My KA2 is not getting very hot. So here is the situation. I run it all year for water. I had it shut down for a number of weeks this summer while away and before start up did a good cleaning. Started it up in October for hot water and everything was normal and working fine.
This week I decided to turn on the radiant floor heat so I turned on the circulator pumps. Added the extra pins in the timer, I remove some for Summer, and increased the feed rate. Now it usually takes a while for all the water in the loops to come up to temp. But it has not happened yet. The boiler is limping along at about 130F.
*This morning I was looking everything over and I noticed that the feed mechanism,the pusher bar, is not moving very far back and forth?
Need your help!!
Thanks!
Took my stoker apart!

I think these stokers use a plastic cam to move the feed mechanism? Could be worn, or something could be binding. Sounds like you need to shut down for a cleaning and inspection.

Rob is right, this stoker should be one that is driven by a plastic cam. If you don't see anything else obviously loose, it's probably time to replace it.
The plastic cam and side screws are an over-fire safety device. If the fire gets to hot, they melt causing the stoker to push less coal. You should keep a spare cam and screws on hand so when this happens on a weekend you don't have to wait for Keystoker to open on Monday to get new ones.

Did you get a new cam and a spare?
I merged this with your post about the stoker not pushing enough. No need to have 2 threads about the same problem.

Good! Now I am curious, if it's not the cam, what is it?
