I've been chasing this problem for upwards of two years. Yeah ... I don't want to inform you on all the things I tried. But rather the symptom and the solution. Standard G310 from Grin, CA3, baserunner. Installed on old mountain bike. Ran really well for a couple of years. Even hauled a...

Thanks for the picture. I was able to source a replacement clutch from Grin (not on their website but is available) for a reasonable cost. Replacement was easier than I had feared. The clutch is held into place with a spring steel wire clip. The holes (that hold shear pins) are just big...

Hi, I'm strongly suspicious that the clutch on my G310 needs servicing. I have very intermittent behaviour. The clutch seems to be integrated in the outer body of the motor. Has anyone either serviced or replaced the clutch? Or do I have to buy a replacement? Thanks, Mike

Hi, I was exploring the lubrication of my freehub on a G310. The lock nuts were not particularly tight. Easily spun off. With them removed, it was easy to add some oil (used Phil Woods Tenancious Oil; it was handy). Setting up the locknuts wasn't so straightforward though. The lower lock...

Logging an update here, just in case it helps someone else. Justin at Grin got back to me. Suggested that I check the third screen on the CA. If 0 rpm pedalling forwards but actual if pedalling backwards, then try switching the polarity. I did this and there is now some response from the...

Hi again, I just read that if the CA doesn't sense Cadence (hence the Start Threshold and Stop Threshold), it won't kick in. I see the P and D arrows move. I'm using the CA defaults of Start Threshold (0.3s) and Stop Threshold (0.2s) per pole. Tried different Assist Scale Factors, if that...

Hi, I've never managed to get the CA to register any human Watts. It is a rear geared motor G310, CA3.1, and Baserunner controller. All components from Grin. Tried multiple times to get PAS/Torque mode to work with SEMPU BB. Varied all kinds of settings and thresholds. The SEMPU BB seems...
