this is a first time for me. . Seems all those "rough tracks" have taken their toll on my bearings. .
The sp1 has had the Brake calipers removed from mounts, screen, nose and side fairings have been removed, clip ons loosened, top yoke pinch bolts and centre nut loosened. . Bike is up on the hydraulic ramp.
Thats enough for tonight, need to find me some slings to support the front end on the rafters (ive got some laid about somewhere) and erm someone who has done this before to "hold my hand"
Any volunteers ? Have got new bearings, gallons of tea and coffee plus chocolate hobnobs !
Could do with. . A selection of drifts, a suitable draw bolt and erm. . . Someone who has done this before !
OK, time to edit this now the job is done,
Alan turned up and pointed me in the right direction, back end of the bike was lashed down and with all the fairings removed, a trolley jack was placed under the engine block until the front wheel was lifted off the ramp.
Front wheel removed, front fender removed, fork retaining bolts and brake pipe securing bolts removed
The top yoke retaining nut was slackened off, the locknut, locking clip and dust seal are removed. The clip ons and top fork pinch bolts are loosened and the top yoke lifted clear.... then the forks are slid out
As you can see on the picture above, the bearings just sit over the top of the centre stem, its the outer race that is fitted snugly over the stem that needs to be tapped off with a drift. To do this its easier to put the unit into a vice to make life easier..the lower seal is normally demolished whilst removing the race (make sure you have a new one to go on)
all the dangley bits are tied together and squared away
once the race has been removed from the centre stem there are two more races to be pushed (with a drift) out of position from the headstock... the upper one is pushed out from beneath and the lower one is knocked out from above..
on the above photo you can see that a new race has been tapped into the top of the headstock, below Alan carefully knocks the lower race into position
The new bearings are greased and fitted over the steering stem then offered up to the headstock
The new upper bearings are greased, slid on and the then the whole headstock assembly is refitted and tightened down.
The bearings are tightened until resistance is felt then they are backed off slightly so that movement it free.
Then its back on with the forks, clip ons, wheels and fairings...remeber to torque everything back to the correct setting.
Many thanks again to Alan and Derek for all the help during this job
