Hi folks - need a little help with what the hoist should sound like! The link is for a video of the hoist running - a couple folks on Facebook thought the hoist is making a bad sound. I have no real idea of what it should sound like. I've been around some much larger hydraulic pumps (much louder), and have a brother in law with a fleet of modern dump trucks (also loud). So my initial thoughts were that it sounded ok. Now I'm not sure, and of course do not want to hurt anything. Also, I do not use the hoist often at all.
So if you have an idea of what it should sound like, and don't mind giving it a listen, I would appreciate any feedback.
Thanks Paul. Previous owner said he checked it, and I have been dumb enough not to because I'm not sure how......
I know the cylinder is the reservoir, just not sure if I should check with the dump up or down.... got to admit I am afraid to check with the dump up even with supports!
Anyone have good advice on how to check? Also - what fluid what it use? I'd imagine you do not want to mix fluids, and I would have no idea of what is in it.
I am not sure about "new" perfection hoists, but old GI trucks like mine did use that brand in some dumper contracts. My dumpers are made by Hercules, but the technology is much the same (as well as all non-external reservoir systems made at that time period). I have included an image for a circa 1942 perfection ram. The fill plug is at the top rear labeled "air vent plug". Since yours is only 10 or so years diferent, it may be similar, or even the same Filling them is much like a hydraulic bottle jack...full is fluid dripping out of the fill hole when the ram is in the completely down position. Filling to the full level is rather difficult when the bed is down.
I fill mine by using the following process: 1) raise bed about 1/2-3/4 2) chock the ram at the bed hinge (both sides) with short sections of 2x6's stacked on top of one another 3) for extra protection, set 2x4 or 4x4 posts a suitable length so that they extend from the ground to a ribbed support on the underside of the bed. I like to have one on each side of the truck...a decent knot free SPF stud is adequate provided that it cannot kick out when the bed is lowered. 4) lower the bed so that it rests securely on your wood members (2 and 3) 5) shut down engine and remove the fill plug 6) fill the cylinder with a AW46 type hydraulic fluid leaving the plug off at this time 7) raise the bed to remove your wood members 8) raise and lower the bed several times to evacuate air out of the system and to puke out excess oil 9) raise and chock bed once again and reinstall vent plug 10) clean up the mess that was made from the purging of excess oil.
I would start by just adding about 1-2 quarts and watching to see what spills out when you cycle the bed up and down. Add oil as necessary. I don't think it is necessary to purge the system. A gallon should be adequate as a dry system only takes about 2 gallons.
I hope this process cures your whining pump gear issue, and I feel it is highly probable that it will.
Thanks Frank50. Got to be honest though, there are days when I want to remove the flames, and then other days when I like the character they add. The flames are actually done very well, but when I bought the truck I swore they had to go.... now they are growing on me.
