The bolts should be fine, so long as you used distilled water with the coolant.

It's the minerals in regular tap water that gunks up the insides of a cooling system the most.

Success!
Let the blue RTV gasket sealer cure up over night and filled her up with water and topped off the oil this AM. Not a camr out of anywhere and it feels great. The old original 85' impeller was totally siezed. I'll attach some pics later. Total work tine was like an hour if you don't count the times suggested for letting the RTV setting up before torquing and the curing. Didn't use new o rings cause I didn't have them. What can you do... Work fine and will be sure to have them next time I go in which hopefully will be a while.

Good to hear you got it to work.

But next time, for when ain't nobody got time fo dat, use The Right Stuff. Worked well on my water/oil pump

so everything holding up and there definitely wasnt too much rtv gasket sealer used but my oil pressure light is coming on. I took a look at the oil level window and it's staying around halway while it's running which tells me it aint pumping.

What's up?
is it possible the switch is faulty?
If so I've got my old one on the old body.
why is oil not pumping?

on the 85' k100 pump there's only one wire and sensor and the other whole had a plug. On the 93 k1100 pump I put on there are two sensors and the one I don't have a lead to (which I don't know what it does) is dripping once every three seconds but only when the bike is running. As if it's building pressure...

I'm stumped. Was just gonna pop the old sensor in and plug the other with the plug from the old pump.
what's up with the sensor that I do have a link for that senses oil pressure.
Is it responsible for switching on the pumping or just a sensor?

The pump's all mechanical. Not sure why it wouldn't be pumping. I mean it should be...it's a pretty simple system

The sensor that you don't have a lead to would be for a temperature gauge which the donor LT had. My bike has a VDO temp gauge in the fairing (thanks Drake)

Laitch · « **Reply #31 on:** October 10, 2015, 10:34:13 AM »

Like F14 wrote, your combination pump is mechanical—pumping when the engine is running—and your description of the K1100 pump indicates that it probably had a temperature switch installed then wired to a gauge, that’s why there are two wires instead of just the single wire from the oil pressure switch. What kind of liquid is leaking from the unidentified switch every three seconds—coolant, oil, or a mixture of both—and from what part of the switch is it leaking? Have you tried loosening the leaking switch then retightening it slightly more?

How much oil is in the bike? If there is sufficient oil in it then the oil pressure indicator problem may be from the switch wiring, or the replacement pump’s oil pressure switch is seized. You could substitute your old pump’s switch for the one that came with the replacement pump to see if that shuts off the light, and you could remove the unidentified switch replacing it with the plug from your other pump to stop the leak—both tactics that you already have suggested.

If the switch and plug substitutions don’t shut off the oil light and wiring is ok, your old oil pressure switch may also be defective, the replacement pump may be defective altogether, or engine bearings may be failing.

Which manual are you using for guidance?

MichaelMandel · « **Reply #32 on:** October 10, 2015, 10:51:37 AM »

Thanks for the response.

The fluid leaking seams to be straight oil.
I would say my primary concern is that the oil level sight shows a half full case when its running which I believe indicates that its not circulating???

Laitch · « **Reply #33 on:** October 10, 2015, 11:02:55 AM »

If you believe the pump is not working then run the engine for a few seconds only to determine results of switch replacements or the engine will fail. How much oil did you put in the engine?

Is oil leaking from the oil pressure switch or from what may be a water temperature gauge? Which manual are you consulting?

Haven't been using a manual much, just the forums directions and pictures since the manual I have is an on computer version of Haynes and using it sucks for both the content and experience of needing to be by the computer.

I think it's leaking from the oil switch and I believe I may have the oil pressure sensor wire on the wrong sensor. I'm about to go out and tinker. One thing I'm confident about, the oil level is about right, 3/4 of way up glass when off, and its at halfway up the glass while running.

MichaelMandel · « **Reply #35 on:** October 10, 2015, 12:10:10 PM »

Since I'm only dripping when its running and there does seem to be a quarter of the sight glass window circulating is it possible the the pressure release valve is malfunctioning?

Laitch · « **Reply #36 on:** October 10, 2015, 12:36:51 PM »

Anything is possible when exchanging used parts with used parts, Michael. Have you reviewed this thread?

MichaelMandel · « **Reply #37 on:** October 10, 2015, 01:19:07 PM »

Think I have read the thread but will read again.

Most of the oil definitely seems to be staying in the case. In my mind possibilities include a faulty pressure relief valve and I didn't RTV the inside of the crescent moon shape just the outside(know what I'm talking about?. Would that effect it oil pumping? I really don't want to pull the pump again when its holding so well and without leaks....
Did put the wire on the right side sensor and the lights off now. Oil doesn't seem to be moving though based on the sight glass.

Laitch · « **Reply #38 on:** October 10, 2015, 01:41:12 PM »

The photos of that thread are what I was wondering if you had viewed and if the site of your pump's leak was the same as the photographed example. It appears as though you're making progress if the oil pressure light is now off when the bike's running. There really should be no leaks from that pump if it's components in good shape and it's sealed properly.

MichaelMandel · « **Reply #39 on:** October 10, 2015, 01:56:26 PM »

I'm now thinking the pressure relief valve is faulty. Would that be responsible for little to no circulation?
... And yes, seemingly the same leak site and switch.

Laitch · « **Reply #40 on:** October 10, 2015, 02:29:51 PM »

A seized-open oil pressure relief valve would impair correct pressure but "little or no pressure" should also trigger the warning light. Did you change the filter and add almost 4qts to the case before the engine was started after you bought it?

It seems like you may need to remove the part to sort this out.

Light is not triggered now but oil is level is not going down when running. Maybe air pressure is building or there's a little oil pressure in there but little circulation.
Yes have been riding and oil and filter has been changed twice and is at right level. Relief valve is what I'm thinking now. Will replace valve with old working one and pop cover back on and test. If not corrected will then remove pump.

Sound about right?

MichaelMandel · « **Reply #42 on:** October 10, 2015, 06:03:50 PM »

Oil light now illuminates before on button is pushed. Turns off when motor runs. Oil level goes down 1/4 to a half length of window sight when motor is turned on(fixed stuck valve by tapping pressure relief valve while running) and all that remains is the slight drip from pressure switch when running. Gonna loosen and re-tighten switch and if the drip doesn't disappear I'll swap it out with the old switch.

Lubrication and cooling check.
Now it's time to move on the getting the rear brake to work. Master cylinder is busted. Bought another one from an 05 k1200 that looked similar.
Anyone know if it'll fit?

One thing I'm confident about, the oil level is about right, 3/4 of way up glass when off, and its at halfway up the glass while running.

The level on a cold engine, on the center stand, should be in the middle of the sight window. When running, on the center stand, the oil level should probably drop below the sight glass. Your oils is a tad too high, but the concern is the lack of drop in level. It might be circulating but not sufficiently. I can't see in the text whether you've changed the oil filter (probably you have). Is it installed properly -- screwed on by hand until the gasket beds then 1/4 turn? Absolutely certain you haven't blocked the relief port with RTV during the pump install?

MichaelMandel · « **Reply #44 on:** October 10, 2015, 06:48:06 PM »

Yes quite certain RTV isn't blocking and filter is definitely installed correctly because I haven't changed it since before pump swap when it was pumping.

I'm thinking the pressure relief valve has opened up a bit but not fully and perhaps should be replaced or have a new spring loaded. Since it has improved after being tappped I'd say it's operating but not at full capacity. I'll continue to ride lightly and tap and if circulation doesn't continue to improve I'll replace valve in replacement pump with the old one and see from there.

How does that sound?

MichaelMandel · « **Reply #45 on:** October 17, 2015, 10:47:34 AM »

Hey Guys.

So... I popped my new pump on and pulled it off last night after a week or two of short 5 mile test rides.
Pump was spinning well and not leaking. When started up oil would sometimes take up into sump and sometimes not. After good few mile warm up oil would not be circulating. Could be in my head and could not but tapping on the Oil Pressure relief seemed to get things flowing at startup but one in full warm ride just sloshed in oil pan. In other words the oil would get taken up, albeit a little slowly, at startup but stop circulating after warming up fully and getting a few good miles in. My thoughts were Oil Pressure relief being a little sticky in the donor pump so I pulled the valve piston from my old one and figured I'd pop it in new one with a new spring and remount?

Any other thoughts before I put it back together? Perhaps a passageway is clogged? anything else you guys think?

Please don't suggest RTV clog as I put the correct amount on and after pulling saw the evidence it has nothing to do with that.

Here's a link to what I believe is Michael's original post outlining the history of his bike's oil circulation problem and his steps to remedy it.

If there are still doubts as to whether the pump is circulating oil or not how about removing the pressure sensor and rigging up a mechanical oil pressure gauge?

I wonder what symptoms develop from a loose oil filter or an oil filter installed with two sealing rings—a new ring inadvertently installed over the old one? An oil filter backing off its mount would probably affect pressure and circulation, wouldn't it?

Circulation was fine before pump change. Filter isn't at fault.
