FAQ: Gravity Feed Oilers

What is the recommended oil viscosity range for the gravity feed oilers?

Gravity feed oilers can use oils up to 50W viscosity (SUS 2000 @ 100 F). As always, operating temperature is important to insure flow. The oil must be in a liquid form to be able to flow in the environment where the gravity feed oiler is to be located.

Are the type "KL" oilers available with metric threads instead of NPT?

No. However, there are adapters that can be used to convert it from NPT to BSPT threads. For 1/8 NPT use part number 14202R, for 1/4 NPT use part number 14208R and for 3/8 NPT use part number 14209R.

Are the type "KL" oilers likely to be affected by high frequency vibration?

Where extreme vibration exists, it is recommended to connect the lubricator to the lubrication point by means of flexible hose or tubing.

What are the outside diameters (OD) of the wicks used in the vari-feed oilers?

The outside diameters of the wicks used on the vari-feed oilers are as follows: white(very fast)- 3mm, green/white(fast)- 5mm, green(medium)- 6mm, red/white(slow)- 8mm, and red(very slow)10mm.

Is there a way to tell if a chain is receiving inadequate lubrication?

Check the chain for elongation, if chain is more than 3% longer than its normal length there is a need to evaluate the lubrication method.

What is the diameter of the stainless steel & nylon bristles on the applicators?

The nylon bristles have a diameter of 0.008", the stainless steel ones have a diameter of 0.005".

Can the valve on the remote rotary bracket/valve assembly be completely shut off?

Yes. The needle valve in this assembly will stop the flow of oil.

Can an adapter be used to mount an applicator to either a "VM" manifold or a "S" bracket at a 45 degree angle?

Yes. Use a 10648R fitting. This fitting can be mounted to either end of the adjustable applicator assembly to make the 45 degree desired angle.

Are the type "VM" & "V" manifolds expandable?

Yes. When the plug on the end of the manifold is removed, it has a 1/8 NPT thread connection. A hex nipple could be used to connect this manifold to another one. The 10971R connecter fitting on the second manifold would need to be removed.

What can you do to prevent or eliminate fogging or cloudiness of reservoirs, especially acrylic?

If oil is attacking the reservoir, use glass. If you are cleaning the reservoir, you must use a solvent that will not attack the acrylic.

Why are the needle valves in the manifold delivering an inconsistent drip rate?

Needle valves may be clogged. Clean out plugs are located at each end of the manifold should internal cleaning be necessary. The manifold can be flushed or blown out by removing these end plugs.

What is the recommended oil viscosity range for the chain oilers?

Chain oilers can use oils up to 50W viscosity (SSU 2000 @ 100 degrees Farenheit). As always, operating temperature is important to insure flow. The oil must be in a liquid form and be able to flow in the environment where the gravity feed oiler is to be located.

On the initial installation of a gravity feed oiler, why is there no oil dripping into sight area?

Since the unit has not been used previously, air bubbles may get trapped in the line(s). Open all neelde valves slightly to permit system to fill and trapped air to escape from the lines and manifolds. Air bubbles may appear in drip sights, but will disappear as soon as all air has escaped.

What is the advantage of using the glass versus the acrylic with the gravity feed oilers?

For applications where the temperature exceeds 160 degrees Farenheit, glass reservoirs are recommended. If temperature is not an issue, the acrylic reservoir provides a less expensive, durable substitute.

Are the solenoids on the gravity feed oilers normally open or closed?

All solenoids on these oilers are normally closed (NC).

What are the maximum operating temperatures of the applicators for the chain oilers?

Even-Flo Applicators – nylon and stainless steel operate at the same temperature of 160 degrees Farenheit. Ever-Last Applicators – operate at a temperature of 200 degrees Farenheit. Round Brush Applicators – nylon and stainless steel operate at the same temperature 160 degrees Farenheit. Rotary Applicators – nylon operate at 250 degrees Farenheit, stainless steel at 400 degrees Farenheit.
