How to treat the new Front Leaf Spring
Got myself a new Front Leaf Spring and it says "Show Quality"
Its assembled and with center spring bolt and bronze shackle bushings. So far, so good. But - This is raw steel. Now how should i treat it prior to mounting it into the car? Demount the center spring bolt again and paint each leaf ??? Please advise Thank you Christoph |

Re: How to treat the new Front Leaf Spring
Un bolt everything. On the surfaces that will touch each other, spray with "Slip Plate". After it's dry, re-assemble and then paint the assembled spring with a good quality black chassis paint. I used Rustoleum Professional spray paint. Not sure what you would have available there.

Re: How to treat the new Front Leaf Spring
Not to be a stick in the mud but wouldn't it be better to paint each leaf before applying slip plate?
Sure where the leafs rub the paint may flake off but everywhere it doesnt rub would be coated with paint to prevent rust and then with the 2nd preventative of rust the slip plate would be there. what killed alot of the leafs i see is water getting trapped between each leaf and causing pits. If its painted and greasy it should outlast you.

Re: How to treat the new Front Leaf Spring
Either way, just make sure to get the slip plate (or other lubricant) in between each leaf.

That will increase the spring rate to a point where you think you have no springs. "Un bolt everything. On the surfaces that will touch each other, spray with "Slip Plate". After it's dry, re-assemble and then paint the assembled spring with a good quality black chassis paint. I used Rustoleum Professional spray paint. Not sure what you would have available there." About the only way to improve on that would be, have the leaves Parkerized before spraying with Slip Plate. If you want the "stock look" just go with the paint. If you want to keep water out, wrap the spring with black electrical tape from the eye to the U-bolt area. If you want the real fancy look, get some of the old leather spring covers. |

By saying "think you have no springs" do you mean the car will sit lower or "bottom out" on hard bumps or be bouncy as can be? I do know when i had to replace the shocks on my modern pickup with rear leafs i bounced the back-end with no shocks attached and i didn't think it would ever stop bouncing!

Re: How to treat the new Front Leaf Spring
To prep a spring for use I first sandblast each leaf then grind any wear pockets smooth. I then grind a bevel on the bottom of each leaf to help prevent it wearing another pocket in the next leaf under it.
I then paint each leaf, coat the bottom of each leaf with Mystik JT-6 and sprinkle graphite on the grease. I then assemble the pack and wrap it with spring covers. This is my friend's rear spring, which he had powdercoated. |

Re: How to treat the new Front Leaf Spring
When I did my springs, I sand blasted to remove corrosion. Skirfed the mating surfaces. Then chamfered the ends where they slide over the leaf below. Then applied a dry graphite lube, Lubribond 122, on all rubbing surfaces. Then assembled. Finally, remove excess lube from exposed surfaces with my favourite paint prep solvent and paint assembled.

Re: How to treat the new Front Leaf Spring
Thank you for your suggestions !
FB is the place to be.... No Slip-Plate available over here. Will use some othe special grease http://www.mike-sander.de/ which (as well) protects against corrosion. Will use some Graphite with that. Than assamble again. Than some paint (just outside). Than more grease. Than "Fettband" which is a warp-arround http://mike.british-cars.de/Info_Fettband.htm This keeps grease inside and it keeps water and dirt outside .... As this wont look original, i will use the original spring-covers from the vendors to hide this. Sounds like lots of work, but i do not want do that again (within the next 85 years ) Thank you again Best regards Christoph |
