Test data Ex:

0000001801 CONTROL LEVER ANGLE

Control lever angle measurement 1. Measure dimension Ya. 2. Measure the lever angle using the R (plate) pin hole. A = lever angle measuring hole B = pump flange face
----------
Ya=14.1~19.4mm R=61mm
----------
Ya=14.1~19.4mm R=61.0mm

0000001901 W-CSD ADJUSTMENT

Adjustment of the W-CSD 1. Setting the intermediate lever position (Refer to Fig. 1(O), 2(P).) (1)Insert a block gauge L1 between the idling set screw (H) and the control lever (G). (2)Insert a shim of thickness L2 mm between the intermediate lever (D) and the intermediate lever bracket (E). Ensure the screw (F) contacts the control lever (G), then fix the nut. 2. Adjustment of the W-CSD lever (Refer to Fig. 1(O), 2(P).) (1)Insert a block gauge L3 determined from the graph (L-t) in figure 3 (Q) between the idling set screw (H) and the control lever (G). (2)Adjust screw B until the W-CSD lever C's roller contacts the intermediate lever D. Then, fix using locknut A. Note: The temperature of the wax at adjustment must not exceed a.

Information:

Start By:a. remove cylinder headb. remove oil panc. remove oil pumpd. remove cooling tubes 1. Check the connecting rods and caps for their identification and location.2. Remove rod cap nuts (1) and cap (2) from connecting rod (3). Remove the lower half of bearing (4) from cap (2).
To protect the crankshaft from the threaded portion of connecting rod bolts (5), cut a short piece of rubber hose and install it over both rod bolts (5).
3. Remove the piston and connecting rod, then remove the upper half of rod bearing (4). The following steps are for the installation of the pistons and connecting rod assemblies.4. Put clean oil on piston rings, connecting rod bearings and cylinder bore.5. Position the piston ring end gaps 120° apart and install tooling (A).6. Put the short pieces of hose over the threaded portion of rod bolts (5), to protect crankshaft.7. With number one crankshaft throw at bottom center, install the piston and connecting rod. Engines which use one piece pistons have the word "FRONT" stamped on the crown of the piston. Make sure the word "FRONT" is toward the front of the engine when the piston is installed.8. Taking care to line up connecting rod and crankshaft, carefully tap piston into cylinder bore until tooling (A) comes off the piston. 9. Before connecting rod (3) comes in contact with the crankshaft, install upper half of rod bearing (4). Be sure the bearing tab engages the groove in the connecting rod.10. Put engine oil on upper rod bearing surface, then tap piston down, guiding connecting rod onto crankshaft.11. Position lower half of rod bearing (4) in corresponding numbered rod cap (2). Be sure the bearing tab engages the grove in the rod caps.12. Put engine oil on the lower rod bearing surface, then install the rod cap. Install the bearing cap on the connecting rod with the number on the bearing (rod) cap on the same side and same number as on the connecting rod.13. Put engine oil on the threads of bolts (5). Install rod cap nuts (1) and tighten them to a torque of 54 7 N m (40 5 lb.ft.).14. Put an alignment mark on cap and nut. Then, tighten each nut an additional 60° 5° (1/6 turn).15. Repeat the steps for the remainder of the pistons and connecting rods.End By:a. install cooling tubesb. install oil pumpc. install oil pand. install cylinder headDisassemble And Assemble Pistons And Connecting Rods
Start By:a. remove pistons and connecting rods 1. Remove snap ring (1) remove piston pin (2). Separate piston (3) and connecting rod (4).
One Piece Piston
Two Piece Piston2. Use tooling (A) and remove piston rings (5). The following steps are for the assembly of the pistons and connecting rods.3. Check the clearance between the ends of the piston rings (5). See the topic, Pistons And Rings in the Specifications section of the service manual. The oil ring is to be installed over the spring with the end gap 180° from the
