Note: Plastic gauge may not be necessary when the
engine is in
the chassis.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Note: Caterpillar does not recommend the checking
of the actual bearing clearances particularly on
small engines. This is because of the possibility of
obtaining inaccurate results and the possibility of
damaging the bearing or the journal surfaces. Each
Caterpillar engine bearing is quality checked for
specific wall thickness.
Note: The measurements should be within
specifications and the correct bearings should
be used. If the crankshaft journals and the bores
for the block and the rods were measured during
disassembly, n o further checks are necessary.
However, if the technician still wants to measure the
bearing clearances, Tooling (A) is an acceptable
method. Tooling (A) is less accurate on journals with
small diameters if clearances are less than 0.10 mm
(0.004 inch).
NOTICE
Lead wire, shim stock or a dial bore gauge can dam-
age the bearing surfaces.
The technician must be very careful to use Tooling (A)
correctly. The
following points must be remembered:
•
Ensure that the backs of the bearings and the
bores are clea
n and dry.
•
Ensure that the bearing locking tabs are properly
seated in the t
ab grooves.
•
The crankshaft must be free of oil at the contact
points of Tool
ing (A).
1. Put a piece of Tooling (A) on the crown of the
bearing that
is in the cap.
Note: Do not allow Tooling (A) to extend over the
edge of the be
aring.
2. Use the correct torque-turn specifications in order
to install th
e bearing cap. Do not use an impact
wrench. Be careful not to dislodge the bearing
when the cap is installed.
Note: Do not turn the crankshaft when Tooling (A)
is installed.
3. Carefully remove the cap, but do not remove
Tooling (A). Measure the width of Tooling (A)
while Tooli
ng (A) is in the bearing cap or on the
crankshaft journal. Refer to Illustration 263.

Typical Example
4. Remove all of Tooling (A) before you install the
bearing cap.
