Richmond 2-speed won't stay in gear

any trans folks have a good guess on why this trans jumps out of gear during a race? I loaned it to a guy and he has run it 5-6 races but has to use a bungee cord to keep it in gear.
It uses a special synchro ring which broke years ago which I had to replace and I can't see it being worn out as it has only 30-40 races on the trans total.

Depends on how hard he is on them when shifting.
It only takes once to trash one.

I'd pull the side cover and look for a bent shift fork. Look for the slider to not be fully engaged.

Does it do it on or off throttle?

jumps out under power, but would probably jump out when lifting too.

Could it be moving around on the bell housing? Is the bell straight and flat? Are the bell housing locators long enough if this has a mid plate?
Has the drive shaft ever bottomed out on the splines or knocked out the rear seal?
Does the car have a tail shaft support? if not, I wonder if chassis flex is pulling the shifters enough to pull it out gear?

flex is something I didn't consider. It is a 25 year old metric chassis truck, has been updated somewhat. Has no rear mount.

If you get a practice night perhaps disconnect the shifter and leave it high gear. Push it off and run some laps.

check bellhousing alignment and parallelism between the back face of the bell and the flywheel. Theres a company in syracuse that has steel shift forks made in USA. T10 sidecovers can be finicky. Their detent system is a lot more complex than the Muncie stuff. Hows the fit between the slider and the hub? You can use an Italian Muncie Torque-Lock and use the Muncie 297k strut and spring kit. I also know where there are billet struts/keys/dogs for the Muncie

If your guy has a Hurst shifter; I know Crash Enterprises in Wisconsin has great deals on restored Hurst pieces, overhaul kits and also customized installations.

Imsport.
Is this a 2 speed made with the road-racing lug style synchro ring, or the dedicated Richmond 2 speed dog-ring setup that used the stock fork arrangement?

The lug indexed synchro ring setup uses stock gears...When Regal Beloit sold Richmond to Midwest Truck, the gears were tooled up 'off-shore'. You may have an issue with the included angle of the synchro ring and the gear being different...and having trouble. You'd have to look at everything with an optical comparator. I have one and would be happy to do it.

Is the lug plate removeable from the gear, or is it a 1-pc forging? Are they spur gears or helical?

The lug plate is replaceable, one broke the first time out when the trans was new.
I don't recall it having spur gears but am not sure.

You CAN get an oscillation from that snapring'd lug plate on the face of the gear. If the fit is too loose and hes WFO in high gear, an oscillation plus a worn sidecover, bum fork, bad tire/rim/brake balance, etc...could tip it over the edge. Youll usually see some fretting on the gear/lug plate if you look close with a lupe in the splines, and the snapring will have a shiny spot. Some guys will also 'dress' the lugs themselves as they get burred up in-use with a dremel or whatever. Once you lose that square edge; it becomes a ramp.

This also can result from a bearing problem. You’re going to have to open it up to do a careful inspection not only for damaged or broken parts but also why they broke, sounds like this has had problems from the start.
