Timing setting

(1)Pump vertical direction
(2)Key groove position at No. 1 cylinder's beginning of injection position (at BTDC: aa).
(3)Position of the key groove of the No. 1 cylinder at B.T.D.C. bb (fix the governor flyweight at this position for delivery).
(4)B.T.D.C.: aa
(5)At second timing adjustment, set the camshaft at the * position and tighten the flyweight locknut.
(6)Align the flyweight's timing gear position with the lockpin groove and then fully tighten the flyweight to the camshaft.
(7)Remove the lock pin and adjust the governor. Reinstall the lock pin to fix the flyweight for delivery.

Partsstock action only PRODUCT IMPROVEMENT PROGRAM FOR REMOVINGCERTAIN REMAN FUEL INJECTORS FROM DEALER PART STOCK
7750 PI70071
The information supplied in this serviceletter may not be valid after the termination date of this program. Donot perform the work outlined in this Service Letter after the terminationdate without first contacting your Caterpillar product analyst.TERMINATION DATE
February 29, 2004PROBLEM
Certain fuel injectors need to be removed fromdealer part stock. A number of fuel injectors were built with a Valve OpeningPressure (VOP) spacer that missed a hardening operation. This non-hardenedspacer allows premature wear, causing several operational problems whichmay include: engine misfire, low power, white smoke, and engine would notstart.ACTION REQUIRED
Only remove engine injectors within the suspectdate code range from your parts supply.
In order to perform this inspection, injectorsmust be removed from the packaging.
Repackage all injectors.
