Takeuchi mini digger tracking problem

Pressure valve? does it only do it to only one side? Left or right. The reason you move both tracks with the bucket running is because you relieve pressure. One side is free wheeling, As they call it. I work on cars, But also have done to many hydraulic components. You have a pressure control valve that is bad.

Hydraulics just stopped all of a sudden with bucket up. it will not move at all. what is the trouble shooting steps to follow

SAFETY FIRST!!!!!!!!!!!!!!!
The bucket up is DANGEROUS!
Get some blocking under it before you do anything.

If it were me, I'd find a way (Winch, Crane, Other machine, ???)
to safely support the bucket, then find a way to bleed the lift cylinders to allow the bucket to be lowered to the ground.

Then and ONLY then, I'd be looking at the hydraulics functions to determine if it was a valving or pump problem.

My fan runs but the compressor does not start on my whirlpool model ad25bsro so no water is collected.

1st ck that the bucket full light is not on , reguardless if bucket is m/t and in place , if light is on then the float sensor inside bucket container needs looked at , if no light is seen then it's common on new units to run the circulation fan all the time , and cycle the compressor on the humidistat's setting , reverify what the settings are for your room , std setting is 70%rH for a home , also a seperate meter to indicate %rh might help to determine if your unit is working properly (there not expensive) it migtht be that your room is dry enough and unit is not calling for water removal

Do I have to split the track to install new bottom rollers on my E70B?

If you remove the plug for the grease cylinder on the idler arm and squeeze out the grease manually by pushing the pulley wheel in, you can relates enough tension on the track to sag it down and maybe remove rollers. Or you can remove the track this way with a little manual labor without splitting it.

I have hydraulic oil in my radiator, e70b

I am not familiar with that particular machine, but I believe it would more likely be diesel or motor oil, unless of course there is a water exchange hydraulic cooler. If there is, check that for a leak to the coolant. If not, I would check compression on each cylinder, and/or look for signs of a blown head gasket. Other possibilities are probably more serious than even that. I hope this is helpful.

Cat e70b wont start

Check the glo- plugs are working and check that the batteries are spinning the motor fast enough. Diesel engines need quick revs to heat the combustion air hot enough to ignite the diesel spray. If the engine is old you may need to have the injectors done as they have to atomise the fuel and not spray it in
