Merlin front forks compression?

Merlin front forks compression?

Post  NDHAERO on Thu Sep 22, 2016 7:55 pm

Hi, second question for tonight. How does one test the front fork springs of a Merlin? The bellows are now somewhat old, and tatty, and the springs seem 'soft' but I am reluctant to strip the forks. So is there anyway of testing the springs? I.e. if a weight of x lb the forks should compress by y inches.

Many thanks, again,

Nicholas

The fork springs are stated to be "tri pressure" so presumably are progressive, soft at first compression, becoming harder as the compress ? must have different coil spacing along the length to achieve this ? so don't think hanging weights on them will prove much ?
there must have been a free length in uncompressed state, but there is nothing shown in the parts book or JH Goddards maintenance book to show what this might be ? short of someone having a set of new springs and measuring them I do not know how you will tell if yours are tired or not ?

JH,

Thanks for that. I have a feeling i may have to strip the forks. My Merlin was secondhand, and sold as in good condition. One look at the brakes, has shown it to be in very worn condition.....

I guess it si that time to plan the winter work, so this may be added to the jobs list.

Thanks again,

Nicholas
