I was wondering what percentage of people did this, "The Greaser"
seems to be getting ever more popular.

Well, I didn't vote, but here's my opinion.....the bearings in the heli's are sealed for a reason....that reason being that they are creased at the factory. Forcing crease into those bearings will only serve to break the seal (that's why then, we need a creaser). I never had a premature bearing failure on a sealed bearing (worked for years and years as a mechanic). If they fail, get it out, throw it away and get a new one.

The bearings in our helicopters are not sealed they are shielded, there's a big difference.

P.S. At least the bearings in my helicopters are shielded, just thought I should add this disclaimer.

Greasing bearings

On sealed bearings, I agree! no need to grease them however on shielded bearings I grease them all the time! Same line of work...Mechanic for too long for my own good in my book Jeff.

Yup, shielded bearings need crease (I guess I should have a little closer look at the bearings in my heli...could have sworn they are sealed)..

So the pilots that grease there bearings.

How long does your bearings last?
How often do you grease them?
How do you grease them?

Do you have to take the heli apart. I have seen Alan Szabo Jr fly a Helicopter for three years and not grease the bearing and not change them with no problems.

My name is Z11355 and I'm addicted
to greasing my bearings. My life
has become unmanagable without
'The Greaser'.

The only bearings I might regularly
check (during periodic maint or repair)
are the main powertrain bearings
and mainshaft/tailshaft. The little ones
are on their own.

If you crease your bearings instead of grease your bearings you could be in big trouble....lol.....

I have noticed that many bearings(replacments) have very little grease in them....therefore I pull the sheild off and pack them with extra grease,,,,,,,,however if and when I buy a large heli I am going to buy the "Greaser"

Is using the greaser easy? I assume you still have to pull the bearings out of the heli or are you able to grease them will they are still in the frame?

Tks

I suppose I might invest in a "Greaser" then. Is it easy to get them in the UK, anyone sell them locally?

bearings

I took all the bearings ou of the blocks on my extreme and greased them, it was extremely easy once i got them out, you just take the bearing put it in the greaser and then you push the plastic piece in and it puts pressure aginst the grease to push the grease into bearing.

Some

I grease the larger bearings such as main shaft, starter/pinion and thrust/blade bearings. The smaller bearings in the head and tail I tread with a drop of Tri-Flow from time to time.

I am wondering that maybe some vendors are not greasing the bearing. Do you think it is possible.
