Cracked casing

[garry inglis]

Whent for the back brake and nothing so I thought I'd investigate and took the hub off and gearbox oil everywhere so cleans it up and could see oil coming out the crack so I've ordered a new casing and will rebuild it and get this welded up

bad luck matey... great images though. That crack hardly looks large enough to leak so much oil does it ... What caused the crack do you think ..? was it the stud being overtightened or pressing the bearing in ?

It must be but it's done 3000 miles no problems the one in the casing I think I done mounting up my decking

While the engine out I've fitted grub screws into the offset cones to stop them turning

have you got someone sorted to weld your case up garry, i would recomend tony at ajs in hull, he did all the welding on my rotax does a first class job

[garry inglis]

Yes I have Steve but if it doesn't come off I'll let you no thanks

offset cones great ide.....never thought about them gradually turning though . I did think of fitting some to my special but it looks like you only achieve 3mm offset which doesn't sound like much. Did you find them worth fitting ?

[garry inglis]

Yes definitely otherwise you have to By an aftermarket reed and manifold like mb £160

New casing turned up from Cardiff scooters there getting hard to get hold of now started by cleaning it up then fit new rear bearing and oil seal then new ferodo shoes will add pictures as I build it up

Started on matching transfer ports to spigot and casing matched 2mm base packer to barrel transfer ports then fit to casing
