Using this Draper 59123 kit is easy. First, identify the bearing, seal, or bush you need to insert or extract. Select the appropriate adaptor ring from the 22 available ones. Attach it to the part and then use the fine - thread puller bar with the thrust - bearing hex nut end to perform the insertion or extraction process. Make sure to apply force evenly for a smooth operation. When using the kit, avoid using excessive force as it may damage the parts. Also, keep the kit clean and dry. After each use, wipe down the adaptor rings and puller bars with a clean cloth. Store the kit in the provided blow - mould carrying case to protect it from dust and damage.
