REF 14 Tools and Workshop Tips the joint will be held evenly and will not be distorted Important joints such as the cylinder head and big end fasteners often have two or three stage torque settings Applying leverage Use tools at the correct angle Position a socket wrench or spanner on the bolt nut so that you pull it towards you when loosening If this can t be done push the spanner without curling your fingers around it see illustration 4 6 the spanner may slip or the fastener loosen suddenly resulting in your fingers being crushed against a component The same equipment can be used to install bearings Make sure the bearing housing is supported on wood blocks and line up the bearing in its housing Ht the bearing as noted on removal generally they are installed with their marked side facing outwards Tap the bearing squarely Into its housing using a driver or socket which bears only on the bearing s outer race contact with the bearing balls rollers or inner race will destroy it see illustrations 5 1 and 5 2 Check that the bearing inner race and balls rollers rotate freely Caution Ensure that the puller s centre bolt locates securely against the end of the shaft and will not slip when pressure is applied Also ensure that puller does not damage the shaft end 5 4 Where no access is available to the rear of the bearing it is sometimes possible to draw off the adjacent component 4 6 If you can t pull on the spanner to loosen a fastener push with your hand open Additional leverage is gained by extending the length of the lever The best way to do this is to use a breaker bar instead of the regular length tool or to slip a length of tubing over the end of the spanner or socket wrench If additional leverage will not work the fastener head is either damaged or firmly corroded in place see Fasteners off a gear shaft for example you may have to locate the puller behind a gear pinion if there is no access to the race and draw the gear pinion off the shaft as well see illustration 5 4 5 1 Using a bearing driver against the bearing s outer race Operate the puller so that its centre bolt exerts pressure on the shaft end and draws the bearing off the shaft When installing the bearing on the shaft tap only on the bearing s inner race contact with the balls rollers or outer race with destroy the bearing Use a socket or length of tubing as a drift which fits over the shaft end see illustration 5 5 5 Bearings Bearing removal and installation Drivers and sockets Before removing a bearing always inspect the casing to see which way it must be driven out some casings will have retaining plates or a cast step Also check for any identifying markings on the bearing and if installed to a certain depth measure this at this stage Some roller bearings are sealed on one side take note of the original fitted position Bearings can be driven out of a casing using a bearing driver tool with the correct size head or a socket of the correct diameter Select the driver head or socket so that it contacts the outer race of the bearing not the balls rollers or inner race Always support the casing around the bearing housing with wood blocks otherwise there is a risk of fracture The bearing is driven out with a few blows on the driver or socket from a heavy mallet Unless access is severely restricted as with wheel bearings a pin punch is not recommended unless it is moved around the bearing to keep it square in its housing 5 2 Using a large socket against the bearing s outer race Pullers and slide hammers Where a bearing is pressed on a shaft a puller will be required to extract it see illustration 5 3 Make sure that the puller clamp or legs fit securely behind the bearing and are unlikely to slip out If pulling a bearing 5 5 When installing a bearing on a shaft use a piece of tubing which bears only on the bearing s inner race 5 3 This bearing puller clamps behind the bearing and pressure is applied to the shaft end to draw the bearing off Where a bearing locates in a blind hole in a casing it cannot be driven or pulled out as described above A slide hammer with knifeedged bearing puller attachment will be required The puller attachment passes through the bearing and when tightened expands to fit firmly behind the bearing see illustration 5 6 By operating the slide hammer part of the tool the bearing is jarred out of its housing see illustration 5 7 It is possible if the bearing is of reasonable weight for it to drop out of its housing if the casing is heated as described opposite If this
