Hurst Shifters for Muncie M-21

SnThetcOil · #1 02-21-2005, 06:38 AM

Hello gang. Does anyone know of a book on the market that shows how to work on the shift linkage for a Muncie M-21 4-speed? The linkage in my car just isn't shifting correctly and sometimes it actually gets stuck in gear. The folks at the local transmission shops haven't seen a Muncie 4-speed in years, so they are of no help. <font color="blue"> </font>

Ship the shifter to Hurst and the can rebuild it for you.

If you can get someone to help you, put the car up on a lift and have someone shift through the gears while you watch the rods from below to see if there's any noticable binding, or excessive slop due to worn bushings. Newer Hurst shifters use nylon rod bushings, while older designs used more durable metal ones. Either way they're probably well worn by now and due for a replacement and both styles are readily available. While it's not as good as sending the whole unit out for a professional rebuilding, new bushings and a proper adjustment may get you by for now. Also, keep it well lubed with some lithium grease...or some Amsoil product in your case.

Can you share some more info about your Yenko Camaro with us? Pics, description, selling dealer? I guess we can assume it's a 4 speed. Where ya from Steve?

Does Hurst remold the rubber on the levers? I had two redone by them (Through Year One) One needed the rubber replaced, and they did not do it. Year One ended up no-charging for the rebuild as a result.

The rubbger was like new on other shifter, so I did not expect Hurst to redo it.
