Can this cylinder be repaired ?

[FBG3]

I have 35T Husky(Speeco) splitter with a blown rod seal. I am sure the cylunder is Chinese but I would like to reseal it if I can get the gland/head out.
I dont see any holes for a spanner or a retianing ring. There is a socket head screw and washer in the gland that looks like it would be for bleeding air but may be a lever point for unscrewing ? Here are some pics with and without the cap screw. Any suggestions so I dont have to buy a new $400 cylinder are appreciated.

I believe you remove that bolt and then push that rod gland assembly back into the cylinder a ways to expose the retaining ring.

That socket head bolt may be a way of grabbing the gland to unscrew it, as you suspect. Also look for a small slot in the side of the outside of the cylinder barrel, a half inch or so from the top to see if there is a wire lock.

Once off, it is easy to find the wiper and gland seal by size. I recommend the special tool to install them.

Another possibility. You may be right, O&S.

That is the way it appears to me also.

Yes, that is how it is built.....see video:

If I was having difficulty getting the rod out I'd fire up the pump and use the hydraulics.
You loose a little oil but it comes out easy and gently as I've had to do it a few times to get the rod out on backhoe cylinders. Never use air pressure you'll be launching a rocket.

I have used air before, but I am very careful, doing it outside, and giving the rod a clear path, and covered with a tarp.

I worked on one of those Chinese logspitter cylinders years ago, and it was also a 5-incher, the biggest cylinder I have ever taken apart. The gland was retained a different way, however. The factory had scuffed the big O-ring in original assembly, so I did not have to replace the gland seal. It was difficult getting the rod out, that is for sure. I would hate to have to resort to using hydraulic fluid.

In the video above, the guy did not buy the special tool to get his gland seal in, and he really struggled. It is even harder for seals on smaller cylinders.

Thanks I' ll give that a try and get back to ya'll

Thanks ruffdog. I had seen the video but it wasn't clear (to me) how he got the retaining ring out.

Ok I got it apart. I removed the screw and tapped the gland into the cylinder with a block of and hammer and pryed the retaining ring out.
I then started the splitter up and used the hydraulics to push the gland out as far as it would go.
I had to use a come along and big soft blow hammer againts the pin I had in the rod to get it fully extracted.
Now I need a good source to identify and buy a kit for the seals & O-rings

 

[ruffdog]

There are a bunch of kits online.....what is the bore size and rod size?
My old Speeco manual shows these numbers for seal kits:
HC390120F for the 4" x 24 cyl
HC390171 for the 4.5" x 24 cyl
HC390126 for the 5" x 24 cyl

Thanks ruffdog ! I orderd the 5" kit from Amazon and got the seal installers set too.

Back in action !
Thanks to all

Correct. The only reason I am going to read beyond this point is to see what others think should be done. I have rebuilt tons of this type of cylinder

Did you forget to set your alarm? You're about 10 days too late.

Yeah, I get those too if I haven't been back to the Forum in a few days. They're always for old threads. I think they're just making sure we're still above ground.

Being on the sunny side of the grass is always a plus. I usually get an update from the forum about once a week , and I read thru it . When I see an interesting post I sometimes post. I spent many years on the road as a mechanic for commercial and industrial equipment and some of the responses to some of the questions can be very entertaining.
