I have a muncie 3 speed that did not come with the front bearing cover, What I am trying to figure out is will a muncie 4 spped cover fit, they look the same but the 4 speed does not have a seal in it like the 3 speeds... so if it does, would anyone know what seal to put in it? thanks...

The 4 spds don't use a seal. You can use the 4spd cover w/out the seal it will be fine. Those muncie 4 spd are very heavy but also heavy duty and have some gear ratios that are not found in any other transmissions. Kinda hard to find though. Hope this helps.

Hey HOT champ... thanks for the reply, the 4 sp muncie I have is the alum. one, but it fits fine, I guess you have tried using one on a three speed? It sure looks like it would puke some oil out of the cover... not sure where to even look to find a three speed muncie cover, just dont see many of them around...AJ

Our transmission man specializes in muncies and saginaws and he says that as far as he knows you cant buy aftermarket or any type of new covers with the seal in them and most of the used ones are cracked. we have had one aftermarket cover without a seal machined to accept a seal, but that was a waste as as I'm concerned becouse the ones with out the seal dont really cause a problem. Look at it this way the 4 speeds dont leak and they dont have a seal so those covers will work just fine on the 3 speeds.
Hope this helps.

The aluminum Muncie 4 speeds were designed to run without a seal for street use. The seal that was installed later by machining it in in am aluminum 4 speed really does help on a circle track application, without it, a little lube slips past every race, especially if you run any type of synthetic. The cast iron Muncie 3 speed was designed to use a seal, without it, the lube just runs right past, especially in circle track. I have not found any aftermarket sources for the cast iron Muncie 3 speed retainer, not really enough of them left for a demand. I don't advertise any extra, but give me a call tomorrow and I'll check in the shop if I can find an extra one in the cores. Hope this helps -Bob or Mick 920-528-7090 www.mrracingequipment.com
