Superjet Steering System

Hi all, I think I found a great way to adapt an aftermarket turn plate to the stock Superjet steering system.

What you need:
- (2) Bronze Flange Sleeve Bearings (16mm ID, 20mm OD, 20mm L), $3.00 at your local hardware store
- M16 x 55mm Hex Head Screw, $1.30 at your local hardware store
- M20 Washer, $0.90 at your local hardware store
- Double Split Shaft Collar (for 16mm shaft), $15.00 at your local hardware store
- Stock Nylon Bushings from your Superjet

I should have an image of everything you need to buy. You may want to make sure everything is Stainless Steel. If you can only find a Black Oxide Shaft Collar, simply replace the screws that come in it with SS Screws, and keep it greased.

See the attached exploded view for how it goes together (The silver plate is the turnplate, and the black plate is your pole). The shaft collar is what holds it all in. If you want to really tighten your steering, buy any M16 Nut, tighten it against the bottom of the shaft collar, then tighten your shaft collar, and remove the nut. Grease EVERYTHING. These components should all fit very tightly together. I haven't ridden on this setup yet, but it feels VERY smooth! I hung off my bars and banged down on the ends like an angry gorilla and it seems to stay tight. I will update after I ride (maybe a week or 2 in CT).

Yea you could just use 2 jam nuts. I just don't like fiddling with them to get them exactly how i want. I rode yesterday. Steering was very smooth. I only posted this because I had a hard time finding advice as a newbie, plus I never heard anyone mention the sleeve bearing, so I thought I would share.
 
O I am definitely leary as well. Shaft Collars don't do well with shock load, so i'm kinda expecting it work its way down the shaft with hard landings or falls. I will update in the future. They do make threaded collars. That would work super well probably!
 
Been riding with this set up, as shown, for several weeks now (maybe 8 hours on it). It is holding up well. It hasn't loosened up on me yet. Still feels smooth. Hard cornering, subs, riding on the hood, 180 stabs, and a couple failed barrel rolls.
 
Just pulled this set up apart for the first time. 3 seasons of use, riding twice a week. Some surf riding too. Had to adjust the collar every few weeks. I do that by loosening the collar, turning a M16 Nut up against it, then tightening the collar, then backing the nut off. Takes 2minutes. I also noticed you can very finely adjust how easy/hard it is to turn the bars with the Nut tightening method.

I have an X-Metal Aluminum pole I am setting up now. I had to purchase different sleeve bearings and also Nylon Washers (could not use stock bushings). $20 in parts. Other than that it will be the same set up. We will see how that works!

Good to see feetback on this! Many times we never see the outcome!!!!!!!
 
Looks good, if you grab a longer bolt that is not fully threaded so that the bushings and shaft collar ride on the unthreaded part it may even tighten it up a little. The other thing you could try that might prevent you from having to re-adjust the shaft collar would be to drill and tap both halves of the shaft collar for a set screw, then once you adjust the shaft collar use the set screws to lock it in place. Sounds like it works well without it, but it may also prevent the monthly maintenence

I like your set screw idea! Also, your shoulder bolt idea is good too! I just found some that would work on McMaster! lol maybe I will order one sometime this summer.
