460 Hydro Questions! Please help

Matt in MO · Apr 20, 2014

Bought this tractor 3 years ago from the original owner. Pump started whining and decided tonight to drain it. It was the color of milk. Ouch!

1st ?- it had a WIX 51469 hydro filter in it. Is this a good filter?

2nd ?- the hollow that runs through tractor between the pump and the filter has these little raised spikes all in a line. Am I missing a piece of tube?

3rd ?- is there a good way to flush the whole system before adding new filer and Hy-Tran.

Thanks!

We had an 856 that had water in it like that setting the oil would look fine drive it a couple hundred feet and would be white. We just let it simmer on the stove in a kettle for a bit and evaporated the water out. This would work good to flush the system then change the oil this way you can remove the water without all the new oil cost. otherwise you will have to change the oil then change it again after you pump the new oil through the system to flush the old oil out. At 10.00 a gallon or there abouts the heat and flush by running for an hour is much cheaper. Then put your new oil in with a new filter.

That must have been some kettle. :>)

I worked for 25 years in the engineering experimental lab of a hydraulics company. Every so often in our test machines we would get a leaking heat exchanger. It's darn near impossible to boil all the water out... we would take the lid off the reservoir and heat the oil with the reservoir heaters to about 250 degrees, run the circulating pump (pump for heat exchanger and filters) and it would take days to boil the water out. Sometimes we did not have the luxury of taking that long, so the best bet for us was to drain EVERYTHING, all hoses, pumps, reservoir and put in fresh oil. I realize you can not hope to drain everything in a tractor like that, so I'd drain what I could, external lines, filter, etc., put in fresh and go with it.
Problem with water in the oil is it's like any other contaminant, especially under high temperature and high pressure... it will erode components. A pump with 4-5000 psi and water will erode just like if you threw sand in it.

Hope it wasn't their copper kettle used for making apple butter. Hal
