Re: [Chrysler300] 300F Water Pump

["Don Verity" <d.verity@xxxxxxx>]

Ray and All,
The pulley on a 413 is stamped steel that bolts to the hub of the balancer, there is no rubber joint to slip. The outer ring is the only thing that has rubber between it and the hub. How else would you remove the damper from the crank? If it was rubber mounted, it would pull off before the hub moved.

The water pump on a big block is bolted to a housing, NOT the front cover. I have never seen a pump get so bad that it even came close to the housing. 

Gary,
 What do you do about impellers? You usually have to break them to get the shaft out. I would be interested in seeing your procedure for this, as these things get pretty frozen with age. I do have a 20 ton press. 

300ly,
Don

  I haven't seen anyone mentioning the other more likely reason the pulleys were not alined. That could be that the rubber mounted pulley sheeve on the Harmonic Balancer has moved forward some. You might want to check that.

  And, you always want to check the front cover. I have seen several that were eaten out from the impeller blades going deeper and deeper as the wear increased.
  When a new pump is installed, there will be too much clearance behind the blades and not enough water will be pumped.

  A/C units do have (6) six vein impellers and the non-A/C had (8) eight. I
  was told they turn the a/c pump at higher rpm's. That would mean the pulley
  diameters are different for a/c.
  All the more reason to use roller bearings.
  Maybe the differences could be a good tech article on the club site. I could
  get photos of the 6 & 8 impellers.

  Thank you,
  Gary, the parts doc
