EXAMPLE – Fig. 51
First measurement at A: 0,10 mm (.004″)
Second measurement at B: 0,08 mm (.003″)
Subtract 0,10 mm from 0,23 mm which leaves 0/13 mm (.005″). Select a seal with red tag, 0,122 mm (.0048″) thick (average value)
Fit one seal of the same thickness to each liner and bend castellation (D) into recess (G).
Insert the liners so that the base seal colour tags are visible (spaced as shown in the sketch). (Fig. 52)
Fig. 52
Positions 1, 2, 3, or 4.
Check the protrusion of each liner in relation to the cylinder block. If necessary, change the thickness of the seals in
order to position the liners so that:
- the difference in protrusion between any two adjacent liners do not exceed 0,04 mm (.0016″) within the permitted tolerance. (Fig. 53)
- and any differences are stepped from cylinder No. 1 to No. 3 (or 4 to 6) and vice versa.
Once the correct protrusions have been obtained, refit assemblies A, B, C, D, E, and F together, then number the liners, pistons and gudgeon pins 1 to 6 (No. 1 at flywheel end) so that they match the corresponding connecting rods. (Fig. 54)
