I'm having a problem getting my water pump bolt holes to align in order to get all three bolts to engage the block. I have succeeded in getting only one of the three to thread. I experience in dong these w/p's on three 240s and an earlier w/p on this 760. All use the same w/p. I only use Volvo OEM. None have leaked after installation. For pressing the w/p upward, I'm using a ratchet tie down supported from above by a 4x4 and other sturdy lumber supports to gain a vertical lift that mashes the mushroom seal.
As I inspect my progress with a straight pic and mirror, it seems that the ornery bolt holes are not only vertically challenged but there is a very slight w/p rotation yet needed. Consequently, I set up the tie down to have the ratchet on the side with the one bolt giving the greatest problem. This I hoped would provide greater tension, encouraging a little rotation if any. Progress was made but not enough.
I have given some thought to using a bottle jack but not sure if this can be done safely or if it can effectively engage a bottom surface on the w/p.
I have compared the mashed mushroom seal thickness to that of a 240 in my driveway and think that I am mashing well. I even mounted the w/p up with no seals/gaskets and could see that the bolts will engage the block. Gasket and seal surfaces are all clean and smooth.
I'm now considering using a round file to slightly elongate the bolt holes.
So, have any of you had a similar problem? Even filed the holes?
Thanks in advance, For the fun of Volvos,
Mike
