Kuhn knight slinger spreader

Bradiniowa · Mar 4, 2016

Anyone have experience and advice on the slinger spreader repair? Mine is a 8114. Need to replace the thrust washers to get the chains back in line. Been trying everything I can think of to get the sprockets off with no luck at all. They are on a splined 3 inch shaft. Tried a huge puller and a 20 jack plus a lot of heat and penetrating oil. Any suggestions?

Heat and candle wax, as it cools.

Had to have a welding shop do one. He heated with torch and got it really hot than cooled it with water right away. Than he used a monster air hammer to drive it off.

Hi like somebody else said heat and cold water. I used to work for an old blacksmith. No end of this stuff guys couldn't move would come in. He would heat cherry red put the hose on it with cold water. Get it totally cold hit it a few times with a hammer or turn threads with a wrench with some oil added and Bobs your uncle it was apart.
I have been doing it about 26 years I guess now with lots of different machine parts. remember it has to be stone cold as if not you run the risk of the part contracting to the shaft part way through and it galling up so you can't move it.
A buddy did that with a stuck back hoe pin that wasn't cold. I can say quite a few un polite words as to how hard it was to finally beat it out with a big punch and 14lb sledge to get the ram off.
I bet if you get it hot cool it and get the big puler back on it will come off. I have had the odd thing it needed doing twice.
Regards Robert
