from the joint faces. If any machining or cylinder block face has taken place, it is essential that all swarf is removed before assembly of the engine takes place.

Measurement of the cylinder liners should be made in conjunction with the data given in Section 1.4.1.0., noting the different diameters of size classes and the two engines. Measuring a cylinder liner bore is not an easy operation and can be rather confusing, mainly as there are intermediate sizes and class sizes. We strongly recommend to have the work carried out by an engine shop which is familiar with these engines.

Cylinder liner bores are measured in both transverse and longitudinal planes and at three positions down the bore. The worst measurement must be taken when deciding the wear of an individual bore.

Measure the gasket face of the cylinder block in similar manner as shown for the cylinder head. If feeler gauge of more than 0.10 mm (0.0004 in.) can be inserted, the block is distorted. Re-machining of the gasket face is permissible, as long as the minimum height of the cylinder head is retained.
