Case 930 Comfort King help

NayNay · Jul 7, 2014

New to the forum and hoping you guys can help me out.

I recently bought case 930 comfort king (not sure on the year) from my father in-laws estate auction.
I want to change all the fluids and filters before I do anything else with the tractor. From what I've found on the internet the fluids are as followed

Crank case- 30w 14 qts
Transmission- 16 gal of 80/90w gear oil
Hydraulics- Hy-Tran 14 qts

Do the hydraulics and rear end share the same fluid? And would universal tractor lubricant work instead of Hy-Tran?

Where do I fill and confirm level for transmission fluid?

Where do I fill and confirm level for the hydraulics?

Thanks in advance for help!

Site won't let me post pics yet for some reason?

You are on the right track if you have a 6 speed tractor. If you have an 8 speed we need to start over.

Its a 6 speed.

You can get an approximation of the year of a 930 CK - if it has round orange fenders it's 1963 to about 1965, tan fenders are 1965 to 1969. If you post the serial number someone on here should be able to give the exact year.

The first 930's used 80W-90 gear oil in the trans/rear end but by the time the CK's came on scene in '63 I think Case switched to Type A atf oil which was also originally used in the hydraulics. Hy-tran is a good substitute. You'll be able to tell what oil is in the rear end as soon as you drain it.

The oil for the motor depends on temp range it'll be used. I run 10W-30 in my 930 because it gets used year round.

Might set off a firestorm, but the best 15W40 is superior to SAE 30. SAE 30 is all they had in the early 60's. Also, 85W140 is superior to 80/90 Gear oil. Hy Tran or a similar "Transmission-Hyd. Fluid offers the best protection for the hyd. system. Good luck.

I'll second that! Never use anything lighter than 15W-40 in a diesel unless you are in extreme cold. 85W-140 helps loud transmissions quiet down also.

Don't want to stir things up but-- I think that is a plain 930 NOT comfort king according to pictures above. If teh pictures are of your tractor. Serial number should be on right side of dash.

Jim in Sask · Jul 7, 2014

Len is right, that's not a Comfort King - they had the fuel tank behind the seat. It's a 1961 or 1962 because it has the longer nose (1960's had a shorter nose like the 900's), and the fuel tank cap is also different from the cast one used on the 1960's.

Here's some scans from my owner's manual about the rear end and hydraulic oil fillers and level plugs.

NayNay · Jul 8, 2014

Thanks for the manual pics Jim.

It's very faded but it does say comfort king on the engine hood. Maybe someone put a comfort king hood on this tractor?

Am I to understand that the transmission and rear end share fluid from the same reservoir and the hydraulic reservoir is just for the hydraulics?
Just want to make sure I have all my facts straight.

Yes, the hydraulic system is separate from the transmission/rear end and on mine at least use different oils. The trans/rear end is a singular unit.

Noticed you're Canadian as well, which province if you don't mind my asking?

NayNay · Jul 8, 2014

I live in Alberta, Red Deer area. My father in laws farm was just south of Alix if your familiar with the area. He was a case fanatic, and here is a pic of about half of his tractors getting lined up for his estate sale.

Jim in Sask · Jul 9, 2014

Your father-in-law had very good taste in tractors!

I'm orignally from east central Alberta so I'm fairly familiar with that part of the province.

I have an early 930 that's been in my family since new. While yours is a bit later I think most things are similar. When you change motor oil, besides the oil pan plug there's a pipe plug on the left side trans housing just behind the oil pan that should be drained. Also, your fuel pump may be like mine in that it's lubed separately - there's two small drain plugs under the pump body, 7/16 wrench. The filler cap is top rear of the pump, pour in a bit of motor oil, only a few ounces, the excess will drip out the pipe on the side of the pump. They changed that by the time the Comfort Kings came out, using the engine lube system for the pump.

It's best if you get an owner's manual, should be some on ebay.

NayNay · Jul 9, 2014

Thanks for the tips. I assume the pipe plug behind the oil pan is to drain the clutch?
I will order a manual once I get the serial number and find out exactly what year/model my tractor is.

Jim in Sask · Jul 9, 2014

Early 930 serial numbers:

1960 - 8160001
1961 - 8168801
1962 - 8190001
1963 - 8208001 (start of Comfort Kings)

Despite the hood decal your's is pre-CK, all CK's had the platform higher and ahead, you climbed on the platform in front of the rear tire and the fuel tank was behind the seat. The manual you need will say "930 Diesel Wheel Tractor". The CK manual has Comfort King in the title. There's enough differences between the early and CK models that the CK manual might have wrong information for your application.

NayNay · Jul 16, 2014

You were right about my tractor being just a 930. Not sure where I seen the comfort king name, but it wasn't on this tractor.

And now that I look it's pretty clear where the fluids go lol

Judging from this pic I will assume that I have the injector pump thats lubricated from the engine oil.

Jim in Sask · Jul 16, 2014

So it looks to be a 1961 model. I wasn't sure when they changed the pumps to the self lubing style like yours is. Looks to be in good shape, hope it treats you well.

NayNay · Jul 17, 2014

Any idea where I could find a used loader for this tractor?

Jim in Sask · Jul 17, 2014

A good place to look for a loader would be Gratton Coulee Parts (www.gcparts.com) up at Irma, Alta., not that far from you. Their website lists used equipment they have for sale. I know guys that have dealt there and speak well of them. Also kijiji is worth keeping an eye on.

I have a Leon fel on my 930. A lot of people say a hand clutch is a misery with a fel but I've gotten on well with mine for years.

NayNay · Jul 21, 2014

I will check them out. Thanks again!

Yeh hi just wondering if you or anybody knows about drawing the clutch.
My 930 ck pushes a fair bit of oil into that area, and I'm not sure if this is normal or what.
We just replaced the clutch plate, and the pilot bearing was gone as well. But when we worked on it we noticed it and a strange type of lube setup from the engine. What regulates the amount of oil that enters the couch area
