Message to self, reminder of torquing up Primary Drive Gear Bolt, a must in my case if it isn’t done straight away.
The Clutch Primary Gear was mounted on the Mainshaft together with its associated Spacers/Collars, Bearings & Oil Seal, please see http://www.nsr250.net/forums/viewtopic.php?t=15439&highlight= for more detail.
Thank goodness for Cardboard it has so many uses!
Slight application of Blue Hylomar to RH Crankcase Cover (love the stuff, been using it since the 60s!!! well it was ok for Rolls Royce so who am I to argue, ok it may have been used on Jet Engines LOL).
The water pump wasn’t removed as it was rebuilt very recently.
A new Sump Washer & Crankcase Cover Gasket was fitted, the Kick Starter & Crankcase Cover to Clutch Primary Gear Oil Seals were left as is, as they had been replaced very recently.
A slight manipulation of the Water Pump Impeller/Crankshaft was required to help mesh the Gears whilst trying to get the Crankcase Cover home before bolting everything up.
