Front spring lubrication

Here you can find more information about the lube I used Rear spring lubrication

Rear spring lubrication

The whole chassie, and all the little things that goes with it, is back from media blast and paint. Now it was time to apply the special leaf spring lubrication I have found on the internet. Leaf spring lubrication (unfortunatelly not available in english). It dries and becomes non sticky, it appears to be bitumen based.

I actually ordered the plastic inserts (polylines) but to be honest when I tried assembling it it looked like shit, especially when you are trying to make a stock "ish" resto. So I tracked down this solid, dry, bitumen based leaf spring lubrication instead. We will see how it turns out?

Springs are painted and ready for dissassembly and lubrication.

Started out with the three progressive leafs of the rear springs, to find out what actually was inside these bottles.

NOS front leaf springs, TAAA-5310-A

I got hold of a pair of NOS front 8 leaf springs from Dennis Carpenter. The only difference I could find was that the part number was painted on the top side of main leaf on the NOS, instead of stamped on the underside of #7 leaf as for the original. However the original #7 is in good condition so I consider to makw a switch to keep the stamped partnumber and FoMoCo logo.

Rear spring washers

 Today I got some custom washers that I had ordered from a friend. They where made slightly thicker then I needed and tomorrow I will grind them down in a surface grinder to the exact dimension i need at all the 6 attachment points for the rear springs. Pictures below shows my intention.

Reaming new rear spring eye bushings

Pins didn´t want to go in the new bushings that had been pressed in to the spring eyes, it felt like the hole had become slighlty oval in shape. For the first spring eye (the one in the pictures) I made a mistake and clamped the spring eye itself in the bench vice. This can effect the final result after reaming making the hole oval in shape, more than necessary. So for the rest of the spring eyes I clamped it on the spring itself where it cant effect the shape of the bushings.

Reaming new rear Y-hanger bushings

 Pins didn´t go in further than this after the new bushings had been pressed in to the Y-hangers. It felt like the hole had become slightly oval in shape.

 I was able to find and borrow a 19H7 reamer at a friends work, that is 19.000 to 19.021 according to the tolerance tables and the pins where around 18.95 so that would give me a min of 0.05 and maximum of 0.071mm in play. 

Rear main leaf spring bushing replacement

My new favourite toy, I only wish I owned it. New bushings coming into place with ease!!!

 Front and rear bushings in place, now I only need some reeming to get them to shape so that the pins will fit.

Adjusting rear springs front mounting point.

Pictures of when I am trying to adjust the worn rear spring front mounting point.

Above: Left side, rear leaf spring, inside of front spring mount. Quite worn.
Below: Same bracket as above but outside. Less wear.

Leaf spring perch modification #2

When test fitting the lower damper and axle bracket I noticed that the increase in axle diameter from stock 2.5" (Dana 44) to 3" for the ford 9", made the U-bolts a bit short. So I decided that I would take about 6-7 mm out of the thickness off the spring perches.

Leaf springs, Rear, cleaning

I decided to reuse the rear leaf spring as they performed well and didn´t look that worn, just in a little need of love and care that´s all.

The rear leaf springs was was marked with the FoMoC logo and this number: TAAH-5560-H
