Gearbox lubrication/grease

[Waggie]

Help. I have a Stihl FS76 strimmer/brush cutter. I need to change or top up the grease/oil in the bevel gear box, I have done this several times in the past, but when I went to order a tube of grease from my Stihl agent he informed my that the cost has gone up to over £10 for a 80gram tube. What a rip off.

Has any member any suggestions for an alternative product??

I just use Lithium grease.

[doobin]

Any grease will do.

i unscrew the plug and fit a grease nipple instead then just a pump from the grease gun does it just nice.jake

Brilliant suggestion I think that the way forward.

I have seen adaptor plugs that do have a grease nipple set in to a plug that simply screws in to the original hole. You just take one out, grease and then swap back - they were on ebay.

 

Grease wise - the destroyer of gearboxes is LACK of grease and any gtease is better than none but Lithium HT grease - the type you pack in to wheel bearings will be fine.

Any ideas as to the thread size for the gearbox plug, I will need to get 1, I don't want to guess the sizes nor purchase a selection of sizes, any help would be welcome.

if you have the plug already drill a 5mm hole in it tap it to 6mm and fit a grease nipple

Just take the plug to your nearest agro engineers and they will sell you a greasenipple to ffit.I have a selection box of nipples and just match the thread size.Jake

The Stihl grease will be just lithium EP2 almost guaranteed. Maybe a lithium complex high temperature grease. But a 400 gram tube is £2-£3 + vat. So a bit better than a tenner.
