Lucas slabber chain jumping
« on: June 12, 2018, 08:00:11 PM »
Iíve been having issues while slabbing when pushing the carriage in a cut thereís a vibration it sound like the chain is jumping the sprocket but it is not .I bought the 8/25 secondhand and have been replacing normal wear parts I have installed new style bar 14 tooth sprocket new drive belts all rollers gas strut.The gearbox has a leak but there does not seem to be any slack but that seems to be the area the noise is coming from. I have shimed the bar so it is plained level.

Are sprocket, bar and chain all the same? If you have the old bar maybe mount it and see if it goes away?

I have to assume you swapped out chains? I've had an aggressive chain jump around quite a bit.
Basic but helpful?

Hate to hear your having issues.  If you donít think its the gearbox, maybe check the belts and clutch, slippage there may cause the sound. Or not.  

Drain the gearbox and use a small magnet to collect any possible metal debris.  If none, it may be okay.

 I did replace the clutch I think it is the belts I tightened them up and it got better but I think I got them hot and they are jumping when I push into a cut they may have stretched when I retightened the muffler is almost touching the swingframe

I was talking to fishpharmer and Xlogger at the slab workshop about us smoking belts pretty easily. We overtensioned the first set and cracked them, it's easy to overtighten them. I think we went the other way with the new set and were afraid of too much tension and were running too slack.
