71 Washer Pump Restoration

[Sheldon S.]

I am trying to take apart my washer pump so I can have it replated. There are two pins that seem to be held on with some sort of solid washer. Can someone decribe how to take apart the componets from the metal backing plate.?
Thanks

Sheldon,
Taking these apart to replate the base is very easy and straightfoward. The only tricky thing is removing (and re-instaling) the coil. I don't know the names of all the parts but I will describe the disassembly. I just did 2 of these so it is fresh in my mind. One thing you must do is to take pictures and make notes so you can put it back together properly. First remove the 2 springs on the right side which will let the upper metal piece come out and, after removing the "e" clip the ratcheting arm can be removed. Next the plastic wheel comes out by pushing the spring away from the post and lifting off. Note carefully how the "shaft" of the piston sits on the ratcheting edge so it can be reassembled the same way. The flexible ratchet stop just screws off. Note: some later model service replacements have this piece staked on. I have not tried to remove one of these. The piston assembly comes off by pushing it to the left and then lifting off the post. The coil is a bit more challenging. From the back side, GENTLY squeeze the 2 posts together just enough to push them through the slots. The cam on the back is removed by prying off the push on fastener. You will probably need to buy a new one which is a common fastener. Any of the permanently fastened posts and rotating assemblies do not need to be removed for replating. To reinstall the coil place a large screw driver between the tangs and twist it to spread them apart untill the coil is tight against the plate. To put the piston back you will have to pull out the flat "shaft" to get it over the post. I hope I have described this well enough for you. Take your time and make good notes and photos and you should have no problems.
