Help needed identifying gear

shapeaholic · Dec 28, 2020

Greeting all,
I am hoping someone can help me identify how to specify this spiral bevel gear so I can search for a replacement. ( original no longer available)
It is half of a bevel set. This one is 22 teeth the other is 25 teeth. My not so accurate calculations lead me to think is may be mod 2.5.
The dimensions are shown in the following pictures.
Thanks in Advance

Not going to end well, its is a spiral bevel, gear.... you may have to rebuilt as a straight bevel...Phil

search for a replacement

Not happening short of the exact same piece of equipment laying there as a parts donor

The reason is such things always come in matched pairs

You will find a suitable bevel set in an outboard motor.....many sizes and ratios....thats where I look .

What ?
You're not going to try "Randy's Ring & Pinion" shop ???....

Another very useful bevel gear source is the 1940s IH KB7 truck diff .....the differential (side) gears have quite fine teeth for a truck diff,and run smoothly in mesh in a milling head.....Later IH truck diffs have coarser teeth ,and will run OK in mesh ,but not quietly.
