There are 3, not 2. Nelson 84101B. I hope you used teflon based permatex on all of the pipe threads. Per Foretravel. I had no leaks, and just filled with oil and fired up.

A bad shoulder does not mean one cannot use their mind to be of help.

What the photos of Ken don't show is that he had more grease on his face than on his pants. He cleaned up very nicely for cocktail hour. We told him about the greasy face about an hour later.

@Kent Goop is your friend!

@twig Thanks for the tip. I didn't use any sealant. Turns out Kent was helpful a second time. In his vast collection of solvents and sealants he had a bottle of Permatex Thread Sealant with Teflon! I guess I get to crawl under the coach again...

Ken,

It's a positive displacement pump so it should prime itself.

@Twig I hate to say but you were right. The seal did nothing to stop the leak and in fact may be worse...

I did turn the pump by hand and it started leaking just from that. I did manage to turn it enough to cause the radiator fan to spin. So was an easy prime as Pierce mentions probably not necessary. I did start the engine and let it idle for a minute or 2. Leaked the whole time. The good news is that the radiator fan motor isn't leaking. (yet!)

Twig your message implies you bought a new pump. Where did you buy from? Would like to price a new pump and decide to rebuild or buy new.

I'm really not looking forward to pulling the pump again. My back is killing me. May have to take a day off first.

Wellllllllllllllll, I have good news and bad news. Which do you want first? K, first the good........I got the pump from Foretravel. Now the bad....according to Mike Grimes I got the last one. Not to say that maybe they didn't get more. The new one is a different manufacturer and I don't remember the name, but Grimes knows his stuff. Give him the model number of your old pump and see what he can do. As I recall the new pump was around $700 and an exact match.

Well I pulled the pump the other day and took back to P & H. They apologized profusely and said they needed about an hour to look at it. Went to breakfast at Waffle House and when I got back they had the pump apart and the front desk guy was carefully mike'ing the pump shaft to find the exact seal for it. Said they would have to order it and would have it the next day.

Picked the pump up today. The guy that brought the pump up from repair was a different guy than before and when I asked about why the seal had failed he mumbled something about the bearing was messed up. I don't think he knew any of the back story. The girl at the front desk handed it over and said no charge. At least that made me smile.

Got back to the coach, put on my filthy work clothes, put the pump back on again and refilled with Delo 400 15/40w again. Cranked pump by hand till the radiator fan started spinning then started the engine. Ran for about 10 minutes without a drop of oil showing up. Hopefully it's fixed for good. I'll take it out for a test drive tomorrow just to make sure.

I'm headed towards Memphis on Monday so will be watching it very closely. I'll post some follow ups on my way.

Don't really know what the issue was whether they nicked the seal when they installed or they spec'd the wrong size. Doesn't really matter much. They made it right. That makes me a happy guy.

Excellent Ken! Glad you had the time and persistance to get it done. How about sharing the seal manufacture and part number if you have it?

How did Tide do on the shirt?

I can put on a fresh shirt and ruin it in 5 minutes.

Great news Ken!

I hope all of your efforts and back pain result in a job well done and no more hydraulic fan pump trouble. Saving big bucks and doing it yourself is a very satisfying experience and gives the rest of us do-it-yourselfers a big boost!

The bill for my pump/fans that were replaced/repaired by the prior owner back in 07 was almost $2000.

If your going up Hwy 49 through Gulfport via Hwy 90 on your way to Memphis honk those dual Hadleys and I will step outside of my shop and give you a big thumbs up for a job well done!

No longer a happy guy...

Stayed at the Walmart in Marianna, FL last night. Got up this morning searched around for propane. Found some at McCoy's. They started filling it up and I ask how much are they charging. He says $4.99 a gallon. I said you're just messing with me right? He says no. I tell him to shut it off. Already had 12 gallons in so paid and left! I've been paying $3.50 or less most places.

We started heading north on Hwy 231 and pulled into a rest stop just south of Dothan, AL. Got out to do a walk around and the car is covered in oil!

The damn pump is leaking again. Limped into Dothan and found an RV park.

Went to a hydraulic shop and they said they would have to see it before they could tell me if they could do a rebuild. Went to another shop and he said they don't even touch pumps anymore. They had so much trouble with them leaking after a rebuild.

Called Foretravel right at 4:00 and Billy Jack answered! Explained the situation and he said that they didn't start keeping parts records until 94'. If I could get him the part numbers off the pump he could probably match something up. My project for tonight is to find the pictures I took and see if I can get the numbers off it.

Wish me luck...

Ken, Florida has always been a rip off for Propane, it was 4.15 in January in Davenport.

Sorry to hear about your hydraulic pump. If you were coming thru the Atlanta area i would attempt to get you together with the hydraulic shop that I have used with success. If there is any way that I can help call me at 770-595-3891.

Gary thank you so much. You are very kind to offer. For now I have my hopes pinned on Billy Jack. Hoping he can come up with a replacement pump. At this point I don't care how much it cost! (Hope Billy Jack doesn't hear that!)

Ken,

Sorry to hear of your leaking pump again. I saw in your post that you're are south of Dothan, Al. My pump was replaced in 2007 by Ray Thompson Auto Service, Inc. in Dothan (334-794-7272) businessfinder.al.com/935052/Thompson-Ray-Auto-Service-Dothan-AL I have a copy of the receipt from the PO but I can't tell the make or model number. My receipt number is 001771 dated 9/17/07. Hopefully they will have a record of the repair or the mechanic that replaced it is still there and will remember the pump that was replaced. I have the same setup as yours except there are two fans on my radiator. Hope this helps.

Good luck,

Jerry

@Jerry Thanks for the lead. I'll probably drive by there tomorrow and see if I can get any info.

I don't think your pump is the same based on seeing Kent's setup in his U300 twin radiator fan. Mine has 4 hoses and Kent's only had 2. His just drove the radiator. Mine drives the radiator fan and the power steering. Though I'm finding with Foretravel you never know what you'll find in what coach!

I've attached a couple pictures of my pump. First picture from below second is from above.

I noticed Grainger uses the 1800xxx number to identify their pumps.

If Billy Jack doesn't come up with anything I'll give em' a call. At least I know a price range. I guess I'm not allowed to complain if it's under one coach buck (1cb)

Ken,

The problem is that there are so many specs involved, shaft size, rpm, gpm, rotation cw or ccw or both, etc. etc. Difficult when you don't know the specs for the pump/motor you have. I have heard that Foretravel does not stock the OEM hyd motor but uses an Italian brand now with metric threads, ports in a different place.

Here is a quote from another RV forum about a Foretravel that ran into pump/motor problems:

"I am now extremely familiar with the hydraulic fan system in our coach and have learned a lot.
#1- Foretravel no longer stocks a direct replacement hyd motor. Problems...the new motor has metric threads so the fittings from the old motor will not work. Doesn't mount the same.
#2- The new motor mounts entirely different than the original and requires (2) adapters that must be built at a machine shop and they are $$$$$$$. #3- Due to the new mounting arrangement the hoses are not appropriate and on it goes.
#4- Foretravel only provides 90 deg -10 fittings for the motor and straight fittings would work much better. Again due to the pump manuf in Italy and tapped for metric fittings.............straight fittings not readily available.
#5- After I got the adapters from the machine shop (which were in accordance with the Foretravel Engineering drawings) I got under and assembled everything only to find that the assembly was 2" too far from the radiator shroud so out it all came. I fabricated 2" spacers and put it all back together. Now the radiator clearance was o.k. but the fan blade would not clear the corners of one of the adapters. An hour with a die grinder to take care of the corners.
#6- If I had it to do again I would pitch the whole system and buy from a company that supports their products.
Gary"

I can't say how accurate this quote is but it would seem that as our coaches age, there may be a shortage of some critical parts that could leave us stranded for several days. It may be time to list each Foretravel by year, engine, pump I.D., etc so we can either find another Barnes product like yours or match specs with another brand so we have a quick reference in case of trouble.

Here is another link for several repair centers for Haldex-Barnes hydraulic products: Hydraulic Supply Company Retail and Repair Locations Looks as if they were domestic but are owned by the Swedes now.

Good luck and keep everyone posted.
