Locate cylinder liners in the block without sealing
rings. Measure liner height, dimension A as illus-
trated. The measurement is done at four diametrically
opposed points on each cylinder. Check that the sup-
port surface is not damaged when resetting the dial
indicator. The check is made with dial indicator 998
9876 and holder 999 2479. The height should be
0.06–0.11, but the difference between two close lin-
ers must not exceed 0.02 mm. Mark the liners so
that they have the same position when installed.
