(6) Camshaft lobe lift

Specified camshaft lobe lift (6)

Exhaust lobe ................ 7.707 mm (0.3034 inch)

Inlet lobe ...................... 7.970 mm (0.3138 inch)

(1) The 9L-9188 Spring is located in the filter

To find the lobe lift, use the procedure that follows:

bypass valve:

1. Measure the camshaft lobe height (7).

Outside diameter ............... 11.2 mm (0.44 inch)

Free length ........................ 57.9 mm (2.28 inch)

2. Measure the base circle (8).

Assembled length ............. 43.2 mm (1.70 inch)

Load at assembled length ............. 15.6 1.3 N

3. Subtract the base circle that is found in Step 2

(3.50 0.30 lb)

from the lobe height that is found in Step 1. The

difference is the actual camshaft lobe lift (6).

(2) The oil filter bypass valve must open at the

following pressure. ....................... 125 30 kPa

Maximum permissible difference between actual

(18 4.5 psi)

lobe lift and the specified lobe lift of a new

camshaft ............................. 0.10 mm (0.004 inch)

(3) Put 9S-3263 Thread Lock Compound on the

last 7.5 1.5 mm (0.30 0.06 inch) of the

threads at the base end of the stud.

Tighten the stud to the following torque. .. 68 7 Nm

(50 5 lb ft)

(4) Put clean engine oil on the filter seal. Tighten

the filter until the seal contacts the base. After

the seal contacts the base, rotate the filter by

270 degrees.
