When you're over next, I'll show you the roller rod bearings on my old TS100.

Usually you only see roller bearings in the bottom ends of 2 cycle engines, how else would the fuel-oil mix suspended in air lube the bearings? (*think* roller bearings, or ball bearings, will not hold oil under pressure worth crap, to lube the rest of the engine)
The "Usual" for 4 stroke engines is a a "plain" bearing, or a "babbitt" bearing: http://en.wikipedia.org/wiki/Babbitt_%28metal%29 The main feature is this bearing will hold oil pressure and allows the entire engine to be lubricated with a single, simple, oil pump. Some hybrids do exist, but they are few, and far between, and certainly not in most of our price range. |
I don't believe the rod is removable from the crank on these engines.
You have to buy it as a unit. http://cgi.ebay.com/ebaymotors/ws/eB...d=330428766733 Sounds like you just need a new crankshaft and piston rod. |

You'd have a bitch of a time pushing that crank back together unless you have a fixture and a big arse press. Or have a buddy with a motorcycle machine shop. I don't think a 30lb sledge is a good option on these. |

Check around in the old Yellow Pages, you might find someone that can press it back together...otherwise, I'd save up for a complete motor. JMHO, Bill R |
I would vote on the complete motor too. I looked further and found a crank/rod for $50.
|
oh i measured from the wrong spot. i def have a short motor. i bid on one on ebay

KZ Kawasaki motorcycles (900, 1000, 1100) have a roller bearing crank. The oil pump is high volume low pressure, when adding a turbo you have to add an electric oil pump and separate oil supply. |
