How to Install the Timing Belt in a 1989 Mazda Pickup Model 2200

The Mazda B Series is a line of pickup trucks that Mazda Motor Corporation has manufactured since 1961. The number in the model name indicates the displacement of the engine, so the B2200 has a 2.2-liter engine. This engine has a single overhead camshaft, and uses a timing belt to coordinate the opening and closing of the cylinder valves. The replacement of the timing belt in a 1989 Mazda B2200 is part of its routine maintenance schedule.

Instructions

1

Remove the cable from the negative battery terminal with a socket wrench, and detach the accessory drive belts. Disconnect the covers for the timing belt.

2

Turn the crankshaft clockwise to align the A mark on the camshaft pulley with the timing mark on the camshaft housing. Disconnect the mounting bolts for the crankshaft pulley with a socket wrench, and remove the pulley from the crankshaft.

3

Detach the spring for the timing belt tensioner with a pair of brake pliers. Disconnect the mounting bolt from the timing belt tensioner with a socket wrench and remove the tensioner. Disconnect the timing belt from its pulleys.

4

Place a T-wrench onto one of the housing bolts for the camshaft pulley. Place another T-wrench on the mounting bolt for the pulley and disconnect the mounting bolt. Remove the camshaft pulley from the camshaft.

5

Install the new timing belt and align the timing marks on the camshaft pulley if necessary. Ensure that the timing belt engages the teeth on the sprockets of the camshaft, crankshaft and belt tensioner.

6

Install the mounting bolt for the belt tensioner and tighten it by hand. Install the tensioner spring, and loosen the lock bolt for the belt tensioner with a socket wrench.

7

Turn the crankshaft clockwise by two turns and align the timing marks. Tighten the locking bolt on the timing belt to between 28 and 38 ft. lbs. with a torque wrench. Turn the timing belt tensioner to adjust the tension on the timing belt. The timing belt should deflect by about 12mm when you apply a force of 22 lbs. to the longest span of the timing belt.

8

Replace the covers for the timing belt with a socket wrench, and attach the accessory drive belts. Connect the cable to the negative battery terminal.
