Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I tried to find it but could====it was a discussion about oiling the foam precleaner.    Brigg,s recommends oiling---Tecumseh does not.   What are your thoughts of this?  Who is right---Brigg,s or Tecumseh?   I want to believe Tecumseh-- for oiling makes for a mess and I am not too much on washing in soap and water and reusing.  I usually replace.   On my TVT-691 Tecumseh I merely blow it out  from the engine side and reuse it usually for a season and then replace>(sometimes both filters) Appreciate your thoughts on this subject.----Your friend Will

Will,
I dont really think that it matters all that much if you oil the pre cleaner or not.
I look at it like the pre-cleaner is there too collect the big "chunks" of garbage and the paper is there too get the little chunks.
I understand that the pre-cleaner is there too save the paper element from overwork....but at what price? The fine stuff still gets thru too soil the paper element. Oiling the precleaner just plugs the precleaner up faster.
Briggs even gives instructions in the box that they package the pre-cleaner element in......that if it is used on one model, then oil it. If it is used on another model...dont oil it.
The purist will villify for this....but if you have an air compressor....dont oil the pre cleaner and blow them both out with compressed air when they get dirty. (Not once every 3 years but when they get dirty!)
Save yourself some bucks and and use a little old school common sense. Micro-dirt doesnt kill these engines....outright abuse is what does it.

I dont oil my pre filters on my OPE, HOWEVER, aon my engines for my airplanes and RC trucks I do.  Some of these engines cost about $1,000 each, and one spec of dirt can ruin them.  ALL of the manufacturers of them I have ever owned has specific instructions about oiling them for maximum cleaning effectiveness.  My understanding is the oil helps catch the dirt more, and holds onto it.  Think of like a sliding patio door, if you oil the track, you catch all the crud building up on the track that prohibits easy sliding of the door, so instead if you use like graphite, it will lubricate W/OUT collecting dirt.    In review I would say if you want to catch the smallest of micron dirt particles, use oil, if you dont some may get by, BUT in an engine of that size/strength, I doubt you'll do any damage to them.  just my 2 cents. 

Will, if it says not to, then don't do it.

My Kohlers manual says to oil the foam pre-filter but, you only oil it so very slightly. If there is a mess, you used too much oil and it could be making it tougher for the engine to breath. Like Lint suggests, it probably doesn't make a lot of difference. But, I would rather catch as much as I can, within reason. If you can squeeze the foam and have oil bubble up, you used too much. I think my Kohler manual actually says to not use more than a dime or nickel size amount in your palm and rub (kneed) it into the foam pre filter.

I think I read something somewhere in the thread about oiling paper filters. Nope, no do dat! The K&N Filters for cars, trucks, bikes, etc, are a cotton/gauze material and oiling them really helps filtering but again, lightly.

Anyway, it's what I do, right, wrong or indifferent.

Thanks so much everybody---You covered the subject so  well. I Am a maintenance fanatic so I will probably keep servicing like the eng. manuf. advises.  It is so true what several of you stated---the precleaner is there to stop the bigger stuff---if it is oiled it no doubt will collect more, but is more messy to handle.  I do however believe, if you will check and clean every 25 hours, (either oil or no oil on the precleaner) you could get a lot of hours out any engine.   The problem I have seen over the years is the fact that most people will not  change oil or clean the air cleaner and maintain them properly.    They just keep running until damage is done..  Thanks again, all of you and may the God of this world watch over you and your family, now and always.     ====Will

Bill_D I too oil all of my $$$$ RC engines!

And this is why the filters are soooo important!

And I also going to try and keep my OPE stuff oiled where the manufacture calls for it. I have heard of people using WD40 but that seams way too thin IMHO.

Brian awesome trucks man!!!!!   I love that wheelie bar on trhe one.I have a savage all decked out w/ aluminum parts, and a .28 Rossi.  Helis are my main thing rite now.

Heli's rule! I havn't gotten into them....YET! Savages are a great truck too...don't have one yet either...

Brian---That is some truck--I would just about need a ladder to get in it.   Beautiful pictures --know you are proud of them---Will

Brian, Bill,I often wondered if you can run those through dirt, but how about water? 

Ajace, they tear through puddles and stuff, but if you get in water to deep(about 4" or more) and you'll suck water through the air cleaner assembly and stall it.  Now, you would have to be driving for a long period of time in the deep water to do so, a quick dash accross it will not get sucked in, but true submersion of the air cleaner assembly will allow water to get sucked in.  these trucks are amazingly durable, and fast for their weight.  I have literally jumped mine onto my house, and then driven off the other side of it, landed like a cat and peeled away laugin' .  Rite now my savage has a .28 engine, and is geared w/ a 18/49 clutch bell/flywheel, and will do about low 50's mph.  There is a truck called the EK2 that I have seen geared to run over 90 mph.  They are a riot!!  I currently invest most my time w/ my helis.  I'm flyin a Raptor 90 class.   I have sooooo much time invested in learning to fly these things, I would be embarrassed to admit.  I can now hover and fly around my front yard like a pro.  but nothin like some of these guys do w/ flying inverted and such, not yet anyways.   I also just got into E-Flite sailplanes, and I think it may be my favorite of all.  I have a 3Meter wingspan sail plane that uses an electric motor to climb it up to about 1,000 feet, then you kill the motor and just glide, and catch thermals.  It's amazing, I had a flight of over an hour 2 weeks ago, coulda gone for alot longer, just my neck was to stiff from looking up to keep her aloft any more.  Planes are EZ to fly cause they are built to fly.  Helis on the other hand, whoever invented them musta been out of his mind.  They dont want to fly, you have to force them to.
