It had lost compression. Thus the reason for pulling the head off. Value was stuck. Got a new gasket set. Thanks for the information, I will keep it in mind next time I get an old mower.
I’m not stupid I know what I am seeing when it is disassembled. But frustrating when the diagrams don’t match with what is actually inside. I’ve had both mowers pulled apart and they both identical inside. Only oil sea on the intake valve stem.
868 is the part but it doesn’t really show it in any of the diagrams I’ve looked up. The part is there but doesn’t show where it actually goes. It might be an unserviceable part. I put it all together with the damaged seal. The little spring on the oil seal has gone off and it’s slightly...
It’s 9T502-2091B1
I have two identical mowers, looking up this one gave me the engine same as mine. It’s definitely the intake valve. It’s the oil seal between the two chambers ie valve stem and spring
It is the intake valve oil seal. I ve had the springs out. You can only access the seal from the end you put the valves in. Also you have a different model listed. I have attached a photo of the the motor diagram and In red you will see an arrow, that is where the intake valve oil seal is
I was doing a full service and decided to clean the valves and head of carbon build up. I have damaged the intake valve stem oil seal. I have sourced a new seal but don’t know how to get old one out of install new one. Any help appreciated!
