mount plate and bolt the oil cooler to the plate using the
hardware identified in the photo below.
The Oil Cooler is attached with the following hardware:

pressure sender or a 1/8
NPT pipe plug in the
port in the side of the
case (F).
important: do not
overtighten the oil
pressure sender or the
pipe plug as this can
result in a cracked

When installing the optional oil pressure sender do not
use teflon paste or teflon tape on the threads as this will
inhibit the grounding of the sender; good grounding is
required for an accurate signal. You may even consider
adding a dedicated ground wire to the body of the
sender.
