Oversize and Undersize Aluminum Cam Gears Hi All- if anyone needs an oversize or undersize cam gear to fit an engine with an incorrect cam to crank centerdistance, I'm in the middle of making a batch of aluminum cam gears and can cut a special for you without having to charge a setup fee. Send me an e-mail at [email protected] if you nave a need. I normally stock a variety of sizes, but sometimes an engine needs a special, so nows the chance. Thanks all. Dan

Re: Oversize and Undersize Aluminum Cam Gears Dan, how are you suggesting for a home hobbyist to measure what size they would need?
|
Re: Oversize and Undersize Aluminum Cam Gears Thats a good question.

Re: Oversize and Undersize Aluminum Cam Gears I needed a .005" undersize gear a long time ago, Dan made one for me and it worked fine.
I run his gears in my race engine, never a problem, and I have 140 lbs. spring pressure and turn the engine 6,000 RPM! |
Re: Oversize and Undersize Aluminum Cam Gears I to have run Dans gears. They are always right on.
|
Re: Oversize and Undersize Aluminum Cam Gears I also run some of Dans bronze gears with his name on them . Dans gears are most likely the best timing gears available . I've never had a problem of any kind with Dans gears .

That really is not the point here. I doubt you can find anyone that would diss anything that Dan makes, we all will agree that Dan's quality is top-level, ...but my question was if folks are requesting that he make a special sized gear outside of his normal spec sizes, how does a typical home hobbyist measure to know what special size gear to order? |

Re: Oversize and Undersize Aluminum Cam Gears Setting up a dial indicator and checking backlash isnt difficult.Setting a proper baseline is,a new crank and cam gear (stock size) would tell the story,imagine anyone looking for an under or oversize one has backlashed a new set.

Re: Oversize and Undersize Aluminum Cam Gears Lash can be measured with a feeler gauge cut down to a point so it slips between the gears. The hard part is trying to figure what you need when there is no clearance because the cam/crank indexing was off and the crank/cam gears are too close. If the cam gear will slip all the way in but have no clearance, a /002 undersized worked for me. If it is really tight, I would describe it to Dan and trust his judgment, recognizing it may take a time or two to get it right.

I corrected a block that was too tight on a full pressure insert engine by sleeving the mainline back to standard to the camline. I could have sleeved the camline back to standard also. About the same amount of work. |
Re: Oversize and Undersize Aluminum Cam Gears Buy an aluminium one from the suppliers. If it doesn't work get one made.
One well known engine builder doesn't do metal timing gears. Do what you haveta do ... |
