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
