I have gone the double belt route after the one belt experiment kept slipping and burned out bearings from the tension.
Now I use a goodyear synchronous (like in a supercharger) and have not burned out any bearings.
My electric motor is mounted on a home made frame to my BorgWarner. Pulled out 4 main cover bolts and used larger ones to mount the frame to the transmission.
Goodyear supplies gears for the top 10 kw (3 phase) and my large gear between the transmission and shaft (which had to be machined to fit ).
My biggest problem is heat ... and Im thinking to convert up to 96 volts.
Any concurrence on 96 volts works running cooler?
There are probably better ways and head scratching has cost me lot of hair.
HAS ANYONE UTILIZED A TRANSFER CASE ?
There is a shop in Whisky Creek that has made parts for Borg Warner that is willing and has designed a transfer case for our purpose.
10 k Canadian for the first one ... less if there are more any interest ?

Wonder if you could install a tensioner pulley of some sort if you wanted to disengage the electric. But don't see why you would want to the seems the electric would work well as an alternator to charge batteries.

You'd have to be able to swap between the diesel and the electric motor on the drive shaft, otherwise the electric motor would act as a giant alternator when running the diesel and that would greatly decrease the efficiency of the diesel. If you have regen set up, it would however charge your batteries rather quickly.
Hi Matthew,
Would you plan to somehow disengage the belt to the pulleys when using your diesel motor?
