Grease port

[troasb]

Hi

There are grease ports in the Blade grip for the thrust bearings. I wonder a bit how to use them. I have the Boto greaser. Should I just press in grease until it comes out of the opposite grease port? And how often should you do this?

exactly.

I do mine every Saturday morning. I usually put 20-25 flights a week on my heli (Monday-Friday), then another 15-20 on the weekends. so about every 35-40 flights.

Wish I could fly that much

lol... Me too!

Thank you Mike. Hm, I disassembled the thrustbearings of my E5 now, after 231 flights and no grease. They were just fine amasingly, so I don't think it is necessary to do this so often, but I guess it also depends on flying style and other factors too. I am just a sport flier so I do not put very heavy stress to the machine. But it is not possible to overgrease the thrustbearings as the surplus grease will come out so it may be a good idea to do it once a week.  Also my head dampers were just fine after so many flights! (I changed them anyway)

As I had to change the clutch liner and take out the engine, I took a service on my N7 that had some 100 flights on it. Instead of dissasembling the blade grips to put in new grease, I of course would try to use the grease ports. Well I have now tried to do so with the Boto-Luber, but it is impossible for me to get in enough grease so that it comes out of the other port as I was told in this tread that it should do. I tried with all my force and nearly ruined the syringe. Anyway, I guess I have got enough grease in as it is, but I have no idea of how much grease that have gone in to the ports.

I have never been able to get it out the other side either. Just a shot in each and im good to go. I dont do it much, I would say every 100 or until its crashed

Thank you Dan. Then it is not me doing something wrong here. Greasing about every 100th flight seems good to me. But I guess it is not possible to overdo this so maybe a bit more often. Some here do it every week!

mine does come out the other side. every time. you sure they are installed properly?

Hello Mike!

What do you mean by installed properly? Direction of thrust bearings? Not much to do wrong here I think

shims. and yes, the trust bearings can be installed backwards...

[Dan Minick]

Maybe you could elaborate Mike, there are many places shims would fit in the head

Just saw your response Dan, I apologize for the slow response.

i am not sure why the word "shims" is even in that post, i must have been thinking about shims at the moment. i was referring to the proper orientation of the thrust bearings. they can be installed backwards.
