10 Stagger piston ring gaps such that they are 180

deg apart. Clamp piston ring compressor over

piston rings upto out side diameter of piston so

that it can slide over it with little force. Fig. 21.

Push piston assembly in cylinder bore gradually

by using mallet handle till connecting rod locates

on crankpin. Fig. 22. Now rotate crankshaft slowly

and simultaneously pushing piston assembly till

the crankpin reaches bottom most position.

11 Install connecting rod cap with bearing, on

connecting rod ensuring that identification

number of connecting rod as well as on cap are

matched and bearing shell lugs are on same side.

Hand tighten connecting rod cap fasteners.

12 Assemble remaining piston - connecting rod

assemblies in same manner.

13 Turn crankshaft and bring any one pair of pistons

to BDC. Tighten fastening bolts of this pair with

torque wrench to specified torque. Fig. 23.

14 Similarly tighten remaining connecting rod bolts.

15 Check connecting rod axial play or side clearance

and distance between piston crown (at TDC) and

cylinder block top surface. These should be within

specified limits.

16 Check free running of connecting rod bearing.

When crankpin and connecting rod bearing

dimensions are maintained within specified

values, running clearance between crankpin and

bearing is automatically ensured.
