Danuser F8 post hole digger seals

I have a Danuser F8 post hole digger that needs the two gearbox seals, one at the PTO/pinion shaft and one at the 2 9/16 auger shaft. Does anyone have a number or cross reference number for these seals other then Danuser's number?
If you also have the gearbox bearing numbers, I would keep for future, but seals # I need.

If you are capable of measuring the bore the seal fits in, the shaft diameter where the seal rides, and the seal width accurately you can plug the numbers in at the link below and get a SKF/CR seal number that most any auto parts store will have, or be able to cross to the brand they carry or quickly order you one. Or, if you have a local industrial supply "bearings and drives" sort of place, give them a try.

a F8 DOES NOT use oil but corn head grease for lube, someone added oil that is why it is leaking they would leak bran new if you put oil in them,, I sold Danuser for 30 plus years,, cant even begin to say how many times I heard this in the last 50 years,
cnt

I know what oil to put in, my question was for the cross ref. seals not the oil. I also know the Danuser number and price of their seals.

Thanks for answer. I can get the exact bore and shaft sizes for both, but both of these have some kind of material inside that is part of the seal, so they are of a design different then a seal backed by a spring, and they have no numbers on them. My guess is they are original to the gearbox. This is why I'm looking for seal numbers other then Danuser.

The Chicago Rawhide numbers are 25597 and 16406.

Wonderful news,,

Thanks a lot Shaun, I'll look the numbers up.

In my response to finding SKF seals you wrote: "but both of these have some kind of material inside that is part of the seal, so they are of a design different then a seal backed by a spring, and they have no numbers on them. My guess is they are original to the gearbox. This is why I'm looking for seal numbers other then Danuser.

So Shaun gives you SKF/CR numbers for "off the shelf" seals, for which you are thrilled/grateful, likely the same seals you would have found by dimension with the "Sealfinder".

I must have missing something here???

Well, not sure. I looked up the CR seals and one looked good, the other looked like a regular oil seal. Remember, these are GREASE seals not oil seals. I did measure the shafts and bores and the following size seals should fit: Pinion -OD 2.875, ID 1.635(probably 1.625 seal), Auger - OD 3.500 ID 2.562. These would be the OD and ID of the seals. Now, if I can only get a cross reference GREASE seal number for each.

Either seal will work FINE for "grease".

The 16406 is a CRW1 series seal, 25597 is a "CRWH1" series seal, meaning that it has an extra steel stiffening insert, sealing lip and "garter spring" are basically the same.

Looks good, I'll look into these. Thanks for
the info.

For anybody out there that has an older model F8 (or maybe F7) Danuser post hole digger, the original oil seal numbers are: Auger - Garlock Klozure 63 x 1885, Pinion - Garlock Klozure 63 x 0787. They are still made and you probably can cross reference for a different brand. According to Danuser one of the seals is obsolete to their part list, don't know why. Just see if the bore and OD are the same as yours.

I am rebuilding an old, recently acquired F8 with new bearings and seals. In researching the lube requirements, I came across this statement on the Danuser website: [b:deac1c597c]"...you will need to add 3 lb. of Shell Alvania EP2 Grease (old name-Texaco MultiFax-EP2) or equivalent. DO NOT ADD OIL TO THE F-SERIES GEARBOX."[/b:deac1c597c]

What it doesn't say is what NLGI ## to use, ie 1, 0, 00, 000, etc. I've seen "cornhead grease" listed as both 0 and 00 consistencies. I'm thinking that using the thicker 0 would be better for me in Georgia due to the heat. With your long history with Danuser products, do you remember what grade they originally used?

According to Shell, the Alvania EP2 grease was replaced by Shell Gadus S2 V220 grease, and they list Grades 00, 0, and 1 as suitable for gearboxes.

What was left in my gearbox when I opened it was a semi-fluid brown grease. It SLOWLY poured out when draining it. There was some water in there as well, so I'm not surprised that the bearings were pitted.

Those (Shell Alvania EP2 Grease and Texaco MultiFax-EP2) are Extreme Pressure #2 greases, as the names say (EP2). And from a web search it appears Shell Gadus S2 V220 is available in a grade 2 as well.
