Transmission band springs

Post by T. R. Quick » Sat Aug 12, 2023 8:47 am

Are there shorter tension springs that I could use to get more life from the band linings, specifically the low speed ?

All I can tell you is if you're using Kevlar they require longer springs.

Short or older band springs will not separate the bands from the drum after application and will promote lining where from not being released from the spring tension. And if the band adjustment nut is loose thinking that the band will release will probably promote the adjustment nut and lock washer to loosen and fall into the transmission and just promote engine problems. Using the new band springs with a greater release tension will promote better band adjustment on the linings.

Tom, I'm a bit puzzled by your question. If your band springs are not allowing you to adjust the bands any further, are they coilbound? If so, the band linings/drums are well worn. Further adjustment may well result in the rivets coming into contact with the drum and scoring it.
