Impulse 2.0 Remove chainring / spider

[Ciano]

Hi.
I have a 2015 Focus Jarifra with an Impulse 2.0 motor. I have some problems with it slipping / making noises when under load. I understand these motors are problematic from the threads on this forum. Iam quite competent mechanically and would like to disassemble motor and have a look if there is anything obvious Ican fix.

I attach a photo of chainring / spider. Taking off the cranks reveals the chainring / spider. Does anyone know how this comes off? First thoughts were the silver notched ring on the BB shaft (28 notches and about 30mm diameter) is a lockring?

But then thought is this assembly just pressed on? Could not find any obvious tools that would fit if it were a lockring. So wondered if anyone knew before I start prying etc.

Thanks in advance.

Hi soundwave

Many thanks for that contact.
I emailed Peter and he got back to me with the info.
I think at the very least Iwill get the bearing kit from performancebearings
and if it seems too big a job i will request their full services.

Thanks again for your help.
