One lever engages the PTO, the other controls the up/down action. You have to figure which is which. | | | | | Joined: Jun 2005 Posts: 125 Wrench Fetcher | | Wrench Fetcher Joined: Jun 2005 Posts: 125 | Without some pictures it's kind of hard to tell what your set up is but I can tell you how mine works.
WARNING: MAKE SURE YOU (OR OTHERS) DON'T GET UNDER THE TRUCK BED WHILE IT IS IN THE RAISED POSITION. BLOCK THE BED UP WITH A 4X4 OR SIMILAR BLOCK IF YOU NEED TO WORK ON THE TRUCK WITH THE BED UP THEN LET THE BED "REST" ON THE BLOCK(S) SO YOU KNOW IT WON'T GO ANYWHERE BEFORE CLIMBING UNDER THE BED. FAILING TO HEED THIS WARNING COULD VOID YOUR BIRTH CERTIFICATE!!!
1. Set the e-brake to keep the truck from rolling. Blocking the wheels is a good alternative if the e-brake is questionable or you just want to be extra safe. 2. With the engine running, place the transmission in neutral. 3. While holding the clutch in, pull the knob on the dash out to engage the PTO and then let the clutch out. (PTO is engaged and running now.) 4. Push the lever on the floor close to the driver's leg back towards the seat until you reach the desired angle or height. 5. Let the lever return to it's "neutral" position. If there's no spring on the lever, you may have to place it back in the neutral position. 6. After you have dumped the load, reverse steps 2 and 3 to disengage the PTO and reengage the drive gears.
7. To lower the bed push the lever by the driver's leg forward until the bed returns to the down position on the frame. If you used blocks to support the bed, you'll need to raise the bed and remove the blocks before lowering.
My apologies if I've included obvious actions in some of these steps; but I do technical writing as part of my work and I've learned not to assume any particular level of competency while describing steps in any given operation.
BTW, that's one nice looking big bolt! I can't wait to get mine back on the road. | | | | | Joined: Dec 2003 Posts: 2,733 Shop Shark | | Shop Shark Joined: Dec 2003 Posts: 2,733 | You'll need to get under the truck and see which lever is hooked to the PTO and which goes to the pump valve. If everything is working as it should you may wish to put labels on them or on the dash to guide you. It is doubtful that the valve has any return to neutral feature. Most of them had spring detents on the spool which kept them in the position in which they were placed. | | | | | Joined: Apr 2005 Posts: 1,107 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 1,107 | i have a gallion hoist on my 51 6100. the lever on the left operates the pto. in the forward position it does nothing because the pto is disengaged. when pulled to the rear about an inch, it engages the pto and spins the hydralic pump for the hoist.
the lever on the right when in the center position will allow the box to raise and will hold the box in place. when moved to the rear it will drop the box and im told that when its pushed forward it will lock the box in place however i do not trust it and use lumber to prop it up for working around it. as i do not want to void my birth certificate as stated above | | | | | Joined: Jun 2007 Posts: 85 'Bolter | | 'Bolter Joined: Jun 2007 Posts: 85 | Both mine have the cable with knob on the dash to engage the pto and then a lever down on the floor to operate the hyds. One has it on the floorboard the other to the left of the divers seat. I haven't had to add oil to either of them yet but braceing the bed up with blocks is a MUST!!! I have heard a couple fatal stories. Those hoists seem to be pretty much trouble free not much that can go with with them. | | | | | Joined: Mar 2005 Posts: 1,029 Member | | Member Joined: Mar 2005 Posts: 1,029 | Maybe one lever is for a 2 speed axle? All you have to do is crawl under and see what they attach to. | | |
