Jerry M
Very Pleased 7/16/2017

Purchased the Grizzly Model T27978 50 ton shop press shipped to my door. UPS shipping document said the wood crate weighted 574 pounds and it was my job to get it out of the truck.

On uncrating it I was pleasantly surprised to see it already 90% assembled. The winch cable was installed and all the high pressure hoses connected! All I had to do was bolt the winch and jack to the sides and then assemble the base.

OOPs!!! What is this? A coiled clear hose coming out of the rear bottom of 50 ton ram? Parts List showed it as item 47 and called it an “overflow hose”. Where does the other end attach? The Manual gave no clue.
Called Grizzly Tech. and ask them about it. The Tech. was super nice. But, I felt like I caught him in my headlights. He knew exactly what the problem was but the answer was nowhere in his data bank. Even went and looked at the one on their display floor. There was the mystery hose sure enough, still coiled up on the ram and attached to nothing. He laughed and said do what we did just leave it there.
MY research & thinking theorizes that the hose captures oil leakage from the ram piston seal and drains it back to the pump reservoir. I removed the vent petcock on top of the pump reservoir, uncoiled the mystery hose and it screwed right in. See pictures.

I must say, I like the new press. The cross beams and table are made of 7” Channel w/2.75” Flange x5/16”Thick. The columns are 3 7/8”W x 3/8”T Flat Stock. The table support pins are 1 3/16” Dia. The table plates are 1 ½â€Tx2 ¾â€Wx12”L steel. It seems quite strong to be the cheapest 50 Ton I could find and I have allways enjoyed dealing with Grizzly.

Good job GRIZZLY!

PS: If pictures attach ok, the last one is a soda can being pressed with 20 tons.
