    blue locktite failure

    John, if brakeclean is left to evaporate in a puddle on it's own, it leaves behind whatever residue it has thinned/broken down, I agree with you. However, by using compressed air it leaves "virtually" nothing behind. The fact is, locktite isn't as fussy about this sort of thing as say aluminum...

    blue locktite failure

    A point of note on this one, in order for Locktite----- any Locktite, to work as intended according to its strength, the parts you're placing it on must be clean. If there is any oil or contamination, you can nearly treat whatever color you used as a step down to the next weakest color. In...

    410c hydraulic help

    Well, I managed to get a couple of hours fiddling with the machine today. I began by hooking up my pressure guage and running it into the cab so I could observe it. Pressure at idle @2700-2800psi. I then began to time the movement of the booms. RPM was set at 2000 Front main boom up 3.5 sec...

    410c hydraulic help

    Geeze, I didn't keep the piece, poured it out with the oil. I'm curious what you mean about not touching the return line. Is it hot? I'll have some time this afternoon to hopefully hook up my gauge to the pump and view some live pressures. I'll crawl under the machine and see about how though it...

    410c hydraulic help

    Thanks Willie, those are interesting thoughts, and a good explanation of the priority valve. I'll have to see if I can source the proper sized plugs for the valve. I pressure washed and degreased pretty much everything I could reach quite thouroghly so I could see what's going on under the...

    410c hydraulic help

    Thanks Delmer, I'll give that a try. The functions of the booms and bucket move quickly without load. I believe I have a spec sheet for the stroke/movement times but haven't bothered to time them as they very responsive but I will, along with keeping the test guage on the pump. Luckily I had...

    410c hydraulic help

    Thanks again gentlemen, I had a chance to do some of the service on the machine today ie. change out hydraulic fluid again and engine oil/fuel filter. I also had to change a leaking pressure line, and suction line to the pump. By the time I was finished I didn't have enough time to recheck...

    410c hydraulic help

    Thanks Delmer for your response, yes I do have the 2700psi, however, am unable to dig with the machine. That's the part that really doesn't make any sense to me, you'd figure that if the pressure is there, that it would work perfectly. It simply doesn't have the power to dig as it should. I...

    410c hydraulic help

    Thanks Willie, what you say makes sense, truthfully, I'm trying to grasp how this system really works. The bumping of the front controls really has me scratching my head. It's only for a second, but it definately provides some sort of bump to the back end. It's as if it forces the pump to move...

    410c hydraulic help

    I should correct something, when I said I "bump on the bucket control functions" I should have said, the front end bucket and boom on the front of the machine.....sorry.

    410c hydraulic help

    Hello everyone, I'm new to all of this and new to this machine. I just purchased a 1986 john deere 410c 2wd backhoe and am having some issues sorting it out. It's my first piece of heavy equipment, and I'm now being forced to learn quickly about hydraulics in order to figure this thing out and...
