Like learning washers, ALWAYS Face Up flat side down rails are Small or Narrow Link(Bushing) End Forward, Not so hard to remember.
What will be the end purpose, personal, few hours per operating season, dependency for a paycheck, private business? I have a antique hard to find parts for machine, is simplistic and seem to find MOST components I Need to keep it moving. That stated I depend for nothing of the machine it is a hobby and past time use maybe a few tens to a hundred hours a year.
Check for reasonably close proximity parts suppliers, also check on machine parts availability where some of these have gone to obsolescence levels. Komatsu is not known for parts readily available on a number of machines.
No pieces or extreme time factor to get or only well worn used may wish to stop, bite the bullet and arrange for rental of Newer NOT YOURS machines on as needed only basis and not have the investment may not be able to recover machine. $6K on one two or even three occasions where you supply fuel and add oil and grease ONLY could be beneficial.
I will keep it a year or two to clean up 15acres from a tornado that went through. I am finishing clearing the trees and will dig a pond with my excavator. So will need the dozer for final grade and cleanup around trees. I have been looking for a while and not much around for under $20k. Just thought some feedback on this unit if there is anything i should look for if i go see it.

Hello folks,
I was having a problem with the oil pressure light coming on my Dozer, I installed a new oil pressure sender (Komatsu part) and the light still coming on, I like to test the engine pressure so I went to my local auto parts store and the guy said that first I had to find out how much pressure this engine should read, does anyone know what the normal pressure should be? or the best method to measure it? I imagine that I need a pressure gage and connector with the metric hook up and hook it where the pressure sender is now?
Right now, when I turn the engine on the low pressure light will be on and off and will turn off if I depress the clutch every time, but will comes on/off again if I move the dozer around
The engine only smokes at start, after a few minutes no smoke at all...unless when I accelerate hard and I see some black smoke puffs initially and clears.
I have change the engine oil couple times, seems like right after the change the light stays off but after a few hours it starts coming on again and the new oil is very dark already.
I would greatly appreciate if someone could give me some pointers on this.
