seal for post hole digger

[cedar21]

I was able to get a seal today that seems to be working. The inside diameter was slightly smaller than the old seal, but I was able to get things back together.

One more question though. The post hole digger has a filler hole on top of the gear housing, though there is no hole to check the oil level. How full should the gearbox be filled with oil?

I stock a replacement seal 1-3/4" OD, 1-1/4" id, AND 1/4" thick, CR# 12364, they are $4.32 plus shipping which would be about $3.00. Looks like I have 20 in stock.

I may order one of your seals to have a spare on hand. Thank you.

75 per cent of pumkin houseing full , so you do fill it up complete and create unnesary pressure and blow gasket etc . Its also good to see from one of your pics your pto shaft cover protector looks in great shape . They should have a little chain on them to keep cover from spinning .

Post hole digger seals take a beating. Use Corn Head grease from John Deere or look for polyurea EP #0 grease.

I have had good luck with Cornhead grease on gearboxes. I have said before, they should come that way from the factory.

I used GL 1 90 Gear Oil 80W90 in the gearbox. So far the new seal seems to be working.
