Thanks for posting this video which helped immensely with the same issue I had with the 27 ton model. I did not remove the cylinder. I propped it up, turned the control valve 90 degrees to allow the spanner wrench (you posted) free 360 degree travel. As with you, I ground the spanner wrench nub to fit. The end cap of course was not coming off easy, so I lightly heated the hydraulic tube casing. After hammering the spanner wrench a more few times the cap began to move. The rear shaft plunger assemble was completely at the rear of the hydraulic tube. I was unable to pull it out until I discovered the nut was still in the recessed portion of the plunger assembly at which point I was able to screw the ram onto the nut slightly, then retrieve the nut and plunger assembly. I used a generous amount of Loctite 272 on the nut. One must first put the end cap assembly on, then the rear plunger assembly due to the type of seal used on the inner endcap. Everything went back together and works perfectly. Thanks again for the video.
I was thinking about this a bit more. Before taking anything apart, one should extend the ram against a log in hopes of pushing the piston to the end of the cylinder. Do not reverse the ram.
Mine was completely extended and was in no way retracting. I will say there was an indication that the nut was becoming loose. When the ram retracted it bounce back out slightly, then increasingly so. When the nut completely came off, the nut remained in the recessed end of the plunger assembly firmly against the end of the hydraulic tube. Thus I was lucky and was able to screw the ram partially onto the plunger assembly and then able to pull it all out together, retighten the nut and reassemble. @@zzzingrol
Thank you very much to the person who submitted this video!! The nut on my 27 ton Champion had also fallen off. Thanks also for the tool tip = speed spanner. With some modification the tool worked perfectly.
@michaelharrington8231 Hmm, some people suggest try leaving the cylinder in the frame if possible. Also try using a hammer to hit the wrench. Make sure you are rotating counter clockwise when looking from the cylinder end.
Is it left handed threads. I'm assuming no. But either the factory put lock tight on the cap of the threads are buggered. I have used a Hamer a 5 foot bar on the c spanner. I can't believe what a tough tool it is. Lol
