How to repair a loud Trombone rotary valve 

it’s people like you who save lives

Worked like a charm! Thanks for the tip. I also just found that my 42BO (going on 20 yrs old) was clicking when it returned to the bumper. The rubber had been smashed down from all the use, and had become hard. The top bumper was a lot fresher, so I just switched them and am now hearing less bumping. Will probably replace them with fresh rubber sometime soon, but it was another good quick fix.

Nice tip! I'm fortunate to have the nylon ball and socket linkage on my 90's model Bach 42 with the Thayer valve, but I'm frequently annoyed by other players with noisy linkages.

Hey, I like your fix, but just a quick FYI....hetman and other brands of instrument lubricants often offer a specific type of oil called "ball joint" or "linkage" oil made for this job. This grease is a little less thick than tuning slide grease, allowing for faster action and often comes with a special applicator tip to get lube the tight spots on the linkage without unscrewing any part of the linkage.

Bach trombones are known for their noisy rotary valves.

Thanks! great vid! It's kinda ironic to use piano jazz in the background for a trombone tutorial. :)

Also replace the rubber stop pads every few years. They can get loud too.

Thank you for the vid btw

Pretty good video since I have a 42bo also

Hello my friend, that you are using the rotor screws, is a special paste or some kind of fat?, Explain please ...... sorry I speak Spanish and translated into English ..... thanks

Mine literally sounds like a car crashing through a garage door

I also have a back 42bo and the rotar linkage is quite noisy

You forgot to mention dried out bumpers.

Looking for the linkage rod if anyone knows where i can buy one but not pay $130.00 for the entire kit

What model is this trombone?

Charlie browns friend!
