    CAT 301.8 stick comes slowly in on its own

    Ok, found the problem. All the seals have now been done. I'll put it back on tomorrow. Should work a fair bit better now. New seal kit from CAT had a blue seal where that orange one has failed. I'm thinking that one was not genuine.

    CAT 301.8 stick comes slowly in on its own

    Ok fellas thanks for the input. Turns out a neighbour of mine is very handy. He lent me some plugs and I have now isolated the valves in question and the stick still comes in, thus it is the seals in the cylinder. They have just now been ordered from CAT and I will set about dismantling and...

    CAT 301.8 stick comes slowly in on its own

    Thanks Vetech. The way I read it, 23 and 24 are attached to the Boom valve(2). My problem is related to the Stick valve(7). This has item 20 attached either side, labelled as "Valve AS".

    CAT 301.8 stick comes slowly in on its own

    Ok. I get it. I don't want to do work for no reason either. The arm (stick) does not travel outwards on its own. I'm not sure I have a valve. Here's the pages from my parts book. It's not shown there. If there is a valve, where would it be located? I could show the relevant page/schematic from...

    CAT 301.8 stick comes slowly in on its own

    At the moment if I push out on the stick, then stop, the stick will gradually come in on its own accord. If I pull in on the stick and stop, the stick continues to come in on its own, it does not travel on its own outwards.

    CAT 301.8 stick comes slowly in on its own

    Don't quite get what you mean. You can see in the video, with engine off, it falls rapidly to a point where it wont go up hill, or in any further as that would be against gravity. It does not slowly go "out".

    CAT 301.8 stick comes slowly in on its own

    The squeal, hiss is definitely from the clyinder. It's coming in more quickly all the time now.

    CAT 301.8 stick comes slowly in on its own

    Thanks uffex. I might have to check their (exatech) library a bit more. And get some plugs. Assuming it is the seals, is this something the average (bush mechanic) can do or best to take it of and let someone else fix it?

    CAT 301.8 stick comes slowly in on its own

    I've had this problem for about a month now. While walking or working the machine in any way without pushing the stick outwards, it will slowly come inwards on its own. Not strong enough to go against gravity but close to it. There is obviously either some sort of bleed off, or into it, to make...

    Caterpillar 320c overheating

    Read a few other threads. I always run the machine with the hood up - thinking this gives more ability to cool. I have run it with the hood down and it overheats quicker. Now I am wondering about these bits of foam that might direct air flow. Also wondering about relief valves in the oil...

    Caterpillar 320c overheating

    What was "the wiring problem" you mentioned? I have a CAT 301.8 mini-ex that overheats. I have done similar things to you to diagnose it. I will get some temperature readings of top and bottom hose as well. I have cleaned out my radiator several times. I have also removed the oil cooler...
