    Recently developed a leak out the ram end of my left front wheels steering cylinder. Have a weep in the other one so while I have time I plan on taking both in for repairs.

    Old JD 6059 fuel pump

    '79 vintage JD570A grader w/6059 engine won't start.. Mechanical fuel pump suspect as fuel from tank gets that far. Next in line after the pump is the glass fuel filter box which shows mostly empty and primer lever won't help. Turn engine over for ten seconds and no change in fuel level in...

    Would you buy this grader if it was manufactured today?

    Came across this in the The Dirt spring 2017. Preserving a legacy from the ground up the 570 motorgrader. https://www.deere.com/en_US/industry/construction/our_offerings/cer_archive.page Interesting that in the same issue they write about "the power to see through iron and steel " and the...

    I am looking for help finding a John Deere 570 A series parts source. The dealer quoted around $150 for a steering rod clevis that attaches to the steering arm on the right front wheel. I'm thinking that I might find a replacement for much less from a salvage machine or ? I did an...

    What is wrong with this picture

    JD 570A This is a picture of the return hydraulic line before it gets to the intercooler on the right. The line junction is right over the radiator. I've had several failures at this junction because of a jury rigged connection with hose clamps. The pressure in line varies with demand...

    New to Back Slopes

    Well I decided that if I was going to have a real grader experience I should do some back slopes. Having fixed my saddle pins retraction function and tightened up circle I put the 570A to work cutting in a new driveway for a neighbor which resulted in my getting to increase the sight distance...

    Coolant Flush for my grader

    Under "what should I be taking care of now" topic, I've been thinking coolant flush. This probably should have been done when I purchased the grader five years ago, but so much to learn. I could not find much info on HEF concerning this, so I thought it must be simple. Then I thought again...

    welding on the chain box

    My chain box has nine inch crack along the top inside weld that weeps a little oil from the box. Is it feasible to go over this with a new arc weld? Would I need to drain the lubricating fluid, (JD hydraulic fluid)? My JB epoxy weld fix cracked after a short time. I'm trying some plumbers glue...

    JD 570A Saddle pins

    I have decided to repair or replace a saddle pin cylinder on my John Deere 570A grader. We determined that the pin wasn't frozen in place when we were able to get it to retract with the aid of an air hammer while the saddle pin valve was depressed, (open). Examining the technical manual I...

    Time to tighten up the circle.

    JD 570 A - Need to remove some circle shoe shims as it's time to tighten up the circle. Dealer says up to twelve hours if I can get it there, (I'm twenty miles out with no SME plates or insurance). Problem is the eight 1.5 inch nuts don't want to come loose and were placed so you can't get a...

    Re using hydraulic oil

    Due to a return line break on a JD 570A and service records I decided it was time to change both hyd. oil and filters. The interval was around 1000 hr since the last filter/hyd. oil change. A previous return line break added about 5 gals. of new Hy-guard about 300 hrs ago. Records indicate the...

    JD Push Pull Cable repair

    The forward / reverse cable from the cab to the transmission of my 570A is taking too much muscle to operate. I priced a new one from the dealer and they come in at $250 or about $25 per foot. On the advice of a friend, I'm going to try and loosen it up and currently have it soaking in straight...

    Jaw clutch vs hydraulics

    I would like to know more about why the jaw clutch controls were abandoned for hydraulics. I have limited experience with the clutch control on the blade , (a Wabco and Cat 12). The Cat could be dangerous, however the Wabco never bit me. I really liked the way I could feel the blade screw down...
