you took ATF... OUT... of the bike? or are you putting it in and found alum. in your old oil...??? oh I getcha now... your ATF came out dark and.... yup gotcha

 

Anywho,... I was going to say that ATF is a good choice for gearboxes or chaincases because it's not overly thick in it's cold state. Leaving most of the shavings and filings from normal wear at the bottom of the case. Oil has a tendancy to pull alot of that shit into suspension and turn your lubricant into lapping compound (not literally).

 

i would say if the shavings aren't to numerous then it's normal to see all the crap that was floating around the inside of the engine sitting on the bottom after swapping to a lighter grade lube such as ATF.

 

Further more ATF is acidic, meaning it also cleans the inside of any impurities. It also is a rust inhibitor on top of all that.

 

And it does a good job of getting into the plates when pulling the clutch in. leaving you with a smooth shift

 

 

For my chaincase in the ol' skidoo 670.... I only recommend ATF!!! :thumbsup:

 

BTW.... NEVER use lucas oil additive in your lower case! It will ruin your clutch pack. My fibers started de-lamming!

im going to do a sreach but before i do maybe someone can answer me are alot of people running ATF. and its ok to run by the sounds of it. if so that a hell of alot cheaper then belray gearsaver.

Yes but you have to change it 10x more frequently and it may not protect your clutch and gears as much. Gear saver is not super expensive compared to new gears, clutches etc.

 

For the OP, do you have a magnetic drain plug? I don't normaly have any aluminum shavings but I do get some small magnetic shavings when changing oil on my magnetic drain plug. I'd be a bit concerned if it's only people using ATF- Type F that are getting aluminum shavings! Most of the wear should not be on aluminum parts other than the clutch basket...

 

I'm not sure what the aluminum shavings would be from unless something came loose in your clutch case, or your slamming the crap out of your clutch backet or something.

Right... mostly from the sharp edges of the plates scrubbing off shavings everytime the pushrod pushes the pressure plate out.

 

if not then I'd be very worried!!!

 

As far as the longevity of ATF... I'd say maybe half of what oil has to offer. But remember that oil does not like gears. Because it breaks the molecule chains apart that give oil it's viscous strength. The elastic nature of those chains is what makes oil what it is.

 

That being said... ATF isn't the same. it is thinner yes, but it's made for super high pressure(300-400psi), high heat/friction wear for extended times. This is why you change oil every 3000miles and ATF every 100k miles. Even though transmissions don't run the same temps an engine does, that only makes it more suitable for a gearbox like yours.

 

in all fairness though both fluids get run though a gear-rotor style pump the entire time they are in motion, but the oil gets a 40-80psi boost...... ATF gets a 300-400psi shot. This has revelence because that is what is happening as it gets meshed through your gears at high speed. Also ATF is formulated for clutch packs. Oil is just made to act as a bearing surface. (at least in an engine anyways) So oil may have a lot harder time squeezing out of the plates when the clutch is released.

 

Hope I'm not to corn-fusing :wink:
