Cannot be done?
In early May of 2014, New England Truckmount made PTO installation history. In the winter of 2013, we were given the task of installing a White Magic Pro-1200 direct drive unit into a 2010 GMC Savana 1500 cargo van with a 5.3 litre engine. It was a custom install, moving the equipment from an extended 2500 into the standard-length 1500. Ordinarily, PTO's are simply not installed into 1500's, but since the customer was not a carpet cleaner per se, he insisted and wanted it done with vehicle suspension upgrades.
All later-model White Magic direct drive units (and some others) require that a distinctly-sized bracket be installed directly over the vehicle's alternator to properly align and mount the equipment's drive shaft. This is absolutely critical to assure the drive shaft is in the correct position and maintains the proper pitch to run the machine. Only the smallest 105amp alternator (or a small remanufactured 150amp) could be used. When the destination vehicle was supplied with a larger alternator, the smaller was chosen without any problem whatsoever. Why? Both had their own independent voltage regulator and the smaller one always sufficed for any GM. Larger ones simply get in the way of the required bracket and it could not ever be done.
The first part of any PTO installation is the front end work: crank shaft changes, belt tensioner, idler pulleys, and the alternator bracket. Right off the bat, it was reported that the vehicle had electrical issues and that the battery could not charge properly. Although this was in fact after the replacement alternator was installed, the essential problem was unknown with current testing equipment and staff. Long story short, the vehicle would not charge properly below 1,000 RPM's. This was a huge problem. After much time and expense, we learned that this particular vehicle had an ECU-controlled alternator and simply was looking for the one it came with: the large one that could not be used for the install.
Working closely with an automotive electrical expert, a possible solution was to manufacture a custom alternator pulley for the intended smaller alternator. The design was to create a one-third smaller one to spin the alternator faster, thus generating more power to the battery at RPM's less than 1,000. After a week or two, we were told by our machine shop rep that it could not be done. The angles and size of the pulley overall could not be made. They couldn't do it.
Here is the pulley we had made for us by a new vendor. It was perfectly machined, and fit the alternator like a glove. Unfortunately it did not solve the electrical issues. The ECU of the vehicle would not compensate and was still looking for the larger stock alternator to send the signal. Although the theory was correct, the application did not work because of the way the vehicle's computer insisted. In the end, we gained great experience, a valuable new vendor, and nothing short of a very handsome paperweight.
In the winter, we hired a new shop technician, Steve. A technical college graduate, Steve brought with him a huge array of professional tools, excellent domestic and foreign automotive experience, and welding and fabrication abilities. He was extensively trained by industry experts on all facets of the company's shop operations and has exceeded expectations in no time at all. With his help and high expertise, we gathered what was needed to deal with this problem. In addition to Steve's professional scan tools and research, we had other professionals come in to reprogram the ECU and assess the situation. This vehicle was very adamant though... it was totally unwilling. It still wanted that large stock alternator. Repeatedly we were told that it could not be done. I refused; he also refused. We worked together as a power team.
Through his research and abilities, Steve and I worked together for a solution. We found an ECU-controlled alternator smaller than the stock one, but was too big for the bracket and the drive shaft. Steve said right from the beginning that the bracketry would have to be made custom, and that's exactly what we chose to do. The whole project was engineered so well, that the drive shaft was exactly where it needed to be. Absolutely no new belts were required and everything was installed in perfect alignment, exceeding factory specs. Final customizations were done, and the machine received a well-deserved fresh pump and blower oil change prior to testing.
The vehicle was delivered to the customer the next day. It could not be done without our new shop tech and our unwavering commitment to our customers. Many thanks to Steve for this. He received a handsome bonus from the customer and the company alike.
