Sounds then that the rods let go.

I only read about CCK engines.... I could be wrong...

Sure seems like something should be hitting if rods are broken or have come apart It makes me wonder if the original issue was broken / loose rods and the owner took it apart to remove rods to eliminate noise and possible lockup then sell it as a decent motor with "probably just stuck valves" which would bring a higher price than connecting rod issues when it was sold "several years ago" Before taking oil pan casting off can you get a bit of a grip on 1 of the pistons and pull it out ? Clean any carbon off the ridge before trying to slide piston out GOOD LUCK Gary

Aluminum rods. Crank is unique to the Miller welders, early ones were tapered like the Onan gensets but a different taper. Later cranks are threaded to join the rotor.

One rod broke, maybe. 2 broke? Never seen that. Blocks are nearly identical to those found on the BGD, BGE RV gensets. The rods are not interchangeable with any of the CCK, CCKA & CCKB rods.

club
the CCK family of engines has NOTHING to do
with the P series of engines ( P 16, 18 20 )

welder cranks always seem to be different
than the gen set cranks.

i have had engines on site with BOTH rods broken.
99% of the time the broken rod is due to NOT ENOUGH
oil in the pan.
the # 2 rod is usually first,
and some times the operator does not catch it in time
and then the # 1 rod goes also.

thank you. boomer ( the used onan engine parts guy, also NOS and new )

I've read about the end of the crank being straight or tapered depending (tapered for generator service?) Something to think about during the acquisition phase of the swap

I ended up with so many projects in my garage that I had no room to pull anything apart so rather than make things worse I did a purge . I put about 10 ads in CL and so far 3 of them have sold. Another 1 or 2 and I will be able to swing a cat in there. I have 18-20 generators stacked up like cordwood of which 6 run so I have a long ways to go. Cheers Dan

Hey Dan, any of those MDJEs for sale that are not runners by chance come from a sound shield set up?

Sorry the only one I have running is the one with a sound shield. It makes a huge difference in the sound level. This is also the only magneciter set that I have that works. https://vancouver.craigslist.ca/pml/tls/6083734191.html
I have probably had 2 or 3 soundshields for J series over the years but almost every MDKD has one. Cheers Dan

Well, if any of the junkers have the intake manifold elbow adapter on them that goes to the canister style air cleaner assembly than I know of a good home for it. The elbow part at least. The sound shield enclosure equiped MDJ's came with them instead of resonators in some instances.
