Volvo EC25 Grease nipple leaking

[Richard14]

Hi
The Track Ram grease nipple is leaking, I Have changed it several times but still comes past the ball bearing. Any suggestions?

Best guess is a bad batch of grease nipples.
If the ball seals properly, the nipple should burst (pop the ball out) before it leaks - more pressure = more sealing force.

As a simple test, swap the nipple with another on the machine from a similar location - see if the leak follows the nipple or stays at the same place.

It started with it blowing the ball bearing out of the grease nipple, since that i have swapped it with 3 others and it still leaks grease past the ball bearing, I will try with one already on. Thanks

Do you think it could be the grease? I use 2ep.

The grease nipple can't hold the pressure there will be another pressure valve that is leaking

Thank you

my second best guess is there is too much wear in the bush and the pressure inside gets too much due to the slop.
I assume the grease is oozing out as you work rather than simply leaking as soon as you remove the gun?
(nothing wrong with the grease you are using)
