seal search

[ohiofarmer 3,276]

 i was after mower decks and the seller pretty much threw in a roller tractor for free. I managed to make a seal puller that got the seals out with the axles still installed, but the numbers on the seals are not quite readable. they might be 88  105018  [if that makes any sense]

The axle shafts are exactly one inch and not rusted at all. It was difficult to get a reading on the outside bearing tins as they were a bit distorted. My best judgement is right at 1.500 inches. thickness is .325..The transmission is a Sunstrand 90-2019 mounted on a 1075 tractor.

  Hopefully, there is a reasonably priced axle seal for this, and I might need a seal on the input shaft once i am able to get it loose. The fan, if it ever had one is just a little torn bit of aluminum held on with 4 small screws. I did manage to power this transmission with an electric motor and it does seem to work. there is no visible push valve on the top like my other one and no slotted screw either.

 

 Thank you in advance for your advice

Going out on a limb here but I think the pump input seal should be the same as the ones used later on on the hydrogear and piston to piston sundstrands.  CR7474 (single lip) or CR7475 double lip (my preference)

Outstanding help just amazing. I had previously searched on post 2 and it did not seem the OD was big enough. Anyway, with the picture of my exact transmission,and the seal dimensions the confidence factor is huge. Now i also know which bolt is the tow valve.

 

 Now all i need to do is check and see how many of my transmissions are 1x i.5 bore and order enough seals for all of them.
