Re: Axial Play in Water Pump Shaft
Be sure the thrust washer is in place and the freeplay kept to a few thousandths, or this can happen.

Re: Axial Play in Water Pump Shaft
Okay I picked up a B40 fan belt at Napa and it works perfect just the right tightness and still a little adjustment on the alternator arm - thanks
I do see the water pump shaft going in and out as the motor idles so next is the shaft collar, new hoses and clamps and fresh anti freeze. Anything else while I have the hood off and the radiator out? |

Well I pulled it apart to day to find the metal retainer seal on the water pump shaft had popped out that is why I had so much end play. I pounded it back in but I will also install the collar as well. I thought I saw the recommended spacing some place here but can't find it - was it .006 of end play in the shaft once collar is installed? Funny thing someone mounted a collar on the other side that seem to do nothing. |

And, I've seen guys drill and tap the end of the shaft and put a brass screw in to take up the slack. Not sure how long the fix is but brass machine screws are not that costly............... |

What do you think? Should I get the new style leak-less pump? Should I take it off inspect and maybe rebuilt? |

Re: Axial Play in Water Pump Shaft
Use a stethoscope and make sure the noise is coming from the water pump. Can you feel any scraping while turning the fan by hand?
The last generator I did a week ago had a front bearing that felt very smooth and rolled nicely, but when I tested the generator it squealed like a stuck hog. |

Re: Axial Play in Water Pump Shaft
Yes, if I spin the blade with the belt off I hear a clicking and ticking sound. This sound is very pronounced with fan belt on and engine running.

Re: Axial Play in Water Pump Shaft
Okay got my new fan blade today and I also ordered a new leakless packing nut because the rubber in my old one looked a little beat up. Question is - the old packing nut is steel and smaller on the OD and the rubber inside goes the whole length of the nut. The new one is I guess zinc looks like aluminum to me and the rubber seal is just in the top part of the nut, is this the way the new ones are? How tight do you crank down on the packing nut?

I found a company that makes a split 3/8 collar! The advantage is not having to take a bunch of things apart to put on the collar on. I also added a nylon washer so that the split collar installed did not rub against metal and adjusted the tolerance with a gauge! All is now well! |

Re: Axial Play in Water Pump Shaft
If your car is not show standard and just a happy driver there is a very quick simple fix for end float problems . My 30 CCPU suffered a heavy leak which was caused by very excessive fore and aft shaft shunting ,I would guess about 1/2" . I fitted a small stainless hose clip around the shaft allowing about 1/16" end float . Choose a clip which has a smooth section where the clamping screw section is to avoid wear where the clip contacts the packing nut . This contact area in practise is lubricated by a little waterpump grease which exudes from the shaft .This cured my leak, it does have a slight drip now and again but now I dont have to top up my rad after every trip . This fix has been on my truck for over 1000 miles and there is no discernable wear on the packing nut . The setup does not look unsightly as the clip is small I will try to get my son to post a pic . This saves a whole bunch of labour pulling apart etc etc and gets the same result .(and cheaper!!!)
John in same place, weather was cancelled today. |

Re: Axial Play in Water Pump Shaft
I know tis is an old thread ;
I welded up the end of the shaft. Don't know if this is a correct repair, but it works for me. |

Re: Axial Play in Water Pump Shaft
3.6 Welding the end of the shaft is relying on principles that the original pump used when first designed. I have had luck with making a Delrin wear tip for the end of the shaft and so far works very well. I like the original W/Pump and wonder why so many feel the need to go to the super pumps that can't be fixed easily, Kind of like which electronic ignition is the best.

Re: Axial Play in Water Pump Shaft
If you don't want to take the pump apart a shaft collar could be installed behind the fan . The fan would hide the collar and the collar is cheap . Longer shafts with pinned impeller is available , thats what I usually do .

Re: Axial Play in Water Pump Shaft
I'd like to "join" this conversation ...... I have a rebuilt standard pump and a newer metal (maybe aluminum?) 2 blade fan. There's about and 3/4" of lateral play (front to back) when the engine is running. When the engine is not running, I cannot make the shaft move at all.There's no leaking water. The engine keeps cool on longer drives and rarely gets over 135 degrees .....a newer radiator helps this, I'm sure.
The Question: Do I need to worry about this ???? Many thanks in advance for your thoughts... IndyA.. |

Re: Axial Play in Water Pump Shaft
Sorry this response took so long! I got on ebay, and searched on "Steel 3/8 collar" A bunch popped up off the search and I ordered several. Ya gotta do a little hunting to find a split sleeve! It really works great!
