oh, and regarding clips i reused the old ones on my engine and when test running it after the rebuild i ran it up to 8200rpm to really give it a blast and nothing fell off. i have since flown it 3 times and had quite a bit of ground running. When i removed the clips i was very careful and upon replacement they were not loose or anything. heres hopeing im ok!

I concur with everything you said Phillip.

If someone is comfortable with disassembling their engine then I agree it is worth a look inside when brand new to check for swarf, and in the case of the FS400 to maybe change the e-clips.

Let us not forget however, that the original impetus for this thread was that one of my link pins failed, not the e-clip. A shoulder broke away on one of the link pins, and the clip was still attached.

So, for anyone contemplating changing the e-clips on their new engine, just use caution when pryinig them off so that you do not snap a shoulder off of the link pin. [X(]

BTW: Olivier Rogeau has created a series of videos that shows the disassembly of the FS400. It is in French language but the images are what matters:

Here is Part 1, and then you can look for parts 2-17 as you go along:

I looked at all the videos. One thing I didn't see was the disassembly of the e-clips from the link pins.

I installed the new C-E-Circlips-Rotor Clips-Retaining Rings tonight.

I do not have a special tool, so I used a combination of a seal hook and a ball head socket screw driver. Three of the e-clips came off fairly easily. But one was a bit*h to get off. My hook kept slipping under pressure and I made a lot of scratch marks on the master rod. They look bad but are superficial and of no consequence. There is no way 3.3 or even 7 lbs is going to toss these clips!

I did notice that the old clips were slightly stretched. But then, these have been installed, removed, installed, and finally removed again.

Interestingly, from the photo's posted in this thread, not all clips used by Sanye are the same. Some clips from Sanye, are black phosphate coated. Some clips, like mine, look like they are stainless steel. I ordered black phosphate coated clips as replacements.

Well, I feel like it was a worthwhile preventative maintenance to perform. Thanks to Rev77 and his insight. Although, Phillip, I did not recall that you had lots of local fellows having their clips fall off. [X(]

The weather in my area has been brutally hot, for what seems like months now. We are supposed to finally get some cooling over the next few days and I hope to get my FS400 mounted and tested with the new Rogeau Intake Manifold (RIM) during this time.

My wife loves it when I work on the dining table.



The motor opened up, the stock clips stayed in place during all those video taped runs a couple of years ago:



This clip was a beeee-yatch!! [:@]



The tools:



Old and new e-clips:



Old clip is now slightly stretched:

Do you prefer the Black-finish steel rings than the Stainless steel rings (from McMaster)? which one is stronger or which do you recommend?.
Thanks

LMAO!!!

I had been given grief over that same thing for years. Then came the day that the head on her car's engine needed to be rebuilt. Coldest, windiest, wettest winter we've had for years and the shop/shed just would not get, nor stay warm. I told her I would do the messiest parts out there but when it came time for assembly I was going to throw a blanket and a board on the kitchen table. All went well, the car ran great and it was only a few days days instead of weeks that she had to drive one of "the land yachts" which she hates to drive.(my Explorer or one of the boys' Jeeps)


She was happy, I was happy and not a word since when I cover up the dining table and "play tools and stuff" or build.

jmmt: Technically, stainless steel is not quite as strong as plain steel. But I would not have any qualms about using SS inside the engine. I bought the black ones because it came in a order of 100 pieces versus the SS which was double the price and 1/4 as many pieces.

To be honest, the new black clips even LOOK tougher...

Anyways, I had 40 Minutes last night so I started piecing the engine together again. Three cylinders are on, two to go.

fwiw, If you are not a friend of decorative tatoos on your main conrod, you can use two wooden chopsticks to push the clips off. The sandblasted aluminium surface really scratches very easily.

Tom,

I know of at least four engines here in austria where one of these clips has come off on engines that had not been opened. All of them where SS btw. I still think that they are of inferior quality and if not enough care is taken assembling them, they will be so stressed that they may not be up to the job anymore.

Lets be honest, these Engines are not being assembled with tlc by engine specialists/enthusiasts as for example is done at AGC with the Laser engines but by some underpayed chinese bloke or girl who probably doesn't even know (or care) what this chunk of metal is for and is doing so for 12 hours a day.

To be honest, at the end of the day I would probably be yelling "zhū" at every ring while hammering it in with a large blunt mallet...

Tom, good pics showing the dimentional disparity of the stock vs. replacement e-clips.

I have a question about the intake gaskets. Since things do not always go well when I attempt them, what material would you use to replace intake gaskets that may be ripped or torn upon disassembly?

Hey frets24, I haven't been able to find that 80" Zero build forum. Please give me the link if you can. I can tell you that the engine is a very tight fit in the cowl though. I just may have to cut some holes to clear the valve covers.

oh joy of joys! my engine lives yet again! finished assembly, hooked everything up, two turns priming and she roared like before! Did take an hour longer than anticipated due to a lost cam follower. turned the whole bl00dy shop over looking for it. finally found it in the front casing o_O. Now the weekend can come

that hat: Its my lucky hat for maidens. I got it from my grandfather (and best friend) before he passed. used to be his motorcycle cap in the thirties. No maiden without it...
