The following new service information outlined in this bulletin will aid technicians in providing
easy to follow valve body reconditioning instructions and new illustrations to simplify reassembly

Inspection Procedure
1. Using the exploded views in this bulletin, inspect each bore for freedom of valve(s)
movement and evidence of debris. Pay particular attention to those valves related to the
customer’s concern.
2. Verify movement of the valves in their normal installed position. Valves may become
restricted during removal or installation. This is normal due to small tolerances between
the valves and bores.
3. If a valve is restricted and cannot be corrected by cleaning valve and bore, then replace
valve body. Describe restricted valve on repair order.
