3408C ENGINE FOR CATERPILLAR BUILT MACHINES Caterpillar


Camshaft

Usage:

(1) Camshaft gear.

(2) Interference fit between the gear and camshaft ... 0.058 to 0.138 mm (.0023 to .0054 in)

(3) Diameter of the surfaces (journals) for the camshaft bearings (new) ... 69.850 ± 0.013 mm (2.7500 ± .0005 in)

Bore in front and rear bearings for the camshaft (new) ... 69.972 ± .058 mm (2.7548 ± .0023 in)

Bore in three inner bearings for the camshaft (new) ... 69.972 ± 0.058 mm (2.7548 ± .0023 in)

(4) Thickness of thrust plate (new) ... 4.65 ± 0.03 mm (.183 ± .001 in)

Endplay of the camshaft ... 0.10 to 0.25 mm (.004 to .010 in)

(5) Height of camshaft lobes.

To find lobe height, use the following procedure:

A. Measure camshaft lobe height (5).

B. Measure base circle (7).

C. Subtract base circle (Step B) from lobe height (Step A). The difference is actual lobe lift.

D. Specified camshaft lobe lift (6) is:

a. Exhaust lobe ... 8.783 mm (.3458 in)
b. Intake lobe ... 8.100 min (.3189 in)

Maximum permissible difference between actual lobe lift (Step C) and specified lobe lift (Step D) is 0.13 mm (.005 in)

Projection of dowel at tapered end of camshaft ... 8.76 ± 0.25 mm (.345 ± .010 in)
