Puch e50 bearing noises.

David McHugh /

I am thinking of purchasing a 1980 maxi located around the corner from me for $200.

It starts, idles, stops, and the tank is clean. The only thing wrong is a terrible noise. The best way I can describe it is that it sound like when you whistle with a blade of grass, sorta like a kazoo. I think it's a bearing noise, but I just want to know if it is more likely the big end bearing in the crank, or is this something that can only be known once disassembled. I have had five Puchs all with e50s, and I haven't run into this problem yet. Thanks!

What does the trans oil look like? When in doubt drop the motor and open it up.

Re: Puch e50 bearing noises.

is it a ZA or an e50?

Squeaky whistling is often a head leak, squealing may be dry trans or stuck clutchparts, binding bearings etc. Usually crank and bigend bearing fails have a very grindy sound, it's a chunky not smooth surface rolling and maybe rubbing sounds like rocks in a tubler or griding things dragging. squeaks are a rotating part contacting and rubbing a static part.

I don't have time to work on it until Sunday. Thanks for your response es. I'll post a video with it running.

could No trans oil, I had a hobbit with a bad trans side bearing once that made the noise you’re describing. Rebuilds are easy and fun on E50s if it’s the crank stock cranks are cheap and abundant. Given that It runs already sounds like a reasonable deal for 200!

It's possible. E50s are extremely easy. I rebuild all my engines, new crank and all - even when keeping it stock. Since I don't have time right now to work on it, It's the difference between riding it or parking it until I do. Plus I'm just curious.
