Do you recall the size of the u-cup I.D.? I was hoping to see the specifications of the u-cup you used.

Widetrackman

Yes, the lenght of the top part edge retaining the u-cup is excessive. As little as 1mm should retain it, maybe 1.5mm if you are not sure it will retain the cup.

i looked at the info i saved and can't help you past that. all i've got left are some photos in a gallery somewhere. if you want, i'll try to find them again. got something going on and the photo downloads are kind of going to whichever photo file they like that day.

A little slow getting back as have been in a trial all week. Thanks to all for the great info and help guiding me in rebuild of my jack. Thanks again.

Wrote the blackhawk guys as Hiball suggested and they have rebuild kits for the aff
2100. If you are still needing pieces/parts. Not sure what is in the kit, you will have to check.

Well purchased a kit for the Intermarket from Blackhawk and was not impressed. It did not have the packing for the release valve, no oring that fitted for the ram (too loose) dug one up from my stock) for the nut as well as the large oring CS was too large for the oring gruve as well as the reservoir bottom I crushed them in when tighting the nut . We will see what happens. Also charged about $16 to ground ship a 3-4 oz $35 kit from Chattanooga, Tn. to Oxford, Ms. could have shipped by priority mail for a third of the cost. Give me a break!!. Best thing is find a local hyd. shop and buy single parts, I was lazy so paid the piper, but not again.

The u cup for the pump piston is 12mm x22.8 as. per my kit. Also had to cut the top part down. Could not get it on even with my boiling water trick. Again thanks to all for the great help. I'll post later how it worked.

Unfortunately that has been my experience from other members when dealing with blackhawkparts, they up charge something fierce on shipping.

Assuming you mean 12x22x8 And yes.. Everyone of those jacks I've worked on has met the grinding wheel, which is why I quickly made that recommendation to Bill (little ponderosa) when chatting via PM and joked about the abnoxious button size. Did you contact Blackhawk about the missing parts?

You are correct I typed it wrong. When I ordered I asked if everything was included and was told the dust cover was the only missing componet. I called after receiving the kit and was told the release valve packing was unavailable. They were nice and advised I could return the kit. At $16 shipping already and return shipping I might as well just keep it. This does not seem to be a good kit fo this jack (as per my previous comments) at $51.

Well that *****.. If you run into any problems with the release not sealing, give me a shout via PM, I might have some seals that will work.

Thanks Hiball, I used a piece of vacumn tubing, feels a little funky ,we will see. May give you a shout if it leaks. Thanks.

BTW, I would advise members rebuilding Jacks or other Hydraulics to stay away from Blackhawk due to gouging on shipping and kit integurity. Dont get lazy like I did, shop around for indivudial parts.

 

[littleponderosa]

Damn, they are not getting my business. What is the deal with shipping and why not the correct parts?
I'm hoping I can find replacement parts when/if this jack goes out again. Local hydraulic shop - 100 miles out - wouldn't even return emails or phone calls. So, I'll be bugging Hiball for more assistance or Edgar.
What is the chance the replacement o-rings I purchased from the larger hardware store -45 miles the other way - will hold. Not gonna hold my breath yet.
Thanks again for all the info gents.
Bill

 

[widetrackman]

BTW I forgot to mention Blackhawk is AKA; Tools and Hydraulics Inc, Chattanoota, Tn. Stay away from both if you can. Even the rubber fill plug would not fit.

AARRGGHH - ok, now I'm disgusted. Got off night shift this morning and after a short nap went to the garage for some me time. Pulling apart the JD 140H3 - another story - and decided to move some equipment around for some laydown room.
Under this newly rebuilt jack is basically the entire oil capacity of the jack - maybe using 14 year old rebuild parts kit wasn't the best idea - but I had it and be damned if I wasn't going to use it.
Light weight stress test on the atv, only picked up a couple front and rear tires off a Chevy 4x4 so it isn't like I went over the limit.
Question: rebuild it again with fresh seals and rings or put it in the scrap pile? I'm undecided and since I'm pissed my judgement is suspect.
Appreciate any opinions you fellas may have.
If I need to, I'll buy a new jack - preferably one made in America.

Hiball - have any non-payment decent jacks in the shop you would be willing to part with that you have some cashola in and can't get rid off?

Maybe it's just a leaky reservoir? Possible that you cut a Oring on either end? Did you install them dry? It's very easy to damage a reservoir oring upon installation if at Min you don't give them some hydraulic oil to aid in pulling inside the tank. I would definitely try and figure out where the leakage is coming from.

 

[littleponderosa]

Started disassembly already. I should get it torn down and apart by tomorrow unless I go goose hunting - or do something constructive and go X-Mas shopping for a gift for the woman. Probably should go shopping. Probably won't.
I'm at a loss at this point - soaked everything and saw nothing on assembly that could have gone wrong. Evidently I was incorrect.
Hoping I won't have to bug you for parts/pieces but I'm not holding my breath. If I do go shopping I am going to town, I'll see if the local hydraulic guy has any seals/o-rings.

Well, blew up the jack and I decided to try to find a kit. Called the original source I had used in the late 90's, and I got lucky. Tri City Hydraulic Jack Service in Tampa, FL had one sitting on the shelf. Great folk. Husband/wife operation that has been in business since 1965 and is shutting down for retirement at the end of the year.
I'd recommend anyone looking for the non-stocked parts/pieces to give them a call. I'd do business with them again.
Now, looking forward to rebuilding the jack thi s time with fresh parts instead of the parts that sat in the garage for over a decade and evidently dried up.

I hate to revive a thread from the dead for my first post but I just finished rebuilding the same jack and I thought the o-ring sizes may be helpful as it's doubtful that a kit is available. I didn't replace the stem seals or the small ucup on the pump. the other o-rings sizes are 1-2mm x 70mm, 1-2.5mm x 84mm, 1-3.5mm x 31mm, 1- 2.5mm x 52mm, 1-2.5mm x 17.5mm and 1-40mm x 50mm x 8mm cup seal. The 17.5 mm o-ring could probably use an 18mm. It was too close to call. Thank you for the members that contributed their knowledge and making my rebuild a success.
