My Dec 2020 build of a Dillenger Off-Road rear hub drive kit went well. The only hiccup was that my bike couldn't run in 9th (highest, smallest) gear without constant skipping under pedal load. All 8 other gears were zero problem. So, I've ridden mostly in the 8th gear. The Dillenger rear drive kit requires a Freewheel. I bought one from Dillenger when I ordered my kit, because my donor bike used a 9-speed Cassette.
I consulted a couple of bike shops and various fixes were attempted - first, we adjusted the rear derailleur, no good. Then we alligned the derailleur hanger. Nope. Finally we replaced the 9-speed chain. Still no joy.
So, the other day I ordered a new SunRace 9-speed freewheel to replace the 9-speed SunRace that Dillenger provided. Today, I screwed it on no problem... but wait, when tightened on the hub the Freewheel binds and will not hardly spin at all. If I loosen the freewheel it spins normally. But as soon as it's tightened in place it will barely spin at all and only with a lot of effort.
To keep riding, I put the old Dillenger supplied SunRace 9-speed freewheel back on the bike and it rides great - as long as it's not put into 9th gear. Because it still skips constantly with every push on the cranks.
Any idea of why: 1)it would skip in 9th gear only after all the changes we made and 2) why the new freewheel binds when screwed down normally?
