This frees you to put the good hose back on. Simply remove the collar and pull the broken hose off of the barb. Do this several places until the collar splits in half. To remove the factory hose, simply insert a small flathead screwdriver into the collar between the collar and the hose. Or, cut the end of the hose flush, and simply use a small hose clamp to secure the hose to the barb. If your pump had its hose broken off, simply purchase some good automotive hose that can handle up to 100 PSI (Try fuel injection line).

If you are like me and maintain your equipment, a sub $5 flavor injector from Wal-Mart packed with good quality synthetic grease (I use Mobile-1 general purpose full synthetic red grease, it has served me very well) will allow you to inject grease into areas where it would be impossible any other way. If you do not have a flavor injector, you can use a Q-tip, but it will not do as good of a job.

Once you get the crankshaft out, you are free to clean and lubricate the crankcase. I grease all of my angle grinders when I buy them, and they last a long time. The greasing of many of your tools will make them last nearly forever, especially right after you buy them. I accomplished this by putting 2 flathead screwdrivers under the large driven gear, while I pried on the crankshaft with another screwdriver, until the crankshaft popped out.Īs I nearly find with everything I take apart, an appalling lack of lubrication for the bushings for the crankshaft. I had to pull the crankshaft out, then slide the gear out. Unfortunately, this design would not allow me to simply pop the large driven gear off. Right away I could tell this was a good pump. Most inexpensive pumps only have 2, and some don't even have the cooling fins on the cylinder head. This particular pump has 3 cylinder head screws. This is because you forced the commutator to grind the dust away from the brushes and created a new electrical connection. Then, plug it in and it will suddenly work. The motor has enough torque to tear your finger open, so make sure it in unplugged. Sounds complicated and hard to fix, but it is as easy as taking it apart and turning the gears by hand while the unit is unplugged. It would have worn itself just by running for a few seconds.ĩ times out of 10, the reason why it no longer works is because of dust and debris between the brushes and the commutator of the motor. I didn't even try to turn it on in that condition. There was so much dust it had clumped up into dust chunks the size of popcorn. All of the pictures I took were after I spent several minutes blowing out the caked-on dust inside and outside of the pump.
