Finding the right drive shaft

Due to the electric converison the original driveshaft can’t be used. It has a bracket that attaches to the original engine. So I had to find out which one would fit my Elise. A visit to a workshop where they had the PG Elektrus in for repair solved my problem.

The drive shaft in the PG Elektrus still had the label with partnumber on it. It showed B120D4004F which is correct for an Elise CR. I now know why the drive shafton my car failed, it is designed to cope with 136 BHP and 160Nm (118lb ft) instead of the 200 BHP and 225Nm (165 lb ft) of the AC-150.

I 0rdered the drive shaft en found out that my car had an early model A120D4004F drive shaft. the new one B120D4004F has different CV joints.

Broken RH driveshaft

Last night I hit a speed bump and broke the RH driveshaft, i was putting my foot down quite hard in second gear. The back wheels did spin a little.

I asked the dealer which driveshaft would fit my Elise, they quoted the original driveshaft for an 2009 111R at €946,- with partnumber A120D0018F (#2).
