Dude Is That Your Jerico Transmission Over There In The Weeds???

Our team purchased one of the many used Howe ASA cars that had been raced down in Florida a few years ago.  It had already been converted from roundy round to both way action.  Overall, the car was in good shape, had a few leaks, but could be made race ready for much less money than a new one.  During the intial inspection of the underside, we noticed a loose 3/4"  bolt, where transmission bolted up to the aluminum (standard issue) Quartermaster clutch housing.  As it turned out, three of the bolts were stripped out.   It would take a lot more that a strong arm to destroy the threads on one of these bolts, so we suspected that there were other issues at play here.  A plan was implemented to develop a "root cause analysis" investgation.  In words, we decided to try and figure out what was really going on.  There is a lot of vibration going on at full speed with one of these cars, so we fabbed up a simple support bracket, for the back part of the transmission.  A "used" transmission bracket from a NASCAR team was found for sale on the internet, and we tacked together the rest with our wender, laying underneath the car.  Simple, effective, cheap, and we still have our transmission, in the vehicle, and not somewhere else.  The bolt on brackets that attached to the car frame are Allstar units, and come "ready made" with mounting holes drilled and tapped in them, from the good folks over in Coloma.  From there, it was just a matter of stitching everything together.  Helicoils were sunk in at all four corners of the clutch housing, and the box of gears was once again ready fer beating.

Some Basic Chassis Repair Work On Our Road Race Thunderbird

When the T Bird arrived in our shop, we knew she was in need of a little special attention.  The wounded chiicken was fresth from a "slide and bounce", off one of the Road America guard rails, which drove the right rear tire into the frame.  This former ASA race car is well built, but there was no choice except to replace the section of damaged frame that had been bent.  In the photo below, you can see where we took a Sazall, and a set of torches, to remove the bent  piece of 2" x 3" mild steel.  There are also a couple of welds that cracked in the crash, and we will deal with them at the tail end of the process.  Right now, our job is to set about fabricated a direct replacement frame unit, based on some simple measurements that were taken in the shop.  The right side mounted remote oil tank had to be removed, for the work to start, and is not present in the photos.
