Model T Ford Forum: Forum 2015: Question - new band return springs/old springs
Top of pagePrevious messageNext messageBottom of page Link to this message  By Tyrone Thomas - Topeka KS on Sunday, October 18, 2015 - 11:05 am:

Replacing my tranny bands, I ordered new return springs. The springs that are in the car have been there since at least the 60's with few (trouble free) driving hours since. They seem to still have good tension. The new springs I received are a good 1/4 inch plus longer than what I pulled out and a whole lot stiffer. I decided to reinstall the old springs rather than fight the longer springs.

Question. Comparing the new to old springs, are the new springs made longer/stiffer or are my old springs worn out.

Agee with Will. I did the same as you, Tyrone. Reused the old springs after comparing both. I suspect the new ones are longer and stiffer than Ford NOS.

Ty,

Yes the new springs are longer and if you try installing them out of the box you usually get to cussing...

Old springs may have somewhat softened over time, but no big deal...you let off the pedal do they return the pedal without drag on the drum? If so, good to go with the olds.

Here's a 'hack' I've learned for those long springs...put them in a vice and collapse them full and then 1/4 turn more...you take them out of the vice they are 'just right'

I have installed the new springs right out of the package and they worked fine without any changes to them.

I could see the ease of placing new springs if you are working on a bench. I was working in-car which I see could be a real headache to install new springs.

I thought the springs that are being made now are longer than the originals for a reason.
The reason being is to give more band release from the drums.
When using Kevlar if the bands drag in the drums it causes excess heat and possible drum failure.

That use to be the selling point in the catalogs.

Like Mark, I had no problems with the new springs.

John K is correct. They are listed as heavy duty and required equipment to ensure band release if you use Kevlar.

Some of those repro springs are too long. You should be able to start a nut with the spring in place, with little difficulty.

What is the actual length of NOS band springs ?..... and the ft/lb value at a designated compression ?? ... I've had no problem with the "longer" springs since my size 13's easily mash pedal. LOL

Old springs will be shorter than new, just like humans "shrink" with age...... height that is.....LOL

I don't know about the rest of you guys but a longer spring means that I can't get that last adjustment or so out of my Scandanavia's because the longer spring is compressed and won't let me go any further.

All very well and good Ed, but..... what would be the NOS measurements of the band springs ??????? I'm sure used springs will be shorter than NOS new.
I've had no problem with the new production band springs, not the ones with the gold tone finish.
