Question about Makita 9901 3 inch x 21 inch Belt Sander with Dust Collection, 1246 SFPM, 6.7 Amps
Makita 9901--I want to replace the motor bearings (parts 39 and 43) and it appears the bearings are pressed onto the shaft and should be removed with the right size gear puller (is that right?). the pullers I have are too large to getunder the bearings to pull them off. Is there any way I can avoid having to buy a small bearing puller just for this one job? Also, what do I do with the rubber pins (parts 44 and 45) when I put the new bearings onto the shaft ( I don't know where they go but in the parts diagram it looks like they are installed with the bearings. Finally, what can I do to press the bearings back onto the shaft--a vise, a C clamp, a bar clamp, some other method? Thanks, Frank
Do you have a bearing splitter? If so I have used one and then gently tapped the end of the shaft to remove the bearing. The rubber pins fit into holes next to the bearing bore in the housing. You can use a vise and a soft hammer to tap the bearings on. Put the bearing on the vise and tap the opposite end of the shaft. You are on the right track for all these methods.
