1700 hydraulic problems

[wonl2]

Hello Forum Members, I have a 1700 that was sitting for at least 8 years. It several hours to get her started. The FEL and 3 pt worked sporadically at first, lifting the bucket a foot or so and also minimal movement of the 3 pt. I drained the hydraulic system and cleaned the filter. The hydraulic fluid looked like coffee with a lot of cream. The filter was also pretty dirty. I filled the reservoir with 28 quarts of hydraulic oil (5 quarts to accommodate FEL).
Everything operated perfectly while I operated all components through their range. I then drove the tractor approximately 100 feet. When I tried to lift the FEL or operate the 3 pt nothing worked. The tractor still would drive properly. I checked the hydraulic fluid level and the level was above the full mark. I let the tractor sit for a week and tried it again. Same results.

Is my pump bad or going bad? Should I drain the hydraulic oil again and replace with new oil? Any other suggestions???

Thanks for and and all replies.

Phil

Your new fluid may have picked up some sludge and clogged up the sump screen if your tractor has one.

Did you replace the hyd filter?

You may have air in the hyd system, and if so, keep operating to purge the air.

If your hyd. oil looks like coffee with a lot of creamer you most likely have water in the oil. After 8 yrs. condensation from temp swings may be the source of the water in the oil. I would start with changing the oil with some cheap oil and new filters. Then run for an hour to flush the system. Change the oil and filters again with the proper oil.

I bought a used BX that had the same symptoms. Took two flushing to get the crude out of the system.

The water in the oil may be freezing preventing the oil from flowing.
