More fun.....pump goes

[MossRoad]

The way I look at it, if the tram pump blows up and spews metal, there's going to be metal in the circuits to the wheel motors, the cooler and back to the tank and all associated hoses. Once metal is on the tank, there's a chance it will get sucked into the two PTO pumps, isn't there? Only the charge pump for the tram circuit sucks through the filter as I understand it.

Anyhow, best to ask Terry at Power Trac, but I'd be cautious.

I've got 2 more hoses to get off.......finally got my driveway plowed so I can get out. That 1 1/4" nut was a problem as I didn't have a wrench that size, my crescents don't open wide enough and I couldn't fit a monkey wrench in so finally being able to drive out again I went and bought a 10" crescent with a 1 5/16" jaw that should just fit in the space where this hose is located off the pto pump. Once thats off I hope to be able to get to the last hose buried on the bottom.......man they don't make this easy.....haha. Then I should finally be able to get the pump off and talk to Terry.......I'll let you know what he has to say about flushing the system........Jack

Oh yeah I had to drain all my oil. Gravity will push it through the hoses and it will be every where. I used clean 5 gallon buckets to drain mine into. Found that metal shavings drained out and they all sank to the bottom of the buckets. I reused my oil but scooped the oil out slow so the shavings would stay in the bottom of the buckets then topped off with new oil.

Perhaps a magnet or two in the bottom of the buckets?

All the best,

I would pump it through a filter too if I was going to reuse it but new oil is cheap compared to a new pump.

Yeah... 40 micron is pretty small (which is what I think your PT filter filters at), I would chuck and replace unless budget is tight. Magnets would be the tight budget solver.

The standard NAPA filter is 30 microns. I doubt that the PT is significantly different. Pump manufacturers don't recommend finer filters in suction uses because of the risk of filter collapse and cavitation.

All the best,

Peter

Yeah, sorry. what I was getting at was that just because you removed the shavings in the bottom doesn't mean you got all the metal particles out.

Finally got the 1" hose that runs from the oil tank to the pto pump off......it's located in such a way that its impossible to get any leverage on the wrench. Only hose left is one going to the rear wheel motor.....which is connected to a manifold on the bottom of the pump....and of course you can't get a wrench in there either with all the other hoses and rps valve in the way. There is a bit of play with the hose so I may just pull the pump off the motor mount with it on and then turn the pump on its side to remove it.

I went out and got hex plugs for the hoses so leakage has been minimal up to this point.......although it does seem to always find its way onto the floor.

If it ever stops snowing I'll be able to spend some time on this tomorrow and get the pump off.......but I've had to resort to re-installing a plow on the riding lawn mower......which can only handle 3" max of snow at a time.........and takes 2+ hours to plow the drive each time........so have been spending a lot of time with snow removal now........just seems like every day there's another storm........dam groundhog........haha
