Title: steering gear box
Post by: lenspeiser on July 27, 2015, 08:02:24 pm
I have read through the posts regarding steering gear boxes and am looking into the red head box program. I am away from the coach so I can't crawl under it and check. Was there any other Sheppard boxes used in 99 U270 36' units than the M100PDP1?
Thanks in advance for the help.

They rebuild your box, no exchange.

Thanks for the info, Lon. I checked out redhead boxes today, and you are right about the no exchange (at least on this model). Now the question arises, is the redhead box that much better than having a local DFW rebuilder just go through it? Has anyone out there had experience with both? The logistics of having to send the box off, have it rebuilt (although amazingly quick) and returned throws another wrinkle into the equation.

Thoughts or inputs?

The delta is will you find a local firm that will BLUEPRINT, or just rebuild.  Big difference.!

Blueprinting is the only way to really take all the play out of a Sheppard box.

Gotcha, Brett,
So I might move from 3" of free play in the steering wheel to 3/4"?  I had seen a post about the Howard steering stabilizer and had read about that. Could it be that the Howard centering mechanism was an answer to what was an original box with too much play, or were they really tight right from the factory? Just curious.

Brett, I have been seeing that Blueprinting is better and assume it will be set with minimum tolerances, but why is call blueprinting and what is done to control tolerances?  Does it take experience, tools, gauges, etc?.  Any place to read about it?  Google did not answer it for me.  Barry

Barry,

No first hand knowledge of RedHead or of the process they use to blueprint the boxes. Long ways from S Texas to Washington state where they are.  If we ever get up that way, will certainly make a point of going by.

My PRESUMPTION is that they use ball bearings of different sizes to take the slop out of the boxes.

I do know that Hendersons, Precision Alignment, etc do use them and highly recommend them for tightening up steering systems with Sheppard boxes.

I used to have 3" of free pal in my steering until Bernd worked on the bus a couple of weeks back - now it is maybe 1/2" - I thought it would need the steering box rebuilt at 109,000, but in my case it was a two steering arms that were replaced.  $750 late and down the road in good shape.

Moral - if you have not been diagnosed, it may not be steering box

Thanks for that reply, Tim. Had the coach in at FOT to check on a seep in the box. I was told it was not just seals but the box needed to be rebuilt, so I am looking at different options on how to go about this.

@enspeiser, I'll be at Redhead the end of August to have my Sheppard rebuilt. I have about 1/4" to 3/8" of play and that's too much for me. :) Probably too late to be of any help to you but I will share my experience here when done.

I chose to send RedHead the box because I could NOT trust a good local rebuilder.
IT'S WAY TOO MUCH WORK to R&R  and take a chance on poor performance. If I had a local shop that had good recommendations I would might go there.
RedHead received the box, rebuilt it, and shipped it back the same day. I paid about $100 to ship it to them in Seattle from Chicago via FedEx. RedHead charged me about $40 to ship it back to me. If I was doing it again I would ask them for a shipping label at there shipping cost when I sent it in. As I remember the total cost including shipping it back was about $500.
To me it was WELL worth the S&H logistics to send it to them. They are also FANTASTIC to deal with.
Besides, Who can resist a REDHEAD!

More good feedback! Lon, did you pull the unit and install it yourself or hire it out? If you hired it out, do you remember how many hours of labor were involved? How do you determine whether the limit adjustments were correct, or did you do those yourself?

I can tell you that the redhead is looking quite alluring so far!

Yes, min is not leaking, but I had really annoying play - I suspect at some point mine will leak, and at that time I will go for the "blueprinted" version.  Was happy Bernd could solve most of my "dead spot" so inexpensively.

It cost me about $1000 for a rebuilt box from Shepard and $910 for the removal and installation five years ago.

Bernd replaced our very leaky steering box last November with a factory rebuild.  I didn't realize how much play I had until it was gone.  It is a bear of a job- glad I had good people do it.

Post by: Barry & Cindy on July 29, 2015, 02:10:58 pm
Thanks Brett,

Very interesting that using larger ball bearings could reduce slop.
Where does the word Blueprint come front?  Why does 'Blueprint' mean closer tolerances? Barry

Again, have not observed the process, but achieving exactly the proper clearance between gears would remove slop.

Am sure someone will google and get the right answer, but it is a term that has been used for many decades to signify a machine brought much closer to design tolerances than the wide range acceptable for "normal" production.

I did the replacement myself.
It was not easy. It is HEAVY work, but I found it do-able. I would not hesitate to do it again (would have a long drinking binge and huge pity party before hand though). I'm 62 with 2 bad shoulders but was always able to find a way to out muscle the gear box. I did need Cheryl's assistance when I had to bolt the box back to the frame. Her judicious use of a pry bar in positioning the box while I started the bolts was appreciated as was turning the steering wheel while I re-installed the pitman arm. Other than that its a one man show.
Let me know if I can help.
RUDY gave me valuable advice BEFORE I started. His words of wisdom made the job happen. He had suggested a re-builder in TX that he had good success with.
If you decide to do it yourself I'm available to help you any way I can. I have tools I will lend you that will be needed. Some you will have to buy, but the cost will be FAR less than the labor and the box costs.

Lon,
We must be twin brothers from separate mothers! I do appreciate all of the input and advice. I have a while to work through this as we are not full timers yet. One thing that I have seen from posts with pictures of the process is removal of the headlight housing. Is this for access behind the headlight or for access THROUGH the headlight opening? My coach had the headlight conversion done before we got it, so I don't know if that will make it even harder.

I am glad that you gave your project supervisor proper credit for the timely and precision application of mechanical advantage. I find myself not thanking mine enough. After all, while I am merely the pilot of the coach, she is the nagivator.

I will be visiting with you soon.

Bernd needs to get a web page.  People on the Forum keep recommending him, but all they can provide is a phone number...occasionally a street address.  If you Google him, there are practically no hits.  A talented web page designer could really help him get his name out there.

Or perhaps his shop is already so busy, from "word of mouth", that he doesn't need any publicity?

Bern'd is excellent about responding for assistance even when the request is after hours. Based on my experience, he does not need a web page but another FT tech.

"dabbles"....  :giggle:

For those going to Bernd for the first time, keep in mind he, like Xtreme, are cash and check only, no plastic.

Talked to Redhead Steering Gears yesterday. Found out they are not set up to pull the steering gear. You need to have a shop pull the unit (or do it yourself) and send or deliver the unit to them. They will then rebuild it within 24 hours. Asked the guy if they could eliminate the 1/4" to 3/8" play I have in my steering. He said if it's in the steering gear they can. Also asked what they do to the unit and he ran through a list of things but instead of me listing them here I found this on their website.

Red-Head Steering Gears Re-manufacturing Process

    Machining out the housings and installing needle bearings
    Flame-spraying or replacing the shafts as needed Installing new control valves on some applications
    Custom fitting each worm & piston assembly with special ordered, precise over-sized ball bearings.


Other things we do to produce a top quality product include:

    Install every sector shaft on a lathe to check for straight and true,
    polish the sealing surface to a higher polish than new.


Some original housings are manufactured without bushing or bearings. This is commonly seen in some Ford steering gears and Chrysler steering gears.  We rebore these units and install needle bearings.

We use only the highest quality seals. All our seals are either O.E.M. or produced by two high quality, long time suppliers of our industry.

Probably the most unique and important thing we do is custom fit every single worm and piston assembly with new precision fit steel balls. This is a process not matched by any other company in the industry. This process is very important. The machining tolerances of the original manufacturing leave a small and varying amount of play that can be corrected in no other way.

Why don't other builders do this? It is expensive and time consuming to set up. This is one of the reasons you may find another unit somewhere else for less money but the quality cannot be beat. This is why we proudly declare that we are "Not the Biggest... Just the Best!"

We also stock what we have found to be the highest quality RACK and PINION units available. Although these units are not built in-house, we have selected the highest quality manufacturer and product we could find. They have the most comprehensive testing process in the business

I did not remove the headlights. I could see no advantage to doing this. I have the Kubota 4cyl. generator with the cooling fan and radiator located in the front drivers bay. The radiator exits heat into the front left wheel well.
After the fanbox and radiator are removed (good time to paint and clean both) the rubber compartment walls and floor are easy to remove. This leaves wide open access to the left side of the steering box. No need to work at it from the headlight area.
When the generator is slide full forward the access panel behind the generator floor is removed. I cut mine bigger so I would not have to struggle in the small provided space ( I made a new larger cover). You then remove the panel to the left of the generator wall (sheet metal screws) and there is full access to the right side of the steering box.
Its ALL MAN VS MACHINE from that point on!

My steering gear is also leaking. I live in Houston and was planning to take it to Chalk's Truck Parts for the rebuild...but after reading all of the info and reports on Redhead I think I will send it off.  Seems like a leaking Sheppard steering gear is a common problem. I am curious if anyone that has had one rebuilt by Redhead has ever had it leak again?
Title: Re: steering gear box
Post by: Green99 on July 31, 2015, 07:45:51 am
Len,
I noticed you had the 270, I also, have the 270.  The gear is very accessible, by removing bottom gen set cover (2 nuts on frt edge and 2 bolts at the rear).  Slide the generator all the way out and the access hole to the pitman arm and mounting bolts are easy to get to.  Also, going thru the frt. drivers side compartment gives you easy access to the lines and steering column mounting.
I recently replaced the top seal and moved the leak to the side cover, and figured rather than continue to chase the leak I would have it rebuilt.  I didn't pull my gear due to the weight and the fact I have a ruptured disc, and the fact the puller is about $140 on Ebay and a shop pulled it $150.  I couldn't find the $10 savings worthwhile.

Karl,

You might want to search the forum for previous discussions on the Sheppard unit and Brett Wolfe's (wolfe10) guidance to make sure you have the stops set correctly for your coach (I don't believe this is something that Sheppard can do for you) to prevent premature failure or a recurring issue, especially related to leaks.  I believe Dave (JD) Stevens has posted how he and Marilyn did this themselves.

I have seen Brett's comments and discussions. In fact that is what swayed me to go to Redhead instead of a local shop. I  also have watched the video on setting the stops. Plan to pull it off Sunday and get it shipped put next week. Mine only has 25K miles on it. It went bad sitting in storage. I will check out JD's post as well.

I have mentioned this before, and will again now.
If you need the Sheppard pitman arm puller I have one that is available to borrow. You pay the S&H both ways. I also have the 3/4" drive socket to remove the pitman arm retaining bolt.
Just call or email me.

Post by: Barry & Cindy on August 01, 2015, 08:35:32 pm
Lately, if we think of it before turning off engine after parking, we leave the steering wheel and front tires not facing forward, so the pitman arm weight does not hang in the same position.  I hope this will help the shaft seal from being deformed in the same place and preventing oil leaks.
I got the idea from our Forum.
