My Generac Q-55G, 5.5KW, 120V gas generator runs Ok but leaks oil like a sieve through the bottom crankshaft seal, even when it is not running. I've tried oil additives to no effect. From what I've read. this is not an uncommon problem with this model and the repair involves removing the generator and tearing it down completely. I've decided just to replace it.
I cannot find an exact replacement (which I don't really want anyway) or any other model or brand of the same power that will fit in the same hole. The Generac is 25"L x 18.5"W x 15.75"H. An equivalent Onan, for instance, is 33.6"L x 22.2"W x 16.7H. I might be able to deal with the increased width and height but there is no way I can deal with more than a 25" length.
Part of the reason the Generac unit is smaller is that the muffler is mounted outside of the enclosure. The other is that the newer generators are shrouded with internal cooling blowers to reduce noise.
Has anyone been able to successfully deal with this problem?
Thanks in advance for your help.
