Note: This method is very precise and effective in tightening fasteners but must be used with great care and accuracy if the nuts are to be correctly tightened; the pressures involved are quite high and the permissible tolerances minimal.
Next Section: Reassembling 31: refitting the cylinder
30.1 Compression ring top surfaces can be identified by markings and cross-sections, see text
30.2a Ensure correct piston is refitted to each connecting rod - piston may require heating to permit refitting
30.2b Ensure retaining circlips are correctly positioned, as shown
30.3 Bearing shell locating tangs must engage with cap or rod grooves - oil liberally
30.4a Arrow stamped in piston crown points to front (cam chain) end of engine - note larger (intake) valve cutaway upperrmost
30.4b Marks on connecting rod and cap should ensure correct refitting of all components
30.5 Use car-type ring compressor when refitting piston/rod assemblies
30.6 Oil liberally bearing surfaces before refitting bearing caps
30.7a Tightening big-end bearing cap retaining nuts - first stage is by torque wrench ...
30.7b ... second stage is by degrees of rotation - see text
