the bearing on clutch that when it comes offs the tiny little pins go eveeywhere so i order another with pins but question is there one that works here without pins? like some normal bearing?  is it easy to find these pins ? hopefully i dont spill new one.  pins might of gone in case or flywheel i really got to figure our where they went but ordered a new one so i think theres like 7 pins and i lost 3.  
thanks

picture or 5 would be nice.
Hope its not from the blind bearing in the transmission.
Also, measure those suckers !

ok i just opened mail and bearing i got is clipped together with pins inside and doesnt really look like it comes apart easy so maybe i was missing half of original or i think i ordered a 71 year bearing thing but other is 69. do you think there different or i just missed the retaning part on 69? i kinda afraid to pull it out bag to look better. it seems like i need this bearing style. anyhow this style i can install but is there anything new or like it that works good? i guess im good to go now clutch wise.
thanks

yeah i played with one i got and it seems stuck together. just wondering if older one you have to sandwhich like a crazy person or if i got given part without other part. its the little thin metal thing between case and back of clutch.

Pins--"little needle rollers"-- are not meant to escape out of their slots in the bearing. Bearing comes as two pieces with a washer as part of it. Here's a link showing No17. There's a kickstart gear not shown there but looks like the bearing goes needles against the big thick washer with bearing thin washer 'outwards' then kickstart gear so the thin washer protects the needles from the kick gear. For some reason i thought that bearing went on the other side of the clutch but ignore me as just thinking aloud. Second link shows No29 the kick gear i mentioned. You must be VERY careful that the bearing doesn't get trapped behind the spacer it sits on while assembling the clutch & clutch hub, as can move put a little if not careful & bearing gets trapped behind damaging it. I think later motors did away with the bearing & just spaced it up with a thick washer or totally changed the design.

YEP, #17.

 

 My ‘71 dt1e has same type of roller thrust bearing which I totally destroyed by crimping by not being careful while assembling. And of course I became confused when ordering until I realized that the part number included the thrust bearing with needles itself and a thrust washer that serves as one of the two bearing surfaces upon which the rollers roll. I found one on eBay luckily, very cool design detail vs a thick flat washer only 

 

Oh and to be clear one cause of my confusion if I recall was that the solid washer that came with the needle bearing was not shown on partzilla pics. Washer 18 which doesn’t come with bearing completes the sandwich that has needle thing sandwiched between 18 and the plain thrust washer that came with needle bearing part 17 Oh and to be clear one cause of my confusion if I recall was that the solid washer that came with the needle bearing was not shown on partzilla pics.
