I would like to rebuild PS Pump. Any advice?


















I am keeping the ends and planning to replace hoses only. How do I loosen the end where the nut is too close to the hose?

Those transmission hoses on the bottom pic with the small ferule can be bolted onto a male fitting. you then grip the hose with a pair of pliers and twist it anti clockwise. The hose will unscrew from the nipple.
Re rebuilding the pump,from the pictures it looks good and is typical of these vickers pumps . Just replace all the seals and it will be good to go.

Didn't Chris Johnson talk about feeding rope into the #1 cylinder in one of his postings?

Also,the notch in the damper can be used with a 1/2 drive extension braced against the engine block .

The factory WSM does describe and illustrate this method, but it has its drawbacks.

The one time I did this it resulted in a cracked water manifold. The extension piece is forced against the water manifold to stop rotation. The water manifold cost only $300 to replace at that time. Since the water manifold was badly corroded inside, it wasn't an unnecessary expense so not a lot of heartburn.

However, the next time I removed the pulley (to rebuild the engine) there was no way that I was going to set myself up to have to replace the water manifold again and that's when I employed the "rope down the spark plug hole" method to keep the engine from turning.

If you aren't constantly impressed with your car, then it needs fixing.

Be sure that the vanes are installed with the correct radiused surface outward. Clean the vane bore with 350grit by hand. Rub the sides of the vanes on a flat surface on the 350 grit with lube, kinda polishes them to perfection. You should be able to hear the vanes cliking when you spin the pump by hand. Before the seal install.

How to separate master cylinder from plastic containers?



Booster is out. It needs replacement.



No rust inside the pipes, just outside. Do I still need to replace them?

If they are as good as they look, I see no reason to replace them, just get them gold zinced. Make sure the narrow pipes are plugged at all ends before they go into the plating or they will rust badly inside afterwards. If you don't want to zinc them, clean them thoroughly and use one of the proprietary spray cans of gold zinc coloured kill rust paints and paint them yourself. You can get kill rust primers as well if you want to be thorough.

The reservoirs pull off the master cylinder at the rubber connections.

How many gaskets are there on crankshaft cover? One or two. Does anyone know a part#?



Tom sent me this gasket but it is for something else.

There is no gasket between the engine and the crank cover. Use a joint compound (not RTV!). All that dark goo on the cover is the originally used compound. It can be cleaned off with carb cleaner or something of that type. Tom sells a very good factory joint compound item.

The gasket he sent goes between the water pump and the water manifold.

Those pulleys look pretty crusty. When was the last time this thing ran under its own steam?
