1. General
The removal of the piston rod gland (hereafter called gland) can be carried out in
two different ways, i.e. removing the gland together with the piston (variant 1) or
removing the gland downwards into the crankcase leaving the piston in situ and
using dismantling device 94344 (variant 2).
On every piston overhaul, the gland must also be dismantled and inspected. Ex-
cessively worn or damaged parts are to be replaced.
It is important that the gland be in perfect condition when assembled. A possible
earlier than planned inspection of the gland with a piston in situ can only be carried
out under difficult conditions and with the help of dismantling device 94344.
