1. General
If only the lubricating quill must be removed, with water guide jacket (lower part) in
situ, then bush 8, flanges 9 and 9a may remain in place. Therefore, the cylinder
cooling water must not be drained.
In order to remove a water guide jacket (lower part) 4 or cylinder liner 1 however, all
lubricating quills and bushes must be dismantled, whereby the cylinder cooling
water must be drained on the relevant cylinder (see 2708−1 ’Removal of cylin-
der cover’).
