Replacement Muffler for Gas Engine Air Compressors - Honda GX630, Kohler CH13 and CH440
The muffler on an engine driven air compressor takes more abuse than the one on a mower or a generator. The engine pulls hard under load, drops to idle, and comes back up to speed every time the tank cycles, all day, usually on a service truck where it is also getting rained on and knocked around. They crack at the weld seam, rust through at the bottom, or lose their internal baffling and simply get loud.
These are direct replacements for the engines used in ACS and AirComParts gas compressor packages.
What fits what
- M5038: muffler for the Honda GX630 engine
- M5046: muffler kit for the Kohler CH13 engine
- M5047: heavy duty muffler kit for the Kohler CH440 engine, supplied with mounting bolts and washers
Muffler or muffler kit
The Honda item is the muffler itself. The two Kohler items are kits, which is how exhaust parts for these engines are normally supplied: the muffler together with the hardware needed to hang it. The CH440 kit is the heavy duty version and comes with the bolts and washers, so you are not hunting for fasteners after you snap off the originals.
Before you order
Read the model off the engine tag rather than working back from the compressor model. Engine driven packages get repowered over their life, and the engine on the machine today is not always the engine it left the factory with. On Honda twins the tag is on the blower housing; on Kohler Command engines it is on the shroud above the recoil or starter.
While the old one is off
Check the exhaust studs and the gasket face in the head. A muffler that has been loose and rattling has usually been leaking as well, and a fresh muffler bolted to a pitted face will leak too. Replace any stud that is stretched or has damaged threads rather than torquing a new muffler onto it.
