Filling diffs, t-case.

I changed the fluid in my front diff and t-case today, and was reminded how much I hate this shitty pumps that screw onto the qt bottles. Has anyone found a reasonably high quality alternative?

Those janky pumps can't be the only option.

 

The synthetic gear lube jugs I get have the cone shaped tops on them so I just squeeze into the rear and t-case. I use a plunger pump on the front that looks like a grease gun. 15 bucks and works great.

 

1.5 gallon garden sprayer. Lop off the wand. Grab a plastic valve that fits the 1/8" line. Cut the line 12" from the pump, insert the valve, snake the remainder of the line into the diff/tranny.

Pressurize, open valve to flow the lube, close valve when full.

 

Can use a drill to spin an speed sensor valve body. Its from an integra/civic that uses a cable speed odometer meter. The pump circulate ps fluid. I got mines for free and love it. I’ll take a picture later.

 

Why not.

People have been using car engine oil pumps to do exactly the same thing.

 

I had previously used a "grease-gun" type plunger pump like @Fury mentioned, but it bypassed too much internally that it couldn't draw fluid from the bottle, so I had to unscrew the cap and fill the gun each time. Switched to this type instead:

Long hose goes to tranny/diff short hose is my new fluid.

Pressure sprayer should work too. Probably easier to get a hold of.

 

Punch a hole in the bottle near the neck, insert 1/4 tubing to bottom of the bottle and run into diff. Drill a hole in the cap, use air compressor at very low pressure with blow gun to push the fluid up through the hose into the diff.

 

Stick a clear hose into the pointy nozzle on the end of the bottle.

 

Wow, lots of good alternatives! The garden sprayers will flow heavy gear lube?? I would think it was too thick.

 

I could be on crack but I thought I was able to pour the fluid directly into the T-case?

You can pour directly into the rear diff too, if you remove the spare tire. Next time I do the front, I am going to try to fill from the top with a funnel and long piece of clear hose.

 

Maybe I just went straight to the pump out of habit. My first time doing it on a Tacoma.
