Default Build A Lo-Buck Gear Lube Pump:

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:

Very good idea - and well-made too!!! I saw CarCraft do something similar to pressure oil an engine before start up (can't recall why they didn't do it the regular way..). As for the oil pump drive shaft - you can usually just grind a rod end to fit (either a blade or hex end).

Thanks for posting!!

sweet. I modify SBC pumps for collecting veggy oil- very durable pumps, and i get them free from an engine rebuilder.

Wish this had been posted a few hours earlier yesterday, or prior to adding 5gallons of hydraulic fluid to my tractor. Sure would have cut down on the mess I made.

Nice work! Gonna have to make one that will work on a five gallon bucket.

I managed to find the lid to the bucket. I also eliminated the pickup hose and used a piece of 1/2" aluminum hard line with an A.N. fitting on the end. I used a grommet where the line passes through the lid:



I also added a filler port so I can pour in the gear lube when it runs dry. I used a metal snap in cap that I bought at Lowes:



Finally, I bent up a piece of 3/8" hard line into a "J", so I can hook it into whatever I am filling. I also added another hole with a grommet so I can insert the filler hose when not in use:

The pump is off any Ford 289-302-351W-351C- or 5.0 from '63 to '97.

Why not just buy a pump lid for a 5 gallon pail? We've had one for years, always works great, no mess and when the pail is empty just pop it on a new pail. Seems like overkill for something so simple??

I ran into the same problem, and here is my solution, though I do have to paint it blue as to not be mistaken for a real fire extinguisher, along with big letters that say lube. Just dump the necessary amount of lube in, pressurize and slide under the car, and let it rip.

Awesome project, drive em. I needed this the other day when putting my diff back together. Next time I'm at Pull-a-Part, I'll be looking for one of those ford pumps. I checked out a Chevy SBC pump today at Summit and they're not as easy to adapt to as the Fords.

Anyone know what thread is on top of the 1 gal jugs of gear lube or ATF? I was thinking it might be possible to piggyback on there somehow.
