Right track no power boom no down pressure acc blade moves when traveling


Hi Rodney:
Sounds like an excavator with a bad pump.
Time to call a service technician (mechanic) who knows the machine.

Kobelco 120 excavator sometimes one track will not drive.


Filter or pressure relief valve, or track feed valve. Otherwise you are in for a big bucks drive motor.
If it were the pump you would have bad everything.

Can a track tensioners on a excavator seize as i can pump grease in and the nipple is fine ( not blocked)


If you are pumping grease in, the idler should be extending and the track should be getting tighter. If the piston is seized, you should not be able to pump grease into it UNLESS THE SEAL IS BLOWN in which case you can pump all day and the track won't get any tighter. The fix on a blown track adjuster seal requires removing the track to allow the idler and slack adjuster to be removed. Then unbolt the slack adjuster piston assembly and take it to your local heavy duty hydraulic shop for a rebuild.
This is HEAVY work. Take your time, think safety first, and ask for help if you need it. Keep in touch. I've done enough of these that it;s not scarey. What machine are you working on?

1997 Jeep cherokee larado squeals replaced the drive belt a few times and it keeps tearing


Inspect the belt tensioner for the following conditions:
Noise
  • If the belt squeals, the tensioner force may be insufficient. Check the belt length gauge, if the length is correct, replace the tensioner.
  • If the tensioner clatters or rattles during engine operation, there may be internal interference or wear. Replace the tensioner.
  • If the belt chirps, you may have a worn pulley or tensioner or cracks in the tensioner bas or arm. Check the mounting bolts, if they are okay, replace the tensioner.
Sticking or Seized Tensioner or Idler
  • If the tensioner does not operate smoothly or doesn't move, you may have: internal thrust surface damage/wear, internal damage/wear, or a broken spring, replace the tensioner.
Appearance
  • Inspect the tensioner arm for cracks or other damage. If the tensioner is broken, it should be replaced.
  • Look for excessive tensioner movement at idle, which can indicate internal wear, an out-of-round pulley or loose mounting bolts. Check the mounting bolts, it they are in good condition, replace the tensioner.
  • Make sure the tensioner is not tilted or misaligned. Also make sure a gap exists between the tensioner arm and base. If you notice a problem, check the mounting surface, it the surface is okay, replace the tensioner.
Belt Tracking
  • If the belt does not track properly on the pulley tracking surface, you'll need to troubleshoot the problem. Check the mounting bolts and the system alignment. Then, make sure the correct belt is being used for the vehicle. If all of these things are intact, replace the tensioner.
Belt Length Indicator
  • A belt length indicator is built into each tensioner.
  • The gauge identifies the effective operating range of the tensioner.
  • It consists of a pointer and either two or three length marks.
    • On a three-mark gauge minimum belt length, maximum belt length and ideal belt length are indicated.
    • On a two-mark gauge only minimum belt length and maximum belt length are indicated.
    • Ideal belt length on a two-mark gauge is generally half way between the minimum and the maximum.
  • When a belt wears and stretches with age the tensioner will move towards the maximum belt length to maintain proper tension.
  • As the pointer nears the maximum length mark, replace the belt.
