Stator removal from rear housing

Post by Saltspringer » Tue Jan 14, 2020 9:29 pm



I now have two GL1000 engines on my bench; a higher mileage, slightly smokey, example with an as-yet undiagnosed rattle, and a lower mileage GL1000 replacement.

I am carefully taking the high mileage example apart to get to know my way around the engine, everything I remove I will inspect and carefully store away as spares. In the lower mileage engine I am planning to replace the primary chain tensioner, stator, and water pump, before refitting in my 1976 frame.

The question I have is how do you physically remove the stator ring from the rear engine housing? I have taken out the three securing bolts and assume that the actual stator it is an interference fit onto the housing.


I don't want to get too physical with it and damage something, is there a trick to freeing it off without bending or cracking something? I need to take it out because the wiring insulation has cracked where it exits the casing, in the black plastic plug. I believe that there may have been a short here. The white wiring loom plug is melted at one terminal and I had to break it apart to separate the wiring when I removed the engine. Can I assume the stator survived this short? I will cut and remove this plug when the bike is being put back together...


Any advice is much appreciated!

The Stator itself looks brand-new, it has most certainly survived. Otherwise you'd be seeing black crispy-looking shellac on the windings on some or all of the stator poles.

It is an interference fit, keep at it and it will eventually come off....

As to the cracked wire insulation at the housing feed-thru, it doesn't appear to have shorted there, you could fix that easily with some heat-shrink tubing and maybe a little dab of JB Weld or epoxy. I wouldn't waste that stator. The melted connector attaching the stator to the loom is a common failure point, best thing to do with that is cut the connectors off and solder the three wires when you put engine beck in the frame. Doesn't matter which yellow wire from the stator goes to which from the loom.

Thanks DenverWinger, I thought that this stator looked good too!

It is better looking than the high mileage engine stator, which has a distinctly browner overall coloration, although it worked just fine when the bike was running. Glad to hear that there the stator is an interference fit and I just need to be gently persistent....

Wiring repairs are pretty easy to do and I will find a solid wire-to-wire alternative to the fried plug.

Thanks for taking the time to share your advice; appreciated.

Test that stator before you put it back in the bike. A burnt connector and those wires show signs of high heat indicators of a problem.

You may need to get under the stator to gently pry it away from the rear case. A small carpenter's pry bar will do the job.

Great advice, thank you!

I am reluctant to start yarding on stuff without knowing there is not some hidden snap ring somewhere!
