Remove the connecting rod caps, and slip short
sections of rubber hose over the threaded ends
of the connecting rod bolts.

lnstall the ring compressor. check that the bear-
ing is securely in place, then position the piston
in the cylinder, and tap it in using the wooden

lf the crankshaft is not installed:
. Remove the rod caps and bearings, install the ring
compressor, then position the piston in the cylin-

lnstallation
Before installing the crankshaft, apply a coat of
engine oil to the main bearings and rod bearings.
Insert the bearing halves into the cylinder block and
connecting rods.
Hold the crankshaft so the rod journals for cylinders
No.2 and No. 3 are straight down.
Lower the crankshaft into the block, seating the rod
journals into connecting rods No. 2 and No. 3, and
install the rod caps and nuts finger-tight.

Botate the crankshaft clockwise, seat journals into
connecting rods No, 1 and No.4, and install the rod
caps and nuts finger-tight.
NOTE: Install caps so the bearing recess is on the
same side as the recess in the rod.
Check rod bearing clearance with plastigage (see
