Hi,
Although I built my Ulster replica some years ago I have never had a starter motor so to cover the opening at the top of the gearbox / bell-housing I have a later Ruby type sheet steel cover.
I have now collected most of the parts to add a starter motor but the cut-out in the front bulkhead which just clears the Ruby style cover won't allow the cast alloy starter motor mounting cover to fit as when I try to locate it over the flywheel there isn't enough vertical clearance.
I am removing the engine and gearbox today and will obviously need to cut away some more of the bulkhead whilst this is out but it's very difficult to judge how much is needed and I'm also concerned that the throttle cross-shaft passes over this area which restricts how much could be easily cut away.
At the moment there is probably 20 - 25 mm of the sloping section of the bulkhead left above the cut-out (ie. the part of the bulkhead through which the pedal arms pass). I could relatively easily cut this away up to the point where the sloping part joins the vertical face of the bulkhead which then runs up behind the fuel tank but is this going to be enough?
Not sure how anyone can advise me but I'm very reluctant to have to repeatedly remove the engine / gearbox just to see if it's enough.
Any advice?
John.
