Wotyer wanna DO , is LOOK AT the Index Plunger / SPRING . Very Carefully .
Thats wot holds it IN GEAR .
or thats the theory anyway . If you give it a good tug , and it stretches to six inches . Ooops , squash it back a bit - Itll stay in gear much better , but the change'll be a bit stiff , for a while .
Ahem . Have a GOOD GLARE at those bits . Carefully .
Id strip It and keep matched / mating components. LIKE . And see the bottom mounting hole is UNWORN . Not Oval . Perhaps REAM to fit 10 m.m. stud . IF a 10 m.m. drill bit end will start , in the hole.
the blunt end . The hole ends are bigger than 3/8 . So look atit CLOSELY . dither , prvaricate , and SECURE SECURELT as its wot hold it ALL in ALIGNMENT . And ' We All ' use dual top adjuster , one each side .
To LOCK IT STRAIGHT . Adj. Korekt . Tighten Crossbolt . THEN wind Adj up firm to see it wont shift back and pull the primary . Or it will ! .
You use a straight edge and feeler to double check chain / sprocket alignment . Carefully . Use Notepaper . Keep a RECORD . Of THINGS .
Like shims , amount lapped off .
AND
LAP THE TAPERS , with paste , on the mainshaft .
