M923A1 manual transmission conversion? Anyone done it??

[Doomsday]

So with the outrageous price tag on the rebuild of my MT645CR that was internally destroyed from heat and previous owner abuse, I am interested in researching a manual transmission conversion. Has anyone done it? If so, what transmission did you use and wht price range did you spend to do it?? How about driveline length and such?

Truck is an '84 M923A1.

Thanks guys

Joe

With a sufficient amount of time and money you can do just about anything. My guess is that it could be done using a hydraulic clutch and a Fuller 9 speed but unless you have the fab skills and a very good shop it would be more cost effective to replace the Allison. One of the reasons I bought the M927 is a knee that suffers from 40 odd years of clutching many different trucks.

Check with Glen (91W350) and see if he can help you with a fair price on an auto replacement transmission. I would think he can. He is a good troop. http://www.steelsoldiers.com/showth...-Salina-Kansas-a-Goodie-Hole&highlight=91w350

By the time you add up the cost of a transmission, bell housing, clutch, clutch linkage, drive shaft you will probably be at or above the cost of a rebuilt transmission. This does not include the time and material, or cost, to put this together.

With the current prices of M939 series trucks I'd say buy an ugly runner, keep the trans and part / scrap the rest. Done right the trans would be free.

I have worked it out and it can be done. But I would buy a parts truck instead.

Wreckerman, since I also own a M927, may I ask you, are you using yours commercially? If so, what for and how do you find it to be, is it a useful comm. truck? thanks
