Body Bolt Torque Guide

Variable reluctance pressure transducers may be disassembled and the range changed by installing a new sensing diaphragm. When changing diaphragms, the correct body bolt torque is extremely important to performance.

The sequence for torquing the body bolts is just like putting the wheel on a car. Try to apply the torque in stages. Do not torque one bolt fully while the others are still loose.

Here is a listing of the bolt part numbers and correct body bolt torque settings, by transducer model number:

Body Bolt Torque Requirements
Model Number Bolt Type Torque, In-Lb
DP15 & DP215 T27 Torx 125-130
DP22 & DP303 3/16" Hex 150-170
DP45 T15 Torx 20-25
DP103 T27 Torx 30-35
DP360 & DP363 3/16" Hex 150-170
All Bleed Screws 5/64" Hex 15-20
