Marilyn has always treated us with the most upmost respect. And you can tell she has passed it down when you call in! Customer – Quality Hydrostatics, Inc.

The first was the company reputation. However, the biggest reason was an individual by the name of Phil Hoffman. he worked with me for several months to enable me to fit one of your couplers to an application I was working on. I am glad to say that that application/project is complete now and is working better than I had thought. Many thanks to Hayes and Phil for their willingness to help me and to rapidly contact me when I had a question. Customer – End User

We contacted Hayes Manufacturing, Inc. (Hayes) approximately 20 years ago to help us develop a drive line part for the Porsche 928 model. The drive line part replaced an original Porsche part which did not function as designed and could damage the engine of this particular model. After the successful completion of this project, we worked closely with Hayes to develop other high end drive line parts for other Porsche models which have been a great success for our company. Hayes’ staff have always been professional, timely and very helpful with the demands we have made of them. Our company would not have been as successful, and probably would not have survived, without the relationship we had established with Hayes at the beginning. We cannot recommend them more highly.  Customer – Cartersville, GA

Hayes is a great source of information and supply on drive options for our Kubota engines. They are easy to reach by phone or email and we always get an answer. On new applications they are willing to find the answer in a timely manner. It is valuable to know when we might receive product and we can always request a different lead time. At least they will answer even of too busy to fulfill or parts have to be made. I do not hesitate to recommend them.  Customer – Reynoldsburg, OH

We have used Hayes manufacturing for decades for our power take off needs. They have always provided quality products at reasonable prices. Equally important is their willingness to help you find the exact solution needed for your application. It is a pleasure to work with them!  Customer – Rock Hill, SC

We recently started working with Hayes, after years of seeing their products in the market place. Their extremely quick supply has helped us capture OEM business prototype business, we typically have not been able to lock down so quickly. As a system integrator, my company needs one or two pieces for rapid prototyping regularly. These then turn into larger orders, spread out over predictable times. But the key to getting the production order, is achieving/surpassing customer’s expectations during prototype. Hayes has been great at getting projects off the ground.  Customer – Mt Pleasant, MI

“The Bearing Supported Stub Shaft arrived here Friday early afternoon.  As a long time engineer I must say that it is a work of art, in design and manufacture.  It was nice that everything was there including the Bell Housing bolts and even spline grease.  It assembled on the engine quick and easily with precise fit and finish.  We couldn’t be more pleased.   I want to thank you and your staff for all the help you gave us and for getting the kit out in a timely fashion.  With a bit more assembly of the hook up Megansett Harbor Company will indeed be ready to brave any storm that should come along.  Having a real Bearing Supported Stub Shaft makes this a first class installation with unquestionable reliability and longevity.  Again thank you and all the best.  If you ever need a reference I am here for you.

A quick addition: I teach engineering courses at Maine Maritime Academy part time. My wife and I had a few students over yesterday. They were equally impressed with your work. Good example how to do it right for these budding engineers.  Best regards, Rick Armstrong, President & Owner”

“Why else? quality product, when ordering? quality svc, professional / efficient team work.. Can’t go wrong: From Mrs. Hayes acknowledging order that was sent, I didn’t get back right away to her prompt email questions? She passed the order/ notified sales team, I called and there was Allison jumping in to finish the order. NOW.. if I can get the other 120+ vendors that I use to do that? It’s nice to dream, but reality is that as stated? Quality product and service? That’s a rare thing these days. Thank you!” Customer Remediation Svc.Int’l.

#1 reason? more of a conglomerate of reasons: quality of product/ service, team work exuded by Marilyn and Allison? all add up to 10’s across the board. having over 145 active vendors whom I deal w/ constantly? rare I do surveys… can’t keep up if I did. I HAD to reply/ compliment. Only fair when you get Svc like this. Great job ladies. (and Hayes team too of course!) Bart M. Borden: Ops Mgr, P/A and whatever else I need to do to keep us moving fw! thx again.” Customer – RSI

“I just wanted to drop a line and say Thanks! I worked with you to get a hydraulic pump mounted on my Kubota Diesel engine to run the hydraulics for my pump pulling rig. After using your setup for almost 2 years I can say your products are simply awesome. They are machined to exacting tolerances and the engine housing looks like it came with the engine. And it’s built extremely tough, I can see it will last me a lifetime. I have bragged to everyone that you guys are the only ones to contact. If and when I switch engines someday, you will most certainly be my first and only call. Thanks again for a superior product and excellent customer service.” Customer – Maurer Well Service, MI

“Thanks a bunch for getting the final design spec and quote over to me. I just spoke with Anna at your office and provided her with the shipping and payment info. On a side note, your estimate was just about spot on, and I’m not sure how you and your team make it happen, but the pricing for this item, seems surreal. I am officially impressed by your organization. Keep up the good work.” Ricky from CA

“Regardless the outcome, however, I would like to commend all the folks there at Hayes for their prompt replies and sincere interest in this matter. Its refreshing to deal with a company today that still maintains the (old world) customer relations spirit … THANKS !!! ” Customer from Texas

“Anna, Part arrived and we are already under sail out of Boston!! Thanks so much for your help and excellent service!!! Fair Winds!, Beth Doxsee”

“Thanks for the follow-up. The project is still active and you gave us everything we asked for as usual! We dont need a follow-up call at this time. We have a fair bit of design work on our end before this project gets to the purchasing stage, but when that happens, we plan on using your coupling. We also think the price is reasonable considering the quality of the product. I deal with Mike Lawson a lot, and he always responds right away with drawings and cad models. This works great for us and is another reason to use Hayes products.Thank you!” Customer from the Carolinas

“You guys are still my preferred supplier of couplings and you always meet or exceed my expectations as being my supplier. I would and will always recommend your products. Best regards, Andrew” Customer from the Portland

“Hi Carol, to answer your questions, Yes the quote info was what I wanted Dont need additional info at this time Dont need follow up at this time Your pricing is excellent. Summary: I dont need to go anywhere else because you have the product, Mike is always knowledged and responsive. In fact, your company is one of few left that have real people addressing needs that are always NOW and not some voice mail that may get address later. In specific regard to the quote, I dont have a need at present. Im dealing with a customer that is always switching specs so Im always providing them solutions based on Mikes timely information” Regards, Mark

It is a pleasure dealing with everyone in the organization, and Mike Lawson has always been extremely helpful and one of the reasons I continue to call back.” Customer from Indianapolis, IN

“Speaking for myself and my colleagues, Hayes is a benchmark supplier that we wish our other suppliers would aspire to in terms of quality customer service, quality products and effective communication while still retaining a competitive edge. Naturally this mirrors our ethos. Suffice to say, we are conscious on a daily basis of wanting to grow the Hayes product line as much as possible which compliments our engine lines perfectly. Later this month we are exhibiting at the Atlantic Heavy Equipment Show in New Brunswick where Hayes will be heavily promoted along with our other products.

Hayes Product Sails The World

11/5/08 Singapore

I am a full time cruiser on a 35-foot Cherokee Catamaran (circa 1975) that was installed with originally a Perkins engine hooked to hydraulic pumps and two hydraulic engines. In 2001 while in Trinidad I re-powered with a Yanmar 3JH3E attached to a Parker dual hydraulic pump through a Hayes coupler system. Six months ago, in Australia, I again re-powered with a Yanmar 3JH4E and the above Parker pump and Hayes system was reattached to the new engine.

About a month ago while sailing up the Indonesian archipelago the two bolts that attached the pump to the engine housing cover either they worked loose or just stripped their threads. In the disengagement some of the spline teeth took a beating but being in the middle of nowhere I managed to reattach the pump to the housing using imperial inch bolts which managed to rethread themselves into the aluminum housing. This lasted for about three weeks enough to get with 50 nm of Singapore when all connection between Yanmar and pump ceased. It turned out both the teeth on the spline and the Hayes female coupling had stripped totally.

I was close enough to Singapore to sail the remainder of the journey over the next week.

Mike Thanks for the prompt reply. In answer to your questions the measurements are as follows: The over all flywheel diameter is approximately 11 3/4 inches, but the area that the plate fits into on the flywheel is 10 3/4 inches. And in fact the old plate measures 10 13/16th inches. The flywheel housing measures 14 inches across and in fact the old covering of the Hayes system measured 14 1/4 inches across.

11/6/08 Singapore

Mike Thanks for the ‘bolt report’. I should have no trouble with the 1/2-13 bolts as I have a stock on board. As well it may explain why the pump came loose from the mounting surface in the first place. I think someone along the way used metric bolts instead of imperial to attach the pump and though it worked for a time it eventually stripped the threads enough to pop loose.

Such is the life of a cruiser. You have to watch every nut and bolt that a non-yachtie may use in any boat work on your boat and the reason why if at all possible do it yourself, – which is what I am doing with this project.

Thanks for everything so far. I will let you know how things go. I am headed to Tailand next week

This is just a small sampling of the praise we receive regarding the quality of our flywheel couplings, drive couplings, stub shafts, and our exceptional service.

How can we assist you?
