 Posted: Tue Aug 28, 2007 7:48 pm Post subject: Hydraulic Jack Rebuilding? |
 |
|
Does anyone know anything about rebuilding hydraulic jacks? I have 3 of them that need to be rebuilt or new seal kits put in them, and I was told not to throw them away that they can be rebuilt.
I googled for a few minutes looking for an outfit in Chicago that does this type of work, but came up empty-handed.
Does anyone have any experience with this or info to point me to?
Thanks!

If you are going to take it to someone else to rebuild, then you are better off throwing it into the scrap metal pile and buying a new one, as they are so cheap these days. I ran into this issue a few years ago, and the hydraulic repair shop told me it would cost me more to pay them to repair the jack than to buy a new one.

x2. The last place you want to skimp on is the thing that's holding up the car while you are under it. I know people use jack stands too but this is definately not an area to be cheap. On the upside, you can get a decent amount of coin for the jack as scrap because they weigh so friggin much.

Lincoln (snap on) jack rebuild $50 or less New was $350 (many years ago).
Had a ram that I went to get new seals and they were installed for free and the seals were cheap. |

For $29.99 you can get a 12 ton jack from harbor freight. But I myself don`t like buying anything thats made in China. I bought a 4" grinder for $10.00 at a flee market once and it lasted 8 sec. and burnt the shit out of my hand. Anyway you get what you pay for. PS. 6 and 7 year old kids shouldn`t be working in a foundry just to make American CEO richer then they allready are. Just my two cents.

I got an ad from Harbor Freight today that 3-ton jack stands are on sale for $11/pair this week.
I would be scared to use those. |
I use the 6 ton ones when working under my car. I wouldn't even want to try the smaller ones.

2 of them are Big Red floorjacks - 1 1/2 and 3 1/2 ton - if that helps any.

My old craftsman needs rebuilding. I looked up the price for parts and for the MANUAL they want $13. |

Take the jacks apart and take the shaft and old seal into a hydraulic shop. If it's a slow day they might match up seals to fit.
Before you disassemble the jacks try this. Open the valve that lowers the jack and then pump the jack handle a dozen or so times. Now close the valve and see if it pumps up. Many times we get jacks back that have been laying on their, side allowing air to get into the pump and airlocking the system. Opening the valve and pumping out the air will sometimes get them working again. This is frequently the case where the jack has been leaking out of the fill hole and is low on fluid. |

I also had a Sears Craftsman flor jack that I bought on sale maybe about 1980 for $149 (regular price $179). When it died a few years ago, I also found it would be too expensive to fix, and parts hard to find (two trips to repair shop, etc.). The chain stores (CSK, Autozone, Pep, even Sears 5pm this Friday to noon Saturday) routinely sell floor jacks for $59 or less. Just make sure to get one where the difference in lift is at least about 16 inches, and these jacks weigh about 90 pounds, if you're thinking of using it to remove your engine or transmission; the $29 jacks are significantly smaller. Unfortunately, that's about all that's out there; I'm not saying these $59 jacks are equal to my old Made in USA jack, but that's what's there.

Very true. I had a cheaper Sears one but stopped trusting it when it started weeping oil. Had it for over 20 years so got my money out of it.
I replaced it with the larger Sears floor jack (about $140 on sale). It it a heavy sucker but works great.
Their heavy duty jackstands are pretty decent also. |

Harbor Freight made everyone honest with the quick pump aluminum racing jacks (zero to full height in something like 3 pumps). Last I saw, those jacks are typically between $89 and $99 depending on who is running a sale. Not bad for something that came on the market about 8 years ago at $399.

Same here. When my 20 year old jack crapped out, I spent a day trying to rebuild it. Ended up in the trash bin and had to get a 2.5 ton heavy as all hell one. Had to buy what was there as I was in the middle of a big job. Later, I got one of them "pit crew" quick pump quick down aluminum 40 pounder which is bitching at quick jobs as well as light enough to take on long camping trips and such!
