How to Replacing Rear Main Seal 1

The next day I woke up early and drank lots of coffee before going out to the garage. I knew I had two distinct problems confronting me. First, I would have to purchase an impact tool in order to loosen the six bolts holding the clutch together. Also, I would have to purchase at least three 8mm by 50mm bolts and nuts in order to prevent the clutch from exploding when the six bolts were unscrewed. For the third time in two days, I went to Sears and asked the salesman, (who I now I knew as Art,) where I could find an impact tool. He did not know what it was I was looking for, but he asked another employee and soon I had the tool as well as a 6mm Allen socket. Unfortunately, the Allen socket only came in 3/8″ drive, and the impact tool only came in 1/2″ drive. Thinking quickly, I purchased a 1/2″ to 3/8″ adapter, as well as a 3lb. dead- blow hammer. On the way home, I stopped at a Chief Auto Parts to buy the bolts I would need. The closest size they had were 8mm by 40mm, which was nearly 10mm too short. I was unsure whether the clutch cover bolts were coarse thread or fine thread, so I bought three of each, along with corresponding nuts. Finally, around 11 o’clock in the morning, I was back at the garage ready to work. I prepared the impact tool and placed the adapter and the Allen socket on it. I began to hammer on the end of the tool, trying to loosen each of the six bolts. None of them seemed to move, even though it seemed the impact tool was turning. Finally, I put the Allen socket on the breaker bar and found that all of the bolts had actually come loose. The tension from the clutch spring made it nearly impossible to see, however. I removed three of the bolts in a triangular pattern. Into these empty holes I threaded the fine- thread 40mm bolts with nuts attached and tightened them evenly. I was now able to remove the remaining Allen bolts. By slowly turning and loosening the nuts evenly on the 40mm bolts, I relieved the pressure from the clutch spring until the cover plate was free. I removed the cover plate, the clutch, the pressure plate, and finally the clutch spring. I had already marked each of the elements with Whiteout to insure that they would fit together the same way on installation. Apparently, this is essential as the flywheel could be rendered out-of-balance if the clutch components are not installed correctly. The flywheel itself was now exposed. I could see the five bolts that attached it to the crankshaft. I now used a tool I had fabricated. Although the manual describes two possible tools that can be fabricated, I found a piece of metal that resembled the tool and decided to use it. Unfortunately it was not strong enough and broke. I turned and looked at my workbench, and noticed a bracket which I had previously fabricated for mounting a mirror on my Vespa. The piece of steel was extremely strong and was already pre-drilled with correct-sized holes. It fit perfectly, so I placed it over the exposed bolt which protruded from the case, and placed the other end on one of the 40mm bolts, which I then bolted into the flywheel itself. I used the breaker bar again and removed the five bolts. The flywheel came loose after inserting two more 40mm bolts and tugging on them evenly
