Where to buy quality cyl seal kits online?

I have acquired a neglected Case 580E backhoe and am going thru and fixing leaks. For front loader cylinder, i purchased two cylinder seal kits:

$19 from eBay, all no-name seals, fit and finish seemed lower than the below kit.

$32 from foxkit, included at least one SKF marked seals. Quality of fit seems more precise than the above.

My questions:
- does the use of name-brand seals make a difference ?

-where do you shop for quality seal kits?

Thanks !

Hercules.

Welcome to HEF, Birdseye !

Thanks for the sources.

The kit is p/n G109423.
Hercules is $60

Baum Hydraulics is $32

None of the sellers list any specifics on the source or brand name of the seals, probably I’ll have to call them. The prices are all over the map.

Global economy. So like most everything even dealer supplied seal kits that says case on them and cost 70.00 all come from China. Most likely right off the same line. Like everything else one goes left and goes in Xyz back one goes right and gets bagged abc. I don’t think quality would be an issue if that’s what your concerned about. No matter where you go odds are good your getting the same thing.

I've used a whole bunch from Baum with good results, the 2 or 3 minor problems I've had were handled promptly and pleasantly. That's why I recommend them.

I recently bought some seals for my MF30E industrial loader. I was unable to find the seal kit through a Massey Ferguson dealer. Ok I did find them, but the whole kit was $170 for one cylinder.

I disassembled the cylinder and measured the grooves on the piston. Using the measurements I purchased new piston seals from MFP Seals out of Michigan. I believe it stands for Martin Fluid Power.

Two days later I received the seals and had the tractor back in operation. I was rather pleased with the experience using MFP Seals. It was a unique seal because it was metric 65mm bore. Easy online ordering, quick delivery, and good inventory. I think I will use this wholesaler for my next seal purchase. I also picked up some seal kits for my Bobcat tilt cylinder. I forgot to mention the piston seals were $7 per piece.

My supplier has several source suppliers, Hercules is one of the more prevalent.

I have ordered several times from CEA_Services in Florida. I have always had good luck with them. The kits are all Hercules. Every kit I have gotten has SKF-USA seals. If you order, it is best to call. They tell me that Corona has made the kits hard to get. I am currently waiting for 4 kits from them. They say they cannot get them from Hercules themselves (also in Florida). CEA_Services also sells on E-Bay, but they charge more on E-Bay. They have a good rating on E-Bay too, but I had a member on here tell me he had a bad experience...I have not.

As an example: I just purchased a new gland and seal kit from Messick's. The seal kit from them was $154.53. CEA_Services has it for $53.23 plus like $5.00 for shipping. Normally I would have just gotten it from CEA_Services but it was having a problem and the dealer was helping me thru it so I purchased from them. Big difference in price, but the Hercules are at least as good as OEM New Holland.

Having never come close to attempting to reseal cylinders I just searched for New Holland lb57b cylinder seals and came up with:

I assume this is good enough but are seals going to differ from model year to model year?

There's also this for a know-nothing like me...:

Anyone have good or bad experience with HW Partstore?

Sorry to take over the thread with a million questions... Does anyone have a list of the tools needed to replace these seals? Should I, as a complete novice but not afraid to get dirty, try? I remember a post with a video showing seal replacement on a different thread and it looked manageable but I'd hate to cripple my machine with incompetence.

I'm assuming one of each of these may be wise?

aighead;
Look at your cylinder glands to determine if you need a spanner or pin style wrench.
If they are pin style be sure to get the large size adjustable wrench.
Ebay prolly has the cheapest.

I've recently ordered 4 kits from HW parts for my 310 SE. Supper easy to use website. Shipped next day and the seals appear high quality. I could tell the origins of some of the seals, USA, Corteco and Wonyong - Korean supplier for Doosan and Hyundai.

I should probably buy a spanner for my end cap. I've been using an air chisel. In some cases I'd still have to use the air chisel to break it loose though.

Aighead,
As far as seal kits go, I see that there is a serial number break so you need to look up the correct unit. What I do is look up the correct part on messick's or New Holland's site, then use that part number to order a kit from an aftermarket source...usually CEA_Services for me.

As far as tools, it depends what cylinder. Which cylinder or cylinders are you looking to rebuild?

As far as attempting the job, this is how I look at it...If I cannot do it, I can take the rod assembly to the hydraulic shop, and they can do the seals and then you can reinstall the rod assembly.

I have a writeup on a stabilizer cylinder somewhere on here. I will look for it and post if I find it.

EDIT: Here is the link

My first two leakers I had a guy rebuild them.
I did my first cylinder rebuild and used https://herculesus.com/ I think they were about $29 per loader cylinder dump kit.
They also sell a their own seal twisters which was real handy.

Also be careful when making a seal kit purchase that it is the complete kit.
Piston seals can be purchased without the gland seals from some vendors.
Those u-cup installation tools are a must have item. They are available in three different sizes.
They are also sold in a set of three.

I replace a piston seal on my MF30E tilt cylinders in this video.....I did not replace the rod seals, but you have to weasel them in the gland without damaging them. The trick is forming them into a 'kidney' shape. I saw special tools for this, but have never tried one.

I too am a novice learning as I go to. Previously I have only repaired a few smaller cylinders.

In regards to the recommendation of Baumhydraulics by Mitch504, I went on their website and was impressed by:
- searchable with OEM part numbers
- good prices (middle of pack)
- specific information on each part included in the various seal kits

So then I called and asked the sales person about the source of the seals and he assured me that they come from their suppliers some of whom are US companies. Feeling comfortable with what I heard, I’m going to order four kits and see how it goes. Hopefully some of the seals will have major name brands like SKF, Timken etc.

You guys, as usual, rock! Thanks for all the input.

Am I correct to think that the "seal twister" and the "u-cup installation tool" all go to form the "Kidney shape" and are basically the same thing that helps get the seals in properly?

@Swetz I assume, eventually I'll reseal them all. Right now I think I should be focused on probably the boom and the left stabilizer as I think I've seen it spray a bit... I haven't dove into your replacement post yet, but at first glance it looks incredible.

Thanks again, guys!

Everybody seems to buy the 3-piece u-cup tool. This is the one I purchased. One of the reasons I chose this one is that it is in the USA. Some e-bay sellers are in China and take forever for you to get your order. Look at the pictures in the listing and you will see how the tool works. It really makes the seal install a nonissue.

https://www.ebay.com/itm/3pc-Hydrau...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

I think I would start with the stabilizer cylinder, then work on the boom...The boom is a bit tricky and much heavier (cylinder is heavy and it is up higher). Be aware of potential damage to the rod. The stabilizer rod is down near the ground and is often damaged, so inspect it. It will only cut up the new seals if not repaired.

If you read through that thread I linked you will see the tools that I used. Remember, you do not have to remove the entire cylinder to repack. You will need to remove the rod end pin and the gland nut.

Another caution is do not use air to run the rod out...If you loosen the blind side hose, you can just pull out the rod assy...be ready for the flood of oil on both sides of the piston. Yes, in addition to the parts and tools, I recommend purchasing a 5 gallon container of hydraulic oil.

If you have questions, just ask!
