Derbi PP loose needle rollers wanted

todd amundson /

There are to wide needle bearings in the case. When rebuilding, I found most of the needles floating around in the case. The ones I was able to collect show that they passed through gears and got thrashed. I need new ones to load back in the cages for reassembly. Anyone know sizing on these?

Also the pedal chain in there snapped. Anyone know the chain size so that I may install a masterlink to get it reattached?

Looks like 35???

I think the tomos chain is the same pitch, but you might have to make it the right length. Also you may want to try to find a couple replacements for those roller bearings if you can. They look pretty crusty.

Measure the ID-OD and width of those needle bearings and order the whole thing. If the rollers have fallen out they're toast. The bearing number may be in the parts manual, but I don't have access to that.

ID 16mm OD 19.6mm W 43.5mm

Yeah those don’t exist. I’m probably going to bore out the main gear to take a 16mm ID drawn cup bearings or two. Then use my existing needles for the rear input shaft. How’s this chain going? Many of the 37 links are cracked.
