 |
| Piss-poor original sintered copper sleeve bearing |
 |
| Luckily the original design was for a deep groove ball bearing 8x22x7 a.k.a. 608 |
 |
| Unfortunately the bearing position has not been finishing machined. |
 |
| The machining reserves in the diameter are around 1mm. |
 |
| The lip is in the righ diameter but the insides are a bit too tight |
 |
| After some dremeling later the pocket is big enough to accept the 608 bearing |
