Re: Timing gear
I prefer the aluminum one. If'n you go for a fibre gear get the laminated one, not the "macerated" one which have been reported to have an early failure rating.

Re: Timing gear
On mine, the fiber separated from the aluminum carrier. I didn't want that to happen again so I went aluminum. I heard the warnings about noise, but did it anyway. I notice no difference in engine sound from the aluminum one. It is plenty quiet.
Also, if you are following Les Andrews' instructions, be careful. I seem to remember that he misses one hidden bolt in the timing cover...on the bottom on the right hand side. If you try to force the cover without removing that bolt it will crack. One more thing, no matter which gear you use I recommend that you drill out the timing dimple in the new gear a little larger. You will thank me when you try to find TDC with the timing pin.

Re: Timing gear
Aluminum. You'll sleep better at night knowing it will last as long as the car.
They will run quite, as long as your gear back lash isn't too large.

Re: Timing gear
I had a new laminated gear installed a couple of years ago. At 75 and driving about 1,000 miles a year I feel pretty confident. I know many like the aluminum ones, but our very experienced local Model A mechanic said he had changed out quite a few that ended up being too noisy. The laminated should last much longer than the plain fiber type.

Re: Timing gear
I have never noticed noise from a metal timing gear on a model A.
I think I hear a little extra noise on my ‘51 V8 with aluminum gear but it doesn’t bother me. I hate roadside restorations. I have put metal gears in at least 15 model A cars.done at least 15 model A cars. After doing seven for one guy he never mentioned extra noise. I remember on one I did with the engine still in the car. I removed front mount and had to remove bell housing/transmission bolts and pulling the engine partly off the transmission. Nasty job to change the crankshaft gear. Even a two piece gear. I prefer the bronze gear, second best would be the aluminum gear. |

Re: Timing gear
In about 100000 miles of A driving over a couple of decades I have had 1 fibre gear mash up and 1 fibre gear loosen on the central metal section. So from then on it has metal gears only for me. Les Andrews book diagaram p 1-325 is also slightly wrong .. Here'sa picture from Tom Wesenberg showing correct relation of crank keyway to timing marks. Miff... I wrote an article on how to change the timing gear a few years ago, if you want me to email it you let me know.

Re: Timing gear
Fiber gears on Pontiacs in the late sixties used to fail.....I know that

Re: Timing gear
I'm a racer of the A/B Fords. I use bronze gears on my Bonneville engine but aluminum on my street engines, which I also run on hill climbs. Aluminum is plenty strong and reliable.

Re: Timing gear
Dan Mceachern's gears are perfect-
Aluminum and bronze. We made a fixture to original Ford specs which enables bench testing a gear set before installation. Oh and that’s one of Brierley’s R-1 cams behind Dans gear set.

Re: Timing gear
I have one of Dan Mceachern's bronze timing gears. Be sure to get the matched set crank gears also. Cheapest insurance you can buy.
