Q: Why is checking the case drain line pressure critical before starting up a new 706-73-01181 motor?
A: High case pressure will blow out the shaft seal, leading to immediate hydraulic oil leakage into the lower gearbox.

Q: How does the bimetallic valve design protect the motor from seizing up during sub-zero winter morning startups?
A: The expansion coefficients of the paired metals allow uniform clearance changes, preventing scoring before the system reaches operating temperature.
