case 300

[mark puttkammer]

I have a round nose, I can not find the drain plug for the
transmission, i put 80/90 in it and it is bubbling some, possibly
because there was water in it. I did find the drain in the shuttle
shift, there was maybe a pint of very thick sludge in it, do I put
80/90 in it as well?

 

[mark puttkammer]

no, i do have a 310 backhoe, the manual says 300 on it and it confused me.
I must be in a fog this morning.

Mark I use Case Hy-Tran fluid in all of my shuttle tractors as well as in all rear ends in them as well, I think they called for ATF or 10wt oil in the shuttles originally but Hy-Tran is well worth the few extra $$ it costs here is a scan from my ops manual showing the drain plug oil types and capacitys

The owner's manual is confusing. Mine is dated Sept 58, and has 300B series and 400B series listed on the cover. Several places in the manual are a bit confusing as to the volume of gear oil on a change, but I guess with a dip stick it will solve itself. As an aside there's a dandy piece of sales lit for this unit on ebay now.

I've got this piece and it's a nice descriptive brochure

yes, all this terminology like Eagle Hitch and tractor tube throw me. So do you suggest i put something in to wash out/flush what ever junk is in it like diesel and then put the light transmisson fluid in there instead of 90 weight? Is 90 wrong in the first place?

Case Nutty - Back up to page 27 in your Owner's Manual. You're looking @ the Eagle Hitch page. The utility has a different rear end assembly.

 

[Case Nutty 1660]

yes I would recommend you putting in dsl to flush also my guess is your shifter boot is bad allowing water to enter, another water entry point is the top covers I have seen repeated leakage at the speedometer cable entry point

 

[mark puttkammer]

so put 90 weight in it? Or http://www.external_link.com/en/store/travellerreg%3B-renew-tractor-fluid-5-gal?cm_vc=-10005

Eagle hitch/torque tube is the same compartment as the shuttle, the trans /rear end is separate on both AG and utility tractors I can pull out my 420 book if need be, you are correct on the industrial as many did not have Eagle hitch and or a hyd remote system, the shuttle version may take just a bit less oil in the torque tube I used this manual as it has the best pic of it and both are the same at the torque tube as far as drains except for the 400B COM has additional plugs and drain points

 

[Case Nutty 1660]

you may use 80wt-90wt if you like it will work fine, I use mine year around so I prefer to use Hy-Tran as it flows/turns much easier in cold temps

The 4 speed transmission drain plug is on the bottom of the case, just right side of center and in line with the right side axle housing. It may have a recessed square drive head that makes it flush and hard to locate. Gear oil 90 wt 80-90, Hy-tran. Capacity for 310 is about 14 qts.

Case nutty is right on the fluids you need to use in the torque tube, where your shuttle resides, although a general purpose hydraulic oil is also suitable here.

Some 310's did not have a hydraulic pump in the torque tube and it wasn't being used as hydraulic oil sump. In that case I don't see any reason you could not use 90 wt, 80-90, or hy-Tran. Your simply lubricating gear trains, bearings and seals the same as in the 4 speed transmission. The heavier gear oil would slow down any minor leaks that cause gravitation of torque tube oil into the 4 speed transmission.

At this point in your learning curve with this tractor I think you would be well advised to follow Case nutty's recommendation. Hy-Tran is a safe bet.

I have a 1957 case 310 and am also unsure of what is what. I have a dipstick in front of the shifter and one just in front of the seat. what do they both go to? I believe the rear one is for the 3-point and the front one is for the tranny, is this correct?
