Model T Ford Forum: Forum 2009: Adjusting low speed band

I replaced my Kevlar bands and went back to cotton back in may. I have not driven much since then, probably 50 miles. The other day I adjusted the low speed band and it was working great. Went for a 20 mile ride, about 1/2 way the band was not grabbing the drum like it was for the previous 10 miles. When going through a intersection from a complete stop, it would slip about half way through the intersection. I am trying to get ready for the horseless carriage club tour tomorrow and this is bothering me a bit.
Should I just re adjust and everything should be ok?

Re adjust. I think they are getting seated. You will probably have to do this a couple of times.
Good luck.

Driving technique affects band wear greatly. The engine should be just above idle speed when you step on the low pedal, unless you are starting up a steep incline. The proper technique is a fairly swift stomp on the pedal. If you have the throttle in the right place the car gracefully moves away with very little slippage of the clutch.

If you use great amounts of RPM for every normal movement from stop you will have to adjust the band frequently. Your Model T transmission is one of the weakest parts of the car. Treat it with lots of care and it will reward you with long sevice life.

I agree with the above posts. The secret is to firmly apply or "stomp" on the low pedal while simultaneously applying throttle....do not rev up the engine and then stomp the pedal. The lower the engine speed, the more positive the engagement. You want to apply the low band at idle speed. It will give a slight lurch and try to stall, but THEN quickly add the throttle and advance the spark, and you're off. My cotton bands took about 4-5 readjustments before they seated. They were new, 35 year old cotton bands that came with my car. When it's time to replace them, I am going to replace the cam on the low band shaft and hogshead to get an even more positive engagement. Stalling out a hand-crank-only car in traffic makes learning the "Stomp-throttle-advance-go" technique mandatory!! Have fun.
