Usage:
(1) Thickness of washer (new) ... 8.50 ± 0.05 mm (.335 ± .002 in.)
Thickness of groove in camshaft (new) ... 8.75 ± 0.05 mm (.344 ± .002 in.)
End play for the camshafts (new) ... 0.15 to 0.35 mm (.006 to .014 in.)
(2) Diameter of the surfaces (journals) for the camshaft bearings (new) ... 85.88 ± 0.02 mm (3.381 ± .001 in.)
Bore in the bearings for the camshafts (after assembly) ... 86.00 ± 0.06 mm (3.386 ± .002 in.)
(4) 3512 and 3516 Engines:
Clean the threads of the bolts and the contact surfaces of the parts thoroughly. Put 9S3263 Thread Lock on the bolt threads and tighten to a torque of (hand tighten only) ... 55 ± 7 N·m (41 ± 5 lb.ft.)
(5) Height of camshaft lobes.
To find lobe height, use the procedure that follows:
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.
- a. Exhaust lobe ... 9.078 mm (.3574 in.)
- b. Intake lobe ... 9.314 mm (.3667 in.)
- c. Injector lobe:
Engines rated at 900 to 1300 rpm ... 13.574 mm (.5344 in.)
Engines rated at 1301 to 1800 rpm ... 13.731 mm (.5406 in.)
- b. Intake lobe ... 9.314 mm (.3667 in.)
D. Specified camshaft lobe lift (6) is:
