ACR question

clint larson · #1 05-11-2016, 10:27 AM

Been chasing a hard starting problem on my 100 (k241) , I am now checking acr and when I removed the cam plate (guessing to see a spring broke, but they were both there) and trying to figure out how they work when it hit me that the weights are on the wrong side, they are on the front side of the ring gear not on the lobe side. I have never looked at one of these before so can someone confirm that some moron put them on the wrong side or am I the moron cause I yet don't understand how it works. All the pics I found of them on this site show them on the lobe side, and I can not even reason how they would work like they are now. If they are on wrong side is it a matter of taking them off and putting them on other side? Can they be switched by dropping the pan or does the cam have to come out? Attached is a pic but hard to see anything. Thanks clint

Your picture sucks so I am not sure I even understand your question, but here are some pictures of a Kohler cam with ACR. As far as how it works, the little square nub (highlighted in red) holds the exhaust valve open a little bit at cranking speed to relieve compression. When it starts, centrifical force flings that arm out of the way and lets the cam lobe open the valve normally. The spring is there to counter act centrifical force and hold the ACR in until it starts. I don't have a clue how anyone could put any parts on the wrong side of the gear as you are decribing. Hope the pictures help.

I would check the connections on the starting system. File,sand or somehow
clean all of them and try a new battery first. I wouldn't mess with the ACR
unless absolutely necessary

All right here is a better picture, you can see the weights on left side of ring gear ( left would be front of tractor). You can see the lobe on right side of ring gear, which is where I'm guessing the weights should be.

Better pic of right side.

As far as the hard starting goes, I've all ready, set new points (static method),New plug, good charged battery, checked/cleaned grounds, adjusted valves, rebuilt generator/ starter.

I just need to know if this acr system is correct or not right now, thanks clint
