After removing the 12/1 electric start units from our sales list, we are pleased to make mention that we have reintroduced the engines for resale. When we received in the engines, we were displeased with the excessive vibration and refused to sell the units until we could find out what was wrong. We had sold two of our generator sets to customers who called us to complain of the problem. We ended up bringing those units back in and exchanging them for hand crank models. We worked tirelessly with Atul at Anand to solve the problem. He continued to make note of the fact that these engines were tested at their facility and did not have the vibration problems we spoke of. We re-designed our skid base and added the "cushy foot" vibration mounts that Atul recommended. What we found was two-fold. First...prior to our modifying our skid base, the engines would shake and "walk" their way across our parking lot. There was way too much flex for this powerful engine in the skid base we had been using in all of our builds. We made some changes and beefed things up where needed and now have a new skid base design that helps absorb some of the shock from this big stroker.Second,with the addition of the "cushy foot" vibration mounts, this is one of the smoothest and most impressive builds yet. While the engine has not been modified, the skid base changes we made has "quieted down" most of the vibration and the vibration mounts makes this a most pleasant unit. We have decided to continue to offer this unit as part of our product line, but will recommend (and supply the plans, if you want to build your own) the skid base design our techs came up with as well as encourage the use of rubber vibration isolators. We feel the 12/1 electric start is an impressive unit and has much to offer for various uses. Our thanks goes to Atul and his patient and understanding engineers/technicians for their help and support through all of this.....Thanks! Phil form Central Maine Diesel
