NOTE

If big end parent bore diameter is maintained

within specifications, proper bearing dimension

is automatically achieved. However, it must be

ensured by physically checking the bearing size.

15 Measure pretension of bearing with a feeler gauge

after loosening cap bolt, opposite to bearing shell

lug. Fig. 19.

16 Remove connecting rod bearing caps.

NOTE :

Connecting rod bearing shells, no matter of which

repair stage, are precision finished and must on

no account be bored or scraped.

INSTALLATION OF PISTONS AND CONNECTING

RODS

1 Clean piston, connecting rod, piston rings and

bearing shells.

2 Warm up piston in hot oil at 70 deg C to 80 deg C.

3 Insert connecting rod in piston such that face of

connecting rod on which an arrow mark is

stamped will come on same side of arrow on

piston.

4 Insert piston pin quickly. Fit circlips using suitable pliers.

5 Assemble piston rings using piston ring expander

from top of the piston starting from 3rd groove.

Fig. 20. Ensure that ‘TOP’ mark on 2nd ring faces

piston crown.

6 Assemble bearing shells in connecting rods/caps

making sure that locating lugs of the shells are

properly seated.

In case old bearings are being reused, install marked

shells in their respective connecting rods/Caps.

7 Oil piston, bearing bores and cylinder bores.

8 Turn crankshaft and bring the crank pin onto which

connecting rod is to be assembled to top most

position.

9 Insert connecting rod with piston into cylinder

bore with arrow on piston crown pointing towards

front (forward driving direction) and arrow on

connecting rod would point towards oil cooler.
