Used my gear oil dispenser today and thought I would share one of my favorite cheap tools. I bought the used fire extinguisher locally for $15. Filled it up with gear oil, pressurized it, and a few years ago ended up taping a Gatorade bottle on the side to collect the hose dribble. In the winter, you need to being it in somewhere warm before you use it the next day as it sucks when it is cold.
There is nothing worse than filling Trans, TC, diffs with gear oil. I feel like pop eye when I'm done. Looking for anything that works better than the hand pumps I usually use.
yep, pressurize with shop air....fill up to the gauge on the tank in the green zone. As mentioned in the first post, make sure you take it into the house the night before if your garage isn't heated in the winter as the gear oil gets stiff.
I filled the front diff on the 80 with no pumping and within about 30 seconds...
it is the way to go...
a shorter tank would fit under the truck better, but one of my trucks has 35s and the big tank stands upright. 315s on an 80 require you to tilt the tank slightly...
PS - Snobdds - I miss living in wyoming...I would love to hear where your trucks been throughout the state...
Many years ago when we ran a transmission shop I made one out of a small block Chev oil pump. It fit on a 20 gal drum of 80-90 with wheels to move it around the shop. It had a drop leg ( as long as the drum was high)on the input for the pump that was welded to to the 2" drum bung. The drum bung was steel, most are pot metal. The output had a nipple and a hose with hook shaped spout on the end that fit in the transmission /diff fill hole. The was hand crank welded to the input drive for the pump. It worked extremely well and didn't take too many turns to fill most transmissions.When we got a new drum of oil we just removed the pump assemble from the drum and put the wheeled dolly on the new drum and it was ready to go. Sorry I don't have any pictures. The rig went with the shop when we sold it back in the mid 80's.
Also used a small block Chev oil pump for transmission oil cooler flusher. The pump was mounted on the same type of 20 gallon drum with 1/2 hp electric motor to drive it. The pump was in the bottom of the drum with varsol in it and the drive shaft came through the top of the drum to the motor The drive shaft was 1/2'' shaft joined to the motor and the pump with a short piece of hose and regular hose clamps The bottom hose that was submerged in varsol use to need replacing ever couple of years as the varsol would eventually make go soft. It went with shop as well.
Used to get used SB pumps for free from a guy the rebuilt motors.
