matching enginecases
« on: 07.03. 2012 14:13 »
hi chaps, i recently purchased my old a10 with the engine blown, hole in the crank case, chain case side, i was supplied with a spare half case for that side,  i came across another case a10 complete which i purchased , but when i get it  , its the wrong type as mine has the chaincase joined to the engine casing and this one has not. I am thinking my best way out is to fit the case i was supplied with in the first place it does fit together, but i have a feeling  its not just a matter of studs. any ideas anybody?      *sad2*

Hi tumbleweed , is your bike a plunger framed A10? . The plungers had a semi unit construction with the gearbox bolted directly to the back of the engine and the innerprimary chaincase attached to the crankcase the swinging arm version has the screw holes and 2 bolt holes to fit a detachable chaincase. Sounds like a plunger be careful fitting just one other crankcase ,they were fitted has a pair so you may find things just slightly out when you put the other case on and can get leaks and even worse ,check carefully if you go down that route,regards bobh

 G'day tumbleweed, how bad is the hole? You might be able to repair yours with a piece cut from the case you were supplied. There are some bloody good welders out there. At least that way all the holes and the deck will line up. Post a picture of the damaged one.
Cheers
