Oil seal info

[Lucky Phil]

Came across an interesting fact about seals today that might be worth remembering Some modern oil seals are made from PTFE and must be installed dry. They rely on transferring some of the seal material to the shaft in the initial running so its a PTFE against PTFE situation. If you install them with lubricant they will leak within a few hours running. Don't think its applicable to older Guzzi's but worth bearing in mind for modern applications. If the install procedures dont specify some grease on the seal then assemble dry.
