Back on the road

Post by hdawson »

Hi all.
On the road again and loving it. :D
Summer in Melbourne is ace.
Just a small issue with my front suspension.
I have plenty of spring noise(rattle over bumps) and I'm wondering if this typical or do I need to replace or pack them out somehow?
Cheers all.
Hadrian.

Bliss! So jealous, my bike is in bits and it's freezing cold here in Blighty... ;)

There are three rubber buffers on each fork leg that are supposed to stop the jangling. They could either be missing, or possibly they've just bunched up at one end. Space them out again and all should be OK...

Thanks Clanger.
How do I access these?
I would love a service manual as all I have is an old photocopy of the 1951 maintenance manual which is pretty brief.
Is there any publication which is more comprehensive?
Cheers, Hadrian.

If you drop the forks off the bike, lift off the black spring cover and you'll see them between the spring and the fork.

You can get an electronic copy of the service manual right here:

http://archives.jampot.dk/book/Workshop ... CHABLE.pdf (1957-1964)

PS: Have a look elsewhere on that site, they have all the info you could possibly need! :)

When you drop the fork legs you will see the spacers, they look like short lengths of Bicycle inner
Tube, just spread them out along the fork stantion they stop the spring rattling against the leg, could be this is what your hearing. Don't forget to tie the fork rod when removing the fork Top nut or it will drop
Down inside the leg, hope this helps.

Don't spoil the fun of going fishing with a length of copper wire, we've all had to do it some time or other!

Hours of amusement in the shed trying to get those damper rods back up.

Its easy, turn the bike upside down and the rods will pop out.

No, just a bit of thick(2.5mm)copper wire mains cable. simple loop and you cant help but fish it out.

No need to go fishing with wire! I use a length of 3/8 in bar drilled and tapped 5/16 BSC for 1/2 in or so one end, put it down the Stanton, screw it on to the end of the damper rod, and hey presto, up it comes. Works every time. Andy

Hi

Why bother fishing or drilling and threading a bar - (unless of course that's your thing :) )

One of those telescopic magnets is more than man enough to pull up the damper rods.

Except when it's freezing cold and the dampers rods are stuck fast due to the oil viscosity. Normally the telescopic magnet trick works like a charm, but this winter it didn't for me (even with a strong magnet).

However, a length of fuel hose worked perfectly: just push it onto the threads, then pull...
