Hey,

I managed to pick up a 6 speed mt75 R&D dog-box.

Just wondering if anyone knows which bellhousing is required? I was hoping to use the T5 bell housing but unfortunately, the input shaft is ~10mm shorter than the T5 gearbox so an adapter plate may be out of the question.

Cheers

 

the MT 75 gearbox doesn't have a seperate bellhousing its part of the casing, all the R&D MT75 gearboxes iv'e seen use the standard front casing
are you sure its an MT75 box?

Hey,

yeah it’s defiantly a mt75, but has a r&d cast center section

i think the v6 gearboxes often had separate bell housings, but not suitable for a YB

 

The MT75 never had a separate bell housing, so also not for the V6 or DOHC engines.

Okay, its based on a mt75 is probably a better way to describe, much the same as this gearbox on eBay (yet the 6 speed version), I've also seen lots of R&D mt75's use the integral bell housing

no worries, ill likely do what i can to retain the T5 bell housing as id prefer to have that as a easy swap backup. I think it may be possible but need the engine together to start measuring.

Cheers

 

Mitchell & Cotts remanufactured the Mt75 with a separate bellhousing for the likes of Morgan.
