REBUILD TIME! First timer has some questions.
Alright, most of the internals look good except ive got a few strange things going on. I will put up pics later as my buddy's camera is too complex for me to get any fine detail.
First, the e-shaft has burn marks around it. There are two rings one on both sides of the shaft where the lobes that the rotors ride on meet the twist in the middle. Second, the front iron is not in spec- there is a pretty deep groove that my fingernail can catch on so im wondering what to do about it... Should I send it off to get lapped? Should I replace the iron? If I replace it should I replace the rear iron at the same time just so everything is even? Finally, what constitutes a bad bearing? I see no copper on my rotor bearings but on one of them it looks like a piece of metal got in there and scored it up a little (however there is no such scoring on the e-shaft?). Also what do you recommend I use to clean all of these parts? Can I use just about anything or are there things I should avoid that would damage the surface on the rotor housings? Pics will be up a little later. |

For things like the eccentric shaft, stationary gears, oil pump and chain, etc. I just use brake cleaner to hose them down. |
The marks on the eshaft are from the heat treating process.

basically, anything u can catch ur finger on, get it replaced. like for the irons, yeah.. lapping works but id rather get a good condition iron.

The only thing that compares to a resurfaced iron is a new one. If your fingernail catches it imagine what it's doing to your engine at 7k. Get it resurfaced whether it be lapping or grinding. I never build an engine without resurfacing the irons. Of course, I do my own so it's cost effective. You should be able to get all 3 irons done for $200-$300. Considering the time and effort that goes into a build it's well worth it.
