T60 REGULATOR
This PPI covers the repair of Series I and II T60 regulators using either a minor or major repair kit.
Important: Any maintenance, service or repair
should be performed by trained and experienced
service technicians. Proper tools and equipment
should be used to prevent injury to the servicing
technician, property or system components. Service
repairs should always be performed in a safe
environment and the technician should always wear
protective clothing and eyewear to prevent injury.
The IMPCO PPI-68 repair kit instructions will provide
the technician information to successfully repair
Model T60 regulators. Always inspect the major
casting pieces for damage, corrosion or cracks
before attempting a service repair. Refer to the
illustrations at right to properly identify the T60 as a
Series I or II.
NOTE: The T60 Series I uses imperial screws and
the Series II uses metric. Extra imperial and metric
screws are included in the repair kits—be sure to use
the correct screws when reassembling the regulator.
NOTE: Although identical in dimensions and
appearance, the primary and secondary seats are
made of different material. To differentiate the two
seats, the secondary seat is red in color, or black but
marked by a small white dot.
Do not use Teflon tape to seal any fuel
fittings. Fragments of the tape may enter
into the fuel system, causing damage or
malfunction of critical fuel system
components that may result in serious
injury and/or property damage.
