Serviced my Impulse 2.0 motor on a 2015 Focus Jarifra. Got a bearing kit from performancelinebearings.com. First class service. All bearings replaced. No evidence of water ingress so made sure to seal the motor case. Bearing replacement (x8 bearings and 3 seals) quite straightforward. My Impulse 2.0 motor had always had a problem whereby the motor would slip )felt like chain slipping)when stepping on the pedals with force so did the 'pawl spring' mod mentioned here. Made a new spring out of 1.0mm spring wire. Everything went back ok and have had two days of testing. So far so good.

Hi soundwave Peter at performancebearings gave me this info. (image below) Thanks for your contact and reply's to my question. I will post up how I get on with my attempts at Impulse 2.0 motor service / overhaul for info anyone else who might be struggling.

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.

Hi olepro I found your post 'Words about my Kalkhoff Integrale 8 LTD' really helpful and informative. I am experiencing the exact same problems as you describe and suspect the 'pawls'. I am confident of fixing this myself in a similar way you outlined. One question I hope you may be able to answer is after taking off the crank arms there is the Impulse chainring / spider on the crank axle. How does this come off? Does it simply pull off the splines? or is it a lockring? I attach a photo of my motor for reference. Thanks.

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. I have an ebike - Focus Jarifra - 2015 model. I am here to ask a question and help anyone else if I can. I will ask question in a relevant section. Thanks
