GarWood Hoist Questions

[Curt Hanson]

Went to an auction Sunday and bought a 1963 Chevy C60 with a grain box that "wouldn't lift" for $375. Found it is a GarWood pump and had a input shaft seal popped out of the pump housing. I took it off, and after inspecting and unsuccessfully searching the web for a replacement, I put it back together and hoped for the best. Well I had it working tonight but after topping off the oil I lowered the bad and the seal came out again. My main question is how do I make sure the oil level is correct in this system? It has no reservoir and the only way to fill it is by removing a plug in the top of the cylinder. I assumed you raised the bed and just filled the cylinder until it wouldn't hold anymore. Now I'm wondering if I put too much in and caused the seal to come out. I haven't had much luck finding info on this type of system and any info would be appreciated!

look for a vent in the system seems like it is trying to vent and pushing out the seal.the plug where you fill it should have a hole in it.fill the system with the body up and when it comes down it will push out the excess

Thanks Russ,
An old boy that is pretty familiar with this type of system kinda said the same thing. He said in the past he just drilled a 3/16" hole through the pipe plug and put a cotter pin in it. I was going to try that, them I saw a vented 3/8" pipe plug on ebay for 5 bucks so I splurged and ordered it today. I wonder if it had something like this originally? Thanks for the suggestion.
