Hi All, This seal is leaking (2005 engine). If I remove the sprocket and 2 circlips can I remove the seal easily and replace with a new one? Any practical tips would be much appreciated.

Yeah you can.

I'd recommend cleaning the shaft up really well before removing the seal, if necessary use some emery cloth to remove any rust.

Before putting the new seal on wrap the end of the shaft with insulation tape to prevent the seal snagging and smear some grease on the sealing surface of the seal.

Thanks TNMan, It was easy and took about 5 mins.
