I've a Turbo Outrun that I'm slowly fixing up. As you may know, there was an economy version of Turbo Outrun that does not have the shaker or thumper hardware. In mine, there is a centering part that is worn out and cracked and makes the steering feel lumpy around center. The spring loaded bar pushes down on it to hold the center point of the steering wheel.

Does anyone have replacement parts for this?

I've attached pictures of the steering mechanism; the big brass gear drives the sensor potentiometer; the white gear with the 2 screws is centered on the steering wheel. Much simpler than the shaker or thumper versions.

The gas pedal seems to get stuck halfway down. Wondering if anyone else has run into this situation.

Follow up question, does anyone have the side art for Turbo Outrun Mini? Looks like someone did it on ukvac but I can't find the files... website is gone.

Got a solution for the side art, user niknak on ukvac forums took a scan of the Mini Turbo Outrun art and cleaned it up really nice. Another user on that forum, muddymusic, runs http://www.arcadeartshop.com/ can print and die cut the side art and will ship to the US. He can also ship the monitor bezel art, which solves a problem for me, the paint on my bezel glass is flaking off.

So just need to figure out the steering sloppiness fix and pedal issue.
 
I'm toying with the idea of getting a piece of acetal (delrin) of the correct thickness of the original to cut a disc (I've got cup bits), sand it down the 'top' to get the centering functionality so I can replace the cracked disc you see in the pics above. Anyone try this before, any suggestions?
 
Step by step disassembly of the back of the Turbo Outrun Economy Mini steering.

1 - Remove 2 set screws from the gear. Pull gear up and out. Note top/bottom.
2 - Loosen (do not remove) set screws for gear stop plate. Pull off shaft. Note top/bottom.
3 - Loosen steering nut - may have some locking glue that you need to cut with a blade. Need to hold the steering wheel the opposite way from turning the nut.
4 - Remove compression ring and washer
5 - At this point the lobe can be slid up off the shaft, but the potentiometer gear and bracket are in the way. Remove it (2 screws)
6 - The centering bar pulls the bearings down onto the centering lobe to get that rotate to center action. You can release the spring from the pin to swing the bar out of the way.

The centering lobe will slide up the shaft for removal.

So the centering lobe is a heart shaped of some sort of solid hard plastic, with a keyed bronze center piece. The plastic is cracked, which gives the steering a bump while turning. Anyone know where to find something like this or know who might be able to replicate it?

If I can't find a suitable substitute, I was thinking of filling in the cracks with epoxy resin and then smooth it out. Any caveats with that?

Based on some advice from a friend, went the epoxy route with the repair to the steering centering lobe. Blue Tape to get good shape, inject it at the top, let it set and dry 24 hours. Sanded smooth. Worked well. The steering still has some play in it, so I continued disassembling the steering - I determined that it is due to the steering collar being worn out and having some play. Don't know where to source these so I just reassembled the steering handle base and called it decent enough for now.

When re-assembling everything I had a horrid time trying to get the potentiometer centered at a value of H80. It would not stay steady, bouncing horribly through the value range (making it impossible to play, of course). Cursing that the pot must have gone bad, I went to take it apart, and found that it had spun past its range - spinning it back got it to relay stable values. Win!
