Re: Engine Alternator use: Reply #78 – September 15, 2015, 11:23:05 am Quote from: Don & Tys (AKA acousticart) – September 03, 2015, 11:01:57 amThanks Wyatt, I have looked at the mounts many times and as far as I can tell visually, they appear to be sound. As I said, it isn't horrible, just noticeable. I think there is something rattling in sympathy with the generator frequency which adds to it though. I want to try and source some air spring isolator mounts for it but haven't got any leads yet on how to spec them out, other than weight of the unit and the mounting height dimension. I want to be able to add or remove air to find the mounts acoustically satisfying solution. Also, I will separate the radiator mounting from the generator as others have done with the 8KW units.DonPulled my 8kw gen. out for service yesterdaycombination radiator & 3 cylinder on one frame, earlier U270 application. Noticed I had broken 3 out of the 4 radiator isolator mounts. Most likely have been broke for some time, Really no movement because of the tight fit within the insulated generator box. Should think about separating the radiator from the Isuzu like others have done.Small Isolator Mount by Power Tech | Power Technology Southeast Inc Quote Selected
Re: Engine Alternator use: Reply #79 – September 15, 2015, 01:00:30 pm The isuzu seems to have a lot worse vibration than the four cylinder kubotas. Ive seen two of them with a lot of broken mounts Quote Selected

Ive seen two of them with a lot of broken mounts I think the most severe vibration / shake happens during a cold start or shutdown.Radiator isolator mounts are small and they just come apart, quarter inch stud pulls away from rubber.

Re: Engine Alternator use: Reply #81 – September 15, 2015, 01:36:43 pm I cranked up the RPM slightly to about 62-63hz no load and that helps some with the vibration on the izuzusususus. Relocated the radiator overlfow tank off the radiator too. Still shake...4cyl kubota is much nicer machine. I'd rather a honda inverter unit thoguh..super quiet and small. Quote Selected
Re: Engine Alternator use: Reply #82 – September 15, 2015, 01:41:35 pm Replacing generator mounts every decade (or sooner) is a good maintenance move. Rubber (like concrete) never stops curing. At a certain point mounts may look acceptable but are worthless just like an old tire.. pc Quote Selected
Re: Engine Alternator use: Reply #83 – September 15, 2015, 01:50:52 pm Look at the mounts from the bottom. While they may look 100% from a normal top view, they may be shot when viewed from underneath.Pierce Quote Selected
