PB Blaster won't do anything; the parts are already well oiled.It is stuck in there. I suppose it is nice to hear that they should just come out after removing the bolts but mine is not cooperating. Bit tried tapping on it and soaking with PB Blaster to no avail.
Well, I'm not advising you to beat it to death! My point is that these parts are well oiled, and generally just slide apart. It isn't a press fit, there are no hidden setscrews, etc. So I believe the gasket is all that's holding it.I think this motor is on its first rebuild but who knows about the water pump. I tried a chisel and hammer but it did nothing. Maybe I should hit it harder.
Do you need 105 cores?Yes, I rebuild ORIGINAL 750, 750-101, 101 and 105 water pumps. However, other than the 750 or 750-101 pump, or the 101 or 105 pump for concourse use, this is NOT money wisely spent. The good aftermarket 101-1600 and 105 pumps are less costly than a rebuild. As the aftermarket castings differ from originals, for concourse, a rebuild of a good original 101-105 punp is worthwhile.
The gasket or sealer did not appear to be the adhesive type. I fit a metal putty knife between the gear drive and the gear housing. The brass tach gear is a very tight fit. It did not appear to have any corrosion, it was just real **** tight! The vice grips marked up the tach flange a bit, but ill feather it with a table grinder to remove the marks.Trying the method suggested by jay, will report back soon.
