Hey just a thought.... is there a grease fitting on the clevis? We had a frozen 8" pin on our krupp stacker/reclaimer. We loaded up a grease gun with Kroil and pumped it into the grease fitting after heating the crap out of it. It loosened the joint and allowed it to accept grease. We couldn't take the pin out as it was supporting about 100 tons of structure so this was a last ditch effort.

Thanks Norm. You are a wealth of good information. I have no doubts that you would already have this pin out, cylinders rebuilt and the hoe moving some dirt.

The clevis doesn't have any zerk fittings at the pin. I was thinking about drilling, tapping and installing some. That would be a wise move for added serviceability in the future.

Speaking of the future, the stabilizer rods are pretty worn. Pitted, peeling and grooved. New ones around $400/ea before shipping. I have heard of people buying chrome shafts cut to length. Then having the old eyelet cut off and welded to the new shaft, then having threads machined in for the piston bolt. People are claiming $150/for for this. I am not sure where people are buying the chrome shafts or who they send them to for the machine work.

I have heard of others of grinding out all the peeling chrome, burned out contaminates and using jb weld, super glue or similar to fill the imperfections. Afterwords sanding it smooth and running them. These are suggestions, but I have not heard of people claiming fails or successes after trying this fix. I am tempted to try. Seals kits are cheap.

Bugets are made to be blown, and this hoe is has been a money pit. The farther I dig the more issues I will find, which will require more time and money. I am one for doing the job once by doing it right, but saving coin sounds really nice. The hoe is just going to be used for farting around at my property.

Well I slept in today, so I didn't have a chance to get bottles. I did rebuild a different cylinder. One down, 11 more to go. Kicked my bum. I am getting too old for this and it is getting way too hot.

I have used an epoxy called devcon to fix the seal area on a centrificical pump. It works pretty good,  but you have to machine it after applying it on the shaft. If not it will wipe out the seal in a few minutes.

Was able to cut it . Did this a few weeks back. It took quite a bit of heat. Now I need to get the pin end out of the clevis. Unfortunately the backhoe did not catch on fire, so have to continue to work on it


After all that, it would cost too much to fix the shafts. Ordered 2 new shafts and 2 new caps. New front main seal, rebuilt the injectors pump and hydraulic pump. New water pump and alternator.

Going to try and drill the rest of the pins out this weekend

Thanks Norm for the assist!
