IMPORTANT
If the old oil seal lip has marked the crankshaft
(flywheel end), a washer 1.5 mm (.059") thick must
be inserted between the new oil seal and the tool.
This will push the seal in further on the shaft and
give the lip an unworn bearing surface when in
position.
A. Normal position of oil seal using Tool Mot. 789.
B. Position the oil seal using Tool Mot. 787 and 1.5
mm washer (giving offset to lip on overhaul).
