BRKTBracket unit 7-7562Y3A11 Checking the power trim and tilt motor 1. Check the commutator for dirt or foreign substances. Clean with #600 grit sand- paper if necessary. 2. Check the commutator undercut for dirt or foreign substances. Clean with com- pressed air if necessary. 3. Measure the commutator diameter a . Replace if out of specification. 4. Check the armature coil for continuity. Replace if out of specifications.5. Check the circuit breaker for continuity. Replace if there is no continuity. 6. Measure the brush length. Replace if out of specification. 7. Check the base for cracks or damage. Replace if necessary.

Install the oil seal 1 and the bushing 2 into the motor base 3 as shown. 2. Attach the circuit breaker 4 onto brush 1 5 together with the brush holder 6 and connect the wire lead 7 . 3. Install the springs 8 into the motor base, then the brush holder into the motor base together with the brushes and circuit breaker. 4. Install the armature 9 , O-ring 0 , and yoke A . Installing the power trim and tilt 1. Fully tilt the outboard up, and then sup- port it with the tilt stop lever 1 . WARNING After tilting up the outboard, be sure to support it with the tilt stop lever. Otherwise, the outboard could suddenly lower if the power trim and tilt unit should lose fluid pressure.
