Thank you for all your help, I am going ahead and changing out the belt and tensioner possibly closing the barn door after the horse has left but it may save the pump for now considering there is only 65000 miles on it.
I tried to find another number on the housing but when I tried to clean it off a bit more it froze over with the cold, then ran the engine to warm it up and searched, even used a mirror but nothing. My name should be Simone's list, she was out today and as soon as they say they are resuming production I will  pull the pump and see if the number is under the bracket.
With all your research that affects so many coaches you should be immediately awarded an honorary "Hero  Status" on the forum. 🏆

David,
Another number is there somewhere, I never found mine until I scrubbed it on my shop bench. try some simple green and a small brush. Feel certain its on the bottom flat area same as your other numbers.

Like I just told a person in private email. I did not enjoy suffering the failure on the road, but at the same time sort of glad I did. We are still new to both the RV and FT community, and are planning to be so for the next decade or more. Had this happened later down the road, we would have found out about this pump sourcing issue way to late to have made a difference, and be in much worse shape. I have seen through all this that our brand support network, really did not seem to think this was import. That telling the customer "No longer available " was good enough. Luckily for all of us at least one now does.

 I am glad that my efforts, as well as the support of the community has shown the manufacturing industry, and at least OUR brand, that the demand is still there and needed. As Michelle stated in an earlier approach.....the village came together to make it happen.....all my efforts would not have gone far, without all the owner support. Thank you sir for your personal support and compliment.

Mike,

If it weren't for your efforts, both in collecting information and identifying, then reaching out to, the key players and then communicating the sense of urgency to the membership of Foreforums, and if the forum membership hadn't responded so solidly in its interest and support, it's highly unlikely we would have the good outcome these efforts have produced.

Foretravel would have continued along the "NLA" path, with a serious detriment and possibly black eye to the brand when coaches could no longer be repaired because of the unavailability of such a basic, "out of sight, out of mind" component.  QCC might have scrapped the specs/drawings for these pumps since they were no longer supported and they didn't know about the level of user base still out there.  I feel that it's because of the efforts and communications to the key parties by members of this forum that a potential "hard stop" has been averted.

I have never been so proud of this forum's membership.

Just spoke with Simone, at QCC and they have started the process for making more pumps, they have put out bids for whatever is needed. She has everyone's emails and will respond with pricing and availability as soon as they get the details.
THIS IS GREAT NEWS!

I told her that I could not find the second required number without removing the pump which I would be happy to do if they start making them again. Equally I said that I would be happy to put a deposit down if required.

Great news, I have to agree with Mike, if this hadn't have happened when it did, we may have never been able to influence QCC to ramp up production. I don't know how many emails were sent but it must have been impressive. Thanks to all who responded. What a great community, I'm proud to be a part of it.

David,

Good to hear. When last she and I spoke, other than sending out quotes the final decision of actual production, though positive had not been made.

We sent here a nice gift basket to show our appreciation for all of her help on this situation. To be delivered today.
Namely for the way she handled our personal situation in showing true vendor concern for a customer in need. True customer service the way it used to be, and of course a resolution for us on our immediate problem. And of course for understanding the situation/need/demand that all benefit from, if the items are still available. She made the decision to call for a higher level meeting at QCC to discuss this situation. That's a person that cares, a rare quality today. We all of course assisted in helping them decide to go forward with it.

One of the greatest "issues" we had with our 1993 U300 was that parts were becoming difficult to find, and people who could work on the Detroit were rapidly retiring. We spent a couple of weeks at Cabin Diesel in Big Cabin, OK because Foretravel took an off-the-shelf hydraulic pump and used a gear with a 1/2" longer shaft (making it a custom pump). If we had purchased another Foretravel it would have been somewhere around 20 years old and we would have been looking at some of these issues.

It is really good to see that at least one component is going to be kept available after it would have been retired and there are companies out there that are willing to help out those who choose to keep the classics going. Now, the big question: what OTHER parts are either in the same boat as this pump or are soon going to be there? Can you point to this incident and get those companies to also step up?

Since all of the DP companies seem to be limited to Cummins engines, maybe that isn't as much of a problem as it might be.

Again, congratulations to all of you who were involved in solving a serious problem. It seems that real customer service isn't completely dead.

Thanks for your efforts. My 2008 Foretravel Nimbus has the discussed 41188 pump, which is failing as of yesterday. It making an extremely mechanical high pitch sound.

domotang,

Welcome to the Foreforum.

If this is indeed a noise from inside the pump (VS belt noise), I would not run the engine-- you could be sending shavings into your cooling fans and power steering pump.

To check, remove the belt and turn the pump by hand and check for play.

Thank you! The belt is off.

There isn't any play in the pump. It turns smoothly.

There are however 3 or 4 light 'click' sounds coming from the back plate of the pump per CW rotation of the pulley when done by hand.

The tensioner pulley seems fine.

Hydraulic cooling fans spin for a few seconds upon starting the engine when cool, then both stop at same time. I was under the impression they should always be spinning.

I'm not driving it until resolved.

When were the oil and filters changed last and what oil are you using,the tensioner may " seem fine" but may be bad,best way to
check is with engine running and look for bouncing,but follow above advice and don't run til you know more,check the condition of the oil by using the dipstick cap.

Thank you for the reply!
I didn't intend to hijack this important thread with other issues. So I'll start another thread if needed regarding the noise.
Been on the phone with Foretravel parts regarding availability, confirming that my pump is NLA at the moment.
The tensioner has been bouncing for a month now. So I'll verify causation.

I AM THE ORIGINAL POSTER OF THIS THREAD.

Simone Morris' email is correct in my posting on Page 3. (IRISH no doubt made an honest mistake)

DOMOTANG,
ive been all through the 41188 recently. VERY light clicks were heard in mine, but only when it was on the bench and was not flooded with fluid. There is a bit of slack in the gears as they rotate (dry) and I felt that is what i was hearing. There is nothing internal that would cause a squeaking or squealing unless maybe your are running it dry. The 2 very hard shafts run on bronze plates, dissimilar metals can squeak if not properly lubed.

1st if your tensioner is bouncing, that is not good and could be detrimental. I would immediately order a new tensioner and the heavier belt I mention earlier in this thread. Dont run it until you replace those and the next.
2nd I would consider a filter/fluid change based on what you mention above.....especially if you have no proof that it has ever been done.

YOU will receive no assistance on this matter out of MOT or FOT, Trust me ive been going through this for weeks. Dont bother calling either, your wasting your breath and time.. FOT has at least admitted it needs attention. MOT closing statement was to consider re-engineering the system.

I suggest you read this entire thread, to fully understand everything. I posted a video on a properly running system for example.

Personally knowing what I now know about the internal workings of the pump, and what you say is happening. I'd replace the belt an tensioner, filters and fluids, if still internal squealing, shut it down and plan to pull the pump for inspection. The seal kit is readily available through QCC I mention the part number and price in an earlier post. Not a hard job, just nasty.

Folk's Don't Panic.  The parts you need are more common than you realize.  How many sets do you need? 25? 50? 100?

A hardened shaft running on a softer metal lubricated by oil is called a plain bearing.  The bottom end of almost every internal combustion engine uses plain bearings.  The do however rely on a precision fit to work properly. So you need at the very least new bronze bearings.  As for the gear teeth, those are shaped for moving oil more than transmitting power from one gear to the next but I can assure you that the cutting tool for that shape is available in a catalog.  The steel used is no great secret, and the hardening process uses high temperatures in a propane (for the carbon) atmosphere.

"I" have made and could again do so make these parts, but as my time grows shorter I choose to spend my time on my own endeavours.  Or to put it more plainly, There is no need to re-invent the wheel and This ain't rocket science folks.

FWIW This spring, 1 May the fiber timing gear in my Studebaker chose to join the Choir Eternal, and "as long as I was in there" I put new gears in my engine oil pump.  Reproduction parts for my orphan car are readily available:

I could not agree with you more, but amongst all my many skills, I am not a machinist, nor do I really care to be.

I went to 3 different machine shops on this matter, and the story was the same at every one....They ask what its used for, I told them and they all reply the same. We are not going to reproduce any component of any item that is related to a safety system (steering) of a vehicle. Yeahhhh....I could keep trying and just lie about it. I Myself was able to get the shaft I needed along with another as a spare. But that is not going to help the masses of end-users out there with the same pump or parts.

A lot has changed in our American culture in the past 20-30 years. Everybody wants to sue everybody else for little of nothing. Guys like us that can fix/build/manufacture just about everything are rare. Those that do it at a profession will NOT assist in anyway due to simple liability. I have DIY all things in life for my entire life, worked heavy industry for 40 years, I too feel this is not a major thing. But based on what I say earlier in this paragraph, it is a major deal that no one wants to deal with.
.
Luckily by my efforts, along with the support of all here and on other RV forums, The OE manufacturer (QCC) has decided to continue the product availability....THAT result will help all,not just me.

Maybe someone could provide the forum members with the year and model coaches that use this particular pump that is also used for the power steering? If that is the only reason these shops won't rebuild the pumps, they may rebuild one if it isn't associated with the power steering.

Our 95 has the power steering pump attached to the air compressor and is gear driven. The Hyd pump only supplies the cooling fans but it is belt driven and appears to have the same tapered / keyed shaft.

I would think a good machine shop could make a new shaft based off of the old one without worries of liability. Mine only needs a new seal as it has a slow weep.

Per the parts manuals in the forum library:

Build number 4794 for the U270/U295 - 41188
Build number 4590 for the U320/GV320 - 41078

We do not have parts manuals for the U225/U240/U280/U300 coaches.  It could be a bus-style coach (1995 through 2006 ) implementation only.  We also don't know how the Nimbus/Phenix/IH/IC/Realm coaches are configured.

(not to hijack, but Nimbus/Phenix coaches have a whole 'nother issue with the hydraulic fans/dry PTO that drives them, but that PTO only powers the cooling fans, not the power steering)

Actually, my' 08 Nimbus' hydraulic system powers the radiator fans and power steering. In fact, it uses the same 41188 pump at the center of discussion here and near identical hydraulic fan motors. Fans themselves are completely different though, and I'm trying to source them.
Foretravel outsourced the entire cooling system (pump, fan frame/box and all) to a company called Hydraquip in Houston, whom I'm in current discussions with for sourcing parts.

That's good news that you at least don't appear to have the dry PTO issue.  Here's the discussion/outline on the 2007-2010 Nimbus/Phenix that do have the problem Break down on I-10 (fan pump failure)
