9. Remove the three (3) high-power feedthroughs using a 36mm wrench.
10. Remove the three (3) high-power feedthrough O-rings from the Main housing if they did not come out
with the old feedthroughs.
11. Inspect the sealing area for any residue or debris and clean the threads with a lint-free cloth if needed.
4.23.5.8 High-Power Feedthrough Installation
1. Clean the feedthrough mating surfaces with a lint-free cloth. Inspect the sealing area for any damage.
2. Verify that the old high-power feedthrough O-rings have been removed.
3. Lubricate and install new O-rings onto the High-Power Feedthroughs.
• • • CAUTION • • •
Be sure to fully seat the O-ring into the grove in the feedthrough. Failure to do this can result in damage to the O-ring while tightening.
4. Finger-tighten the High-Power Feedthroughs into the Main housing and then torque to specification.
Continue to Step 5 for the PPS High-Power Feedthroughs. Continue to Step 7 for the Stainless-Steel
High-Power Feedthroughs.
5. Secure the ring terminals to the PPS High-Power Feedthroughs using the M10x16 fasteners from the
inside.
6. Once the M10x16 fasteners are finger tight, torque them to 14 Nm (10 ft.lb). Continue to Step 9.
• • • CAUTION • • •
Hold the high-power feedthrough using a 36mm wrench while applying torque to the M10 fasteners to prevent loosening or over
torqueing the feedthrough assembly.
7. Secure the ring terminals to the Stainless-Steel High-Power Feedthroughs using the M10 nuts and
washers from the inside.
8. Once the nuts are finger tight, torque them to 15.5 Nm (11.5 ft.lb). Continue to Step 9.
• • • CAUTION • • •
While torqueing the High-Power Feedthrough Nuts, it is important to hold the inner nut with a wrench. Failure to do so could place an
excessive load on the feedthrough causing internal damage. Also, the feedthrough itself could move which could allow it to loosen or be
over torqued.
9. Install wires on the inner thermistor terminals and then install the Cover Plate. Refer to 4.23.5.6 Motor
Cover Plate Installation on page 199.
10. Leak test and evacuate in accordance with standard industry practices.
11. Connect the two (2) connectors to the thermistor sensor feedthrough. Refer to Figure 4-227
Connection to Stator on page 203.
