653 dozer

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hey guys, I've got a couple of issues with my 653. It's a pedal steer and I do not know if the problems are related. The left pedal does nothing when depressed, it goes down and nothing happens. I believe it might need new new brake linings? The right steering pedal will turn the machine but reluctantly. Also when I use the shuttle sometimes it won't move. If I go from forward to reverse, it often will not respond. If I continue forward using several attempts, it might then go backward. It pushes like a demon, but when going up and down inclines it slows dramatically and won't even move in 2nd or 3rd gears on a slope. All the fluids are up to par. Was gonna test the shuttle pressure, what do you think? Thanks.

	Dozing in 2 nd or 3 rd ? if pushing use 1st unless your in a hurry for some reason . Sounds like more than brake band problem - then if bands are oil soaked - they will not turn good . It sounds like the need to check pressures and to also make sure your valve body is working properly - I had broken spring on the reverse side in valve body - machine quit in that direction as everything did not line up to send oil to right ports for clutch pack . Check those springs to make sure both are same length and strength.

	No, not dozing in 2nd or 3rd, just seeing if it would move in those gears or even try to move while on an incline. The road goes through a slight dip.

	DID YOU TIGHTEN THE BRAKE BANDS ? TAKE TOP COVER OFF THE FINAL DRIVES AND LOOK TO SEE IF INSIDE IS COATED WITH OIL.

	I have not yet tried to tighten them, but will pull the covers ans inspect/ tighten them. Any thoughts on how to determine if the problem is the clutches or just the brake bands other than trial and error? Also my shuttle is acting up a bit.

	IF THERE IS NO MORE ADJUSTMENT ON THE THREADED ROD FOR BRAKE BANDS THEN THEY ARE WORN OUT AND MUST BE REPLACED. I DO NOT THINK PUSHING DIRT IN 2 nd OR 3 rd GEAR IS GOOD FOR THE MACHINE. THOSE TWO GEARS ARE REALLY DESIGNED FOR TRAMMING ONLY IN MY OPINION. I BELIEVE THE REAL PROBLEM LIES IN ADJUSTMENT AND INSPECTION FOR OIL ON BRAKE BANDS.

	Guys, let me clear this up. I am not pushing dirt or working the machine in 2nd or 3rd. Simply stating that on an incline it slows to a stop in those gears, but on a level surface when the shuttle is working, it will move ok. In 1st gear it will push more than adequately.

	COKE IS RIGHT ON A CHECK OF PRESSURE. THEN GO FROM THERE. I STILL THINK AN INSPECTION OF FINAL DRIVE INSIDE OF CASE IS IN ORDER AND NOT TOO MUCH TROUBLE TO REMOVE THE COVERS.

	I have a 653 also............almost the same problem...........only I am leaking dexron torque housing fluid though. I was curious as to what you found out with your troubleshooting. Mine smokes also because of running sooooo rich and I have to find a way to lean out the fuel to the engine. I think my injectors have stacked washers under them when I installed them. I don't know much about diesel engines, but I am learning.

	Does the 653 dozer with the 433 engine have an injector pump that is adjustable. It seems to be running really rich. If I push the fuel shutoff knob in to bring the idle down then it leans out and runs better without all the smoke. I am at a stand still with the dozer until I can get more information. Thanks.
