Model T Ford Forum: Forum 2013: Question re repro low speed pedal cam

Asking this on behalf of my friend Jay who is also rebuilding a hogshead (for anyone following my earlier post, I went with pins not bolts on the pedal shafts Jay chose pins for the pedals and a bolt for the low-speed cam).

In any event, the question has risen is there enough free play in the low speed cam to properly disengage the clutch before starting to tighten the band. Photo below show his repro can and repro receiver (wrong term but the piece that bolts onto the hogshead).

My pedal with original cam and receiver has considerably more back-and-forth-before-moving-the-band. It looks like Jay's cam could be touched up easily with a grinder at the arrow to allow more backward movement of the pedal.

Is this a good idea? Is there a known problem with the repro parts that he can correct or are we worrying about nothing?

When I rebuild the cams, I use the parking brake adjustment procedure as a guide. The recommended parking brake adjustment is to have the clutch pedal move forward 1 inch when the lever is pulled full back. I figure this is where the cam should be making full contact and be just starting to move inward.

Thanks Ron. These repro parts allow the pedal to move at least 2" before climbing the cam. My old stuff allows even greater movement but with proper linkage adjustment they should work OK.
