regarding the proflex starter bit

originally was going to put a hex on my Fury so i can use the hex starter adapter for the fury as the raptors but i realized i liked this proflex start system better (smoother and seems to be less fuss and wear). so now i'm thinking of using it to start my raptors by removing the hex adapters on those..

- has anyone done this w/o damaging the pro-flex unit?
- do you need a special shaft to accomodate the pro-flex's one-way?
- i heard the pro-flex's one-way can lock and PITA to remove? true?

hey, thanks in adv.. i'm trying to avoid damaging this starter adapter since it cost like fifty bux.

cya.

I didn't have good luck with the proflex. The oneway bearing broke. I put 6mm hex adpators on everything.

Adapters
Ricks and MA both sell a 5 - 6mm adapter so that you can use a proflex on the raptor.

It's really personal preference, I've had mine for about 4 years, a little tri-flow in the one way bearing every once in a while and it lasts.

The only plus about using hex is that you can use someone elses starter if your battery or starter is dead. It sucks being the only proflex user at the field!

I think on the raptors the hex start needs to hold the shaft up so the clutch dont ride on the clutch housing. You probly get around this .

As mentioned before the adapter would have to be replaced by a locking collar or something to keep the shaft in place - the shaft also has flats ground into it for the grub screws in the adapter - these make the bare shaft unsuitable for use with the proflex.

I tried an adapter a while back when I first got my R90, but the stuff the adapter was made of was too soft and pitted easily - trashed the proflex on the second start. Ended up using the supplied hex adapter for the Raptor and save the proflex for the Furys.

thanks for the replies.. as pilotError mentioned, you can use an adaptor to hold the raptor's starter shaft up like this one (though you may have to trim the raptor's starter shaft to correct length to hold it up properly)

true, it is kind of a bummer if you're the only proflex user but it also sux when someone who's having an engine starting problem drains your starter battery by borrowing yours..

i guess just a preference at this point. but obviously going pro-flex on all means a $50 replacement if it breaks rather than a $20 hex wand..

The old style R60 start shaft was 5mm, the newer style is 6mm. If you have an old 6mm start shaft or any piece of 6mm hardened steel rod, you can just cut a piece the length you want, and JB weld it into the stock R60/90 starter cup. The starter cups are very inconsistent, with the mfg process sort of just displacing material as it's formed. If you clean out the area under the hex part it is round, and long enough to center the shaft you will epoxy into it. The voids between the hex sides and the shaft will pack enough epoxy to hold it well. You can also cut small grooves in the shaft to give additional grip. I'd have not thought that JB weld would be strong enough, nor would I be able to get the shaft centered properly, but I've had no problems starting a YS80 like that for over 2 years. Best of all you probably already have all the pieces you need to try it.
