Stripped timing gear
I am replacing a stripped gear and was wondering what else I should look for that might have caused the strip. If the gear was old and weak, that's ok, but what what else could cause a good gear to strip?

Re: Stripped timing gear
There are many things that over a period of time could add to a failure.
One thing you know for sure with a Model A is that if you drive it. Some day you will be replacing the timing gear. In a high mileage engine things move around more. The fiber gear is made to take that movement and fail first. Rather replace a timing gear than cam or crank shaft, etc. Not a big job. Enjoy. |

Re: Stripped timing gear
anything that could stop the cam would strip the gear.

Re: Stripped timing gear
I'd recommend taking a good look at the crank gear for condition, such as pitting/rust.
And also take a look at the camshaft and distributor drive gear. |

Re: Stripped timing gear
A rough/worn crankshaft gear, too little or too much clearance between the gears will also cause failure. If you stripped the teeth, the teeth will be in the pan or the fibers will be lodged against the oil pump screen. I have also seen the oil return passage in the rear main cap plugged with the remnants of the timing gear. It is good practice to check the pump and the rear main cap passage and drop tube.
Sorry to hear you had trouble. BTW: Just came through your lovely State while on a 4 week road trip. Drivers in Michigan were very polite... Good Day! Last edited by Dave in MN; 10-12-2017 at 11:26 AM. |

with an aluminum one. It was noisy but it worked until I had the engine rebuilt I now always use an aluminum or bronze timing gear. |
