Title: Cluch Cover Side Case Tightening
Post by: MattyQ on April 27, 2007, 09:06:59 PM
I read in a manual somewhere , that you should use a impact screw driver  to secure the outside screws of the clutch cover casing ?  As stripped as the philips screws were that i had to drill out , is there an alternative method ?

Thanks

Do not use an impact to tighten case cover screws!!!!!

"Never use an impact wrench,,,Torque wrench maybe,,4-5# foot pounds at most!First clean the screws with contact or brake parts cleaner,and the case threads too,then a dab of clear silicon will hold them in tite even at 1#foot pound! A big long wide screw driver helps?Same principle with the KTM motors allenheads too,only use hand held impact wrench on stubborn bolts and screws!:)"Never beat on cases,Use a little heat!:)

Matty, those screws were probably installed some 25-30 years ago,
that may contribute to them being on there so tight.  Don't worry much about it though,its a very common problem.  It just might be a touch of oxidation or that other white stuff that seizes our crankshafts when the bikes sit for years :(
