Hi folks,

So, I'm planning to mount an 8" Netgain motor in my Morris Minor, as I've mentioned before (slow background project). The plan as it stands is to maintain the clutch (whilst I'm hoping that I won't need it, the car has a weak synchro on second, so if I do need to use second gear then I might want the clutch*) and transmission as it stands, and essentially 'just' switch the ICE for a motor.

I'm planning to have fabricated two mounts which replace the existing mounting towers and then have the backplate drilled so it has appropriate holes to attach to the motor.

Now, the original mounts have whacking great lumps of rubber in to, I'm assuming, reduce vibrations from the ICE. But I'm a bit unclear as to whether they also allow a tiny bit of movement to allow for movement / reduce shock in the transmission.I've had a quick look through the motor mounts thread, and the Midget project looks conceptually close to my Minor - the shots in that look like although the rubbers are still in place, they're not being used. In which case, something like this would be my plan (AKA Plan A)...



The other option is to use the original mounts and make an adaptor to go onto them...


Does plan A seem reasonable? Any suggestions folks?

(PS - Downloaded DraftSight today, which should ruin any chance of me doing my dissertation).

* I'm also hoping that while she'll probably eat clutches for breakfast, it might provide a bit of protection for the transmission from the massively increased torque from the motor compared to the old ICE.

I would use the original mounts and rubber and then fabricate the motor mounts from them to the motor.

My reasoning for this is that the tailshaft of the gearbox will also have a rubber mount and the chassis of the Minor will flex as you go over bumps and potholes. If one end of the motor gearbox assembly was rigidly fixed to the chassis then it will add loading into the assembly from chassis flex and general bumps and movement from the back end of the gearbox.

Having all the mounts on rubber will allow the motor gearbox to be protected from such movement and shock loads.

I am useing a 6.7 D&D motor do I need to use a motor mount on a vw bug this is also my first e car.

The air-cooled VW Bug does not use a motor mount. The motor and transaxle assembly are attached by 3 transaxle mounts. The motor just hangs off the transaxle, held in place by 4 bolts. While that sounds dangerous it was quite successful for 65 years.

Hiya,

Thanks for that - that makes sense. Okies, well, nicely decided - and hopefully cheaper, since I might just be able to get them to modify the existing front and back plates.
