806 MCV

caterpillar guy · Mar 9, 2021

Got the MCV off the 806 it blew one of the gaskets out. Wanting to get the springs and pieces out that are held in with pins. How do I get them back in after letting them loose? Don't want to remove them if they will not be able to be put back in. I want to get it cleaned out before reassembly.

Long skinny drift punch . I usually put the valve body in a vice as i have this thing about crawling around a 40x72 shop looking for springs and valve on the floor , Just sayen . .

What is the little valve under the brake fitting on the top rear corner look like? I think it is lost or mia before I got this apart this time. I have the spring so am guessing the valve is missing. According to the service book it is a check valve for the brake line. There are no pictures of it in the book though to see what it is.
A punch will let me hold the springs on the pieces that are pined in. They are not to stiff then I take it. Like the other springs on the vlaves I have to put back in and start a plug behind.
