'm using Isky 9935 springs with a
open pressure of 590#at installed height.

By the way, 2 weeks ago went 4 rounds to the final round at Cecil county.
Yesterday MANDRA was at South Mountain, a 1/8 mile track South of Carlisle PA
Again went 4 rounds to the final. went 6.901 on a 6.910 dial. on the final pass,
all with a broken wing.

Denny, I have a 9-3101 Cloyes set on hand for current build , this set is supposed to have .005 over size crank gear for align-honed block. The cam gear appears to be billet looks like top quality machineing. What is confusing , is on the box, it shows generic ads. for other products. Gear Drives--Hex a just-- and Billet True. Description on Billet true says "Heat treated billet steel sprockets" The 9-3101 box says"True" so I must assume this is their top of the line gear set. I hope so--- spring pressures will be 250# and 600#. If you should find any more info. on strong gear sets, I would appreciate the knowledge. Allen, dont you have a mirror on that old car? Take your foot off the gas pedal!!!!

[bluescreamer]

Ronnie
Yes I do have mirrors, and I was off the pedal. :doh Should have been
on the brake instead. I was dealing with a 5.94 dial in on the competition.
There's always next week.
This coming Friday Aug 12 there will be a race at Beaver Springs. Called
Flash Back Friday Nite. Most likely there will be 30 to 40 Nost. Super Stock
at this event. Load your car and come join the festivities.

Allen, Thanks for the invitation, but Beaver Springs is a long way from Dallas. Not in our budget. Whenever I cry and moan about break-outs, Barry says, " Its sorta hard to judge the dragsters coming from behind at 140 mph. " It looks quite easy to me. ---Its easy to "drive" while watching from the pits. Good luck, Friday night, let us know how you do.

Denny, please let me know what you settle on. Allen...great job! :clap

Take care guys,

I think i may have learned more about timing gears today than i knew. Ended up ordering a Cloyes Tru roller. Be here tomorrow w/ overnight freight . We want to go to Maple Grove this weekend for the GEEZER"S race.


Good to see your doing well Allen w/ a bad wing & all , will you be @ the Grove ??


Thank's for the help everybody.

I hope to see some gains from the much better new heads & a freshen short block.

I'll post results next week if i get done & am able to go this weekend :clap

Denny
Yes, I should be at Maple Grove on Sunday.
But There is a Flash Back Friday, Large contingent of NSS cars, at Beaver Springs on the 12th.
You could make it a long weekend if the motor gets done. You can camp out at Beaver.
Carl got his motor together this past weekend, he said he's going to Beaver

I'm glad I stumbled onto this thread! I'm about to order my timing set, too! Sounds like Cloyes is the way to go!

Do the timing marks line up like like they should, with the new timing sets? I had another 409 and the marks didn't line up. Not sure what timing set it had.

I got my timing gears today & installed this eve, I degreed the cam w/ lower sprocket in the 4 degree advanced position / i was looking for intake lobe center of 111 degrees, came out @ 110 1/2 w/ a new chain [ perfect !!!] :)

This gear set is really nice looking compared to others i had before / The tru-roller is a .250 roller , it is the top of line set. they make 2 other sets w/ a .200 roller & .220 roller/ like i said in an earlier post , I learned alot!!!!

I'm nearly positive that the gears are powderized metal , seems technoligy is not all bad !

Might try for fri. eve ! / Have a little blonde passenger who can't leave till sat morn ! See ya sunday ! :clap

[Ronnie Russell]

Allen, Could you verify brand and part no. you ordered so we can all be sure. Thanks,

[bluescreamer]

I'm looking at the box as I'm typing. It's a CLOYES 9-3101 True Roller Speed Set.
It looks like a Billet Gear set ,
but like Denny indicated it may be a Induction cast Iron Sprocket that is machined.
I ordered it thru Summit a couple months ago. Will be installed in the
new motor that I'm in the process of building.

Allen and Denny and others, Im afraid we still have un-answered question. As stated in earlier post, I said I have a 9-3101 Cloyes on hand for a current build. I oredered from Show Cars, for a Align honed engine. Their cat. states this part. no. comes with .005 oversized crank gear. I dug out the box my last 9-3101 came in, it has an add-on sticker with Show Cars part no. and says it contains .005 oversize gear. So the question is , Does Show Cars exchange their crank gear into 9-3101 boxes or does the 9-3101 come with this gear? The old gear set is in our race car so I cant get the number off of the crank gear. My reason for bringing this up is that if one of our members orders this gear set because it is the top of the line, then tries to use it on a block that has not been align honed, they will have a heck of a time trying to make it fit. On the other hand, if you try to use a std. gear set of a aligned honed block, the chain slop is unacceptable. I think if we can confirm or deny this fact, it will save our members from future headaches and delays. I would appreciate input from anyone who has a solid answer. Thanks

[Ronnie Russell]

Allen, would you mind posting "stamped number" from crank gear from you 9-3101 ? That way I could check mine to see if it is a std. gear or a .005 oversize. Thanks again.

[bluescreamer]

Ronnie
The part number on the label on the box is 9-3101. There are no extra numbers.
To denot for undersize gears. I assume this is a standard setup.
The crank gear is stamped 103B with a 1-03 which I assume to be the date it was made.
The Cam gear part number is 102F with a 6-03 date code.
If you go to the Cloyes web site. The only listing they have for a 348-409 is 9-3101.
There is a section in the catalog for undersize gear sets , but doesn't
list a set number for a 409 application.
I would call or E-Mail Cloyes and see if they make undersize sets. I don't
know if I was able to help you in your quest ? :dunno

Allen, do you have any way to compare the 409 gears with some SBC gears. I think I have heard the gear set is the same. Just a difference in rollers in the chain.

Fred

[models916]

Top and bottom gears are sbc. Chain length is diffferent. Some mfgs grind off the part numbers as a disguise.

[SS425HP]

That's what I was thinking. Thought I had heard that before.

[fourspeed409]

When I was pricing parts at NAPA the guy looked up the sprockets and chain as seperate part #s. He said the chain part# was farmilar to him, he suspected 460 Ford. He looked up the Ford chain and shure enough it was the same part# as a 409. This was just stock stuff he was looking up. Is it possible to get the gears for a small block and a chain for a 460 ford and have it work? Just an idea.
