TESTING AND ADJUSTING TESTING AND ADJUSTING FOR FUEL INJECTION TIMING 2. Remove bolt (3) and fix drive gear (4) to holder (5) with fixing bolt [2]. a As fixing bolt [2], use a bolt 6 mm in thread diameter and 35 mm in length. a Pass the fixing bolt through the screw hole of bolt (3) and tighten it into the screw hole of the drive gear, and the fuel injection pump is fixed in the fuel injection timing. ADJUSTING BY DELIVERY VALVE METHOD a After repairing or replacing the fuel injection pump or timing gear, adjust the injection timing according to the following procedure. ADJUSTING a Apply the delivery valve method to only adjust- ment of the injection timing. 1.
Open the engine hood and remove all cylinder head covers (1). 3. Install the fuel injection pump, holder, and drive gear together. a See DISASSEMBLY AND ASSEMBLY, Removal, installation of fuel pump assembly. a After installing the fuel injection pump tempo- rarily, check the fuel injection timing accord- ing to the above described procedure. 2. Remove the engine undercover (on the radiator side). 3. Rotate the crankshaft forward to bring the stamped "1.4TOP" line (a) of the crank pulley to pointer (2) and set the No. 1 cylinder to the com- pression top dead center. a Crank the crankshaft with the crank pulley mounting bolt. a There are 2 stamped "1.4TOP" lines on the crank pulley.
Use the one at the diagonal position of "2.3TOP". a When the No. 1 cylinder is at the compres- sion top dead center, the rocker arm of the No. 1 cylinder can be moved by the valve clearance with the hand. If the rocker arm cannot be moved, the No. 1 cylinder is not at the compression top dead center. In this case, rotate the crankshaft one more turn. 4. After finishing adjustment, remove the measur- ing tools and return the removed parts. k Be sure to remove pin [1] and fixing bolt [2]. 3 Cylinder head cover mounting bolt: 7.84 – 9.8 Nm {0.8 – 1.0 kgm} PC130-7 20-113 (1)
