SPECIFICATIONS FOR 294-3592 Camshaft , 294-3593 Camshaft    
Callout     Part Number     Part Name     Specification Description    
4     107-7694     Thrust Plate     Thickness.........................
4.70 0.03 mm (0.185 0.001 inch)    
5     255-8664     Camshaft     End play.........................
0.13 0.08 mm (0.005 0.003 inch)
Maxium end play if worn.........................
0.46 mm (0.018 inch)
Diameter of journals.........................
65.126 0.013 mm (2.5640 0.0005 inch)    
6     -     Inlet Lobe     Exhaust Lobe.........................
7.35 mm (0.289 inch)
Inlet Lobe...............................
9.36 mm (0.369 inch)
To find the lobe lift:
Measure the camshaft lobe height (C).
Measure the base circle (D).
Subtract the base circle (D) from the lobe height (C). The difference is the actual camshaft lobe lift (B).
Maximum permissible difference between actual lobe lift and the specified lobe lift of a new camshaft is
0.10 mm (0.004 inch).

Required Tools    
Tool     Part Number     Part Description     Qty    
A     FT-2730     Hook     12    
B     8T-2998     Lubricant     -    Start By:
Remove the radiator guard.
Remove the rocker arm and the shaft.
Keep all parts clean from contaminants.Contamination of the hydraulic system with foreign material will reduce the service life of the hydraulic system components.To prevent contaminants from entering the hydraulic system, always plug or cap the lines, fittings, or hoses as they are disconnected. Cover any disassembled components and clean them properly before assembly.Clean the hydraulic system properly after any major component exchange or especially after a component failure, to remove any contamination.
Remove the oil filler tube and remove the camshaft cover from the front housing.
Use Tooling (A) to reposition the valve lifters out of the way of the camshaft.
Set the No. 1 piston to top center on the compression stroke. Refer to Testing and Adjusting, "Finding Top Center Position for No. 1 Piston".

Ensure that the timing marks on camshaft gear (1) and idler gear (2) are aligned.
Remove bolts (3) and thrust plate (4) from the cylinder block.
Illustration 4 g01032349
Do not damage the lobes or the bearings when the camshaft is removed or installed.
Remove camshaft (5) from the cylinder block.Installation Procedure
Install camshaft (5) in the reverse order of the removal procedure.
Keep all parts clean from contaminants.Contamination of the hydraulic system with foreign material will reduce the service life of the hydraulic system components.To prevent contaminants from entering the hydraulic system, always plug or cap the lines, fittings, or hoses as they are disconnected. Cover any disassembled components and clean them properly before assembly.Clean the hydraulic system properly after any major component exchange or especially after a component failure, to remove any contamination.
Note: During the installation of the camshaft, rotate the camshaft in both directions in order to prevent binding in the camshaft bearing bores.
Lubricate the camshaft lobes and the valve lifter bore with a 50/50 mixture of Tooling (B). Apply clean engine oil on the camshaft bearing journals. Carefully install camshaft (5) in the cylinder block.
When installing the camshaft, make sure the number one cylinder is at top center of the compression stroke with the timing bolt installed in the flywheel. The camshaft timing is very important. The timing mark on the camshaft drive gear must line up with the timing mark on the idler gear. Refer to the Specifications Manual for
