Profyrfyter Posted October 23, 2008 Share Posted October 23, 2008 Hello all,I'm trying to remove my water pump because I have to replace the rear most packing nut. I've removed the radiator (which by the way both bottom studs have the thread completely rusted away) and the fan. I have been trying to follow the mechanics instruction manual but I am at a loss right now. Can anyone tell me what I need to do to get to the water pump? The pictures below are of as far as I could get myself.Thanks,DaveDoes this pulley have to come off? The four rivets on it are loose so I'd like to try to repair it while it's exposed. There appears to be some type of pin through the middle of the nut(?) Link to comment Share on other sites More sharing options...

Profyrfyter Posted October 23, 2008 Author Share Posted October 23, 2008 If I remove the entire unit then disassemble it then I won't have to mess with the distributor right?Thanks for the help!Dave Link to comment Share on other sites More sharing options...
platt-deutsch Posted October 23, 2008 Share Posted October 23, 2008 Distributor is only 4 bolts.. Link to comment Share on other sites More sharing options...
jan arnett (2) Posted October 24, 2008 Share Posted October 24, 2008 If you leave the distributor in place, don't turn over the engine and mark the location of the shaft and drive gear you will not have to retime it.Jan Link to comment Share on other sites More sharing options...
Profyrfyter Posted October 24, 2008 Author Share Posted October 24, 2008 Ok, so if I leave the distributor in place I just have to make sure I don't turn the engine over? I would rather do that as it's just one less thing to mess with. Now removeing the gear shaft for thew ater pump isn't going to mess with the starter chain is it?

Profyrfyter Posted October 25, 2008 Author Share Posted October 25, 2008 How do I get the nut off of the end of the shaft that holds the fan pulley on? I've driven the pinout but I cannot get the nut off. Is it held in place with a woodruff key and simply slides off the end of the shaft once the pin is removed or is it threaded? I'm stuck....... I really need to get the fan pulley off because the four rivens are loose so I need to repair them and since I have to work on the water pump this is a good time to do it.Thank you!Dave Link to comment Share on other sites More sharing options...
platt-deutsch Posted October 25, 2008 Share Posted October 25, 2008 There is no nut.. it just slides off.. Link to comment Share on other sites More sharing options...
Profyrfyter Posted October 25, 2008 Author Share Posted October 25, 2008 Well I must admit I'm a little embarrassed! I was trying so hard to unscrew it!! haha Thanks for setting me straight!DaveUpdate: I was able to remove the pulley and the cover plate. I have to borrow a gear puller now before I can remove the gear and continue. I guess it's enough for one night Link to comment Share on other sites More sharing options...
Profyrfyter Posted October 28, 2008 Author Share Posted October 28, 2008 Well, I'm to the point now where I'm going to just remove the water pump and drive set as a whole then disassemble them. The shaft is worn at the packing nut, which I was afraid of. Now I'm delayed further since I'll have to order that part now. Is there anything else I should consider ordering at this point? Do the impellers go bad? I already have radiator hoses and packing material on the way. I have a roll of cork gasket material (1/16" thick), it should be ok to use for the components shouldn't it? I would rather just make new gaskets, but if the paper ones are the best way to go I'll get a set of those also.Thanks everyone for all your input!Dave Link to comment Share on other sites More sharing options...
