TriFlow available in India ?

second_chance

unfortunately, not available in india  :(

Would love to get tri-flo....sounds wonderful.
Again, not to get into a debate, I've been using a dab of WD40 followed a few moments later by a clean-up with a soft knit fabric and then light spray of silicon lubricant with great results. Seems the tri-flo would do all that at once!!

It is something that is always in the field box.  Bottom right corner of the yellow box in the picture below.

Anwar, you seem to be using the triflow dry lubricant. As from what I can gather from the internet, this thing is liquid before but dries up to grease like consistancy soon. How long before it dries up? And can I use it on bearings? will it penetrate sealed bearings before hardening? I have a feeling that the bearings on my MT needs a lot of lubrication and cleaning.

I have 3 options:

TRI-FLOW 2oz Superior Dry Lubricant

OR

TRI-FLOW 6oz NON AEROSOL DRIP BOTTLE

OR
Scorpion Motor Bearing Lubrication Kit

Which one do you guys suggest for general purpose bearings?

anwar

Nope.  The dry one is this :

What I have (same as Chand/second_chance, I believe), is this :

Similar packing/bottles, only subtle difference in label colors :)

The image might be different but they all tend to be the same, as the triflow website does not describe any other product, BTW that does not answer my question regarding time required to dry and usability on sealed bearings.  ???

anwar

I guess the question about drying time (and hardening) is no longer relevant, as we are not using that type.

Regarding bearings, except for the main one way and any thrust bearings, I have been using the same thing.  They don't do any harm to sealed bearings.

Interesting. I was just revisiting this thread. Got back from US and got some Triflow lubes.
Now, looks like everyone is using http://www.triflowlubricants.com/Tri-Flow_Superior_Drip_Lubricant.html one.
I also got the dry lubricant, and that is : http://triflowlubricants.com/Tri-Flow_Superior_Dry_Lubricant.html

Wonder if the dry one might be better to use on the main / tail shaft ? since it will not attract dirt ?
I got both, so was debating which one would be better to use.


vinay

I have also ordered the dry ones. Its on the way. Iam thinking dry ones to be better suited for bearings. What I noted was that when I used the normal triflow, it actually removed the grease from the bearings and made the bearing balls loose and clicky. Not a good thing to happen. Hoping the dry ones(which becomes like grease after drying) to work well with the bearings.

anwar

If a bearing becomes clicky, it is dead and the solution is to remove it. It is not something that can be fixed via lube/grease.  Lube/grease can help prolong the time required for them to go bad/clicky.

Unless you fly as soon as you apply this lube, dust is not a problem. After a little while, you cannot really see any of it left around in clogs that will attract dirt/dust.  It is a problem mostly for grease.

I have been using the regular one on bearings for a while.  The the bearing that always goes bad first are the ones in the head, the ones through which the feathering shaft passes.  It is a testament to the kind of load/tension being applied on those.

for thrust bearings use silicon grease made by anabond - available in delhi machinery markets - delhi machinery stores in chawri has it

What grease or lubricant should i use for the HK450 heli's.
Is there any special grease or can i use a normal one?

i only grease thrust bearings, i use normal ball bearing grease for that

i am not a grate believer when it comes to add oil on helis, i fly in cold and warm climate and even dry oil have coursed problem for me

i make sure main shaft and spindle for tail is clean and i do that with a 2000 grid paper just to take the oxide away

sealed bearings i never oil, if oil is thin enough to get in it will wash the grease away, ow i never oil

some people oil motor bearings like on the smaller scorpion motors 3026 and down because of the internal heat but ever there i do not oil, with right gear mesh i i still get 200+ flights, normally bearing goes anyway if i strip a gear

Merged the last two posts into existing topic on greases for helis.

I am not sure what the locally available greases are... as you can see in this thread, most people are importing.
