Hinomoto C142 and C144 valve clearance adjustment
Adjust the valve clearance on a cold engine. The crankshaft rotates 240 degrees between cylinders, the firing order is 1-3-2.
- Remove the valve cover.
- Measure with the valve closed: intake 0.30 mm, exhaust 0.35 mm.
- Adjust the adjuster, tighten the locknut to 44 Nm, and measure again.
- Reinstall the cover and tighten the valve cover nuts to 2 to 3 Nm.
Why measure cold? 0.30 and 0.35 mm are the values provided by the manual for a cold engine. A value for a warm engine is not listed.
Hinomoto C142 and C144 V-belt and clutch adjustment
Press the V-belt midway between the alternator pulley and the crankshaft pulley. The deflection should be 8 to 10 mm. A loose V-belt is a common cause of overheating, and head gasket damage in this engine usually occurs after overheating.
Adjust the free play of the clutch pedal using the adjustment rod to 15 to 20 mm.
Hinomoto C142 and C144 brakes and toe-in adjustment
Adjust the brake pedals using the turnbuckle in the middle of each rod until the travel is 20 to 30 mm and equal on the left and right. Measure the brake shoes: below 2.0 mm they are worn out. The brake drum may be a maximum of 122 mm.
Measure the toe-in between the rim edges at axle height. For 2WD this is 3 to 10 mm, for 4WD a maximum of 5 mm toe-in or 5 mm toe-out.
Tip: for the 200-hour service, order the Filterset C142-C174 (SKU-10035) and 2 bottles of Transmissieolie GL-4 10 L (SKU-15W402).
