sn Superjet 61x reassembly questions

[SharkB8]

I am reassembling my sn superjet and as a newbie I am in way over my head. My shop manual assumes I am a semi-competent mechanic, so it leaves a few questions unanswered.

So here they are. >

I am attaching a picture to indicate what I'm talking about - the colored lines are more for my benefit than yours (for example, I'm sure you could identify the ""starter"" in the picture) - with colors it will be apparent if I'm talking about the wrong item or area.

(1) Should I put grease around starter seal? (green) I would be using JSS's "silicone grease".

(2) Where should idle gear be greased? (light blue) (ps is the idler gear also called a bendix?)

(3) Should I put grease on the grommet shown? (red)

(4) Is the dowell pin on the left side absolutely needed? (purple) Don't the seven bolts keep it lined up enough? (I seem to have lost one of the dowell pins, and I don't have a yamaha dealer in my area, and I don't want to wait a whole week for one to arrive in the mail.)

(5) Should grease or 2 stroke oil or anything else be applied to the flywheel shaft / key? (orange)

(6) One of the shop manuals does say that 2 stroke oil should be applied to the shaft's bolt and bolt flange. (dark blue) Why would they recommend that? I would have thought that cleaning the bolt and putting some locktite would be a better idea.

(7) The spot where the idler gear inserts into.. (black) I thought I read that that is supposed to be a bearing, but mine appears to simply be a hole. I hope that's right. I can push the idler gear assembly into the hole and it seems to stay, but is there anything else that is supposed to hold it in place? I guess it does press against the cover after its on (spring, washer, etc) - maybe that's all that's needed.

Thanks............

1) Yes absolutely.
2) I've never greased mine but it couldn't hurt i dont suppose, just dont go crazy. Also, yes its also called a bendix
3) I always do. Good rule of thumb is grease any place there is rubber/metal contact
4) I have all mine in. That being said i dont see why it would be VITAL.
5) nah
6) I have no idea why that would be recommended...but i wouldnt locktite it either. I always just torque mine down, never had an issue
7) A bearing? ive never noticed that and/or i dont remember it.

Same as above.. Always grease starter seal, rubber grommets, etc. Just make sure the bendix is CLEAN and debris free. The bearing you referred is a bushing, and as long as it's snug and not worn out your good to go. Clean and torque the flywheel bolt to spec and you shouldn't have any trouble.

I believe the studs are primarily there to help hold/line up the gasket in place while you affix the cover. One word of caution...Ensure the bendix is in place before installing the flywheel. I do it backwards every time and have to pull the flywheel back off.

The dowel that inserts into the front flywheel cover is there for proper alignment of the bendix. slight binding can occur if it is not present.

the oil on the flywheel bolt, vs grease, vs anti seize, vs locktite is a large debate here.

Per John at JSS's recommendations on the bendix gear, soak the bendix in mineral spirits for a day or so working the action of the bendix to ensure a debris is removed, then let it dry completely. Then soak the bendix in any type engine oil (2 stroke, 4 stroke, car oil, doesn't matter) for about 1-2 days, again working the action so the oil soaks into all crevices. Remove and let all oil drip out and your ready to install the bendix.

I use JSS's ski grease on tons of components on my ski, including the grommet for the stator wires. I also use it on most gasket surfaces so that they peel off easily when being removed. Reduces a bunch of scraping of old gaskets.

Also, in the front cover, make sure the spring is installed in the front cover, followed by a tiny washer the same diameter as the spring. Then the larger washer goes on the front of the bendix (cover side). I once installed it on the rear of the bendix and my bendix rattled and chipped the teeth of my flywheel.

Great advice from every one of you. Thanks very much..

No problem at all. thats what this place is all about.
most of us have all been there before. staring at a pile of parts that was at one time our motor and thinking "WTF...i am so screwed"
hahaha its part of the fun though. and next time you ride it will be so satisfying knowing you built it.

That's weird. I'm pretty sure my motor has never been apart before, and the large washer is on the rear of the bendix, by the bushing that the whole assembly inserts into. The only washer on the "front" is the one where the bendix would touch the spring.
