I read awhile back that a few were working on putting the double roller timing kit from a 1982 1.8L cavalier into the never 2.2L and 2200 engine. Through my searches I never found anyone who actually completed it or talked about it in detail.

Has anyone completed this swap and what modifications if any needed to be done. The reason I am so interested in this, is because I can get a timing gear set through Napa, which in my oppinion is the best type of timing set available.

The Napa set doesn't include the tensioner or guide, both of which are no longer availible anywhere. It has been speculated that stock 83+ tensioner/guide assemblies may be sufficient, but we're not sure. I'm short a guide (but have the tensioner), which I will hopefully be trying out soon enough. The measurements needed for the extra boss can be found on PJ's server, the link is in the 1.7 rocker thread and still valid.

If I am thinking correctly, the gear set wouldn't need the tensioner assembly as there is no chain to keep tension on.

I would love to see how the knock sensor reacts to a gear set in a 2200, HPT hardware would be a must. Does anyone know if HPT can change the sensitivity of the knock sensor?

The '82 timing set is a chain. You will need both a tensioner and guide, otherwise it rattle like crazy, and trigger the KS and eventually breaking the chain. As OHV notec stated above, we're still waiting to find out if the '83+ tensioner and guide will work.

I have yet to see an LN2 with a gear set,although I know Russ had tried it. IIRC he just couldn't get it under the timing cover.

There is also a gear set available, which can be seen via the link in my original post.

I am wondering if the double roller set will clear the timing cover.

if i remember my directions properly, you'd need a reverse grind cam for that to work.

I was wondering if that was the case, however on the Napa page it doesn't mention a reverse cam grind anywhere.

Just trying to explore more options for the 2.2L/2200

a chain rotates the gears in the same direction. but when you have two gears, one will be rotating in the opposite direction of the other. if you have THREE gears, the direction is changed TWICE from the drive gear, and you keep a standard rotation. i know of no company that makes a reverse grind cam for any of our engines. good luck, i doubt that gear set that you listed is actually for one of our engines. they may have just listed it as a generic part, and throw it in the timing section.

That is definitely not a timing set from a 2.2/2200. It does look like the timing gears from a 2.5L Iron Duke or Chevy L6 motor.

The 1.8/2.0/2.2/2200's only came with a timing chain, with the '82 1.8L being a double roller set. To use the '82 timing set, you need to machine the center of the cam gear to fit a roller cam, drill the block and epoxy a spacer in to fit the damper. All other timing sets are silent link, even the "Heavy Duty" timing sets.

Hey, bud.

Fairly sure that timing gear is for an old 230 / 250 cubic inch inline 6 engine. Try looking up a 1985 Chevy Truck, C10, 250 engine, and that gear set shows up as a "high performance" option. I know the old sixes had a gear drive. The 82 Cav never had gears. (Helps to be old sometimes. )

Just for grins I spent some time researching parts yesterday. Advance Auto lists a timing chain and damper for the 82 Cav from S A Gear (I've posted this before). The chain is a single roller rather than a double roller, but it should still be stronger than the silent link type. Funny, but the chain also fits Chrysler and AMC engines... ??? Anyway, i believe that the single roller chain may work with the tensioner from the 83+ cars without an issue. Just for grins I'm going to have my local Advance order the chain and damper so I can compare them to the tensioner. Maybe there's still an "upgrade" for the stock chain assy.

Any news on this?

Things didn't work out as I expected.



This is not the 83+ tensioner.
I'll have to look at the other one again.

-->Slow

You're right, that's the 82 tensioner, which nobody seems to have any stock of...which means you now have a full '82 double-roller set, correct?



fortune cookie say:

I don't have a full set yet. A member of the .org sold me a chain and gears for $20 but it never arived. I still have his promise that he'll make it right, FWIW.

Local NAPA said they should have a chain set in hand tomorrow am.

The tensioner above was an accident. A girl happened to hit the number and the factory showed one in stock. I was dancing as she asked "would you like it shipped overnight for an extra dollar?" Hell yeah!

I don't believe the 83+ tensioner will work with the older gear set without modification. The diameter of the gears is much larger. If they haven't sent the parts back yet I'll try to take some pictures tonight.

Was the gear set from Mike (HotRodV6)?
I mentioned the diameter when I received mine, but it is not much, and I thought the chain might be wider or something and make up for the space. I still need to get my cam gear machined before I know for sure...
As it is, I'm hoping I can get by with using the 83+ guide portion by slotting the mounting holes, as I only have the 82 tensioner.

No, it wasn't Mike. Funny, though. He showed up on a truck forum I'm a member of.

The same AAP store I bought the tensioner from said they could get a damper. It's 7 to 10 days out. LMK.

The silent link chain isn't as wide as the double roller chain. But the guide for the later chain narrower must be narrower? Will it provide enough support? I actually have some Teflon strips here which are about the right width to make a chain guide. That was one of the options I was considering if I couldn't get the tensioner. It's easy to put a couple of them in the mail. I also seem to remember that the 2.3 Quad 4 engines used a double roller chain with a small tensioner. Maybe those parts could be adapted.

The 82 chain set had already been returned. When / if NAPA comes through I can make some comparisons and take pictures.

-->Slow

I'd love to have that damper

I'll see what I can do.

No chain yet, but another V6 cav arrived at the shop to be stripped today. This one's 5 speed equipped. WooHoo!! If I can't beat 'em, I'll remove 'em from the competition altogether!

-->Slow

Interested to see what all comes of this.

Advance Auto Parts' damper arrived yesterday. Still waiting on Napa chain set and damper. If Napa comes through I will have an extra damper needing a home.

-->Slow

How did you find 2 dampers?!?
*dibs*



fortune cookie say:

Well, technically I've only found one. The Napa part is in a dark, cloudy place named "Shipping" which no one seems to know anything about. I was supposed to get a call today with exact coordinates, but I haven't heard a thing.

If I end up with two, you're first in line for the extra.

Followup post:



Complete set of parts plus one extra damper. Part numbers as follows:

Chain and gears: NAPA 103060
Damper #1: NAPA 9-5138
Damper #2: S.A. Gear (Advanced Auto) 7138
Tensioner: S.A. Gear 9137

Some more notes... Cam gear has GM logo and numbers forged / cast on the front. Damper and chain set still available from NAPA. Mine took a couple of weeks to arrive. One damper supposedly available "factory order" from S.A. Gear. After I ordered my tensioner they showed zero in stock at the factory. Part number 73053 is listed as the timing set for an 82 Cavalier in the Advance Auto Parts computer. That part is actually for an AMC 2.5L engine. The correct number is 73052 which is not available.

Also, here's another photo for thinking about:
