Well its taken me a couple of weeks but I've managed to build the hybrid box out of the two MT75s. I'm going to write it all up with pictures and put it on my website but I'll probably make it available as a word document via e-mail if anyone else wants/needs to do one, it proved to be not major league difficult in the end.

Not much of an update really and I still haven't got round to updating my webshite, maybe tonight . Anyway during a spare hour today while waiting for parts to arrive I was looking at the Dragon and I think I have found me some good news . Due to the bellhousing of the MT75 being slightly narrower than the type 9 I can lower the engine by 50mm in the chassis, it will mean altering the sump but hey ho. It also means I can move the power unit back by about 75mm which will give more room at the front as well as improving the weight distribution. Downside of this revelation is that I have to cut off my beautifully fabricated engine mounting pads and remake them .

Webshite partially updated, pictures to follow plus a blow by blow of how to build the hybrid MT75 XR4X4/RWD V6 box.

Davey,

Your hybrid box sounds really complicated, I will sit down with a clear head and read that one.

Cheers Ginge

OOoooo..

SierraShack usualy gets a bad wrap in all the circles I frequent..


Have you built the box just using the V6 front casing? I hope you have pulled the input shaft and swapped it for the V6 input shaft or your going to be cursing yourself.

Just read your build, Glad to see you did the shaft..

But the flex plate bolts may not hold up, if they are the same as the ones on my 24V's then the head is quite thin as it has little mass unlike a large flywheel.

Sierrashack did me what I consider to be a good deal, communication was loads better than some of the companies I regularly deal with and he volunteered the partial refund and gave me three options. OK so I could have possibly bought a 4X4 box cheaper and a DOHC box cheaper but not from the same source and if it was from a private buyer they would almost certainly want a personal collection "due to size/weight". I consider the deal I got to be fair and just, both gearboxes are in good condition, were well packaged and delivered to my door in a reasonable timescale. 'nuff said? I think so.

Ginge, the hybrid conversion is not too difficult if you're conversant with gearbox overhaul, don't forget I qualified as a light vehicle mechanic nearly thirty years ago when mechanics did overhaul gearboxes rather than just replacing them, we also replaced alternator regulators etc rather than just swapping out the entire unit .

Anyway, as gearbox work goes its a piece of wee wee . I will try ot get the blow by blow hybrid build procedure done soon but I have so many jobs to do and next Thursday we roll for Goodwood Festival of Speed till following Monday, can't wait

Flex plate bolts should be fine, they're high tensile and as for mass have you weighed a torque converter for a Cosworth V6? I have them tightened to the 65NM torque as quoted by Autodata for the XR4X4i 2.9 and they're fine.
