CAUTION
DAMAGE TO RESOLVER
Be sure that the sprocket or gear driving the resolver chain or timing belt is mounted so that it is
centered on the crankshaft. If the gear or sprocket is mounted off-center, the resulting loads on the
resolver shaft may cause the resolver to fail.
Failure to comply with these instructions could result in property damage.
Wintriss Controls Group stocks a spring-loaded base (part# 4194300) with a hole pattern that matches
the hole pattern on the resolver.
The resolver can turn in a clockwise or counterclockwise direction. You can change the direction of
rotation by swapping the black and yellow wires on the resolver connector (see Table 2-2, page 55).
When designing the drive for the resolver, make sure that the drive allows for adjustment of the
resolver to its zero position at top dead center. All sprockets must be keyed or pinned. The resolver
shaft has a standard key.
Design a method of driving the resolver directly from the crankshaft, using a chain or timing belt (not
a V belt) and sprockets. Use either an idler sprocket or spring-loaded resolver base to compensate for
slack or stretch.
Observe these additional precautions when designing the resolver drive:
•
Do not use a long, sloppy chain. The distance between the center of the resolver shaft and the
center of the crankshaft should be no more than 3 feet (1 m).
•
Do not use gears, right-angle joints, or shafts with universal joints because these will develop too
much backlash or too much play.
