Correct oil ?

[Digger 66 3,526]

Hey folks , first post in quite some time .

I can't seem to find a definite answer on which is the correct viscosity for my 1972 Raider 10 8 speeds' transaxle ?

If there's any info within this site , I wasn't able to find it .

80-90 gear oil. I use Lucas, but any will do.

There are lubrication charts and those pages have been added to this file. Click on the picture and two of the thumbnails that come up are the 1972 lube charts. Click on them to enlarge.

@Digger 66  have a regular go over after every usage , engine oil , trans oil , top off tank , 1-2 oz of sta bil  fuel storage  , other related checks . agree with @SylvanLakeWH on the lucas oil , can verify the climbing  charistics , of it , for clean wall  flush downs , always clean and clear  , also  like a fresh shift boot  , underside , greased ? so it easily slides over the irregularities of trans , add a large TYE WRAP  just above boot happy place , where it wants to  stay , mine last for years  pete

Hi bud . 

It's really good to be back here . Very busy with life and finally made some time to go through the old girl .

-Drained fuel ( only a year old ) let tank dry out and blew out with compressed air .

-Made sure there was no fuel in the lines and float bowl , I ran it dry last fall .

-Changed engine oil .

-Blew out air filter element.

-Washed and re-oiled air filter foam.

I was going to change the gearbox oil but it's still very clear.

All that sounds good.

I hope this doesn't sound dumb and I'm only asking because there is another capped port under the fenders when you lift them but , is this the fill / level check ? 

It seems way too low to keep the axle seals lubricated.

No

Correct. That doesn't even get touched anymore.

 

Drain from the very bottom of the transmission. There will be a plug right near the leg of that hitch, on the bottom. Lift the front of the tractor as much as you safely can while it is draining. That gets the oil over the hump in the bottom of the transmission case.

 

 Fluid capacity is 2 quarts. Plain and simple.

Just to add on to @ebinmaine here...

The arrow is pointing to the oil fill/level check port used on Unidrives before dipsticks came into use and there was an overlap for a few years before it was removed from the casting. 

With the plug out, oil should be just about to overflow out when full. Oil level at rest inside does not reach into the axle housing but in motion, oil finds its way through the inner axle bearings and to the outer bearings behind the seals. 

You might be surprised how close to the bottom of the case the internal gears are, i.e. the lowest edges are well submerged in the oil at rest, and they are very good at flinging oil all over the place in there
