The aim of the new
column is to share some secrets that I have picked up working professionally on Japanese motorcycles during the
70's and early 80's. Working on bikes at home on your own, sometimes at night, can often be a love-hate thing.
When things go wrong we often feel like selling all our bikes and finding a new hobby. Fortunately this sort of thing doesn't last and is soon
There are however, easy ways to do things that can seem to be very awkward at the time.
My first tip is to not believe everything you read in the non-genuine workshop manual.
A classic example of this is as follows:
Clutch Hub Removal Made Easy
Figure 1 shows a diagram of the WRONG way to hold a clutch centre, drum or hub for shaft nut removal.
These nuts have a lock washer and in some cases a dished pressure washer as well.
Once the clutch plates are removed the drum spins freely. The figure 1 is from a Haynes book and take it from me, this method is fraught with danger.
One slip up and the lever changes angle and breaks out a clutch finger from the clutch basket!
Figure 2 shows a typical Japanese clutch basket showing the delicate fingers.
The primary drive gear is integral with it, and it also has a cush hub built-in. These little guys are expensive and breaking one will really ruin your weekend.
There is an Easier Way!
Before you remove the engine from the frame, drain all oils, take off the clutch cover and your final drive sprocket cover. Leave the rear drive chain on and remove the clutch plates.
Select your bike's highest gear (top). Now choose the correct sized socket with a short extension and T -Bar.
After the lock-washer has been bent back you simply put one foot on the back brake pedal and undo the nut.
The rear brake stops it from turning. The final drive sprocket nut can also be undone the same way.
Finally, if you have accidentally broken a finger and there are none available at any price, breaking out a finger diagonally opposite is not out of the question. The balance
will be restored and ridden normally the clutch should operate OK.
