Never fill reservoir through the air vent opening

Never fill reservoir through the air vent opening

RE: Never fill reservoir through the air vent opening

What air vent?

You need to annotate that diagram as it looks like a closed chamber to me.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

RE: Never fill reservoir through the air vent opening

Do you have a problem with following manufacturer's warnings and directions? Bad idea! What vent? Any vent.

Oil coating the vent pipe, or remaining in the vent may combine with dirt and microbes, turn to sludge and/or simply dry, blocking and sealing in any vapors from escaping.

RE: Never fill reservoir through the air vent opening

Using this oiler, you have no visual indication of the oil level in the housing. If you fill the housing from the vent, you may overfill it and not know. Simply remove the oil bulb and watch the oil level in the cup while filling and you avoid this problem. It is a good idea to fill the housing through the oiler cup just to verify it is piped correctly and there is no blockage in the line between the oiler and the housing.

You cannot fill the glass oil bulb (reservoir) by adding oil through the housing vent. Oil can't push up into the bulb unless it is turned over. Maybe that is what the note means.

RE: Never fill reservoir through the air vent opening

That too. There is no guarantee that oil will fill the reservoir, as no vapor can be forced out through the vent while it is being filled.

RE: Never fill reservoir through the air vent opening

It is also possible they are referring to the equalization tubing on the pressure equalized, non-vented design. That is usually very small tubing (0.25 inch). If you added oil through that tubing, it could form a liquid trap that would prevent the oiler from properly equalizing the pressure in the oiler to the pressure in the housing. Why would anyone try to add oil through 1/4 inch tubing?

Johnny Pellin

RE: Never fill reservoir through the air vent opening

The original question answers that question. Why would anyone try filling through any kind of vent? If they're thinking about that, any olho will do.

RE: Never fill reservoir through the air vent opening

Firsiy fill the reservoir and then fill oil bulb column
