rebuilding a old ONAN engine BF-MS but have to find just one more part. Does anybody have just one(1) "good" piston for a 16HP 40 cu in onan. It"s for the 3&1/8th inch bore. not the 3&1/4. Thanks
Your best bet is Onanparts.com, Your Onan Parts Solution. Call or email them and request the part you need. They've been very helpful in my rebuild of my Miller 225nt. Will be using them again on an Onan 4kw genset. Yes the prices can be abit more than other engine repairs but you'll be assured of getting a good part.
