Question...
My top end starter shaft on which the starter pinion rides wore out and would not 'grab' the pinion to rotate the ring gear.
I ordered a kit that has all of the components for the top end.
So, I have a 16 tooth pinion on the starter now. This has been replaced in the past. Not sure if its the correct one, but it works!!!
Not sure if I have the correct number of teeth on the pinion.
The new kit has 16, the one I am replacing us 16.
When I look up the kit for my engine no., is shows a 14 tooth gear.
The gear tolerances are wide open.
Both 14 and 16 seem to work.
SO.....what is he reason for 14 vs 16???
Maybe more torque?
I expect that my new 16T kit will work just fine.
Please advise the reason for the 2 different gear teeth.
Thanks,
Paul.
 
Kohler, Briggs, Tecumseh, Kawasaki, Honda. Without engine model information we are guessing what you are working on.
 
Here is the info, thanks for reminding me......

I have referenced a 14T pinion when I do a search. A 16T replaced years ago.
My question...with the gear tolerences that seem to be very wide open, why the 14T vs 16T?

I'm thinking maybe more torque ?
Advise , please.
Thanks.
 
Briggs references the 695708 gear which appears to be a 16 tooth plastic gear for the plastic and aluminum flywheel ring gear. The steel ring gear uses the 14 tooth metal gear. part number 593935
