Installing Currie Third Member Unit: Final Steps

Bookmark and Share

In a recent post we took you inside Currie’s facilities to show how the professionals there installed a Currie third member unit. We were invited to take a trip into the shop with our camera to get a first-hand look at how to assemble a brand-new Ford-style, but Currie-built, third member gear case. We took a close look at assembling pinion support and gears plus installing the carrier unit.  Now take a look at the final steps of how it was done. 

 

Before running the pattern on the gears, they paint white marking compound onto a small section of the ring gear teeth, then they put grease onto most of the remaining teeth of the ring gear.

This allows the grease to make a footprint onto the white marking compound when the pattern is run.

Once again, the pros here at Currie nail it on the first try, so no additional tuning is necessary.

Lastly, they remove the set-up yoke, grease the new yoke and install it. To keep the pinion nut tight, an impact gun is used.

The completed unit is lifted off the bench and set onto a painting cart where they finish painting it to protect the nodular iron from the elements.

Then it’s bagged, sealed and packaged in a shipping crate to wait for the big brown truck to deliver it to its new home.
