PREVENTIVE MAINTENANCE

Important: Review the Bendix Warranty Policy before

performing any intrusive maintenance procedures. A warranty

may be voided if intrusive maintenance is performed during

the warranty period.

No two vehicles operate under identical conditions, as a

result, maintenance intervals may vary. Experience is a

valuable guide in determining the best maintenance interval

for air brake system components. At a minimum, the QR-1

valve should be inspected every 12 months or 3600 operating

hours, whichever comes first, for proper operation. Should

™

the QR-1

valve not meet the elements of the operational

tests noted in this document, further investigation and service

of the valve may be required.

OPERATING AND LEAKAGE TESTS

While holding a foot brake valve application:

1. Coat the exhaust port with a soap solution; leakage of a

1" bubble in 3 seconds is permitted.

2. Coat the body and cover with a soap solution. No leakage

is permitted between body and cover.

If the valve does not function as described, or if leakage is

excessive, it is recommended that it be replaced with a new

or remanufactured unit, or repaired with genuine Bendix parts.
