Could someone explain the proper way to grease the bearings during the build. (IE. Triflo Grease vs. Triflo oil. The Greaser?)
Thanks

It's kinda funny. JB puts that pro tip in the manual, and suddenly everyone goes out and buys a greaser and has to grease their bearings. Truth is, you don't have to do that. It's a nice thing to do to increase the longevity of the bearings, but even then, you're going to take out those bearings in a crash before you wear them out due to the poor quality of the grease. My pantera has been flying for a couple months now with the original grease in the bearings, and they are fine. My Evo flew for 2 years, with god only knows how many gallons (certainly in the triple digits) through it with the original bearings and grease. Basically, if you want one more thing to do, go buy a greaser, they are a cool little tool. But you'll most likely end up like everyone else who buys one, use it a couple times, then it ends up in the pile of cool tools you've bought and never use.

If you really want to, go buy the Greaser, it forces grease into the bearings. But, like I said above, there really isn't any need to.

eurylokhos,

Speaking from personal experience? I can safely say that I still use my greaser all the time. And not just for hobby related bearings either. That "like everyone else who buys one" statement is just a bit strong and totally unproven.

My heli's have been flying now for 3 years, NEVER greesed any bearing other than thrust bearings, I put a drop of triflow on them when I build them and that's it, they tend to spend more time in the air than on the build table other than routine maintenance.

Of course where we fly is a nice grass field, no open sand pits so we don't get alot of tiny debris that would normally cause your bearings to pick up the dust and such causing wear.

Yup, I can't even tell you where it is. Somewhere amongst all the other cool, but ultimately worthless things I've purchased for this hobby, like head loaders, paddle gauges, specialized flybar locks for helis I don't have anymore, etc etc etc. It was cool the first couple of times I used it, then I realized that there was no real benefit to having done it, and stopped wasting my time.

Bearings do need grease. It's just a matter of, if you want to do it yourself, or trust someone else to do it.

It don't matter how you get there, if you don't know where your going.

Where can I get that sticky teflon white lithium grease? I would like to use it on thrust bearing packs.

Not the spray can crap. I'm looking for a tube of high quality stuff.

You can use Tri Flow on all the bearings.
I did that with the Tiger for the last year. 7 gallons, and some trashing of the bird.
Yet I just got my Greaser. So durring my Pantera build I'm greasing everything on the new build.
let ya know.

My Tiger 50 is at 16+ gallons as of last Wednesday and generally flies off grass with occasional landings/low/slow fly-bys on the dirt runway.

I too just received "The Greaser"...from reading the Pantera manual (my ship arrives Monday...hmm work...or stay home?).

I'm going through a general over-haul (dish-washer) of the Tiger now that wintertime is here in Indy.

All bearings within the Tiger 50 spewed out dirty black grease when I ran them through "The Greaser" before the clean white TriFlow grease passed through.

Of note, I have a second Tiger 50 Kit that is for spare/spent/bent parts...I pulled c-springs and dust covers off the bearings (that could be accessed)...all have enough grease from the manufacturer to run what I'd consider a reasonable life.

If you throw "greasing bearings" into a search-engine... I think you find enough information to become your own local expert and take it to the level you desire.

The bearings definitely have a bit more resistance to rotation once loaded with new grease.

I have a small concern of packing too much grease into a bearing...the greaser really fills the voids...but I'm betting on the first run after the rebuild the bearings will spew some of the excess grease out and return to a happy equilibrium.

This is a hobby and I like to split hairs with an axe…so “the greaser” will be part of all my bearing maintenance schedules/builds…nothing quite like a smooth & trouble-free flying bird.

Grease is made of soap and a thinning agent. Solvents evaporate from non sealed bearings leaving a material behind with poor lubrication qualities. How long has the cheap little bearing been stored in an unsealed package, was it actually greased correctly at the factory?

The guys not greasing may use oil on a routine basis which can be messy. Since you have to remove the grips to lube the thrust bearings why not do the radials while you have access?

When you know the bearings have a good load of grease and you have glitches, they can generally be eliminated from the troubleshooting process.

The other alternative is to use rubber sealed bearings in trouble prone, high service areas (mast, grips, and clutch bell maybe). Bearing life also depends on how hard you fly the machine, how often and general model care. Fair or unfair, when I see a dirty scuzzy model I sometimes form a mental picture of a modelers living space!

Give you an update...

After running all the bearings through 'the greaser' and rebuilding the Tiger 50...she was a bit stiff before running the engine.

After 1 tank of fuel, all things spin/rotate freely again.

Just as easy as all the extra grease went in... after getting up to rpm the excess was expelled.

Seesaw & mixing arm bearings, Grips (tail and main) all seemed to expel due to centrifugal force. Tail pulley output shaft, main and clutch bearings from internal centrifugal force from their operating rpm's.

Smooth and quiet…best build yet for this bird.

I'll still Triflow the links...but the bearings are on a new schedule...after crashes or case (or 2) of fuel.

Grease On!

Dude II,
Did you type that your tri-flowing the links?
Ball Links? Never thought you should do that.
Grease on!!

Billm,
I've tried half a season without tri-flow on the links...the most recent half with tri-flow on all ball-links.

Wear seems to be about the same...but I also replace links at the first sign of excess play.

I tend to lube the tail assembly less now that I'm flying several minutes inverted on each flight...exhaust keeps the entire tail wet...only after rebuilds or deep cleaning with the spray bottle/compressed air.

Dust and grime inspection of the "wet links" seems to be pretty clean (grass field take-off and landings 95% of the time).

I lube my ATV, tractor, lawn equipment & bikes...so the heli gets the same treatment.

I sleep better knowing that their wet...if the OEM says "not needed"...I suppose I'll re-direct the savings in Tri-flow to some other area of the bird.

You really don't want to oil any links as it will tend to attract airborn particles and once they get traped it will be like sand paper and slowly grind down the plastic causing the links to loosen up. On a glow machine they tend to get misted occationally if you fly backwards and the exhaust gets into the canopy.

Fox,
Thats what I thought as well.
If anything. I pull my links off every so often and clean them just to keep the "sandpaper" cundrum out of the picture.
