Does anyone carry an advanced gear that is NOT nylon?
How do the nylon ones hold up in use?
Scott call Dan McEachern in CA all of my gears come from him, his bronze gears are works of art
Dan's da man.
I was converted to nylon, lasted for years till it went south. The shredded teeth plugged the oil holes in center and front main. Melted down the center main. I will admit it may have been partly my fault. Shifted the Warford from under drive to direct at to high an RPM. It was my first time on tour with the Warford. Car ran so I could load and unload off trailer but had a nice thump.
I have an aluminum timing gear bought through Antique Auto Ranch in Spokane, WA. They drilled the gear 7.5 degrees advanced and I like the hill climbing ability even with 3:1 gears in the rear. (Ok, a few more modifications to the engine like a reground cam, Prus head, SU carb and headers )
I drilled my own gears. Used aluminum gears. Made a jig so it's easy to set up. All the information is on the net.
You can take a standard gear and redrill it with the holes off 90 degrees plus 7-1/2. I had to think about it for a week before I decided which way was correct to go with the 7-1/2 degree offset, but it worked fine.
Why 7-1/2 degrees? Why not six degrees or five degrees? Does anyone make an adjustable cam gear?
Not that I know of, but Jegs offers offset dowel bushings that might be usable on a T cam gear. You would have to drill the hole in the cam gear larger to accept the offset dowel bushing.
Scott: Check your email. Dan
got it, see yours...
I can always supply 7Ĺ degree advanced gears by adding the extra holes at 90 degrees to the stock position if I don't have undrilled gears on the shelf. I try to keep a few in stock with both stock and 7Ĺ degree advanced holes in both bronze and aluminum. Dan
Mackay, read this.
hey Dan Mceachern,been trying to order gears,sent you email and phone call,whats the best way to order?
Randall- you have an e-mail from me. Dan
Dan it must not be working Going to send another now let me know if you dont get
dmcgears at yahoo dot com
DAN order sent
Regarding Macky's question, I too wonder why 7.5 degrees was chosen, other than it being 1/2 tooth different from stock.
It would seem to me that the optimum cam phasing for a given cam would have to be determined on an engine dyno or actual in-car testing, which might be feasible and desirable for Montana 500 use (maybe an existing speed secret?), but a bit of overkill for the average hobbyist.
We had two men in our chapter that told me years ago the T would develop a lot more torque on the bottom and climb hills better if the cam was advanced by 1/2 tooth. That just works out to 7 1/2. Maybe the perfect number would be 6 3/4 or 8 1/8 but I just followed their advice. I have a car with 3:1 gearing and it needed help. You could be right in that 7 1/2 isnít the best solution but it was very easy to make a jig from an old gear and do the 1/2 tooth mod.
The two men that told me that probably knew more about the model T than anyone else I know. They were Lynn Cook and Martin Alexander. Both now gone but not forgotten.
