Model T Ford Forum: Forum 2016: J-B Weld on spring leaf
Top of pagePrevious messageNext messageBottom of page Link to this message  By Tom Stephens on Sunday, February 28, 2016 - 04:13 pm:

The end of one side of my top spring has worn a rather large rut into the leaf underneath.

Do you think if I filled in this rut with J-B Weld, that would keep the rut from coming back, or would the top spring quickly wear away the J-B Weld?

I can say the shackles and perch bushings were SHOT. I am installing all NOS shackles, bushings, and upgrading the rest of the front axle parts.

It would quickly wear away.
If the blades still have enough strength, the best you can do is to round off the lower outer edges of the leafs that otherwise keeps on digging into the leaf below.
Paint them with a mix of black paint and graphite like Ford did (or buy it already mixed = slip plate paint from Tractor Supply :-) )

Hi Tom here is how I do it...


Close-up of wear caused by leaf above:



Wear ground off with an angle grinder followed by sanding disc:



Bottom of every leaf rounded off at each end to prevent future wear:



Leaves lubricated with graphite paint:



Springs going back together:

Chris has it right. There's no repairing the wear spot. All you can do is move the wear spot to another area by grinding the leaf above and keeping it lubed.

Thanks, great info!

My gouge is very deep. I guess this means I'll need another leaf.

Molybdenite a naturally occurring mineral added as flakes to grease makes a better additive then graphite for your springs. It stays slippery even after the grease burns off and actually bonds into the porosity of the iron.

These are samples of Molybdenite I mined years ago at an old tungsten mine in Calaveras Co. Ca. It's very similar to graphite in being soft and micaceous.

Chris has it right, Tom you can even go so far as grinding the bottom edge in an angle even greater than Chris was talking about based on the depth of the gouge your talking about. By doing this you are mimicking the early taper leaf type springs that rarely had these issues.

On a deep rutchie what I did was get that Teflon sping strips and line between the worst leaves and painted the rest with graffiti pain mix

Tight wadded as I am if it were me and the worn groove was deep,I would get another spring leaf.
Then do the steps above to prevent damage.

All good info. Yep, I am continuing my Classifieds search for another leaf.

I've ordered and received single leaves from the Model T Haven before. Measure and call.
