When you have to remove the motor do you take the coolant sensor out of the motor or do you disconnect it at the wire harness? This is on a 400 Scrambler. Thanks.

 

The wire unplugs off of the sensor.Later.

 

When you go to re-install the connector, put a dab of silicone di-electric grease on the terminal, or inside the plug. This is available at any auto parts store. Do this to your plug wire also.

I'm still having heck getting the coolant sensor to unplug form the motor. Am I right in assuming that you take the little boot out and just unplug? Cause if so it will not come out. Please help. Thanks

 

You are talking about the wire that plugs into the brass sensor on the head right.

 

No the one that goes down into the water pump area just behind the flywheel.

 

Sorry man,never took mine apart maybe Bubba297 could help.Later.

 

I think the one you're talking about is for the stator. Sitting on the bike, looking down at your right foot, I think it's three wires entering the case just aft of the pull start. You either need to disconnect the wires up front and snake them along where they run on the left of the gas tank. The easier way (depending on how often you pull your flywheel) is to pull the flywheel, index mark where the mounting screws contact the stator, and take it free that way. The coolant temp is a single wire the plugs into a sensor on the left side of the head.

Sorry for the wrong nomenclature. Yeah I just traced the wires back to the plugs and disconnected the wires and took them out with the motor to take to the dealer. There was oil in the bottom of the case when I pulled the outer cover off around the bottom of the starter gear and flywheel. Going to take it to the dealer on tuesday to have it checked out. I think that I have a counter balancer seal out. It seemed to be an automotive type oil and I can't think of any other oil it could be. Thanks for all of your replys. Shawn.

 

Shawn, grab that cylinder when your dealer pulls it and send it to me. You have the best all around pipe you can buy on the bikes, and porting the cylinder will add another 8+ horsepower. It makes all the difference riding in the sand.Bubba
