1909schacht Posted May 9, 2017 Share Posted May 9, 2017 Came across this neat gear it appears to be made of pressed fiber or some type of composite, slanted teeth suggest no chain involved just gear to gear but to WHAT ??? does not seam too practical Any Ideas ?

Larry Schramm Posted May 9, 2017 Share Posted May 9, 2017 I would say cam shaft gear. Any numbers on the gear? Link to comment Share on other sites More sharing options...
F&J Posted May 9, 2017 Share Posted May 9, 2017 Yes, cam gear, AKA "Timing gear" Many people claim it is not a good idea to buy an old NOS, due to lost strength... but if it can't be found elsewhere, someone may want it. Link to comment Share on other sites More sharing options...
keiser31 Posted May 9, 2017 Share Posted May 9, 2017 A lot of cars used those types of fiber gears. Link to comment Share on other sites More sharing options...

TheMoneyPit Posted May 10, 2017 Share Posted May 10, 2017 My first thought was Model T Ford aftermarket (original was steel) but A is a good possibility too Link to comment Share on other sites More sharing options...
Brass is Best Posted May 10, 2017 Share Posted May 10, 2017 Looks like a Model A Ford to me as well, but with out dimensions it would be hard to know for sure. Link to comment Share on other sites More sharing options...
Spinneyhill Posted May 10, 2017 Share Posted May 10, 2017 Studebaker Commander used a fibre timing gear. Give us some dimensions. Diameter, width, no. teeth, centre hold dia. ? Otherwise it is guess work. Link to comment Share on other sites More sharing options...

28 Chrysler Posted May 10, 2017 Share Posted May 10, 2017 I had a composite timing gear in a "T" Ford similar to yours, it was fairly quiet. Post the size and you may get an answer. Link to comment Share on other sites More sharing options...

Mark Simmons Posted May 10, 2017 Share Posted May 10, 2017 This looks like the cam gear for several years of Chevy six cylinder 216-235"s I used to replace them with aluminum ones. I think the last one was on a 46-48 coupe. Link to comment Share on other sites More sharing options...
