    Posted: 19 Jan 2010 at 5:26pm
I was told that my WD requires a special hydraulic fluid due to the pump type. I was wondering if this was the case and what type of fluid I need. If it is an unusual type, where might I find it? I checked my level today and I am way to low.
Thanks in advance.

Brian....Non Detergent straight weight.  I generally have used 20 year around.  If I need to add in the winter, I add #10 and #30 in the summer.  # 20 seems to be harder to get in some areas.  I think some are even using universal hyd....Dale

If its way low  and you don't know whats in it now, don't add to it , drain and refill . The  operators manuall calls for SAE20 above 45  or SAE 10 below 45 degrees.  Capacity is checked with the rams extended. I would use a good quality Hy-Tran fluid  .You do have an operators manual?, don't you?

No I don't have an operators manual. I was given a service manual but I was unable to find the fluid type.

I would agree with Gary, drain it and fill with hytran fluid. It is much more available and much better oil than the straight weight oil recommended 50 years ago. Any Farm store should have it and I think Walmart even has it.

There should be a 1/8" pipe plug on the bottom of the pump. Drain that too just to insure any water or condesation gets out of there.

  Good point , Rick, I forgot that.  Roughstock, if you go to the top of the main page and click on Allis store , the dude that owns this site will sell you all the manuals  you need for a small fee, it helps him keep the site going.   Gary

I use a universal hydraulic fluid from Wal-Mart in my WD. Works well, inexpensive and convenient. Been using it now for 3yrs, and this year was my first year to use the WD for pushing snow, we're talking about single digit temps and no problems with my hydraulics at all. I was so impressed and proud!! Good luck Roughstock, and I also purchase a manual from this forum that is very helpful along with all these wonderful people providing advicel.

Now I'm confused. The last post said hytran in the rearend. I have drain plug under the gear shift (with a fill plug on the side). I put gear lube there. there is another plug under the rear axle (but no apparent fill point). Is that all gear lube?

The trans and the hand clutch/hydraulics are separate. The trans takes 80-90W. The hydraulics gets the hy-tran.

What is the purpose of the 2 drain plugs--one in the axle and one for the tranmission, but only one fill point ( below the gearshift). Do they have the same reservoir but separate drains?

Here looking in from the rear with rear end out, you can see the reason for needing two drain plugs but only one fill hole.  The full level is well above the pass through holes, but to fully drain there needs to be a drain on either side of the wall.  Tom

The differential and the transmission are 2 different castings. If you only drain the differential you will have old junk still in the transmission that will be mixed up with your new fluids. You don't need 2 fill holes cause the fluid will run to the differential. That is part of the reason I drained everything and fill everything with hytran fluid. Hytran has worked well in my diff. since 1983 with no problems.

Roughstock, When we sold them we used SAE 20 non-detergent oil.  Worked fine.  That said I have heard good reports of the "state of the art" hytran fluid.  I did see some 20W at Tractor Supply Company.
Good Luck!
