What is the replacement procedure for the seal and does it need lubricating when inserted? If so, what type of lubrication? Thanks?
This part does not include installation replacement instructions but you may find this info in a service manual for your engine. If you do not have a service manual, you may view them on our site here: As for lubricant, the manufacture doesn't require lubricant for this seal but you may use a gasket and sealing lubricant if desired.
