There are great many kits available off the shelf. They offer bolt together simplicity, but at a price. $500-$1000.

Here is summary of the off shelf options found on the web:

Home made, no clutch option: http://www.diyelectriccar.com/forums/showthread.php/aircooled-transmission-cut-not-cuti-32991.html using a big sprocket, like this one: http://www.electric-lemon.com/?q=node/213

After discussing with Billie at Stockornaut with aid of machine shop a more cost effective solution can be made from off the shelf components.

2009 09 16 – Crank shaft end piece back from machine shop

2009 09 26 – Bench testing completed coupler

2009 10 05 – Bench testing for final alignment

2009 10 18 – Completed coupler fitted

Motor bench test, first test of motor. following the bench test guidelines very closely:

Crank shaft and sprocket welded and mounted

Motor test with flywheel

Transmission – found intact circlip! JOY.

Transmission cleaned and input shaft repaired.

Evening at Stockornaut: Crank shaft end piece back from machine shop

Sourced a large 1.125 diameter sprocket which will be welded and sleeved with the crack shaft for very solid connection.

Will use a resurfaced flywheel (original German) and brand new OE Clutch kit.

Templates for the transmission and motor being send to metal laser cut shop for the end mounting plates fabrication.

Other component updates:

Transmission – will replace main seals and investigate loose shaft, believe should be just a Circlip – if we find a whole circlip in the bottom of case – JOY, if not… mmmm…

Drive shafts, CV joints, boots – will replace with all new pre-assembled unit from So Cal, this removes any doubt about the previous condition.

Brakes – waiting on delivery of mounting brackets for upgraded front disc brakes

Batteries racks – design modification to balance to load, plan on using basic angle iron to build frame to hold batteries in place bolted through the floor.
