Bowl not fitting

« **on:** March 19, 2016, 03:47:04 PM »

So I'm putting the bowl on the housing and it stops before it even hits the gasket. I put dabs of grease on the impeller and shaft to try to find what's making it bottom out but when I put it on and take it off the grease hasn't touched anything. Has anyone seen or heard of this. Do I have to machine something. The old housing was cracked along the bolt holes and now I think I know why. If the bolts were pulling on it the whole time i could see it being to much stress for the housing and pop it breaks. Hope someone can help thanks

Same shaft, same bowl bearings?

Sometimes the bowl seal hydrostatic locks on the shaft. Pull the bowl plug and try again.

Same shaft same bearings.

What plug is in the bowl

I've tried Hella times man and it always stops at the same spot and it sounds like it seats on something but its not on the suction housing.

My bad eck they are new bearings same shaft

I put the bowl on a table and it's tapered in. So the outside has a gap. I wouldn't think that's right but I've been wrong before.

What is tapered?

Pull the oil fill plug like Flusher said.

Did you change the end plug?

Hmmm....

Does the impeller turn stupid easy?

Gt it's a early dominator so there is no oil for the pump right. Thats a question not a statement. Don't know what the end plug is but I would think it's a plug ont he end of the bowl which it doesn't have one but if I'm wrong let me know.

Not super easy. You can feel some resistance

The bowl should be flat right

Perfectly.

Did you pull it apart? And how did you get it off?

Look for cracks around the bearing hole.

You likely have a water lubed bowl.

Did you try thumping it diagonally with a rubber mallet? Not too hard.

Sounds water lubricating.

The face with the 1/2-13 suction bolts and the large inside diameter adjacent to that face are the datums to maintain consentricity of the bowl bushings and the shaft. If that face is no longer flat and perpendicular to the bore, the shaft and impeller will bind.

Without the packings installed, it should turn freely with no sticking spots. Only light drag from the seals.

Also listen while turning it

I pulled it apart for the first time since I've owned it. When I did there was a gap on the outside just like the picture shows. And you can see where the gasket mating surface was and it's before the bolt holes start. Can I machine the bowl flat or will I have clearance issues further back with the impeller or shaft to bowl.

What is facing a bowl. Like flusher said.

That's when you have had way too much to drink, but are still coherent enough to make it to a toilet to puke and make it without getting any on your shoes.

Hahaha. .

Seriously though, that's when someone does exactly what you just asked about. Somethings wonky.

You can take it back about 3/16" before the impeller starts get close. You do lose some thread engagement. I can't make out if you have the deep or shallow flange bowl. As long as you have good thread engagement (1.5 x diameter minimum).

The real issue is bringing that surface back perpendicular to the shaft.

I can't tell what bowl you have from the pictures. It may not be worth trying to save it.
