used motor oil in dump wet kits

wilson ind · Feb 23, 2012

When I was running 4 coal dumps I was complaining to good friend about driver letting hose drag and loose 50 gal of new oil from 1 month old wet kit. Friend who had over 100 units and bought tractors in groups of 5 asked why I was using new oil. He put used oil in new wet kits and had for years. Never had a problem. Think about it, pump oil 2-3 times aday for 2-3 min. He retired a very wealth man and not a fly-by night operator. OK beat me up on this!!

Perhaps he was talking about used Hyd. oil not motor oil ?

We did and do the same thing in a 10 ton forklift. It has worked for last 10 yrs. No sense in putting new oil in if it is going to leak back out.

What is a "wet kit"? I've never heard the term used for farm tractors before. Is it the hydraulic system on dump trucks/trailers, that only runs occasionally when the transmission PTO is engaged? Thanks.

Early farm tractors recommended motor oil (new & clean) in their hydraulic systems until about 1960. I'd use the recommended oil in a new equipment until the warranty expired, but on an older leaky system it would be economical.

If he filters the used motor oil or lets the water and suspended particles settle out before he puts it in a hydraulic system it could work well in such a lightly used system. He probably doesn't bother with changing the hyd oil either, just crack the drain plug to drain out the water before winter?

Sounds workable.

Wet kit ???

glennster · Feb 23, 2012

around here a "wet kit" is an add on hydraulic unit to allow a semi tractor to operate a dump trailer.

I wouldn`t do it, but most of my side dump work has been short haul, 20-30 trips per day, with lots of spreading, and the oil gets HOT! A PTO pump is anything but cheap anymore, and as long as no one gets stupid and tears off a hose, the hyd. oil is a very small portion of the budget in a trucking fleet. Seems like too much of a risk, and it also prevents you from ever hooking on to anyone elses trailer who does not want junk oil in there rams.

If the oil will no longer serve to lubricate the engine you drained it out of, why would you expect it to lubricate a pump with as tight or tighter tolerances than an engine?

Perhaps I shpuld add the procedure we used was put used oil in 55 gal barrel let sit undistruber for min 1 month pump off only top 3/4 NOT MOVING BARREL before pumping put botton porting on gravel road

Thanks!

Where we wanted the long haul drivers to make good time Put driver in adult depends they were only allowed to stop for fuel, then change depends

Don't think they mean that type of "wet kit", Wilson- LOL

Either you guys must have paid really well, or jobs were really scarce- about the time my boss started handing out the Depends, I would have been starting out the door.

"as long as no one gets stupid and tears off a hose"

That's asking a LOT of a typical crew. You'll always have some joker that didn't show up with his head screwed on straight, and manages to break the unbreakable.

sixtyninegmc · Feb 23, 2012

Yeah, I realize if it can be broke, a trucker will break it. Still, I would rather risk the loss of oil than burning up a pump. I try very hard on trucks and trailers that I maintain to route the hoses so they can`t easily be snagged, bungee them up the best I can, but there is always a way, for sure.

I have 4 here at the farm and all are late model units. We usually start out with new oil but never had any problems adding used oil however our used oil is strickly contained. First we drain it in to 55 gal barrels. Rack the barrel with the smal bung down and after 3 weeks we drain off any water . Then we filter and put it in a storage tank. Our shop has two large Clean Burn used oil heater. Cheap heat.

fixerupper · Feb 23, 2012

I'd be a little reluctant to put used in a wet kit that runs hyd motors like a feed trailer or a hydraulic PTO running a pump on a bulk liquid trailer. They're pretty hard on the pump because of the long running time during unloading. Can't do the motor any good either. Jim

I bought a used tandem gravel truck with a new box and hoist in 2004. It had new oil in it then and I have never added oil to it since. The truck gets used quite a bit, but probably never more than 25 loads a day. I would not even think of adding used oil to it. However if I tore off a lot of hoses I'd think about used oil. Also if you had one that leaked enough to think about adding used oil the DOT wouldn,t like it, also would make a mess on the floor if you left the truck inside.

It aint just the crew... How about the owner? It only takes a split second of brain fade... Thankfully, only three times in 35 years have I had to look in the mirror in dismay, right after I detached my lowboy, to see the air lines and the light cable dragging on the ground.

The owner just has to screw up once in a while to make the rest of us feel better

My old boss always used to jump on people to use both mirrors, then got in a hurry and only looked at the drivers mirror pinning a trailer, ripped the fender off one of our brand-new freightliners and totaled his own car. He caught a good bit of grief about that one.

Seems like it would be awfully thick in the winter. Mine takes forever to settle down in the winter with regular hydraulic oil in it.
