Can anyone tell me the size of the prop bolt on a G62.
Thanks P51Tom

10mm

The G-62 has an aluminum hub. A prop bolt wears out the threads rather quickly.

The hub holds up better to affix a stud in the hub and use a washer and nut to retain the prop.

In my case I used a stud and a spinner nut to retain the prop and spinner.

I completely agree. I always install studs with Loctite in my prop hubs.

High strength hardened studs can be gotten from auto engine rebuild suppliers. Ask for exhaust manifold studs.

...or, once the hub strips, you can buy a Helicoil 5546-10 M10 x 1.5 Metric Coarse Thread Repair Kit (~$30), do the repair yourself and continue using that nice 10MM bolt that's already been drilled for the spinner bolt! Don't forget...you'll also need a 13/32" drill to prepare the hole for the Helicoil. By doing it yourself, you'll get the satisfaction of playing "machinist." Isn't this hobby a kick.

BTW...I have done a couple of the G-62's that were modified with CH electronic ignitions (extended hub) by installing 3/8-24 Helicoils (P/N: 5528-6) - stacked 2 in the hole and cut off the excess. This one takes a 25/64" drill bit.

You can go 3/8 but the props are all drilled for 10 mm so it is a little loose on a 3/8 stud or bolt.
