Well, I have a older restored 8-98 now, and my reading mentions the "freewheeling" transmission. I also have a 1931 Hupmobile 6 that is awaiting restoration, and has a freewheeling transmission. What is freewheeling? I think I know, but I am unsure, having never driven one before. Can anyone shed some light on it for me, and explain the operation? Thanks... Lee Davis

The freeing aspect is when you are driving down the road and let your foot from the accelerator, the transmission disengages so that there is no back pressure from the engine, once you step back on the gas it engages and off you go. There should be some sort of lever to engage or disengage this option. I am not exactly sure ,but I think there is a one way clutch mechanisum. I have only driven a few cars with this option. The first time was interesting.

Can't speak for how the Hupp system worked, but the Auburn free-wheeling unit has a fairly large spring device that is coiled in such a way that if you are putting power to the wheels the spring tightens up around a hub that transmitts the power. If on the other hand you are coasting and the wheels are trying to drive the engine, the spring unwinds and looses contact with the internal hub. This prevents the wheels from driving the engine. Obviously this can be somewhat dangerous in certain conditions where engine braking is needed, so there is a lever that locks the free-wheeling feature out and a plunger that does the same when the main transmission is shifted to reverse. Primary reason for this feature on an Auburn was to ease the shifting of the 2-speed axles when the car is in motion. The 2-speed shift was accomplished with a dog clutch, so it was either in high or low range.

Well, I appreciate the information. There is a short lever just down in front of the seat (over the transmission), and I assume this is the lever that engages/disengages the feature. On my Hupmobile, there is a button on the top of the gear shift knob that actuates a metal rod running down the gear lever. I would assume that this is the same disengage linkage in the Hupmobile fashion. It is all a little clearer now. Thanks! Lee Davis

INFO IN OTHER POSTS IS CORRECT IN ADDITION A COUPLE OF THINGS.
FREE WHEELING IS GOOD BECAUSE CARS SO EQUIPPED HAD LARGER BRAKES TO COMPENSATE FOR LACK OF ENGINE BRAKING, ALSO GREAT FOR TOWING CAR BECAUSE DISENGAGING KEEPS BOTH TRANNY AND ENGINE FROM TURNING WITH DIRVE WHEELS. IN DIVING CAR IT IS NOT WORTH A DAMN, CAR JERKS EVERY TIME IT ENGAGES AND DISENGAGES, AND IT IS ANNOYING AT BEST. I HAD A 32 SPEEDSTER WITH FREE WHEELING AND AS I SAID THE BEST THING ABOUT IT WAS THAT YOU JUST DISENGAGED IT PUT CAR ON DOLLY TYPE HAULER AND IT TOWED WONDERFULLY.

FORGOT TO MENTION HOW TO OPERATE.
AS I RECALL BEST ACCOMPLISHED AT VERY LOW SPEED CLUTCH IN MOVE LEVER. WHEN FREEWHEELING IS ENGAGED YOU HAVE NO REVERSE GEAR,( ANOTHER THING THAT KEEPS MOST PEOPLE FROM USING)
