FAQs

Below is a list of frequently asked questions regarding mast maintenance.

Why is proper lubrication important for masts?

One of the main reasons for mast failure is improper lubrication. Oil is essential for the seals and all moving components, much like in a vehicle. In winter, using thin oil is crucial as it can reach the very top sections of the mast.

What type of oil is recommended for masts?

Texaco Brand Aircraft Oil 5606-HO5: Product Code TX 1554-4, which has been used for over a decade with excellent results in prolonging mast life. It is readily available at most oil stores.

Will-Burt Oil: Highly recommended for optimal performance.

What is the recommended flow rate for Hilo Masts?

The Hilo Mast operates best when the flow rate is doubled and closely monitored. Ignoring this can cause a seal to pop off, resulting in downtime.

How can I prevent my mast from freezing in winter?

Add a mix of plumbing antifreeze and oil (70% oil and 30% antifreeze) before winter hits. This prevents freeze-ups. If necessary, the ratio can be adjusted to 60% oil and 40% antifreeze, though some lubricators may not work efficiently at this ratio.

What safety checks should I perform for older masts?

For masts older than five years, inspect the very top where the pin passes through and ensure the pin passes through a collar-type shell. If the pin only goes through the mast body, it should be replaced for safety.

Failing to address this can lead to accidents, such as the Nycoil getting caught and pulling the top load, potentially causing damage or injury.

What modifications help prevent water from gathering in Hilo Mast seals?

We recommend drilling holes closer to the seals, reducing water buildup. In some sections, water gathers up to 3 inches from the weeping holes. This modification has greatly benefited Hilo Mast customers.
