Having a little problem that needs some help. Got everything apart except I can't get the water pump housing off of the block (and water pump is removed). It is obvious that there are two studs, left and right on the bottom half, and of course I have all of the nuts and washers off but it is not obvious what is keeping it so tightly attached to the block. It seems that it should now separate. I gave it a couple of whacks with a hammer from the head side, but it is not moving and I am afraid of braking the casting. I suppose I could leave it there... It is not absolutely essential that it come off for cleaning but I was hoping to remove it to have the block cleaned and checked. (And decking would be a problem if it were to remain.) Anyone else have this problem? Is one of the water pump studs actually a through stud into the block and it is stuck? The book doesn't help on this point at all.. Jim

Thanks all!! I still don't have it separated, but you have confirmed my suspicions... Jim

Jim,

The 8 o'clock stud is 3/8 x 31/4" long according to the parts manual. I have had mine off and I needed a stud 31/2" long. The stud goes through the water pump housing and into the block but is not threaded as it passes through the housing. In other words when everything is clean the housing will lift right off the long stud. Your housing is just stuck to the block.

Jim,

There is one water pump stud stud that goes all the way through in to the block. It's about 3 1/2" long.

Jim, I"m not at home right now so I can"t look in my parts manual, but If memeory serves me correctly, there are three fasteners that hold it on. I remember having a hard time getting it off and then found something else to remove. I"ll be at home tomorrow so I can give a look at the parts manual and give you a better idea.

In the archives, (HERE) you answered that there were three. If you mean by the third one, that it is one of the water pump studs, okay, but if you mean a third separate stud through the housing, I must be blind. There are of course, three studs holding the water pump to the housing that are spaced 120 degrees. Two of these three cannot possibly go to the block (the upper one is above the block and the lower right one clearly is into a blind hole in the cast housing.) The third is at about 8 oclock and looks like it could go through. There are two more obvious studs holding the housing onto the block (that have nothing to do with the pump) on the lower part of the housing, but I don't see any more fasteners to the block unless, of course, it is that third water pump stud (at 8 oclock going by the water pump)goes all the way through to the block. That is what I am trying to determine. (This is what I think Mike has confirmed below.) My camera will be back home tomorrow (wife's got it with the grandkids), so if we need a picture, I'll provide one later. Jim

Jm, I'm at home now and looked in the parts manaul. If you look at the pump from the front, the stud at the upper left is a 3/8" x 3-1/4 " stud. The one on the upper left is 3/8" x 1- 5/8" and the lower one is 3/16" x 1-3/8". I believe the long one holds the upper generator bracket, I believe. I seem to recall having a tough time getting my water pump off and having to rotate the entire pump around one of the studs to get it off. It's been 5 years ago, but for the life of me I can't remember which one. But I did get it off without damaging anything.

Yep, been there. The lower left stud goes clear through it. I can't remember exactly what I had to do to get it off. I do remember that I had to make a new stud for it.I did it mainly to replace the gasket. I think I drove a screw driver between the piece and the head , working all the way around the gasket a little at a time, once I got the gasket to let go I think I was able to spin the housing on the stud. I wouldn't recomend it if the gasket is good.

Good Luck,

Mike M.

I could not figure out how to get that darn housing off either. I ended-up leaving mine on the block. You can still do everything necessary to rebuild the engine with the housing on. I just treated it like part of the block, once I conceeded and decided to just leave it in place. It won't interfere with your efforts to clean/prep. the block. If it ain't leaking past the gasket, let it be, unless you think you might have loosened it up enough that now you have to remove to regasket.
