Greasing the swingarm.

<< < (3/5) > >>

McCabe-Thiele (Ted):
tbh the best greasing I have experienced is when I use an industrial  one that is pneumatically powered with grease out of a drum. When using a DIY manually operated gun it's been  a very hit & miss experience for me. I've tried cartridge types with mixed results. One week a gun can be brilliant next time it's useless. An adjustable  nozzle that is the right size for the nipple head is a must so you can lock it in place. I waste more grease than I ever get into the right place.

K2-K6:
Inside the grease nipple is usually a little ball bearing backed by a spring to keep it closed and prevent dirt getting in, sometimes that can get stuck with the grease squirting outside and not pushing the ball in to open the route to the bearings. Ordinarily, leaning really hard on the gun so that it seals tight and squeezing thw grease in gets it through.

Failing that. Pushing the ball in with a small cross head screwdriver may move it.

They can also be unscrewed from the arm to inspect and clean too. Just a small ring spanner or flattish pliers to grip it and turn anti clockwise to get it out and inspect it.

Bradders:
Thanks guys. Ted I think I will have to get an adjustable nozzle as you suggest, mine doesn’t seem to fit that well. K2 -K6, I managed to get a small screwdriver and push the ball bearing in and out so I think that’s fine. If I removed the nipple could I grease the swing arm and then replace the nipple? ( maybe a daft question).

K2-K6:
Not so easy to get the grease in without nipple in place, you'd still need to seal the supply to the arm.

The nipple when it interfaces correctly (good fit gun) effectively makes a high pressure resistant pathway into the bearing cavity, the pressure is quite high as you are pushing the old grease out of the end of the bearings with the new you are forcing in, hence the demand made on the sealing as you apply it.

As already mentioned, the best fit of gun etc should make it the most effective in working through this.

Oddjob:
The 500 has push fit grease nipples on the shaft, not sure if the 350 is the same, bitch to get a new one in without damaging either the outer surface or the ball bearing.
