RAF prerotator

[bones]

Ok I think I got 1 of these coming in was just wondering if anyone else was thinking about this I might be able to get a bulk price.I have just selected the parts needed ie top bendix, inner and outter cable, bottom clutch assemble.So there is brackets needed and motor pulley, reason for this is we are using rotax for power plant.It looks like about 2000 Canadian dollars plus freight and gst

i still need anatha one, maaate.

Sounds good Bones. I"ll give ya another ring to get something sorted.

[bones]

Hmmm after i woke up more and read it properly there is the ring gear missing and one other thing not added in so it might be a touch more, will let you know.Angus i send you a msg about it through the site here.Birdy yeah got sick of waiting for the number from you

I wouldnt mind one but can they be hooked up to a suby 22.2 ??

I wouldnt mind one but can they be hooked up to a suby 22.2 ??Brian, that is one serious motor you got there, a 22.2 man that must pump out some power They are made for the subs, so yeah no probs at all, just be a few more parts for yours, and all you need to do is change out the ring gear and mount the bendix up the top.

Bones,Have you tried pricing the Sparrowhawk prerotator? It is pretty much the same design as the RAF but MUCH better built and with more mechanical advantage on the clutch assembly lever.With the RAF & SH prespinners, you will need to allow for the clutch plate and shaft sticking out about 4" past the centre line of the drive belt and make sure it clears your prop.Or there is always the Wunderlich job which is heaps cheaper than both RAF & SH.See the email text below for Wunderlich bits;Hi Scott,I have been giving your idea some thought. I have sold several lower units to 912 / 914 operators. I have no idea how they attached the bearing housing assy to the gear box. I wish I would get some photos from them. I do not have a 912 / 914 at my disposal or I would manufacture a bracket mount.My lower units would require a drive drum behind the prop, but are compatible with the RAF flex shaft.The better bearing housing assy runs around $160.00 USD Drive drums around $75.00USD Tom Milton, OwnerCalumetair Inc.3441 Washington, Lansing, IL.

Hoges,I been trying to get Tom to do a unit for about 2 years for the 912 motors, i ended up saying the last time i talked to him i would send over a gear box off one so he could mould off it, but i cant get my hands on one

I was going to fit a Rotax 914 to my RAF and had designed a pulley and was ready to be machined so I could fit the RAF pre-rotator but I bought a Sparrowhawk in the meanwhile and that was the end of that. I still have the drawing if you want it.Hoges

Bones, duno bout neo, he"s busy chasen bentnecks n staren at the wite line i think.Brian, not sure wot your soob is setup like, but youll need lefthand rotation prop for a raf spinner. [ anti clok lookn from behind ].

[ anti clok lookn from behind ].Yeah, I think you are right Birdy, I might just forget about the idea for the time being.

[bones]

Okay here"s something a little left field, i cant get the basically same type of deal off Wunderlutch(spelling) for about 1k US which might mean about 1500-2k AU, still need to build a bottom bracket and mount the top stuff.Food for thought, i might go this way myself yet.

Bones/Birdy. I have two ref pre-rotator cables one brand new and one s/hand if you are interested $500 for both Plus post they are here in WAPick
