How to Easily open and repair your CYC Photon motor

[@MarkFries-o7n]

Very informative. You make things less scary to work on!

[@Crypt0rkid]

You inspire me to show how to service my particle accelerator!

[@hindesite]

I think you previously loosened that ring, there is a metal incompatibility problem that causes the ring to gall and freeze in place. CYC recommend assembly with a copper based anti freeze grease. Still sucks for us early customers though.

[@JohnnyNerdOut]

I know what you’re talking about. Getting that proper tool is night and day though. That with some leverage should take care of you unless you have some corrosion issues.

[@hindesite]

Any suggestions for a heat removable sealant for reassembly?

[@ChrisBFerguson]

Great video.

[@Dupie69]

Mr. Nerdout, my child has a jetson dirt bike. It has power and you can hear the motor trying to run but bike won’t move. Also, it won’t roll backwards. I’m assuming a gear or bearing broke in the rear wheel?

[@JohnnyNerdOut]

Ya, check the planetary gear

[@Dupie69]

@@JohnnyNerdOut will do! Thank ya sir. I’ll keep ya updated.

Have you been inside a Stealth Gen 3 yet?

[@JohnnyNerdOut]

Only a little

[@richardclarke6037]

Hi Jonny ate you familiar with the major or most common issues with the bafang m620 motors

[@JohnnyNerdOut]

Not really. I haven’t worked with those motors in a few years. Mainly it’s the bbshd and bbs02 kits I work with now.

[@markbyerley6967]

My photon was returned from repair with the retaining cap on and the chain ring off. The retaining ring just spins the motor because nothing to hold. Appears to be seized or over tightened. Ideas on how to remove ?

[@markweatherall7437]

Hey bro, your video popped up on my utube feed because I follow you and watched several of your videos over the years. Have you done a video on how to service/degrease etc the Bafang BBS02b or the BBSHD and if you have could you please add the link? Thanks.

[@JohnnyNerdOut]

I haven’t done a video on that yet. But there are tons out there already

[@markweatherall7437]

@JohnnyNerdOut Ok thanks, my BBS02b has done 7000 miles casual pedal assist use in 3 years and hasnt missed a beat but I've thought about opening it up to put some fresh grease on it and change the nylon gear etc but I still hold the belief in my head of my father's engineering skills saying - (if it ain't broke don't try to fix it). Suppose prevention is better than cure similarities to changing your engine oil in your car but that's a combustion/gas engine and not electric.

[@ungwamabibi1861]

I have heard the photon's have overheating issues than can damage the electronics. Is this a concern? I am considering one for my next build as I want torque sensing.

[@JohnnyNerdOut]

Maybe a couple of years ago but not so much anymore

[@hindesite]

No, the motor is automatically throttled and protected when it reaches a threshold temperature. IIRC about 80 degrees.

[@MHH3180]

Send me an invoice, including shipping, for thst tool...Mark from Ruby's

[@JohnnyNerdOut]

I’ll be back in the shop on Monday. I’ll try to remember. If I don’t just shoot me an email 👍

[@TK-OK]

Nylon gear like Bafang ?
