O-ring chains have sealed, life-lubed link studs and bushes. However, these chains need lubricating at regular intervals to protect metal parts of the chain and the o-rings.
Lubrication also serves to keep the o-rings soft and pliable to ensure the maximum sealing efficiency.
Using a brush, apply a thin protective layer of high-density gearbox oil along the entire length of the chain both inside and outside (sec. 3 - 2, Fuel, lubricants and other fluids).

Inspection of the gear selector drum
Use a gauge to measure the clearance between fork pin and the slot on the
selector drum.
If the service limit is exceeded, determine which part must be replaced by
comparing these dimensions with those of new
components (sect. 3 - 1.1, Gearbox).
Also check the wear on the drum support pin ...
