Yam Mono Rear Spring Removal

Featured Replies

I am trying to remove the rear spring of a R model shock with the remote reservoir.

When I unscrew the preload retaining collar it will not slide off as it catches on the damping adjuster.

What do I need to do???

Well I've searched the workshop manual and replacing a spring does not get mentioned.

What is mentioned though is the Damper Rod or Oil Seal, if damaged - replace the whole unit!

It does not say 'why' (ie. spares unavailable etc) therefore this leads me to think it's none-dismantle-able....

...... also the manual goes into great depth about using the correct method for disposing of the shock !!!

Someone out there MUST have tried this before.

I think the only way you can remove the spring is to undo the base of the assembly from the damper rod (assuming the damper rod is threaded)

The problem is the limited amount of room to get a fix on the rod due to the reservoir hose joint preventing the spring from being moved very far.

Ive tried loads of times in the past and even had a "proper motorcycle mechanic" have a look and we have had no success.

You could try ringing Nigel Birkett - at least you would find out for sure if they can be dismantled.

Did anyone find an answer to this question, because I want to do the same thing?

Cheers
