Anyone notice blue grease leaking on the bottom of the pump shaft-the part that makes contact with the brake fluid? Is that normal?

I had some on mine; I think it's lubricating grease from inside the pump. It was not caused by brake fluid as I had never used mine before (noticed it right away). I just wiped it off carefully and didn't have a problem.

I haven't noticed it on mine; there's a possibility some brake fluid splashed up on the pump. Brake fluid is an excellent solvent, so if that happened, there's your problem. Also, it's not outside the realm of possibility the company put a little too much grease on your pump when they were making it.

I did so with mine and it is running like new. Do not wait to long. The grease inside turns to liquid and then just flows out of the machine with no warning. Repacked it and it is quiet. There is a video on the internet on how to do the repacking.

It looks like it was. 5-7 pumps should be fine if you need to add some grease at a later date.

Hi Mike, Great Question - I checked. The grease nipple is inserted into the top of the shaft and hole for the grease extends past the top bearing and is cross drilled below the top bearing. The grease fills the cavity between the upper and lower bearing. The lower bearing has no seal on the top side thus it would be lubricated and the grease would also help to keep the water and dirt out. The top bearing has seals top and bottom. I hope this helps.

if this is like the 1 liter one I have, there should be a little insignia of an oil can right in front of the trigger on the top right before the brass rod that goes down into the cup. From what I have gathered, it is not oil that is needed but every now and then add a little petroleum jelly or other water NON-soluable grease just to keep the o-ring pliable...if it dries out, pump won't work...go to Solo site, this explanation should be there

I do not believe this system would work with oil!!! The pump and seals are designed to work with a heavy grease. I believe the oil would run out and spray everywhere. I don't have a solution to your problem at this time. It is very unusual for something that requires oil to have grease fittings. I would recommend that you try to find some old instructions for your machine and see if it had a different lubrication system or used a very light grease. This gun will pump almost any type or grade of grease, but I believe oil is just too thin!!!

I use brake cleaner in mine, there is slight leakage for me, try a different nozzle.

Mine doesn't do that, and I'm not a mechanic. Lubrication sounds reasonable, but I don't know. Sorry.

I have this pump and have had this problem periodically. There are some moving parts that are lubricated at the factory. Some of that lubricant is washed away over time (especially if you have flushed anything soapy). If the pump is stiff (and maybe squeaking), then your piston o-ring needs to be lubricated with petroleum jelly. Once you do that, it will be good as new. Do a Google search for your manual for more detailed instructions.

Shouldn't be a problem it is a grease about the consistency of wheel bearing grease or Vaseline.

I definitely think you should repack the bearing... I was able to repack it in just a few minutes. Just be careful when removing them. You don't want to damage them. I believe you would have to pull the shaft if you have to replace them. Make sure you use high quality grease that can withstand high temps.

If you are referring to the pump lubrication i would say no. You need a hydraulic fluid, like Wagner's Hydraulic Fluid. Or Graco's Pump armor both are pretty good

While cleaning, you may have inadvertently lost the very tiny white plastic bead that sits loose inside the pump assembly at the bottom of the spring piece. Same thing happened to both my units. So I used a round pinhead from a decorative hatpin. Just pulled it loose from the pin and dropped it into the bottom of pump shaft and all worked again. The bead prevents the pump from pushing air back into the soap reservoir instead of out the dispensing tip.

No it will be ok . I used my pump for dextron 6. Solvents like alcohol acetone and brake cleaner will in time eat at the seals inside. Very good tool very happy with it .,...

The reference to oil is sort of misleading. The "O" ring in the piston pump needs to be protected from drying out, specially if it is stored and not used. They really should have labeled it Grease because it helps keep the piston plunger O ring soft and supple to make a tight seal in the piston tube. The pump actually pumps air into the container to pressurize the tank containing your selected chemical mixture. Since the "O" ring is not lubricated by any fluid it can dry out and not make a proper seal. If you google "solo handheld sprayer lubrication" there is a link to a PDF from forestry-suppliers on the 400 series sprayers that says "Lubricate O-ring in pressure relief valve with non-water soluble grease on a regular basis. Petroleum Jelly works fine! On the Solousa.com site under support, handheld sprayers, service & repair there is more info on the care and maintenance of these sprayers along with instructions. But they really should have labeled it GREASE and Not OIL!

When I did mine I also did the oil pump gasket and seal. It is also a good time to get a good look at the camshaft seal and front crank shaft seal. Mine were dry so I left the alone. They can be troublesome to replace. I found a lot of help here http://www.toyotanation.com/

I just put a couple of wraps of Teflon tape on the threads and it never leaked a drop. Just be sure to stay back two threads from the beginning so none of tape gets into the brake line system.
