    Bosch Cx motor noise

    Thank you electrifly. Technically, on a new motor you should have a nice new greased seal. It maybe worth checking as I have seen several with no silicone grease behind the seal. I do add some to the right-hand crank bearing too, but I will have to wait till after winter to find out if it's...

    Bosch Cx motor noise

    £1 less than me! And I'm sure if you ask Bike.discount what that funny noise coming from your motor could be? They will be more than happy to spend hours emailing back and forth until you got to the bottom of it :rolleyes:. Yeah right! Guess what, it's only €10.95 from TiendaMTB! Sad really, I...

    Or you could buy it from https://www.performancelinebearings.com Yes, it is a bit more expensive than Ebay, but it goes to help pay for my overheads and the time I spend on 'how to' videos, emails, research forums helping people with motor problems, etc. etc. Sadly, this business is not making a...

    Bosch Cx motor noise

    This is madness! How can there be so much difference between dealers? How can they go directly against your consumer rights? As for Rustbucket, If it's just a main motor bearing on your bike? I can usually change one without leaving any witness marks ;)

    Would be interesting to try something like these? I have actually found some but after postage to the UK, too pricey! https://www.ebay.co.uk/itm/OMNI-Racer-Worlds-Lightest-TiN-Titanium-Ceramic-Bearing-6902-61902-15x28x7mm-/372178291201

    I tried to get an LLU bearing for the SES sprocket today and no luck! I am now determined to find one!

    Bosch main bearing

    The LLU bearings are easy to find if you want a MAX but as we know that won't work! I am going to see a bearing supplier tomorrow morning. I will pick some up if they have stock. If you send me your details, I'll send you one to try. It's worth it for that sprocket link you posted, I got to get...

    Bosch main bearing

    Nice bike and setup The side load shouldn’t be a massive issue for the bearing. I guess it wears the sprocket a little quicker? Have you tried a bearing with LLU seals and definitely smear the silicone on the outside from time to time. I was doing a bearing every 200 miles and now I’m getting 8...

    Have you read the thing I did on SES bearings? If anyone buys an SES bearing from me, I pre-pack the bearing with marine grade waterproof grease.

    Just to clarify for anyone reading this. A "MAX" bearing is a bearing with no cage to hold the balls and therefore can carry more of them. It has about 40% more strength than a cage bearing but is designed solely as a high load pivot bearing. It is not designed to go round and round. If this...

    Personally, I wouldn't bother on the Yamaha because the bearings are exposed unlike the Bosch motor where the bearings on the crank side are recessed. Water lies in this recess after washing or transporting and you can pack the grease. One of the things I do before assembling any motor, is put...

    If they are talking about the motor bearings then ask them for the bearings! And when they can't supply them they will have to change their tune!

    Just to prove most current motors are the same, these pictures are of an Impulse 2.0 motor sent in for repair last week.
