Removing timing front cover

[friedy]

As the cover wasn't coming off no matter how much leverage I did, I then tried a slide hammer fixed on the pulley flange, again no movement in waterpump it just started to move the pulley flange. So then I decided to carry on and remove the flange from the shaft. I removed the retaining clip, then with help, had levers under each side of cover and with a mallet knocked the shaft down, this is then obviously what caused the bearing assy to come out of the cover. Now I have everything off I can see there is no way the pump would have come out of the back plate conventionally, its so corroded up. Had to press out on fly press.

The aluminium 'doughnut' with the two O-rings in the waterpump should never have any sealant goo on it. the proper procedure would be just to oil the O-rings (or maybe use thin grease) before fitting it into the front cover. The rubber O-ring does the sealing!

I think I'd be inclined to use some copper grease there, though I would check to see about any copper-aluminium reaction first. I've only used oil or thin grease on previous replacement of water-pumps and I've done many.


The same advice applies during fitting of the cartridge water-pumps in the 'Burton' or other front conversions.


My normal way of getting the front cover off was to use a two long strips of wood with rectangular cross-section (says 2"x1" but may need a smaller one to fit in). slide them down inside the timing case from the top, then twist them both so that they apply a fairly even outward force to the front cover.
