Inspection
See Figures 7-49 through 7-52.
IMPORTANT
Tappets and shims must be removed before
measuring camshaft bearing clearance.
Be sure to note location and shim thickness of each
tappet.
Figure 7-49
1. Remove twelve tappets with shims. Be sure to note
location and shim thickness of each tappet.
2. Clean the camshaft journals and housings free of all
oil.
3. Tear off a piece of Plastigage as long as the full
bearing width. (Tear through both the envelope and
plastic thread at the same time.) Lay the piece of
Plastigage across the full width of the lower bearing
shell about 1/4 in. (6.3 mm) off center.
Figure 7-50
IMPORTANT
Do not turn camshaft during oil clearance
measurement process.
Be sure dowel pins are properly aligned before
installing camshaft housings.
4. Install the camshaft housings. Apply engine oil to cap
screws and tighten using sequence (1 through 11) at
increments of 32 lb-in. (3.6 N•m) until specification is
reached. Do not turn camshaft during measurement
process.
Cam Housing Cap Screw Torque: 97 lb-in. (11 N•m)
Figure 7-51
5. Remove cap screws and camshaft housings in
opposite sequence of installation. The flattened
Plastigage (12) will adhere to either the bearing shell
or the camshaft.
6. Using the supplied scale (13), take the measurement
at the widest point of gauging plastic.
Camshaft Oil Clearance Standard: 0.002—0.003 in.
(0.045—0.087 mm)
