stefan Posted January 11, 2004 Report Share Posted January 11, 2004 Hi, after mounting a new timing chain my TLR 200 has a huge base engine knocking noise What I did: Changed the timing chain cleaned out the centrifugal oil filter on the right side After the rebuild refilled with oil, started the unit and: the noise from the chain slack was gone but a huge knocking noise from the bottom end came on. The noise is in sync with engine speed and does not fade away like after the refill of a dry engine. Sounds like an engine w/o oil pressure What I checked again: Timing: OK crankshaft bounce ( in case I bent the crank while blocking it to get the rotor nut out) 0.1 mm on rotor: OK gears I blocked with a mild steel piece: No bent/broken teeth centrifugal filter: Initially found a lot of debris in there (the previous chain already grinded away a rib near the lower sprocket) housing: no chafing marks Any idea?

the artist formerly known as ish Posted January 28, 2004 Report Share Posted January 28, 2004 Was the chain good and tight to get on, I put one on my bike and the part number was right but it was too sloppy, put a DID one on it was a little harder to get on but once on worked much better. If the noise wasn't there before chances are what you have changed is the problem, I'm thinking timing may be a bit off, or oil passage blocked.
