Starter / Generator

[f350ca]

Have a Hitachi Starter / Generator off a Yamaha golf cart that I want to repurpose to start the Wisconsin for my wood processor. I need to know the maximum recommended rpm these things are designed for, so I can design the belt drive, want to give it as much mechanical advantage as I can to spin this thing. I've scoured the internet, hundreds of hits for rebuilt and new ones but no info on specs. Its model number is GSB107-02 , no info on the unit, I have and can find a wiring diagram but thats it.
Thanks
Greg

I found this cross reference list that might help.

Thanks Ed, tried searching through those and still can't find any specs, particularly recommended max rpm.

What is odd, is the gas engines they bolt to are rated at a max of 3600 rpm. Yet, when I look at pulley ratios that would appear to give double that as a generator, which seems really high!

I started hunting at exploded diagrams, and just got really confused when I found a 10:1 geared application (which implied just a starter).

Stopped into the golf course maintenance shop and got some info on the unit. Apparently they're rated for 8,000 rpm continuous and 12,000 rpm burst for 3 minutes.
Good thing I inquired, was going to try a 14 inch pulley on the engine which might have done it in, a 12 inch will give me 8400rpm, close enough for country work.
