Ahhh, the simplicity of gearbox overhauls. During the years I raced my Lotus 61 formula Ford, I also built gearboxes for fellow competitors. Most common was replacing the original Hewland gearbox case (type 1 VW case) with the VW "Rhino" case. It could easily handle over 200hp developed by the Lotus twin cam/Cosworth BD series engines. The first Rhino case I did, I wrote down all the setup specs for my milling machine, and afterward could machine a Rhino case into a Hewland "Mark series" case in a couple hours. Rather than spend thousands for all the authorized Hewland tools used in setup, I made my own. I used an old Mark series case with the side cut out to set up the bearing carrier (what you call the intermediate plate). I had 27 Hewland gearsets, so I set up my box uniquely for every track. (I could do a gear change in 20 minutes). In a perfect world, 1st gear was set for the slowest corner, and 4th gear to redline a couple hundred yards before the brake point on the longest straight. 1,000 rpm drop 1st to 2nd, 750 rpm drop 2nd to 3rd and 500 rpm drop 3rd to 4th. (1st gear for Sears Point was a stump puller, and 1st gear for Willow Springs... the car would do 83 mph in 1st gear). Once you know WHAT you're adjusting regarding pinion end play/backlash, and the other critical measurements, gearboxes are really simple things. Knowing what you're setting up with the bearing carrier, my boxes would shift like drawing a steak knife thru warm butter. I made lots of $$$ on the side for something really simple. BTW, I liked your homemade tolerance tools!!

That was a lot of work. No wonder it is expensive to have them rebuilt. Nice job explaining everything that went into getting it right.

Whew, that's got to feel good having that done. Well done, great series.

Hey Tom- I just noticed some aftermarket 356 Drop Spindles on Craigslist for $300. Not sure if you’re in the market. Currently in the parts for sale section of the North Bay Craigslist. “Porsche 356 Drop Spindles” . No affiliation Just thought that maybe you might be interested.

Hi Tom, I know it's been ten months on this video, I viewed it many times especially the part where you install the nose cone since I am about to do that, the hockey stick has to fit in the gear selectors, do all 3 pieces have to be aligned in the neutral position so I can insert the thing in. hope I'm explaining it right.

Way to go.. I have a 72t with rice crispness between 2 and 3rd... not looking forward to this ... another tedious sequence requiring all of my attention and limited smarts..

Is it me- or does it seem that 356s are much more complicated than the 901 cars….🤔
