Re: Stus-List Rebuild suggestions for Atomic IV
Inspect the side plates and their sealing surfaces. In particular, inspect the thickness of the metal rim that the side plates are fastened to. Raw water cooled AT4's can be subject to loss of material if they sat for a while and oxygen supported corrosion in that area. Dennis C.

Re: Stus-List Rebuild suggestions for Atomic IV
As a minimum I would suggest the following. All seals, bearings, rings (hone cylinders). Check the following for wear and correct as required valves and guides, crank journals, lifters, and camshaft. If you have the A4 I am sure you have heard on Moyer Marine. They have all partsand are the leading experts on that engine. Good luck. I would love to see the shoo class teachers face when your son brings in that engine.

Re: Stus-List Rebuild suggestions for Atomic IV
I strongly suggest going to http://www.moyermarine.com/. The forum there is extremely helpful with A4 issues and that is where you'll be getting the shop manual and parts.

The other items needed will be identified by the inspection & repair process. I. E.: cylinder wear = oversize rings, worn valve guides, bearing clearance checks (plastigauge). In a normal teardown bearings & rings are automatic because of the ease of replacement while everything is apart. But if you don't put many hours on anyhow and cost is an issue then something within spec, albeit worn a bit, could still provide a dozen more years of service. cheers, Russ Sweet 35 mk-1 At 12:19 PM 10/10/2015, you wrote: Content-Type: multipart/alternative; boundary="=_Part_1817076_1012849173.1444504755751" Content-Length: 2460 We are pulling the A4 from our C&C 30 '73 tomorrow and my son is going to work on it over the winter for his term project in auto shop class.
