Component or Assembly (Procedure)
Interconnection of pits is not allowable and is treated as one pit.
The total pits, when added together, should not exceed a circle of 6 mm [0.236 in].
Only one pit is allowed within + or - 20 degrees of the nose of the camshaft lobe.
Edge Deterioration (Breakdown):
The area of edge deterioration should not be greater than the equivalent area of a 2 mm [0.079 in]
circle within + or - 20 degrees of the nose of the camshaft lobe.
Outside of the + or - 20 degrees of the nose of the camshaft lobe, the areas of edge deterioration
should not be greater than the quivalent area of a 6 mm [0.236 in] circle.
Caution: The camshaft gear will be permanently distorted if overheated. The oven tempera-
ture should never exceed 177C [350F].
Heat the camshaft gear for non-bolted 1991 and non-automotive 1994 camshafts in an oven at
149C [300F] for 45 minutes.
Heat the camshaft gear for bolted 1991 camshafts (steel gear) and all 1994 automotive to 177C
