Old fire sparked by rolling chassis

[Czekus21]

Well. I assembled the final drive assembly to mount the rear wheel to make a rolling chassis. (Had to do some work to my Jeep and needed the garage space). After I was done with the Jeep and looking at the SG sitting in the front yard, I decided to split the engine case. Well, I wish I had a camera to upload some pics. About an 1/8th in layer of metal powder lay in the transmission pan, The oil pump screen was caked to much there couldn't have been any oil flow, Found a piece of roller bearing skeleton laying amongst the powdery goop. The kicker? Missing three (yes 3) crank bushings. As far as I'm concerned, With what I was told from the guy I bought this bike from, (He said he had it running and it ran great) I feel that I paid about $400.00 too much. That's ok though. As with any project, tools are needed. Bought out of necessity. Welders, air compressors, etc. Now the question of the day. I need a lead on complete gasket kits, seals, bushings, bearings etc. I looked at Parts and more and put together a Cart. No bushings/bearings for the crank. Any leads would be appreciated.
Maybe this beast will be running again under my watch after all.

If you have crank bearings wiped out and spun in the case the case and the crankshat are probably no good.

As many parts as you may need to fix what you have described as major damage I'd look for a full engine on Ebay. If you buy all the parts I think you will find bad in there buying parts could be much more than an engine complete or at least the crank case complete. I worry when I see metal being pumped threw an engine. I'd have to take it all appart just to clean it.

+1 on that. Cheaper to get another motor....

I think that I may break out some tools that I've all but forgot about. Plasti-gauge and micrometer. Haven't used them in along time (about 25 years).

You need to break out the tire mounting tool and beat the guy who sold you the bike about the head and shoulders.

Hey Charles,

I know playing with the "toys" can be fun, but like you said, tons of metal shavings....don't forget that the cam journals are ground into the case/head, they may also be badly scored as well.....would have to get a new head then anyways. I, too, vote for a new used engine that you could better invest the $ into and have one that you would then know it's condition, and have one that will last.

I in no way have doubpt that with time and moneyyou can repair the engine. You may be lucky and not have much damage. Personally my main concern would always be did I miss some of that metal. If its locked in an oil passage, under a gear, or just stuck to the case. I know I would worry all the time every time a noise changed.

If you do rebuild for your peace of mind pull that thing all the way appart and put all parts threw a good cleaning and blow and clean out all passages. With cars I always had blocks boiled out for this reason however alluminum cases and parts don't survive acid baths so they need more effort cleaning.

Given how nice the guy who sold it to you and said how great it ran for him you may want to save some of the metal sludge and bake that nice guy a cake. If that stuff made the bike run well imagine what a little of it could do for him.
