620 Water pump

[POP]

Question – What is the purpose of weep hole on bottom of 620’s Water pump?
Replace the impeller and bearings plus seals on the water pump 6 months ago. Now it is leaking again!!!! Thinking of plugging the hole to stop the leak, most likely a bad idea. What do you think?

If you plug the hole then the water goes into the bearing.

Try some bar's leak.

You seal may of cracked when pressing on the impeller ?

I was thinking I put a dab of grease on that seal to impeller surface so it isn't dry upon first start up. Wonder if it could of burned up allready ?

One time i had a tractor that never leaked, ever. That was because they had a piece of thick cork stuffed up in the weep hole.

Well, you're not supposed to do that, so pull the waterpump off and examine the seal. I bet you had it cockeyed and didn't put any pre-lube on it.

The weep hole is a warning that your seal is bad. If you plug it the water will go into your bearing and probably cause more harm than good. What kind of seal did you use in your recent rebuild? Was it unitized or a 2 piece seal and ceramic? Any questiions feel free to email me.
