    Frame break Komatsu PC 110R

    He got a little further in the repair over the weekend. I cut out and ground out the broken welds and tried to pull the frame of the machine back to its original position. Unfortunately, it won't be as simple as I thought.:( I lifted almost the entire machine with a 50 Ton Hydraulic Jack, but...

    Frame break Komatsu PC 110R

    The structure is cut out of board material, not fiber material. Special material, the material of the cut welding root sounds like the blade of a sword! :)

    Frame break Komatsu PC 110R

    Unfortunately, I don't know the history of the machine. The machine is in very good condition, the included spoon does not show any damage.

    Frame break Komatsu PC 110R

    I don't think the entire frame is preheated before welding during series production. It was produced in northern Italy and it is possible that the production took place in the colder winter period when the raw material was colder and the welding cooled down faster?!

    Frame break Komatsu PC 110R

    Fortunately, there is no box, by removing the cab you can easily access it from all sides. I also thought a lot about what could have caused this break?! The machine is 15 years old and has 8,100 working hours and is in very good condition. It was owned and operated by the same person...

    Frame break Komatsu PC 110R

    Thank you for your advice regarding the preparations, (dismantling, grinding, preheating, slow cooling...) this is fine. I have a personal relationship with a welding shop, where they help me choose the right welding rod. For me, what is still not clear is the stress relief after welding, could...

    Frame break Komatsu PC 110R

    Hello Dawe, ok. Unfortunately, I do not speak English and I use the Google translator for communication, which does not always give a clear translation. That is why I may ask you several times about the same topic, so I ask for your understanding and patience. Thanks.

    Frame break Komatsu PC 110R

    Hello Lagwagon, Hello Dave, Thanks for the info and advice. I appreciate! Yes, I have experience in this field and can also weld. I also have tools.

    Frame break Komatsu PC 110R

    Hey guys! I would like to ask for help with a Komatsu PC 110 R frame break. I've heard that this is a common fault with these machines, but I couldn't find any information about it online. Has anyone had a similar problem or experience with this? I'll try to take photos of it tomorrow. The "Y"...

    943 B It loses performance when warm.

    In the meantime, the aforementioned seals and connecting rod bushings from Caterpillar arrived. I have already installed the rubber seals and O-Rings in the hydrostat. The inside of the hydrostat was "pharmacy" clean :) There was no sediment in the oil pan, I found few, very fine metal particles...

    943 B It loses performance when warm.

    Greetings to everyone. I am sending here some pictures of the inside of the tank, of the filter. All parts are intact and original, only minimal rust is visible in the tank. Because of the suction head found in it, I concluded it was a foreign substance.

    943 B It loses performance when warm.

    The filter and tank interior are in good condition for their age! I'm guessing some foreign material, because I found a metal ball suction head in the tank earlier, which may have fallen in at some point when they wanted to suck the diesel out of it.

    943 B It loses performance when warm.

    Hey guys! I found the following problem in the diesel fuel tank. (However, the inside of the tank was nice and clean!) Look at the photos... The suction pipe elbow was almost completely blocked with some old pieces of rubber or plastic! The engine could not get enough fuel under load, which...
