Squeaky noice with SS booms

[Cool Wash]

Hi All,

I am not sure how old my SS booms. Previous owner could not tell me. All of them working fine. However, I hear squeaking noice when customers pull them. What is best way to lubricate them. Is WD 40 a good idea here?

Thank you for your advice.

Thanks

Yes

WD-40 won't last very long. You need to grease them. Is there a grease fitting on the boom? You might have to take part of them down and grease the the shaft. If you take them down I'd add a grease fitting if there isn't one. Or you can take to oil them from the top if you can get to them.

Post pictures of the booms. Some of them you don't want to ever oil or grease. Some it won't do any good. If there's a grease fitting, it's okay to grease them. If it's your foam brush booms that are squeaking, they do that because there's not a bushing or bearing, so you might as well get used to it.

Use PB Blaster

Use PB Blaster

I would suggest a lubricant over a penetrating oil.

Hello MEP001,

i have uploaded pictures of my booms. Any insight is great appreciated.

Thank you.

Coleman booms, the high pressure ones should not be oiled or greased. Maybe you can find someone who can machine some nylon bearing inserts. I usually just replace the boom.

The wall mount booms are just going to squeak unless you re-engineer them to accept a nylon bushing.

There is a bakalite busing in the boom swivel about 1" x 5' long, can be removed and greased and reinstalled.

We have high pressure booms like yours. When the plastic bearing wore out we replaced it with a piece of gray conduit, drilled and tapped the center section of the boom, put a grease fitting in it and grease the boom about once a year. The foam brush boom we dab a little grease on the friction points a couple times a year.

FWIW ... just thinking out loud ... I wonder if there is a better block material option than just having any nylon block material machined. The following article (advert?) seems to suggest that UHMW is the best bushing material???

UHMW Bushings: The Ultimate Material for Better Bushings

Bushings are those little A-arm parts that you like to not think about, but there are big differences between the different materials they're made from. Here's why UHMW is the undisputed king of bushing materials.

Also by carefully measuring etc. maybe some specific 3D print option is gradually becoming more of an option vs machining?
