Can you over oil a valve?

    Just putting together an Information Sheet on instrument care and maintenance and have come across the following comment

    "There is no negative effect from over oiling the valve! You can't use too much -- don't be stingy! (Take care where the excess oil goes -- don't get it on your clothes, carpeting, or furniture.) "

    can over oiling cause problems?

    Other than the excess 'gunge' that usualy forms at the bottom of the valve from using valve oil I doubt it very much?.

    Yes... you can easily over oil a valve... An if you play too fast it will burst into flames.... :)

    There are some grey areas as to how much oil you should put on your valves.

    Some instruments require very little oiling and run better nearly dry where others need constant oiling and you never seem to be able to put enough on before it needs oiling again.

    I think the best advice you can give is:-

    When oiling the valves:-

    1 remove any moisture from the valve with a soft cloth
    2 apply a little oil and re-insert the valve checking that the up and down motion is free and slick
    3 repeat step 2 until the above mottion is reached
    4 check each tim you take the instrument out of the case and follow steps 2 & 3 accordingly

    Only my opinion but it works for me

    Any excess oil will simply drip out of the hole on the bottom of the valve and ruin your clothes ...

    Oiling a dirty valve can often lead to excessive build-up of grunge in the valve, which often makes it worse. A clean valve is a happy valve ;)

    GingerMaestro's technique seems like the best way to go to me. Make sure that any cloth you use does not give off any lint, because a valve covered in lint does not work well. It's also sometimes a good idea to wipe down the inside of the valve casing (remove the valve, remove the bottom cap, put a bit of oil around the top of the casing and then use your soft cloth to spread it over the inside of the casing).

    I would be interested to know how much slide oil is too much when it is applied to the Conductors baton during the break in a gig, while the conductor is at the BBQ waiting for his third steak baguette? especially when the conductor has a habit of putting the stick in his mouth while sorting out his scores?

    A Bass trombonist I know has a couple of supplimentary questions regarding this fascinating topic, firstly what is the best way to clean slide oil off your band uniform after the condutor has smeared the back of your jacket with the stuff, and secondly, and rather more seriously, what are the long term health effects of having a bottle of slide oil stuck up your.............(rest of post passed on to Sheffield police for further inquiries)

    Have to pretty much agree with first few comments - over oiling a valve simply ends up with the oil dripping out of the hold in the 'sump' of the valve, but adding more and more oil to a valve which is sticking because it is dirty won't sort the problem out & may make it worse by adding / redistributing dust & grime each time you take it out.

    A lot of people chuck gallons of oil onto their valves, but often the cause of sticking valves is somewhere else. This is in no way definitive, but try going down a checklist;

    1) Is the valve clean?
    2) Are the valve guide/slot clean?
    3) Is it lined up correctly?
    4) Does the valve 'spin' in it's casing? (The valve should turn all the way round in it's casing without catching)
    5) Are the pads clean and at the correct thickness?
    6) Is it a new Sovereign? (Don't get me started on Besson's penny pinching; stainless steel is not a bearing material, but why did they use it for valves? Because it's cheaper than Monel):mad:

    Once you have gone down the checklist, you shouldn't have a sticky valve. Be aware though, that some valve oils are not compatible with each other. For example 'Blue Juice' is great stuff, but it reacts with other valve oils, so you need to make sure that you only use one brand.

    tMPers, feel free to add to the checklist, it's just off the top of my head.

    - :-? ... I'm a little bit worried about this one as valves are sometimes hand-lapped to ensure good fit. Spinning valves could undo this work!

    Getzen use stainless steel over Monel valves and the have one of the finest reputations in valves.
    Bauerfine use stainless steel and are the best valves I have come across.
    Monette are now making their own valves (which I believe to be steel)

    Nowt wrong with steel for valves, if they are the ones using it - don't generalise because of Besson

    I've found that cleaning the bore of the valve is just as important as cleaning the valve itself. I use a plastic chopstick. wrap a lint-free cloth round it and gently push through the bore.
    As for oil, if you have enough on to cover the surface of the valve any more is waste, and it's dear stuff!
    Regualr washing the instrument out is a big help too, or you just blow more crud from the tubes on to your newly clean valves.

    I'm having a problem with mine too - especially when we've been out playing in 30+ degrees - does this kind of heat have an effect on the valves?
     
  18. matti_raz

    matti_raz Member

    Yes......
    The heat evaporates Valve Oil a lot faster meaning you need to oil them alot more than cooler times, say Winter......... When Valves can survive from November till February without oil ;) *AHEM*

    Almost certainly. The heat will cause the metal to expand - meaning the valves will grow and the bores will shrink slightly closing up the clearance. I've noticed the valves on my flug have been a little sluggish too since we've had the hot weather.

    And of course, this effect will be most noticeable if the valves and the casings are made of different materials - e.g. steel/brass/copper and monel - rather than made of the same stuff.....
