I have a 440i I bought around 2006... I've used it very little and was getting ready to use it recently. As it starts to build pressure, and is almost ready to stop, it starts leaking air. I think it's coming from the prime/spray valve, but not sure. Is there any way to tell if it is the piston packing or the valve?
Hey brian I learned alot from your video thank you for sharing this also I wanted to ask I was given two of these pumps and one I managed to get working again how ever the second one the piston rod has slight pitting and a small factory bump or very small would it be one to reuse this pump gave up the ghost and the previous owner let the paint sit in it for a very long time
Its extrmeley ez to do this. Its one of those things that if you are even somewhat inclined mechanically go ahead and take care of yourself. But if your just one of those guys forwhatecer reason then yea take it in. But its similar to replacing brake pads on a vehicle. Its not hard, parts arent expensive and imo you shoupd understand how your equipment works and be able to diagnose and fix them for the most part if you have the time. Repacking a titan if you have the parts doesnt take more than 15mins.
Hey Brian, my 440i always runs, it never shuts off. Does that mean it isn't building pressure? I just finished repacking it and it still just constantly runs. any other ideas on how to fix it?
Unplug the wires from the motor to the computer board and replace the fuse. Turn the machine on. The motor will not turn, but see what happens to the fuse. If the fuse does not blow, then you have a motor problem. If you have an impact, you will need a new motor. If the machine is older than the Impact series, pull the brushes out of the motor and see what their condition is.
@@miguelpaintingmiguelescoba8072 the Impact series does not have brushes. Some of the old units do. If there is 3 wires attached to the motor, red, black and white, then it is brushless
It can be difficult if it has not been removed in a long time. The easiest way to rem ok very it is pushing on the seat from the bottom or inlet side. DO NOT push in the ball itself. When you flip it over, you will see a small ring that is slightly smaller than the inlet hole. Take a large punch or flat head screw driver and place it on the smaller ring. It should not touch the ball. Tap the punch with a hammer to push the seat, cage and ball out.
@@Brian_the_repair_guy Thanks Brian, now I just have to figure it out how to remove the hose adapter which is on the other end. It looks impossible to remove this metal ring
@@Brian_the_repair_guy hi again Brian. On my 740i low boy are coming the two white power wires from the back side of the pump (control assembly) would you please lmk which one is the positive and negative? There is one on the upper section and the other on the lower section. I’ll appreciate your advice. Thanks
440 only has oil for the piston. No oil anywhere else. The oil is either over full or the reservoir is cracked. Drain the reservoir and fill directly at the piston.
@@Brian_the_repair_guy thanks, mines a 440 impact so can't oil it at the piston, it's just the top bit where you have to unscrew the red cap n pour in the top
@@fletcher-nf4pn you can oil it at the piston. Remove the 4 screws on the black cover to get access. The impact series will eventually leak from the reservoir. Also, the machine does not need to be oiled frequently. 2 or 3 pushes every few months. If you do it more than that, the oil cup over flows. The cup holds about 6 drops total.
No need to replace a perfectly good piston. Replacing this piston would have been dishonest at best and nothing more than a money grab. I don't work that way.
@@Brian_the_repair_guy I realize that Brian .I appreciate all you have posted,I merely stated there are no videos of any human replacing a ball, cage and seat of an airless that I can find online. thank you for all you do sir!
