Water pump, strange noises

[CADMAN]

Since coolant flush and change, been getting strange squealing noise from what I suspect is the water pump. Looked up parts/info in service manual and looks like a straight-forward fix.

Question is, has anyone done this repair other than thru dealer or shop? I'm pretty handy with wrenching, just not wit internals of a bike. If it was on a V-6 or V-8 Chevy no problem. Any advice or guidance?

Do you have an FSM?
It details how to install the bearing and seal. I'd listen with a stethoscope and pin point the area. Confirm thats it!

Here is a thread with a link to an R6 pump over all. Take a look and see if you're up for the task. Like throwing CAM bearings in a 350 Chev. No problem right!

Direct - if it works.... Scan for water pump

Thanks for links. Nothing in manual says if bearing is press fit to impeller so I thought I'd check with forum experts. :thumbup:

I don't think it is. It may be a rust fit tho!

Seems to me that bearing are shot... But before you did some flushing is the noise there or just occurred after the flushing?

I've never had to change the seals/bearing on the FZ but have on other bikes.

Their NOT a press fit. There's no reason to have them pressed in. Thier pretty small and carry little load. Gently tap them out as directed and install like any other bearing.

I would definitly replace the mechanical seal while there as that's usually what fails/leaks.

The parts are cheap enough and I'd prefer to do it myself as I don't need a newbee at the shop screwing it up.

As you noted, there's not much to it. If your comfy wrenching on a V6 or V8 you should be fine... Bearings and seals do thing same things on bikes/car's, etc.. :thumbup:

Noises started after flush/fill. Flushed twice with deionized water, brought to op temp then drained and filled with Yamaha coolant.

...strange squealing noise from water pump...

UPDATE - REPAIRED

My experience:

Starting here

Draining system, thought this was a cool pic, also removed inlet and outlet hoses.

Outer cover removed, nothing strange.

Pump removed, tight fit on that mounting O-ring. Used compressed air between inner half and engine to loosen then pulled right out.

Inner half drive side view.

Disassembly; oil seal, pump seal, oil O-ring & bearing, housing gasket & impeller with rubber damper & holder installed, circ clip.

Seal removed, noticed rust formation.

Cleaned surfaces with degreaser and Fast Orange hand cleaner.

Assembled per Service Manual. Manual error at step 3, fails to mention rubber damper & holder are one piece. Refilled system, no leaks, started, up to temp, topped off and took it for a ride. All done.

Looks like (as you noted) in pic 666(that's kinda wierd!) coolant got past the seal over time and to the bearing. The rest of the unit looks reall, really clean..

Just curious, how did the bearing feel, water in it, seal appeared dried up at all?


Great write up BTW, (saving it for later posting for other folks...)

...pic 666[/B](that's kinda wierd!) coolant got past the seal over time and to the bearing...

That 666 was weird, didn't notice the numbers when posting. Was trying for pics between text, not too experienced at posting pics, didn't want thumbnails.

Checked that vs new bearing, no noticeable difference, no water/rust in bearing. I think water got between seal and housing but seal held around shaft.

Took longer ride today, squeal still present though not as loud, and it does run 5-7 degrees cooler. So must not be water pump, still searching for solution to strange noise.

If you can upload a video of the noise, trying to zoom in to the origin, may help locate the problem..

I'm assuming its RPM based?

 

[Motogiro]

Great job! Thank you for posting this! Pics now display..

 

[CADMAN]

Yep it is RPM related. Noticed more on throttle and at off load.

 

[TownsendsFJR1300]

If you can post a video of the engine running, so we can hear the noise, would be a big help.

Taking a stethoscope or a screwdriver to the area touching the engine and the handle to your ear, (you've likely already done this on other machines) may help you narrow down the area.

How many miles on the engine?

Any recent work (besides the pump re-build(ie APE CCT, etc) done?


I have to ask, you are using some sort of coolant, not straight water correct? The mechanical seal and the "whitish ceramic (I think its ceramic) round washer looking thing" on the back side of the impellor) does need some lubricant between them. Being the noise started at the same time of the inital coolant change there's really no other moving parts with the water flowing (its not the fan kicking on and it does spin freely?).

72XX+ miles

Nothing other than oil change.

Initial coolant change (with distilled water flush) was Yamaha coolant when noise was noticed, so flushed again and refilled with Prestone 50/50. A little less noise but still odd sound that was not there when purchased with 4200 miles.

 

[TownsendsFJR1300]

Is the noise happening when in GEAR/Moving?

You later mentioned "on throttle and at off load". I'm not sure if that means all the time??


I ask as even thou the mileage is low, the DRIVE chain, if overtightened and if not lubed enough will whine.

On the FZ, there should be approx 2" of total up and down play (checked on the centerstand), see below pic. It is imperative to make sure the chain tension is correct, (even if it isn't the current issue-it will be later of too tight).

Its possible its just another issue that occurred around the same time..

please update the photos, nothing is visible... I'm planing to change the water pump bearing, too. thanks

I'm sure someone has a maintenance book on digits w/o reviving a 366 day old thread.

Replaced url w 600riders. Looks to work!

[MENTION=20175]CADMAN[/MENTION] ^^ + 5 for great pictures too! :thumbup:

Did you ever isolate/solve the noise issue?

Also, the weep hole, do you recall if this (see pic) allows coolant to leak to the ground? Surely it goes to the outside and not internal to the engine when installed. Hint - I've never looked up to see it once installed.

Tks!
