Honda Acty — Timing & Drive Belts

Timing belt, alternator belt, and AC compressor belt — intervals, part numbers, and replacement procedure.

Danger:The E07Z is an interference engine. If the timing belt breaks while the engine is running, the pistons will collide with the open valves and the engine will be destroyed. Do not exceed the replacement interval. If the belt age or mileage is unknown, replace it immediately.

Replacement Intervals

Timing Belt Interval
100,000 km (62,000 mi) or 7 years — whichever comes first
Alternator Belt Interval
68,000 km (42,000 mi)
Water Pump
Replace with timing belt — same access
Tensioner Pulley
Replace with timing belt
Warning:Many imported Actys have unknown service histories. The 7-year rule applies regardless of mileage — a truck with 10,000 km on a 15-year-old belt is overdue. Age degrades the belt's rubber even without use.

Replacement Overview

The timing belt is accessed from the right (passenger) side of the engine, through the bed access panel. The procedure involves removing the alternator belt, valve cover, crankshaft pulley bolt, and the timing belt covers before the belt itself is accessible.

Setting TDC (Top Dead Centre)

Before removing the old belt, rotate the engine to TDC on the compression stroke for cylinder 1. On the E07Z:

  • The crankshaft timing mark (a notch on the crankshaft pulley) should align with the 0° mark on the lower timing cover.
  • The camshaft sprocket timing mark should align with the mark on the upper timing cover or valve cover mating surface.
  • Confirm cylinder 1 is on compression stroke (not exhaust stroke at TDC) by verifying both valves on cylinder 1 are fully closed.

Installation

  1. With the engine at TDC, install the new belt starting at the crankshaft sprocket, then around the water pump, tensioner pulley, and finally the camshaft sprocket.
  2. Verify all timing marks are still aligned after fitting the belt.
  3. Release or adjust the tensioner to apply correct belt tension per the factory spec.
  4. Rotate the engine two full revolutions by hand and recheck all timing marks.
  5. Reinstall timing covers, crankshaft pulley, and valve cover.
  6. Install and tension the alternator belt before starting.
  7. Start the engine and verify normal operation. Check for coolant leaks if the water pump was replaced.
Tip:Use a paint marker or chalk to mark the timing marks on all sprockets before disassembly. Photographs from multiple angles before removing anything are invaluable.

Alternator Belt

Belt Specification
10 mm wide × 675 mm outside circumference

Belt Tension

The alternator belt should deflect approximately 8–12 mm when pressed firmly at the midpoint of the longest free span. Loosen the alternator pivot bolt and adjustment bolt, reposition the alternator to achieve correct tension, then retighten. Recheck tension after running the engine briefly — new belts typically seat and lose a small amount of tension on first use.

AC Compressor Belt

Actys equipped with air conditioning have a separate belt driving the AC compressor. This belt runs from the crankshaft pulley to the compressor. Inspect it at every oil change for cracking, glazing, or fraying. Replace on the same schedule as the alternator belt. The compressor can be disengaged by switching the AC off at the dash if the belt needs replacement before a full service.
