Re: $6,600 to rebuild Atomic 4? replace/rebuild

Thanks Sloop,

I already had the crank ground down, and purchased the appropriate sized bearings to accommodate the new size. I bought a set of engine brushes, so I plan on going through the motor with them and ensuring all the gunk is clear and no remnants of glass are present. As for the rod honing, I'm not familiar with this procedure...the mechanic suggested that I hone a few pieces of the motor during the rebuild, but I haven't researched the specifics on this yet.

Thanks for the feedback, as for Porfin's posts, I have already gone through them several times and will definitely use his documentation as a guide in my rebuild...he did a great job outlining his rebuild!

-Chris

Resizing the rods involves having the cap mating surfaces ground down slightly to make the big end slightly "football" shaped, then they hone it to perfectly round again at the original factory diameter. To do the wrist pin end (small end) they ream the hole and press in bushings that also bring the hole to original factory specs.

We're talking thousandths of an inch here.

The reason for doing it is because the strains on those components are largely "linear" along the rod so the holes tend to get slightly elongated along the long axis of the rod - again, thousandths of an inch but that's what you're dealing with in an engine - precision really counts towards power and longevity. That's why they call it "blueprinting".

Re: $6,600 to rebuild Atomic 4? replace/rebuild

Well, I thought I would just close the loop on this thread and give a quick update...

I am very happy with my decision to take on the project. The money I saved is not even close to the enjoyment/education I gained from the job. It was not without it's fair share of bumps and curve balls, but I am happy to say that the motor is back in the boat and has been running better than ever. I happened to run into the mechanic during my (delayed) launch and he complimented me on the reassembly...I told him Moyer did it.

Thanks for all the feedback and insight, couldn't have done it without ya!

Chris

My Atomic 3 or 4 and the Moyer forums have taught me a lot about wrenching my own engine.
Glad you enjoyed the trip!

Re: $6,600 to rebuild Atomic 4? replace/rebuild

You should talk to Don Moyer at Moyer Marine. If you call him up and speak to him directly you are likely to get a fair answer and price. He has given me excellent free and unbiased advice in the past and his company is the reason why I am keeping my A4 and am not repowering. I somehow never trust boat yards.
