Buying a used excavator - what to look for? Dont get fooled by shiny paint

?Providing outstanding amazing values through process clarity and improvement

Our experience with the PC 30 at Morong says that dont be fooled by looks

Bring a mechanic, and inspect:

     1.  Number of hours (most remove the odo and say its 1,500 hours or less;  (probably understated by 4,000 hours)

     2.  Check the under carriage:

          1.  The sprocket

          2.   The rollers

          3.    The pins    

                if 2 and 3 are shiny, then its worn out

         4.    The tracks  -  do they move or slide a lot

                                      are they 5 to 10 mm in height, if less the machine is worn out

         5.   The final drive motor (unscrew the cover and check for rust or worn out hoses)

    3.  The engine:

        1.  The oil -  looking black

        2.   Vibration

        3.   Leaks

        4.   The filters

    4.   The hydraulics

       1.  Check the hoses and fittings for leaks

       2.   Check the fluid level

       3.   Check the filter

    5.  The boom and stick

      1.  Are there leaks in the hydraulic hoses?

      2.  Are there cracks anywhere in the boom and stick

      3.  Try to move the boom left and right with bucket on the ground.  See the play/or listen

    5.  Operation

      1.  Are there unusual noises when the motor are running

      2.  Are the boom and stick loose or vibrating

      3.  Does the machine move fast or slow?

      4.  Tilt the unit sideways, forward and backward?   Can the pressure hold out for more than 30

           seconds.

Process - Excavator Changing conversion from Steel to Rubber tracks, installing rubber track pads.

One of the contentious issues in excavator purchase is that the steel track can damage the grass  Our discussion with mechanics of BH at Guagua (Jeff) are as follows;

1.  Rubber tracks are slippery and thus are not recommended;    rubber isi good for concrete roads. It is better to use wooden materials for navigating grassy landscape.  Steel track will slide on ubber matting

2.  It is better to install rubber track pad on steel tracks.
