Low hydraulic pressure to raise implements 8650 john deere


Could be the charge lube in the rear differential. It supplies oil to main Hydraulic pump up front on engine. The charge pump drive can strip and not turn pump. To remove pump drive remove third link plate on rear frame, remove plug behind plate, pull out hex shaft, about 5 foot long and inspect.

Lose press on retrn to pool using Hayward S166t with brand new veri flow pump attached. I back wash and pressure restored is excellent but within 15 or twenty min drops off again.


what is the water like?
Dirty? Green? Murky? Cloudy?
Something is clogging the filter!

Let me ask this, you said: "Pressure drops Off" ???
Do you have a pressure guage on the filter?
Does the pressure increase? Or does it Decrease?
This will be an important piece of information!!!!
  • If pressure increases on the pressure gauge...
    • then filter is working and filtering out dirt and filter is clogging up.
  • If pressure decreases on the filters pressure gauge,
    • then the basket, or literally anything that is decreasing or stopping the water from getting to the pump, or more precisely to the internal impeller of the pump!
Most commonly - plugged impeller, baskets need to be checked, enough water in pool? etc.

When I drive oil pressure goes up 10 every 1000 rpms


Nothing wrong with that, your oil pump is geared to the crank shaft. The higher the revs the more oil is being pumped by the oil pump. The oil galleries are a fixed size so as the flow increases the pressure rises to force the increased flow through the same size oil galleries. You should also notice that you oil pressure is 10 to 20 psi higher when the engine is first started and every thing is cold.

My 2006 Pontiac Torrent lose power when I reach the speed of about 75-80


That is an odd bit of advice. If the oil pump was working poorly enough to cause a noticeable difference on engine performance, then you have already ruined the engine.

Although not always the case, typically if you are losing power as you increase speed, it is a fuel problem. Fuel pump could be going out. Inline fuel filter could be dirty and restricting fuel flow. Intank (gas tank) filter could be clogged and restricting fuel flow.

Regarding your oil pump, you can check to see if it is working correctly by installing an oil pressure gauge. You might check to see if your engine has solid lifters or hydraulic lifters. If it has hydraulic lifters, your engine will develop a tapping noise when the oil pressure is low because the lack of oil pressure creates a lack of hydraulic lift in the lifters and so they collapse creating a gap between the lifter and the rocker arm. This gap means that the rocker arm comes off the lifter and then smacks the lifter when coming back down resulting in the "tapping" noise mentioned.

Not putting out enough pressure or flow to pop up sprinkler heads


Have you fixed this problem?
Q? Did you replace an existing pump. And what was the model and did it work.
Q? If its the same size as the fp4032, has anything else changed? Is there a filter that needs checking.
hydraulically to work it out I need the distance from pump to water, height and size of pipe. Distance you are pumping too, height and size of pipe. And what the "four heads are"? Nozzle size etc. To work out a flow/pressure rate.

I have a Kenmore Refrigerator: Model Number 106.50254001, Purchased 1-24-2001. It has a water and ice dispenser on the front. I purchased a Rainsoft Water Softening system, with a Reverse Osmosis System...


The water pump probaply is switch on by a flow switch. So the solution is to install a pressure tank after pump so to have stable pressure and not a pulsing one.

Pool heater will not fire up


Check for proper flow at your pump and at the return jets. You have to sustain proper water flow in order of rthe heater to function properly. If the flow is adequate, then use a jumper lead across the pressure switch terminals on the heater and see if it will fire and remain on. If so then the pressure switch is either faulty or you have a flow problem which is not generating enough water pressure to trip the switch. DO NOT adjust the pressure switch, as it is factory set. Check your pump for a clogged inlet or other possible blockage before the heater.

Low oil pressure 93 GMC P/U w/350 motor w/205,000 miles gauge


While engine is running, open the cover where you add oil to engine and see if you see a good flow of oil, if good flow, could be as easy as replacing oil sending sensor. got to realize that if poor maintenance history your engine may not be building enough pressure at iddle to move your hydraulic operated valves, only when you rev it up it will pump enough to run smooth. if running engine too long, you may cause more damage to other engine components such as crankshaft and cam shaft bearings. if you can spare a few bucks, have a good mechanic check your oil pressure with a mechanical gauge. another cheap option is to replace oil pump. last resort if you love your truck as much as we do,replace engine or rebuild it. At 205,000 this is a normal symptom, other than timing chain problems, most engines don't make it that far. hope this helps!
