Faulty Flex plate

Greetings. Im learning about my perkins 4-108. It has that clik clak clok sound that that happens when the flex plate is faulty. Can anybody explain what is the correct way to change a flex plate. This is a beneteau first 38. I have acces to the motor from the top and through the sides. Thanks in advance.

Re: Faulty Flex plate

You will need to remove the transmission from the flywheel housing. Then you will see the flex plate bolted to the flywheel, and it can be removed by removing the five fasteners holding it to the flywheel.

Of course this simple sounding procedure might entail sliding the engine forward to remove the transmission, or pushing the prop shaft back far enough for the transmission input shaft to clear the flywheel housing.....

Of course, if the "clack, clack" noise is just in gear at idle, you might just decide to avoid running the engine at that RPM in gear.

Re: Faulty Flex plate

Transmission removal is required, to replace the Drive plate.
Depending on the access, you may be able to use a lifting ring above the trans to attach a come along or chain winch to raise the unit and push it back.
Then you may be able to access the drive plate.
