Hi all,

extreme long shot but I'm trying to find the engineering drawings that shows the dimensions and details of the main engine case... Any idea if these even exist?

Well that's a start, so next step is where can I get the details for the hub bearing area?

Believe Scootopia has them but if that doesn't work out who or where else?

I'm guessing the guys who are currently producing casings - Casa, Uni, GT etc will all have their drawings but it's whether they'll share them - depends what you have in mind.

Maybe you should have asked if there were any in the public domain?

Perhaps if you approached one of them with a proposal they might be willing to help if it wasn't against their commercial interests?

Rich Taylor is now producing casings and he might be worth a call

Cheers for all the replies, will contact those listed .

ZERO commercial use, I'm trying to save a case that's had significant damage around the hub bearing bore and to assist the remachine I'm wondering if the drawing shows datums or other measurements to help me find the centre.

To find the centre line of the hub bearing you first need the the centre line for the case. The case centre line is between the rear side case dowel and the forward-most exhaust stud. Clocking off the centre of the gearbox lay shaft bearing, the rear axle centre line is 69.31mm aft. Hope that helps
