Thread: What grease gun to get?

Has anyone had any experience with these?
I'm assuming they work with the standard grease nipples / zerk fittings?

Yep, the long needle works well at getting into the centring bearing on a DC shaft on a Deefer, although you still need to pull the floor out to do it.
They also work fine in a standard nipple.

TA, Bearquip have the needle point on the shelf, and if you see Greg tell him Rick that used to be from Murrurundi says G'day.

I will do Rick, thanks for the tip off. Cheers

As Rick130 said I was always told by numerous mechanics to pump until purged, not keep going but listen for psst as it pushes out and stop, pushes out the crud from the seals. However too much can damage seals.
I have had 2 cheap grease guns for years without any dramas but also have a compressor gun, that I have never used as it takes an odd sized cartridge.

Ended up picking up some of the needle adaptor fittings for my mcnaught gun. Have not yet had the chance to use them, but I will mention that the longer needle adapter pictured above has a much finer point which is easier to get into the ball detent of the zerk

Sorry to exhume this thread, but no grease gun threads I found answer the question about whether a high pressure grease gun (~10000psi) is suitable for greasing uni joints, ball joints etc. on a defender.

Haynes manual calls for a low pressure gun for uni joints, so I want to know if a high pressure gun can be used without damaging seals etc. Cheers!

Depends entirely on the operator...

If it's possible, change the setting over to low pressure-high volume setting.

Try to work in a low noise environment and slowly pump the gun until you hear the popping sound of air escaping past the UJ seals and/or if you feel resistance
against the grease gun lever.

'Less grease more often' is the preferable way to grease rather than pumping away furiously trying to replace all the grease in the UJ.(and risk popping the seals in the UJ's)

You'll only reach high pressures if the grease has nowhere to escape.
As already mentioned, listen for the noise as grease escapes or look for it.
I don't think you can damage seals in UJ's by pumping grease past them.

I always used a HP grease gun but in recent years reverted to an old Tecalemit gun that used to come in toolkits with British cars & motorcycles.
