front fork slider 021399 - looking for replacement

Post by asterysk_usa »

My 1954 18S right fork slider is damaged (has a hole) it is part number 021399 ("slider fork with cap")

Any suggestions on how I could get a replacement

1954 AJS 18S Cyprus export (frame decode says 1954 but many components match a 1955).

You may find used part at AMC classic spares but get the part number correct its 021977 for 1955 fork

There's something wrong here, those aren't 012977, they are from pre '55 with double lugs for 2 stays. Are your stantions 1 1/8" or 1 1/4"?

They are 1-1/8" stanchions which I presume indicates 1954 which is part number 021399

however, comparing the bottom of each slider I can see they are different , can anyone assist with determining which is a 021399 and what the other one is ? thx

Hi

I wouldn't consider trying to repair that damage - ascertain the part number of the good slider and source a matching replacement.

Struggling to see how that damage even occurred :?

The broken slider is correct the other has had welding work around the mudguard fixing. If you want to upgrade to 1 1/4 you will need top and bottom fork crown fork top bolts the stanchions fork springs and if i remember correctly when i did it you will need the spring covers and the bit that screws into the slider. Obviously you need the sliders and caps. I would not bother. (I was ugrading my forks to coe with a double adult sidecar)

Are they both the same model? The one on the left looks wider and longer so is it a different year or spec?
