0000001801 STOP LEVER ADJUSTMENT

Adjustment of the stop lever 1. Confirm that the starting injection quantity is within standards at the normal position. If below the specified lower limit, move the stop lever serrations one tooth and reconfirm. 2. Pull the stop lever (A) to the fuel cut direction at the standard idling speed of N and adjust the screw (B) to the position Q. Fix nut (C) to the torque T at the position where the clearance between the stop lever and the end of the screw is L mm (the screw is returned 2 turns). The head of the screw must protrude above the face of the nut. If the head of the screw is below the face of the nut, adjust the clearance between the stop lever A and the end of the screw at Q to L mm or more. 3. If adjustment in item 2 is not possible, move the stop lever installation position 1 tooth. 4. The stop lever's operating force is max. M kg (at R = 35). The stop lever must operate smoothly.

Information:

Start By:a. remove exhaust manifoldsb. remove push rods and valve liftersc. remove water temperature regulators Put protection caps on all fuel openings. 1. Remove the bolts and valve cover base (1) from the cylinder head assembly.2. Disconnect hose (2) from the cylinder head assembly. 3. Put identification marks on wires (3), and disconnect them from the sending unit. 4. Remove six head bolts (4), and install Tooling (A). 5. Fasten a hoist to Tooling (A), and remove the remainder of the bolts that fasten the head assembly.6. Remove cylinder head assembly (5). The weight of the head assembly is 102 kg (224 lb). A new spacer plate gasket must be installed when the cylinder head is removed. See Remove & Install Spacer Plate.Install Cylinder Head Assemblies
1. Thoroughly clean the spacer plates and bottom surface of the cylinder head assemblies. Install a new head gasket and seals. Do not use any adhesives. A new spacer plate gasket must be installed when the cylinder head assembly is removed. See Remove And Install Spacer Plate. 2. Fasten Tooling (A) to the cylinder head assembly, and put cylinder head assembly (1) into position on the spacer plate. The use of guide bolts will help put the cylinder head assembly in alignment with the spacer plate.
(1) Large bolts (3/4 in). Put 6V-4876 Molycoat Paste Lubricant on the threads and between washer and underside of the cylinder head bolts. (2) Small bolts (3/8 in). See Step 3h.3. Install cylinder head bolts and washers. Tighten the bolts in the following sequence:a. Tighten bolts 1 through 10 in number sequence to 270 25 N m (200 20 lb ft)b. Tighten bolts 1 through 10 in number sequence to 470 20 N m (345 15 lb ft)c. Tighten bolts 1 through 10 in number sequence again to 470 20 N m (345 15 lb ft).d. Install the rocker arm shafts for the engine valves.e. Tighten bolts 11 through 18 in number sequence to 270 25 N m (200 20 lb ft).f. Tighten bolts 11 through 18 in number sequence to 450 20 N m (330 15 lb ft).g. Tighten bolts 11 through 18 in number sequence again to 450 20 N m (330 15 lb ft).h. Tighten the nine small bolts (2) to 45 7 N m (33 5 lb ft). 4. Connect hose (3) and the wire assembly to the cylinder head. 5. Install valve cover base (2) to the cylinder head. Tighten the bolts to a torque of 14 4 N m (10 3 lb ft) and the sequence as shown.End By:a. install water temperature regulatorsb. install push rods and valve liftersc. install exhaust manifolds
