Thank you! I’m pretty sure i did that cup method the first go with a clear cup. It seemed right but something was leaking bad.

What is the brass threaded insert on the right side of my main seal upper casing? Can it leak? Maybe if the chain wore the end of the insert if it was loose?

My question really was,
Should i be able to insta the spacer by hand easily? Or should i need tools to take it off and put it on? I have see a puller, but i can spin my spacer ring on the crank by hand and pull it off the crankshaft with one finger. Is this normal?

Also it seemed that te ring war pushing too far onto the crank, the seal wear mark was Galway to the lip of the ring. Normal?
