This guy made me laugh sooo hard!!! I love it! He gave me so many ideas of what NOT to do, and I think my repair will go much smoother now. Thanks for the video. I may post one of my own.
You can’t learn if you aren’t willing to fail. I learned what not to do as well. Plus you can’t hurt my feelings, I used to hold the flashlight for my Dad.
@@graybeardgarage9638 I understand these jacks were made in Japan and are top quality. You will not find a kit for these, and everything that says it will work is wrong. The seals have to be purchased individually. I have replaced the rod U-cup seal and the pump piston O-ring so far and now know I have to replace everything. So I have to dimension them and do parts look-up. The U-cup seal is: 9514K151 High-Stability O-Ring-Loaded U-Cup Seal for 0.275" Groove Width, 1.375" ID x 1.625" OD x 0.25" Wide from McMaster-Carr. This is a special U-cup with an O-ring in the U to maintain pressure in critical operations, sch as a jack holding up weight that could squash you. I will give you dimensions on other things if you like also as I go thru mine. I started out just thinking it would be a small job, and found out otherwise, The U-cup rod seal was bad and the only thing I had to go on was a tiny disintegrated piece of it nad (luckily) the loading O-ring which let me know it was a special seal instead of a common seal. I did do stuff like this for a living and I have a degree for it, so don't give up! I am making a lot of mistakes as I work on this too, but for $16 vs over $150 I can live with it.
Pretty sure its a Sears 9-50115 3ton. All o-rings are metric. Plunger o-ring is a 3.5x15x22.(9263K771) I think mine was missing the backup for the o-ring from the factory. The plunger "wiper seal" is hard to identify. 15mm x 22mm ( can find 15x24 units ) As for the cylinder seal, they say there are two versions. A 42mm(v1) and a 40mm(v2), I have not gotten to that point yet, as I have received a kit from supply house that listed their kit for the 9-50115 jack.....WRONG in every part except the cyclinder oil fill plug.(go figure) The wife shook her head, returned home with a 4 ton jack. 😊
