Milky Tranny fluid?

[Brockport Bill 1,413]

sorta simple, silly, question -- but when a hydo or an 8 gear gets milky fluid in a tranny from mositure -- how did the moisture actually get in the tranny -- loose dip stick or what, where, how?

Condensation

An 8 speed shifter acts like a wick in wet weather - rain trickles down the lever, by the less than tight fitting boot and says "Hello" to the 90 weight. ALWAYS keep the Horses inside or covered when not in use.

@Brockport Bill  usually its the cracked rubber shifter boot , regularly check all of mine , also use a  vinyl / rubber treatment on it to treat the rubber . always have a spare in my w/h parts , when you start the drainage and  flushing on that , or me its typically a  2 times  drainage and flush , to really get out the moisture , and debris. do you have a near by empty road or private drive ? i road time the oil , for a heat up and drain , then do a fuel oil or atf fluid refill for the drive / flushing action . then back to lift up the front end of the ground to increase drainage . others will also respond to this , but a thorough drain/ flush is what you want before a fresh  80-90 refill . pete

Pete - I have always enjoyed your comments about the tranny flush routine -- actually i have passed on your knowledge to other WH folks as well --- they routinely comment about having done so and how well it worked ---- and yes, i have a new boot on my 312-8 -- but its always indoors storage so that helps -- Could you clarify the tranny flush for a 8 gear, versus hydro regarding using Kerosene or diesel etc? thanks

ahhhh -- makes sense

Do not flush a hydro with anything!!!  Just change fluid...

[Maxwell-8 4,271]

I have open a couple of transmissions, all had rust on the inside, the top side more specific.

@Brockport Bill  have to agree with @pfrederi  on the hydro, just change fluid  . the 8 gear , works best when its clean oil fluid , usually 80-90 wt . if the oil is warm it drains better ,and will take more debris with it . jacking the front wheels off the ground , about 6" with jack stands will help the drainage . I refill 2 qts  of atf oil or diesel fuel , drive it around and use hi/lo range and every gear , you could even fill it at the shifter boot area , that will help clean out the rail shifter . usually 2 , flushes cleans up the debris , then fresh 80-90- gear oil , 2qts. also lubricate related clutch pedal linkage , for easier shifting , replace shift boot . there are related pictures on site  of this service , pete

Which machine has milky oil?

Also, don't flush a hydro, just change fluid.

A hydro filled up to the mark on the dipstick has a very small area not filled with oil.  Also no big openings to the outside just a tiny breather in the dipstick (sunstrands).  A gear drive is 75% or more air with a big opening for air exchange (gear shift). That is why condensation and thus water contamination is not as big a deal in hydros...

And the inside of the 1100's are painted. A lot less surface area to rust with most of the gearing is under the oil.

 

I know one place people over look when it comes to water in oil..... the original packaging. Back in the day I had an issue with water and it was in the 5 gallon cans we purchased. The cans we stored outside in the weather and the sun would expand the cans. And if it rained there after, the can would slowly draw the water laying on top down inside through the pour spout.

Good Point I forgot Sunstrand transaxles are painted also...

@Brockport Bill  never did a hydro trans drain / refill, so I  can only refer to those that are experienced with it , my regular routine after usage is to , always check trans oil / statis , always add STA BIL to my fuel top off , general kook around , or  go after anything that has shown up . the time to look for stuff is when you are running solid , that way you will probably find something out of whack, make sense ? you had no problems , but suddenly started to surge /  skip /  not charging ? that time period lets you quickly zero in on it , all of mine run /  operate the same way , so if anything is off , I  am on it , pete

Did this 502 4 speed prior to opening it up to change a bad 3rd gear. Same can be done using a complete tractor - drain the oil - elevate the front off the ground a foot or so while draining. 2 quarts of diesel go in with tractor level - run thru all gears and hi-low for about 10 minutes each. Drain and look at what comes out - if still rusty, repeat. Two flushes should do it. Check the 4 seals to see if they leak, as diesel is a lot thinner. Change the seals and the boot if needed...
