I need to run support on the outboard side of my clutches on my RXP project sled. I wonder if anyone has done this and what were the pros and cons of this setup are. Mainly I need to support the outboard side of the primary and I figure the easy way would be a tie rod between the two.
Tie rod between clutches?

Ok, so you want to tie your clutches together on their mount bolts with a tie rod? I'm thinking this would be very very dangerous botht to you and the sled, if that rod were to come apart. LOOK OUT! now you've got a 8000 rpm flail! Also it would be prying on the crank under torque, probably not gonna live very long, IMHO. Why don't you just use a torque stop on the front left side of your motor like the rest of us?

Clutches
I think Reline or fast had this setup. But i think it was with a clutch isolation system(clutch wasn't actually mounted to crank.) the Clutch had no way or flexing thus giving perfect alignment at all times. If you solidmounted the motor I would think it would work just fine or if you had a near solid torque stop arm on the motor. You should post pictures of what you dealing with.

My clutch is isolated from the motor with a splined drive shaft. I just sheared one off due to the lateral torque from the unsupported clutch. Basically I need to stop the lateral force on the primary and the tierod bearing support seems like the way to go.

Anyone have pictures of the redline or fast set up?

Anyone care to calculate the lbs of force pulling the clutches together?
Here's what I ended up building to support the clutch.
Got snow here. Now I need to pound on this set up and see if it will break! Need to do clutching today also.
I don't know how you would mount the tie rod but I think it's a great idea, light, adjustable and I think it would be easier on the crank.
OMG! That's some brace! The thing that worries me is, crank runout is never zero, And two of my P-85's clutches have a tiny bit of runout by themselves (lube crank snout, finger tight bolt, and rotate clutch, you'll see). So, you can index the two, and get the bolt end of the clutch very close to zero. Probably not ever zero though. What effect will this runout have on the brace, or crank, that's my question.

A number of years ago their was a aftermarket brace in development that was a bar with floating bearings on both ends that ran from primary mount bolt to the secondary mount bolt. I believe Duane Watt of the Paragon secondary knew the guys making it.
Also think the blade as it has a short stubby jackshaft has bar with a bearing on it to the mount bolt on the sec.
The risky part is if one of the bearings seizes up!!!!
Good Luck

The clutch is floating on it's own shaft. There are splines between the crank and the clutch shaft. Bearing failure is minor comparied to shaft failure which I've had two of! The outer bearing is the one I would worry about. The inner one gets oil.
