WackenSS Posted May 4 Author Share Posted May 4 51 minutes ago, SEBSPEED said: What do you have cooking? I'm interested to hear your findings. I am aware that the newer iteration of the C15 does not use a shaft oil seal, and so all the oil needs to be located below the centerline of the shaft. I've taken that into account with my current installation. I've also added an oil cooler for the Rotrex oil. I'll post my findings when i am sure everything is repairable and quoted. The "gen2" rotrex C15 explicitly states that oil reservoir can not stay in Dan's location. The reason for this is that the rotrex is a dry-sump with scavenging pump and it will start sending oil out behind the impeller. Did you fab something nice already?

I did, I mounted a new tank on the right side behind the fairing. I also reconstructed the cooling system with a different radiator configuration so I could add a cooler for the Rotrex oil. 1 Quote Link to comment Share on other sites More sharing options...

I'm pretty sure the oil temps are ok, but that's a guess based on the climate i live in. I'll make a temp sensor thing this year just to confirm. Do you have the gen2 version? Pictures should be a must from what I've seen of your fab skills before. In other news I've decided to do this the hard way. I'll put everything together, rotrex fixed and unmodified, stock headers, no rapidbike, brakes and suspension and put in on the Dyno for fun and find the weight numbers before i start the diet and all-around upgrades. This should go rather quickly - then for the upgrades, and it will also include a billet impeller either before or after the headers/rapidbike.

I have an earlier model Rotrex from the original Toro production run. I did the oil relocation to save time in the future in case it's needed, and because I was re-plumbing the system to add the cooler anyway. Rotrex states in their texts that an oil cooler is mandatory on installation, so I figured it can't hurt. I have been taking pics along the way, I'll post them later when I get the bike done and I can relax a little. Do you have someone that can balance the rebuilt rotating assembly for you?

There is no need to balance this assembly. The shaft is supported on 3 large rollers and is machined as a single part so this is naturally balanced. The impeller is cast OEM and balanced 2 ways alone before it is put on the shaft and fixed with a steel nut on the first versions and aluminium nut on the later gen1's Your setup certainly needs pics 🙂 I guessing this is not the warbird?

Nice that you don't have to balance it. I am installing on my 2005 VTEC which still has fairings. I had been collecting parts for about 10 years and I got the itch to put them all on it at once 1 Quote Link to comment Share on other sites More sharing options...
WackenSS Posted May 9 Author Share Posted May 9 Valve cover cleaned up nicely, radiators even more so. I even found som hidden developing issues needed sorting. The last pictures are just for fun. Rsv4 water pump housing vs the VFR. RC51 Left radiator vs VFR Therese parts i have lying around just to see if there is any possibility of fabricating something already accessible to me.

SEBSPEED Posted May 11 Share Posted May 11 A pic from the other day. I have since installed the upper cowl with lights and am just waiting to get in the paint booth to finish the right side panel, then it will be done. 5 Quote Link to comment Share on other sites More sharing options...

Is the lower chin fairing in the "V" going to fit over the 8th gen rad? Mods for that in store? Quote Link to comment Share on other sites More sharing options...

So you will have access to the dipstick through a hole in the right panel right? You said you have been gathering parts for ages, but you had the complete SC kit minus the cooler or am I wrong? No outboard support bearing on the rotrex? Did you fab the toothed pulleys or are they the last revision from Dan? Where did you put the rectifier? Could we get a look under the hood Please 🙂😳 1 Quote Link to comment Share on other sites More sharing options...
WackenSS Posted May 15 Author Share Posted May 15 Parts have arrived and i am pretty confident this will be a good working unit again. A small change in plans. It is not possible to change the impeller without a total teardown of the rotrex, while interesting enough it's not something I want to do again just to change the impeller. Cast out, CNC in! 3 Quote Link to comment Share on other sites More sharing options...

Could we get a look under the hood Please 🙂😳 No dipstick, I added a clear tube to indicate oil level I bought a complete used A&A kit, one of the original 6g kits. I made the oil cooler from a 6g radiator. New larger SH847 rr is mounted on the left side of the frame now. I didn't get a chance to make a thread for my rebuild before leaving on a trip, but I plan to make a list of mods with pics when I return. 1 Quote Link to comment Share on other sites More sharing options...
