These Planetary gear fluids should be changed yearly at the very least . There are quit a few comments on how tediously this job is . The 85 w 140 flows like molasses in a cold shop . Original idea I heard from dealer tech ( Bill @ Veseys ) and decided to make something using his idea and ideas from Golftechs .
The plug holes ( 4 of them 2 inside and two on the out side facing you ) are 7/16 - 20 thread . Pick up theses at Lawsons
The 1/4 brass nut will work ok . One end has seat .Making up a double flare line . Double flared not so much for pressure but needed a bump out so nut will seal it up easily against fitting .
For guys that haven't made proper brake lines this is how its done . Cut pipe length you need . Bore out hole a bit otherwise you will have a bugger of a time getting the double flare tool out .
Put it in holder (1/4"in this case ) and flip double flare tool upside down as a guide for length sticking out of clamp .
Flip flare tool over and put in tubing .
Press it in till it bottoms out .
Pull tool out and you should see a near perfect start to your double flare .
With out tool press in again a bit to flatten it out .
And done . If your making brake line I would advise to put your fittings on first . Lol you'll know why .
Lightly clamp in vise
And snug up .
Here is my gizmo with pipe I just made attached . Yes its a spaghetti Jar . I'm going to keep an Eye out for a jar with a sturdier lid . I drill 2 holes in top a couple of sizes smaller than hose I'm using . One side with tubing will go to near bottom of jar the other just has to poke through a bit .
A test run ....works perfectly .
5 psi was enough to move that thick gear oil easily . Wouldn't hurt to warm the gear oil up a bit before starting .
Draining the outside .Drain plug should be straight down leaving the other plug at the 3 or 9 o'clock position .
Then the inside . If your in a warm shop it shouldn't take to long .
There are access holes to get at the 3 o'clock plugs out on the inside
Filled my jar up with 85 w 140 then keeping the pressure on at 5 lbs waited for it to come out the 3 o'clock hole . The instructions are vague in the operators manual you have to do this to both sides . If you do just one it won't have the right amount of gear oil because it takes a long time for oil to transfer itself to the inside. You can leave the plugs out on the inside it will be barely trickling out when your done this side .
On to the inside ones . See barely any coming out .
Hooking up to bottom plug on inside
Then after it seeps out put plug in and let rest of pressure out on pressure gun . You will loose a little when detaching this time so be ready with plug .
Just another picture
Toro had to get me this spacer on one side of machine . Park brake wire was rubbing on tire till it popped .
All done . check for leaks and just snug all plugs in . Warm shop and warm oil after tools are out maybe 10 minutes a side easily .
I had also tried to vacuum oil in from 3 o'clock positon sucking it up from bottom but found it took to long .
