    BBSHD grinding resistance

    I recently ordered a new BBSHD and buggered up the retention spring that holds the pawls in place when installing the Lekkie Motor Cover. I removed the pawls altogether and continued mocking the bike up. Once complete (and without a working clutch) I took it for a test run on throttle power only. Worked awesome. I hit 31-32MPH on flats and 18MPH-24MPH up hills.

    I went ahead and ordered another BBSHD and asked if they would go ahead and throw the Lekkie Motor Cover on it for me. They did. I just took out the first motor and installed the second motor. The problem is, I get massive resistance - even a grinding noise - when manually cranking by hand (the bike is in the air on a bike stand). The thing just does not want to spin freely. There is no way this is okay. Kind of bummed that I dropped an extra $1000 on a second motor and it showed up like this.

    Wondering what the heck went wrong here? The Lekkie Motor Plate appears to be seated well. Guess I need to crack this one apart too?

    Any suggestions? With the Pawls in on the clutch, should the cranks freewheel backwards with gravity? Meaning, if I hold up the cranks and drop them, should they fall back on their own?

    If the cranks are balanced they shouldn't turn on their own at all from gravity

    OTOH I have an extender on one side that makes it heavier enough that it will readily freewheel backwards due to the extra weight

      We have read some reports here of BBSHD's being kinda stiff to start with but after a couple miles seem to loosen up. On a forum its hard to judge how stiff these things are. When all is well there is more resistance going forward than there would be on a normal crank set but its not so massive that you think its gonna be a problem. I remember kinda wondering but then thought oh well there is likely a lot more drag from all the extra weight than this little extra in the pedals. Mine I can easily pedal it in the stand with one finger assuming the wheel is already turning or not in a high gear.

      I have not installed or messed with the Lekkie cover on a HD so I don't know if there are easy places to make mistakes. I assume you have to press the bearing and gear out of the old cover and into the new one? Maybe its not pressed in all the way? I did a lube job on a 02 with one but that is a different setup. The 02 one appeared to be a high quality piece. Same opinion on my 42t blink ring. I got a lot of miles on mine and its still working great.

      You can buy that pawl hub assembly as a replacement part if you damaged or lost the parts. It seems to usually be called a clutch assembly. At the moment Luna appears to have stock $25.
