I can't believe I went this long without building this project. I do alot of rear end work on my own cars as well as customers cars, and it is always a pain in the A$$ to get gear lube back in rear ends and trannys. I have used the store bought pumps, funnels etc. and I always seem to make a mess. I built this pump with parts and pieces that I had on hand in my shop, and I am sure that most of you all have everything to build one as well. Follow along:

I first needed a resevoir of some sort. I could have scratch built one, but I wanted to keep it simple. I settled on a cat litter bucket that was somewhat rectangular in shape with rounded corners. It holds about 3 1/2 gallons:



I next needed a plate to mount a pump to. I used a piece of 6" wide x 1/8" steel plate. I traced the shape of the top of the bucket and cut it out:



I now needed a pump. It didn't take long to figure out that an old engine oil pump would do the trick. Since I have a yard full of vintage Fords, a Ford small block pump was the winner. You can also use any pump you have on hand, but the fact that the Ford uses a bolt on oil pickup tube made things alot easier. You may also choose to use a high volume pump for when you really need to fill that rear end in a hurry:



We now need a couple of plates that the pump will bolt to. I traced both ends of the pump on some 3/16" plate and drilled the holes for the mounting bolts and for the oil inlet and outlet:



You will also need a way to attach the hoses to the inlet and outlet plates. I used a couple of steel A.N. plugs that I could weld to the plates. I drilled through the plugs to make a nice fitting that an A.N. hose would attach to. I used #8 on the inlet, and #6 on the outlet. You could also tap the plates and use pipe fittings:





I next TIG welded the fittings to the plates:



Now, bolt the plates to the pump using gaskets to make sure there are no leaks:



Place the pump on the top plate and weld the pump plates on:







A couple of tabs welded to the top plate will hold it to the bucket:



A couple of 90 degree fittings and some hose finish things up:



The inlet is a #8- 90 degree push loc fitting:



The outlet is a #6-90 degree fitting:



I was going to make a hand crank to actuate the pump, but I tested it with my cordless drill and it worked like a charm. You will need an oil pump drive shaft off the engine your pump came off:





I poured a gallon of gear lube into the bucket, and pumped it out in about 30 seconds. I am going to attach a small screen to the inlet, and add a cover to the open end of the bucket to keep out debris, as well as something to hang the hose on:

you probably can't wait for the next rear end project to come in :-) I used those bottles that have a hose attached and elongated that hose, but even then it's a mess. When I worked as a mechanic we just had a huge barrell of rear gear oil and a hand pump with hose. it worked very well, but we used that on a weekly basis at least.

Great idea :-) funny build, but I'm sure it'll work like a charm.

Did it pump both directions?

Could switch the hoses around on the pump and it would be able to suck. And you could put a funnel in the end of the hose to have a wider mouth to catch the fluid with.

I think when i get back home i will be building myself one of these. Thanks for posting the how to.
