Timing set

[Manu Mach1]

I read that on the 73 CJ engines, camshaft is retarded by 4 degrees, with the original timing set, and when the timing set is changed by a new one, we gain power by loosing those 4 degrees. And is it true that the teeth were in nylon???

So is the timing set has been changed on that picture?

It appears to be a replacement chain to me although, I can't say fore sure. If I remember correctly, it has been a long time, the 72-74 351C had the cam timing retarded 4-6 degrees by changing the location of the crank sprocket keyway and the alignment dot. A 70-71 crank sprocket will not have the retard.

Chuck is correct. The 72-74 351 C had a 4 degree retard at the crank gear with a re-indexed keyway. I had a 72 Gran Torino Sport with a Q code 351 that ran fairly well. But when compared to my 70/71 M code cars, the power loss was evident. The original cam gear would have nylon tipped teeth. If your gears are original they would have a Ford oval and some sort of engineering number on them. (Similar to C8SB-6306-ba crank gear, DOAE-6256-AA cam gear) As Chuck said the 70/71 timing set (which is from the era of cheap premium fuel and high compression) will not have the retard marks. Some aftermarket timing gear sets come with a multi indexed crank gear where you can actually advance the timing. Hope all this has helped some!!

Sure it helps.

I found a sign on the cam gear, looks like DF in a kind of oval, and also CS-6. Don't know which brand it is.

Half inch of slack is the maximum for the chain before it needs to be changed? If so, any suggestions about a timing set and is it necessary to change the excentric roll for the fuel pump?

The timing set in your engine has definitely been replaced at some stage, as the cam gear is not a genuine gear. Also if you are going to change out the timing set I would use the rollmaster red label timing set as they are very high quality and I have used them for many years on many, many engines without any problems. When my Q code timing gear failed, I used one of these rollmaster sets (like I said, I always do) and just set it straight up on standard timing marks (dot to dot) and the difference in its performance was definitely noticeable, it's not going to become a race engine but, the performance is a lot better than the standard set up. As I said use the red label one as they have the good IWIS chain, whereas the blue (economy) set have the cheap Rolon chain which stretch easily. Also as it's that far apart, I replaced everything on mine since it had to go back together anyway eg: harmonic balancer, water pump, hoses, radiator (mine had to be recored as it still had the original in it and was no good only in one corner) as well as a full service eg: oil, filters, plugs etc.

Good luck with it all and hope it all goes well and if you have any dramas, just post up in here as there are many knowledgable people on here only too happy to help.

I found out that Rollmaster is German, good, I will not waste lot of money from the shipping and customs.

Sure I want to put good quality for this part which is very important.

What kind of red label and where can I find it?

Just give me some good equipment I need to set in.

My radiator has been rebuilt to a specialist, his job is only radiator jobs.

Thanks.

.

if that chain is 108.00 us dollars, it is a deal.

your engine looks like it has 150,000 miles on it and may need a rebuild soon.

I thought that Rollmaster was Australian.

yes it is

The IWIS chain is made in Germany but the gears are made in Australia by Romac Engineering. Years ago the shop I worked in was only 10 mins drive from their factory at Sumner Park and you use to be able to go there and by parts directly from them and the more you bought, the cheaper it would get, doubt very much you could do that today. Everything they make is of a very high standard and I've never had one part of theirs fail on me, everything from timing sets and balancers to diff components. The red label sets that I referred too are just in a red box, hence the red label name, part no is CS 3080, make sure you get one to suit the Cleveland engine and not the SVO one to suit stroker/SVO type crankshafts. All the best with it all.

PS: Also if you have any dramas getting hold of this timing set, just let me know and I'll only be to happy to help you out in getting hold of one for you.

I mixed up between Autria and Australia, and as Iwis is made in Germany, to me the rest from Austria

I can'timagine to ship this from Australia to France, would be twice of the price of the timing set I guess.

Here's a company in Australia that ships worldwide, I have dealt with them myself and they are pretty good price wise on shipping and parts prices. The sets come complete with the shim, gears and the chain. Romac get the chains sent to them in crates that arrive on large rolls and they cut and join them together at Romac, I know a guy that use to work there years ago and told me how things were made there, plus he said they had the strictest quality control of any place he's ever worked at.

The part no you want is RM-CS 3080.

you can call summit racing and ask how much it will be to ship the one below.

If I use this Cloyes gear set, do I need to change the excentric part or I can still use the one I have?

And as it's double roller, can I still use the same timing cover? (sorry for this stupid question but just thinking about enough room as gears are wider).

it will bolt right on and all the orig parts will fit . . this used to be one of the top quality sets until all these other fancy ones that are made from prefabulated amulite and irradiated with bozons and neutrinos, came out.
