By: Overhauling Rear Drive
These notes cover all rear drives after chassis number 65186, but the procedures for the overhaul are similar. Before starting this job, do some diagnostic work to determine the extent of repairs and replacement parts needed. Jack up the car and make it secure and remove the wheel and brake drum to reveal the brake linings. You should plan to replace these anyway as most of the work you do in dismantling the rear drive must be repeated if the rear brakes are to be replaced. If the brake shoes are covered in oil then the rear seal must be replaced. Take off the rear chain cover, taking care not to damage the synthetic rubber gasket that is normally re-usable. If there is corrosion present, you should plan to replace the chain and the rear axle bearings. Remove the small oblong cover at the front end of the chain case again taking care with the synthetic rubber gasket. Check for corrosion around the small chain wheel and pinion, if none is present, it is usually safe to assume the front bearings are in good condition. If you are not sure, it is better to remove the complete rear drive from the rear frame by releasing the eight bolts from the rear suspension rubbers. Once you have dismantled the rear drive the car is not moveable and if this is important to you, then plan to have all the parts and tools available to complete the overhaul.
Silicone use and Applications
The article by Anders Johnsson the Engineer from Sweden, on "Silicone - Carbon Brush Poison !" featured in the July 2001 Edition of Kabinews was excellent in it's content and the problems that it highlighted. Having shown the article to a number of people, it created quite a lot of interest, especially among my well qualified and experienced engineering friends and colleagues. They come from a variety of disciplines both electronic, electrical and mechanical, and the notes below contain a summary of information that we are all agree on. In the real world, of the local garage, motor factor, DIY store or builders merchant, there can be found on the shelves, many items known generally as "Silicone Sealants". In this guise they are often sold to be used for engine / machine joint sealants, bath sealants, window sealants both for windscreen rubber repair and for where bonding is required to brickwork etc.
