It is very important not to rush, pull everything apart and throw away the old bearings. Clean up the remaining parts and fit the new ones carefully, taking note of the important points listed below, read the instructions. F0193 Evo Solid Downtube Manual Page 4 of 7 25/09/2006
The bearings in the back joint are small and the balls in them are delicate, each time you go to hit the bearing think first The force of the hit must never travel through the balls. When you are fitting bearings to the back joint hit the outer rim of the bearing only. (illus 2.) If you do hit the wrong rim or the seal of the bearing it will distort the balls. Do not use this bearing, it will run hot and wear quickly. Throw it away and use a new bearing. Never reuse old bearings, the bearings will have been damaged during removal. Always replace both bearings in the back joint. Do not use a steel hammer as this will jar and damage the tools and bearings. Use a nylon hammer or a piece of wood. Use a Special Tool Kit, they are not expensive and will last a lifetime. Use a small piece of hard wood to work on as a bench. 10.1 Remove the short tube from the downtube. 10.2 Unscrew the bottom tube joint spindle from the cog and remove from the back joint. 10.3 Unscrew the ferrule from the top of the back joint and slide back, unscrew the top joint spindle from the cog and pull the back joint away from the downtube. 10.4 Remove the back joint spring and caps. The back half joints will now come apart. 10.5 Slide the punch C through the back half joint at the threaded end and holding the back half joint in your hand gently hit the punch to knock out the old bearing. (illus 3.) Clean the back half joint thoroughly. 10.6 Place the back half joint thread down on a piece of wood, gently tap the new bearing into place using tool A (illus 4.) 10.7 Repeat this process with the other back half joint. 10.8 Reassemble the back joint using new grease in the caps. 10.9 Reassemble the downtube oiling the joint spindles and cogs.
