I recently bought a 2002 New Holland Ls170 Skid. It has about 2400 hrs on it. This afternoon, I was picking up prickly pear in a field when the skid suddenly would only roll about 5' forward or backward. It felt like it was binding. I took the chain cover off and found a (approximately) 1-1/4" dia. X 3/16" thick washer between the rear chain and sprocket. The washer was pretty well mangled. Also a 3/8"X3-1/4" bolt was laying in the bottom of the chain box. As far as I can see, no damage to anything other than the washer and bolt. The bolt is a grade 5 hardware item, but the washer will have to be ordered. The bolt and washer retains the brake rotors to a spline shaft. I am going to try and cut a new washer from some A36 steel shaft that I have as the original seems to be pretty soft.
My first question is, how do you determine if the chains are adjusted properly (they seem to have a lot of slack in them) and how do you adjust the chains?
Second question, what is the "industry standard" life of a skid loader in hours?
