Re: Volvo Penta Raw Water Pump
That is the pump that Volvo says is not repairable.
That being said....
I have the same issue. I have read that it can be dis-assembled, and the internal "oil seal" and bearing can be replaced.
I have yet to find a post w/ the actual part numbers for this seal and bearing, as Volvo does not supply them, and they have to be cross-referenced to another bearing/seal supplier.
I highly suspect that only filling it w/ silicone will only mask the bad bearing or "seal". The weap hole is there so you know the seal and bearing have lost their integrity, water is getting by, and coming out of the housing itself.
It is ridiculous that these don't have a readily-available rebuild kit.
I was going to take mine off and do a home-rebuild thread, but mine barely drips, and I might just wait until the season is over, as school starts next week, and I will probably only be out a few more times.
There are threads that can be searched that state people have replaced the seal (I suspect it's an o-ring), but they have not mentioned a part number or where they have obtained them.
This is kind of along the lines as the SX drive trim cylinders....you can't buy a $10 wiper seal to fix a leak, but you can buy a whole new ram for well over $400.....
If you are slinging water all over, then you are also sucking in air, and your temps are probably too high to run without seriously damaging your engine.
If you can get the pump out and completely disassembled, there will be a manufacturer's part number stamped on the side of the bearing. With that, and a picture and measured dimensions of the seal, maybe we can come up w/ some viable parts for a rebuild kit.
If you can get the numbers, I'll try and do the cross-reference legwork for new parts, but you'll probably have to get the bearing pressed off and then a new one pressed on.
But you're talking maybe $30 to $50 instead of $300+.......
Let us know what you find out.
