Fans running a lot??

Sure would like to here from someone who has actually replaced a waterpump on a 1330????

I think you're the pioneer Lew. Hence the morbid curiosity.

Have you dismantled the old pump yet, to inspect for evidence of failure?

Yes, both the impeller and the drive gear are fine. Think we are down to the thermostat.

[Mikey]

It's killing me, did you get it back together, dry and fire it up???

Yes, it's back together, let it sit overnight to see if there were any visible leaks. But I am waiting a bit------ If it leaks like it did before I may break out the sledgehammer------- In 30 minutes are so.

I referred to a"bleeder plug" in an earlier post------ I can't find it anywhere on the parts diagrams. I may pull the pump again and remove it from where I "thought it came from" THe gasket has a 1/2" hole on the upper right for the bleeder hole. It fit in there. ( the #4 in the parts diagram is pointing to the hole)

[bluewoo]

So the bleeder plug was loose?

Thanks for the updates and good luck!

[trikermutha]

What bleeder plug are you referring too?

Does it attach to the bleeder hose nipple?

[Lew L]

No, sure doesn't seem like it. as I said, it doesn't show on any diagram I've seen. That hose nipple attaches to a hose back to the coolant tank. It's one of the 4 hoses that attach to the pump. I'm referring to the small hole in the block and its larger hole in the gasket. The "plug" that I'm speaking of fits nicely into the water pump at that point on the upper right of the main gasket.

As I've started the and it is now leaking from the front upper quadrant of the pump housing( as you are looking at it on the motor)-------- I'll be removing it yet again ( I'm getting far to good at this) I'll leave this mystery "plug" out this time though. You All will get a pix of it . I'll search the motor drawings from cheapcycleparts.com for this mystery part.

[trikermutha]

If its the bleeder fitting the smallest hose fitting on the pump then that goes to the hose to the top of the coolant tank. I dont think there is a plug at all that I can tell.

I have my bike apart and looked into that area a bit ago.

I have to look again and try to see it??

[trikermutha]

All I see is a gasket and a O ring on that pump no plug . Its a One piece gasket that also goes around the bleeder hole.

The O ring looks separate.

The gasket has a round part that seals a small bleeder hole in the block. Its about 1/2 in in diameter and attached to the gasket with the 2 larger rectangular openings. Thats where I thought the mystery plug went. I'll be pulling the pump soonest and get the mystery plug ready for photography.

Triker,
Thanks a lot for hanging in there with me in this " adventure". If I'm the guinea pig on this waterpump thing here is my word of advice------ Don't

Sure like to see a picture but pretty sure none of those are blocked on the gasket. They should all be open to let the coolant pass thru.

Be waiting for that picture.

And now of course I'm having trouble uploading pictures

Had to use another computer. I think it was the size of the file ---- which I shrunk.

[trikermutha]

Is that one of the bolt sleeves?

I dont see anything else that could be it except a bolt sleeve??

I really dont think it goes in the bleeder hole at all.

[trikermutha]

Like to see the pump too. Gasket side.

[trikermutha]

[Lew L]

I'll wiggle the pump out later. It surely isn't a bolt sleeve as it's solid with the washer( magnetic) like end swaged ont to what looks like copper rod.

[trikermutha]

Are you sure it came out of the pump or did you find it laying around?

[Lew L]

Are you sure it came out of the pump or did you find it laying around?

It fell out as I removed the pump, did I see it actually fall out---no as it's awfully tight in there.

[trikermutha]

I looked at several pictures of the pump and see no where that could be on it. Even found a picture of the impeller. I wonder if that was laying in the top of the pump and when you removed it it fell out?

Unless some else chimes in and knows where it goes I see no need to use it on the pump..

[CopperSpyder]

I have no Idea Copper round disk with pin through it, I don't know what the thermostat looks like but maybe part of that. let the guessing game begin.

[trikermutha]

Maybe check with the dealer service dept if they know where that sleeve goes? Can't hurt to ask.

Found these pics on ebay
This link shows #2 flat head screw? https://www.cheapcycleparts.com/oemp...engine-cooling
My guess its a piece of the old thermostat!
