I have rebuilt the clutch centre with new rubbers. I have made a tool with a 20mm Square tube attached to a steel plate. Used the tool for another engine about 15 years ago and could handle it myself with one hand and put the rubbers in with the other. This time I had to put another tube as an extension, about the same length as the Square one on the tool. Barely succeded to put the rubbers in the centre but only with an extra pair of hands.. Even bent the Square tube a bit. I tested with two different batches of the rubbers with the same result. Should I be worried?

Hi Lars,

this is the scrap center I use for the rubber exchange.

If you do not put the bigger rubbers in first, it is almost impossible.

As Allan stated, usually the spider wears as well, but IME the steel parts last longer than the rubbers. The rubbers can be exchanged once or twice.

Again, good luck.

The easiest way to put the rubbers in I’ve found is to:

Have a spare clutch steel plate, weld a bar to it

Have an old clutch centre (the bit that fits on the taper shaft)

Grind two flats on the centre so it can be held in a vice. Mount the Cush hub with one plate removed (if your using through bolts then put the bolts through and nuts on so the back is
Held on.

Drop one set of rubbers in. You’ll have more room for compressing if you put the large ones in first.

Slide the modified clutch plate over the Cush drive and pull the bar so that tension is applied the the rubbers. Then drop the small rubbers in place.

The unit will hold itself together enough so you can get the outer plate bolted into place.

If there’s any wear on those outer plates, either replace them or flatten them until all impressions have been removed..
However if you find that these are worn it’s been my
Experience to cut your losses and buy a complete centre. All the parts on these wear, so if something is worn then most likely everything else is too.

Allen G beat me to it...that is exactly how I was taught to replace the clutch rubbers.
