2N water pump installation clarification

Hello, all.
Haven't been here in a LONG time. That's a good thing...little 2N beauty has been putzing around with no problems. But, now I am replacing a water pump and have a question. I've removed the fan, belt and old water pump. There was no sign of a gasket. The new pump has a face plate already installed with a gasket already behind it. There is a metal disc with a small hold in it still at the block and it seems to have some silicone gasket sealant or some similar material squeezing up from behind and also a little worm of sealant coming out of that small hole. That tells me that the disc needs to be removed. However, because I am rather "klutzy," I don't want to start prying around on this thing. I don't have a picture of the block without a water pump so I can't visualize what it should look like. I watched a youtube of a replacement and the block appeared just to be a hole. Would someone mind giving me a mental picture of this? If I remove the disc, there must be something behind it in order for it to have sealant, right? The second gasket would be coated with sealant and placed on the plate of the new water pump? Anyway, I always appreciate the kind help that I receive here. Life is good when you have a 2N.

From the Master Parts Catalogue:

There should be nothing on the block. The new water pump mounts directly to the block. It sounds like part of an old water pump is still on the block -- does that piece look like the one on the new water pump?

Can you post an image?

Here's a block without a water pump:

I forgot to mention something. At least some new water pumps have thicker metal where the studs pass through. If so, you MAY need longer studs. I was able to obtain mine at O'Reilly Autoparts as they are a common size used for mounting carburetors. They were in stock.

Thanks for the help so far. I'll try to get a picture tomorrow. I have a master parts catalog and a repair manual but they only show the water pump side. Jim WI show what I thought I would find. I don't think I'll need new studs. It's just a matter of making sure that the disc I'm removing should be removed! Thanks for now. Back tomorrow with a picture, I hope.

If you are referring to the disks in (items 6 & 8 in HCooke's photo), they slide onto the water pump mounting studs before the water pump and yes it would be a good idea to remove and re-gasket them.

Here is the disc that has remained on the block after removal of the bad water pump. In looking more closely as I tried to take this picture and feeling behind it, it does seem to "stand alone." I can clearly see the gasket sealer around the edges. Meanwhile, I'll have to see if there is an offset...meaning the disk is out further than the block. If not, why wouldn't I go ahead and put the new pump (which has the plate #6 in the exploded view already in place with gasket #5 sealed. I could just put sealer on the additional
gasket #8 sent with the pump and it would be good to go. If I need to remove that disk, fine...but then it seems the additional gasket #8 sent with the pump is going to create an offset...unless it really compresses. I know that I will need to remove the old gasket sealer that would make a firm seal impossible if not removed. Thanks again for the patience and help.

Totally your call but if it were me, I would remove the plate and re-gasket and seal with Permatex® Form-A-Gasket® No. 1 rather than take a chance that I had disturbed the existing silicone seal.

I do not like silicone. It has very few benefits and a lot of cons.

I'll take your word for it and remove it all and use the Permatex Form-a-gasket. That's why I asked the question...I knew people here would have good advice. Thanks so much.

Success has come to visit here! After taking and posting a picture for the water pump question, I have come to realize what a ditz I really am! Hard to admit, but truth is truth.

The plate from the back of the old pump had remained on the tractor. I couldn't get my head in front of the pump to see too well...didn't take off the radiator, so it's quite a squeeze. All I could see was a disc. But, when I saw the complete picture of what was there, the completion of the task was a snap. All I need to do now is to tighten the generator/belt and see if "it'll fly." Hope so!

It's great to have "consultants" for my tractor work. Consultants can pull down some big bucks, they say. So, thanks for your volunteer efforts.

Glad to hear of your success!
