Put the gas/liquid separator on a chassis and connect the inlet pipe of the gas separator with the
outlet pipe. Then, connect the pipe to a nitrogen source. The nitrogen source can be connected based
on actual situation, for example, you can add a bypass interface or directly connect the nitrogen source
to the inlet/outlet pipe. If the pipe is big, cover it with tape as well. Make sure nitrogen can smoothly flow
through the gas separator.
Step 9: Install a new oil balancer.
The original oil balancer, if is found to have no impurities or other objects, can be used further more.
This part serves as a container and it does not have complex structure. However, if it contains impurities
or other objects, replace it. This is because a dirty oil balancer cannot be thoroughly cleaned.
