4th gear removal

• With the bearing and sleeve removed 4th gear & the syncro will simply lift off
• Inspect the dogs on 4th, they should be sharp if they look worn this gear will need changing
• Put the syncro on 4th and spin it on the gear to ascertain whether it feels like it will work
• You need to do this with both hands and apply pressure, you counter rotate
• Look at the syncro and inspect it should look sharp
• The windows on the syncros should be without wear
• When windows are worn on syncros it can make for difficult selection
• The windows are what the detents or shift plates move into
• Early Puntos use roller and springs
• Later Puntos use shift plates, much easier and less fiddly
• The earlier gear sets are coarser and wear less
• The job of the syncro is to slow the gear down during a gear shift
• Carefully remove the circlip that holds the 3-4 hub onto the layshaft
• A word of warning, the more times the circlip pliers jump off the clip, the harder it gets!
• You are now ready to remove the 3-4 hub
