Another transbrake thread, & tires

One more question-
How and how often do you adjust your band? Here is some info I found on the web:
http://www.racewithjw.com/techNotes.php
Loosen the 9/16” jamb nut tighten the bolt within 7/32” allen wrench to 72 inch pounds.
Back the adjusting screw to 3 ¾ turns. The band should be adjusted every 25 runs.

Is this what everyone is doing?

Floyd, I personally do not think the power to the solenoid will make the reaction faster. To release the brake the solenoid is de-energizing not powering up. The wire size to the solenoid depends on the length to the solenoid but generally I would say #14 would work in most cases. Shorter distance is better where you are pulling power from to the solenoid.

Michael, the procedure you describe is correct. I use 3 1/2 turns out but a quarter of a turn is not much difference. I usually adjust my band about mid season and then go through the transmission at years end. Mid season for me would be in the 60 to 80 passes range. On the transmissions I build and use I do some additional oiling holes in the drum which also helps band life and adjustment needed. Adjusting at 25 runs seems a little excessive but it depends on what shape the transmission is in with pump pressure etc.
It does not hurt to check things often.

Hope the info helps.
Rick
