HW99 galling

Recommended Posts

It when metal rubbs on metal and wears a grouve damaging the parts .

Grease is only a temp sloution .

Silicone lube  can actually make it worse .

My lightening sufferes from it a bit on the cocking link 

Same place as the hw 99 (common issue ) 

Get some disulphide  greese on it first 

Its often enough to keep the issue at bay .but if left can get worse and greese wont help much .

Few guys over on the Airgun Forum who could sort it out for you if you dont want to tackle it yourself....Blackmax is a good place to start.

hello, sounds like it needs a service, not to difficult to do, look on u tube stripping down a HW 99 by nick stanning who is tinbum tuning kits, get a spring clamp and one of his kits or google TbT tune kits, he has people around the UK fitting them so might be someone near you, good luck

if it is the cocking lever............on some other english air rifles you have what is called "a slipper plate"...can be made out of steel or brass...........it is often the case that this piece is lost when people fiddle about with a gun.........check the drawings that you are not missing it.........

How easy is a hw99 to work on? Just that I maybe able to get a used one that I think just needs a replacement spring 

a new one for a bsa is only £4.80

Galling when two metals under load cold weld and year apart. Stainless steel threads are a nightmare so is aluminium.

Polishing the surfaces and using good lube can help short term. Brazing/tinning the surface of the moving part with brass and filing back would work.if no slipper plate can be had.

Blackmax definitely. Very good with his Weihrauchs and really thorough guy. My hw100 and hw97 are totally different Airgun’s now he has sorted their issues. Pm if you want his number.
