Crankshaft Thrust Wear For
1999-2000 Mazda 1.6 & 1.8L Engines
The AERA Technical Committee offers the following information regarding excessive crankshaft thrust wear on 1999-2000 1.6 & 1.8L Mazda engines. This wear is usually accompanied by a rattling noise that worsens with time.
APPLICABLE MODEL VEHICLES AFFECTED.
All 1999 Protege (1.6L) with VIN lower than JM1 BJ222* X0 140057
All 1999-2000 Miata with VIN lower than JM1 NB353* Y0 155947.
DESCRIPTION:
A rattling noise may be heard from the engine when depressing the clutch or when revving the engine in neutral. In extreme cases, customers may experience noise at all times. This noise is the result of an improperly machined number 4 main cap of the cylinder block, which may result in premature wear of the thrust bearing.
If end play is .012 (.3 mm) or more on the above engines, the blocks should be inspected for the above condition. AERA members report block salvage machining operations can be done to re-establish proper main bearing bore dimensions.

Flywheel Specifications For
Automotive Applications
The AERA Technical Committee suggest referring to the following
specification chart when resurfacing flywheels.
Specifications listed for S (Step) type flywheels refer to the height of the wear surface above the pressure plate mounting surface. Specifications for C (Cup) type flywheels refer to the height of the pressure plate mounting surface above the wear surface. F (Flat) type flywheels have the same height specification for the wear and pressure plate mounting surface.

Timing Chain Installation On
1979-85 Mazda 2.0L Engines
Correct installation of the timing chain on 1979-85 Mazda 2.0L
engines is critical to achieve the proper valve timing.
Rather than aligning the camshaft and crankshaft gears with marks
on the cylinder head or block, this engine uses marked plates on
the timing chain to set valve timing.
Start the timing process by rotating the crankshaft and camshaft
sprockets until the keyways are facing straight up (12 o'clock).
This should face the camshaft sprocket timing mark at 3 o'clock
and the crankshaft sprocket timing mark at approximately 5
o'clock looking at the front of the engine.
Locate the three marked links on the timing chain. Two links
should be positioned at the crankshaft sprocket so that the
timing mark is between the links (Figure 1). Position the chain
and camshaft sprocket so that the mark is in the middle of the
other marked link (Figure 2). There should be 20 unmarked plates
between the two positions.
Be careful, some timing chains do not use marked plates to
indicate the correct timing positions for the camshaft and
crankshaft. Use the old chain as a guide to make your own marks
on the new chain.
