Pump to fill rears and transmission

Most containers for oil are NOT built for pressure. I have done it i was growing up on a broke farm. Inevitably you’ll make a mess trying to get it to transfer faster.

As of 10 years ago, Lincoln still had cast housing hand pumps built to last. They even have valves in the ends of them to keep them from dripping. The other mechanic in the shop removed it because he thought it was too hard to pump through, but it was nice for a while!!! They are little pricey, but if/ when they leak a $20 o-ring kit seals them up again.

If your looking to do the job cheap, the suggestion of a harbor freight drill pump is your safest bet to not put your expensive oil on the ground .... and walls... and Truck.....and yourself!!!!

As with anything harbor freight, it might do the job perfect, might not at all, or may do it forever. It’s the luck of the draw!

 

You cant pump fast enough to get in trouble with the bike pump. Compressor is a different story even regulated.

Remember the only way to STOP the oil flow is to vent all the air out of the vessel. A tee and a ballvalve to atmosphere is your friend.

 

I’ve got two of these type in my shop, one for 75w-90 the other for 50w. Cast housings, solid build, smooth operation (with oil anyway).

I’m still digging for the exact part number on The Lincoln website so you can google pricing. The model in the pic is for Refilling grease guns and only pumps 1oz per stroke. I’ll have to get a model off the one in the shop. The ones I have move more fluid.

 

I want to say the last time I bought a genuine gear oil pump, complete with top for a 5 gallon bucket and hose with curved tip, the price was under 50 bucks. I don't think any of mine are lincoln and I know they are not cast, but 2 of them have been in regular use for close to 20 years. The other one I picked up at a garage sale or auction or something like that used, and it still works fine too.

 

what i did, was bought one of those little harbor freight sandblaster tanks and instead of sand in the tank i put the oil, put around 40 psi into the air connection and it just pushes it out pretty quick, but be ready to let the air out once u hear it gurgling cuz its empty

 

Remembered get these picks. These are the pumps I have. We added about 3ft of hose to them. I think I got them in 2015. I can’t see why they wouldn’t be available anymore. Nice operation, cast and heavy. O-ring seals let just a small amount by and unlike the cheap ones, you don’t have to mess with adjusting the shaft seal to find the sweet spot between to hard to pump and leak more on the lid than your putting through the hose.

 

Mine are cheaper ones, I have not had any trouble with them leaking, what I have had and it was my fault, is mine has cheap clear plastic hoses, they work and get the job done fine, but are just slipped on. I got in a hurry and started pumping fast and blew a hose off, making a mess, No complaints other than that, and I just never made that mistake again. lol

 

Don’t get me wrong, I got by a lot of years (about 10 of them)!with the less the expensive pumps. $50 here, get pissed off at it leaking out of the stem, $50 there, get pissed off that the hose was hard and kinked. And I finally decided it was time. I had only had seen 1 pump that was meant to pump gear oil with no problems. Dad had bought from an auction years before me and I had thought all new pumps should work the same way......

To sum it up:
1: If your working on 1 truck, go to harbor freight.
2: If your working on your own Fleet, buy the Lincoln and buy HD.
3: If your servicing/repairing 10 trucks a day, buy a nice system air pumped, metered guns, etc. ( Lincoln and Graco have really nice ones!!!)

And off you work on your own, and get pissed offf when tools don’t work right and spill oil all over, spend the money for #2!!! American made and built to last!!!

I just hope that stands true in the future!!!!

 

I understand and know where you are coming from. I actually have and used it when I ran a shop, an old heavy duty one, but it is set up for 16 gallon barrels, and I just don't buy it in the barrels just for my own use.

I have no clue how old that one is, iirc It came with the shop when I bought it, so would have probably been old in the 90's. lol
