Code 3 XL inconsistent speeds

[OSP959(R)]

What causes the Code 3 XL to speed up and slow down? Tried hitting it with some WD-40, but it still does it. Any suggestions on making it run smoothly?

Which style of XL are we talking about the 9000 (Sealed beam) or the 5000 (independent rotator)?
The 9000 usually encounters this when there is not enough juice to power all the functions.. However I have also resolved this issue by cleaning and if needed replacing the rubber belts if they are worn. I have seen instances where a worn belt is rubbing and catching at points which slows that rotator down.

The sealed beam and belt style. it seems to speed up and slow down at a consistent rate.

Speaking of belts, can you even find these anymore??

Try cleaning the belts and the sprockets. Debris from the belts will clog up the sprocket gears. Toothbrush will do it, and actually you can let it run and hold the toothbrush steady for the belts.

Another thing to check is the sprocket pin. Make sure it is flush with the sprocket. If it sticks out either way that will cause a hiccup.

WD40 works great right up until it gets sticky. Will freeze up a gun action for example. Maybe clean and then some Break Free on the moving metal parts.

Like TDC said, WD-40 is good to free something, but once it is freed, you need some lube in there to keep it going.

I had the same issue with an XL bar a little while back, it turned out that the belts were so old that they began to dry out and where they passed over a sprocket they took that shape from sitting so long. When the bar was then powered up and run it appeared to slow down when those curved areas passed between the sprockets as they would not flex and straighten. Once I put new belts on that we're more pliable the issue went away.

I had rubber dust packed in around the shaft acting like a brake pad ,a little emery paper a presto shes ready to rock&roll. dried out and out of shape belts don't help either. but then again she is no spring chicken

I thought there was a tensioning pully that could be adjusted on these ??

there is a tension adjustment wheel, but if the belt is bent from time they tend to skip as they turn over the gears, give it a good cleaning. I've saved a few belts with some tranny fluid on a rag... just saying
