Pressure falls off from pump of bolens ht20

Should test your transmissions front pump for pressure take the two transmission lines off the radiator and run them into a 5 gallon bucket and start it and look in the bucket and see if you have pressure coming out one of the lines if no pressure or weak pressure front pump is done look for a replacement most older transmission can have reverse and no forward gear due to lack of pressure or low fluid level.

Check pressure from pump.

Check the level of oil in the hydraulic tank.

Seals are gone in pump and allowing flow back into holding tank if it is not seeping onto the ground

fuel supple issue-as shown be replacing fuel filter and seeing an improvement-next thing to try- put a new fuel pump in- Denny

Change the filter. If you can lower the loader by loosening a line at the valve, suspect the valve. All lines usually dump to tank at the valve. Make sure that line is ok. If any valves are electric, suspect them even more.

unplug the washer take off the bottom kick plate of the washer. behind this you will see the pump unscrew the cap and pull it out there is a trap attached to it to catch the debris that falls down. Clamp off the hoses going to and from the pump. If you dont have a way to do this make sure to have rags and buckets around to catch the water. then reach in and pull whatever is in the pump out of the pump if you feel comfortable with skills you can take the pump apart to clean it. Only do this if you are sure you can put it back together.

Assuming that you have a pressure gauge to determine actual system pressure. Without pressure gauge, you could use the sound of the engine as test for capacity pressure (if engine and pump are paired correctly, engine will labor at full throttle under high pressure). Using your machine at rated capacity will decrease the life of the unit. Better to use at 75 ~ 80 percent of cap. (2500psi on your unit). Pressure is developed thru the restriction of the tip/orifice assuming that the pump is working correctly. Tip should be correct for the capacity of the pump. Check the pump capacity for gpm (or test by removing tip connect water supply, then with engine running, catch water in bucket for exactly one min. and measure quantity). Example, 4 gallon per minuite should use a tip with 4gpm markings. If wrong tip size is used, (too large, low pressure, too small, pump will go into unload condition resulting in low pressure) . If thru testing you determin that the correct size tip is installed, suspect valves or unloader. Leaking valves or orings that seal valves will cause low pressure and also cause a pulsating sensation. Worn unloader will cause pressure to rise and fall in a slow cycle. Good luck with your repair

Backhoe will not move at all

Look for the pump, take the hoses off it and check for clogs. Have a bucket ready to catch the water. Watch the pump while the machine is running, make sure it is spinning.
