| REAR TOGGLE SHAFT. BEARING. (We have no drg. of this so it may be out of proportion) Two small drain pipes become choked with dirt as shewn, if the casting is carried on as per dotted lines and drilled with the hole looking backwards - no tube would be necessary. We have sweated longer tubes on to existing ones. Draintube for centre housing is too short, and hole too near brake drum. Dirt & water rebound off guard and enters hole. | ||
