Bien explicado 🎉

It was my job to maintain these . 3900. 5900 and the 7900 hydraulics. Best advice i can give. Dont use oil on leather packings. Rub them with red rubber grease. Soft and sticky grease. Coat them well. And pak your goodies. Alwas locktite on the piston ball valve threads. And send it. My pumps i serviced did up to 10 000 liters of heavy based road marking pain.

let me guess.. epoxy paint?

that moment @42 was all I needed to see. The ball bearing and the two other related parts fell out when I was cleaning and I was not sure what the reassembly order was. Thanks. I subscribed.

Hola una pregunta cada cuántas horas laborables se tiene que Aser cambios de sellos al pistón de pintura

Great video straight to the point. I have a question im working on a graco text spray mark v and seems there is excessive leaking coming from the bottom coming out of the foot valve but the packings aren’t torn and all of rings are intact and the piston rod is in good shape. Any idea why that is ? Could the packings just be worn or any ideas ?

With upper and lower packings , paint does the lubricating for bottom packing and throat oil lubes top packing. Is this correct?

Gracias buen video ,pude hacerlo bien 👍 🇭🇳💪

Hello, great video. Do you know if I can replace my linelazer 3900 pump with a 5900 pump? Is the repair kit for both equipment the same? Thank you.

Hi Colton, My name is Joe and I live in Washington state, and was wondering what a good price is when charging by the linear foot? I’m new to the industry and want some feedback from someone with experience.
