Conditions for Oil Sampling
The oil sample must be taken with the vehicle in the “off” state and on a flat surface with the e-Axle at zero
degrees orientation. The operator must chock the wheels, apply the parking brake, and take any other steps
necessary to keep the vehicle from moving.

Extraction of Fluid Sample
To collect a sample under these conditions, a suction hose must be installed into the banjo housing to collect an
oil sample from the target location. Remove the oil fill plug from the fluid fill port. Refer to Figure 1, Item 2. Place
the oil fill plug in a clean environment, free from contamination.

The hose I.D and syringe must be debris free. Cut the hose as needed to meet desired service length. Insert the
hose and maneuver it to the target location. Refer to Figure 2. Once the desired location is achieved, assemble
the 1/4 in. oil suction hose to the 1/4 in. syringe and pull the required quantity of oil sample.

NOTE: A new suction hose and a clean syringe is the preferred method of oil sampling. If a new suction
hose is not used, an oil sample may be pulled from the e-Axle and purged, rather than collected into the
oil sample bottle.
Remove the sealed lid from the oil sample bottle and fill the bottle to the fill line with the oil sample. The oil sample
must be at least 100 ml. Install the oil sample bottle lid and secure the lid with tape. Place the oil sample bottle
into the pre-paid shipping container/bag and install the shipping label on the exterior of the container/bag.
Refill the e-Axle with the required amount of oil as needed. Install the oil fill plug. Torque to 47-57 N·m (34.6-42 lb
ft).
