Discussion:
mast lowers very slowly

When lowering the mast it started intermittently lowering slow to the point of being unusable. Now it will not lower the carriage after the second stage has lowered.

On the bottom of the control value just above the solenoid on the bottom of the lift spool there is a small bolt that when removed allows the mast to lower at its normal speed all the way down, but with the bolt removed or even loosened it will not raise the mast if it does it is very slow to do so. The solenoid is receiving power and when the key is off it will not lower at all as is normally the case.

I think that the solenoid is not opening fully as it should causing the mast to lower very slow. Just wanted to know if anyone else had this problem and if it was the solenoid. Also if anyone has the part number.

Thanks in advance.

Well it was the solenoid. It was sticking and restricting the flow. Replaced with new part and works great. Thanks for your input.

Hello,

there is a flow control valve inside the up down spool. The spring inside was known for breaking in two jamming the down side of the valve.

Let me know if that helps. Usually it is easier to remove the valve assembly from the truck. It was a tech bulletin on the 8fgcu25.

Fact of the week
Bluetooth is named after the 10th-century Viking king, Harald Bluetooth, who united warring tribes in Denmark and Norway. In 1997, Jim Kardach from Intel gave the name to the technology because of its ability to unite different communication protocols, just as Harald united various tribes.
