Gentleman,
I got back two additional reply's from the Parker / Baldwin staff about the tiny hole in the filter.
I wrote to Randy again for clarification as to what he previously told me about the hole in the filter. I stated:
Just to clarify. The small hole in the cap is there to allow oil to flow freely through the filter (without being filtered) until the oil warms up enough (gets thinner) to be able to go through the actual pleated filter material? Am I understanding you correctly? Thanks for taking time out to help me with this.
Randy wrote back and said:
That is correct. By-pass filters will filter the oil over time so eventually the contaminants will be filtered out even with the warm up orifice.
Travis R. Winberg / Manager - Service Engineering /Parker Hannifin Corporation / Filtration Group also replied and said:
The small hole in the center of the B164 is a metering orifice to restrict flow through this filter so that the majority of the oil coming from the pump flows through the full-slow circuit. Only about 10% of the oil coming from the pump should flow through the by-pass flow circuit.
So there you go. That's the info they gave me on the hole in the dome end cup on the B164 Filter.
