hi all,
well, after hearing michaels generator when he was here visiting, i decided to go further down my qwest to figure out how to silence it some more. his actual diesel engine is about the same noise level as mine. i have put more muffler hangers on the exhaust pipe for the generator with no help.
so, i took the one hp motor off the blower fan and had it checked out at a motor shop. it is just fine. there is clearly more noise coming from the blower fan than michaels.
so i took the blower fan out. it is made by dayton which is owned by grainger and i happen to have an account with them.
i took it apart piece by piece. mine uses bronze sleeve bearings and they clearly were worn. i only have 1700 hours on the generator.
the blower unit minus the motor is a 2C975 and is not made any more. however, parts are available for it. so, new bronze sleeve bearings and a new shaft were gonna run me fifty bucks. however, i really wanted ball bearings to quiet it up. ball bearings that fit in the mounts were going to be more like eighty bucks.
so i opted to buy a whole new blower with ball bearings for 170. there is a steel bracket welded to the old one to mount it and a piece welded to support the motor i will have to put on the new one, but this way i am sure it will be quiet.
next i will trace down the entire exhaust system and see what is rattling there.
the new blower comes on monday so i should be in business next week if i can get it welded quickly. maybe it will be an excuse to go buy a mig welder.
