The 1FZ has officially joined the 6 speed RA60 transmission. The mounting flange from the old A442 bellhousing was cut and removed, then TIG welded directly to the RA60 bellhousing. A few redundant steel braces will help support the weld... cast aluminum is cast aluminum, after the TIG is done, it can only be so strong.

Centering the transmission to the engine was a slight challenge due to the fact that the RA60 uses no pilot bearing. A 3.5" long sleeve was machined and used in much the same way that a clutch alignment tool is used. The sleeve slides over the transmission's input shaft, and then slides into the pilot bearing hole in the crankshaft as the transmission is set into place against the back of the engine.

Now on to machining the flywheel and adapting the Orion....

No pilot bearing? From your post, I can't tell what supports the input shaft???
 
Yup... no pilot bearing is used. Just like the old front drive cable clutch VW's. The main shaft is very long and gear reduction is done on the output shaft side. All support is internal to the transmission. Nothing explains(??) it better than the picture of the shafts....

Wow. You definetely have that Jowett Motor Co. blood in you.
 
did you just machine your own flywheel?

very cool
 
Will you be putting that engine on an engine dyno before you install it for comparison to the stock numbers?
 
Nearly complete, it now weighs 40lbs, a work of art IMO. One should now be able to see how the larger starter ring gear for the 1FZ has been incorporated into the flywheel design. The Tacoma flywheel is on right, note the smaller ring gear. Flywheel faces are the same.

Backside might have a few more pounds shaved off when cleaning up.
