Very helpful.....our bolts were actually just standard Phillips screws....everyone I have seen working on them it's the T20. We went out and bought the secure driver and didn't even need it lol.

[@jefferygreenlee771]

Great video… I was very apprehensive about opening the motor up but you made it understandable and relatable…. Thanks

[@gofasters1]

Excellent video I did exactly what you said and it went great. Do I have to clean out any grease in there before putting in the mobile 28? I have 1700 miles on mine and it started making a grinding noise when I throttled from a dead stop. After opening it up there's not much grease left in there.

[@jasonjenkins4213]

Yea smart idea notching the gear. And that is real good information too. Thanks alot. Now when my motor gets loud I know what to do.

[@stanpurves9677]

It looks like the gear Gloster after 3,000 miles could be changed. Some of the teeth on the gears have seen better days and I wonder about chain stretching? All things to consider when doing this kind of maintenance.

[@isaacserna7593]

Curious, after that noise was the hub spinning or not spinning?

[@fraserthomson5766]

4:09 the very best grease to use is Molykote PG-75 which is hard to find in small pots (UK shop does 30ml pots that is enough for 2-3 services). This is because some grease is petroleum based and softens the nylon gears causing them to fail early.

[@robertt6020]

Excellent How-To, Stan! Thank you!

[@josephpowell3949]

I use Lucas Red N Tacky grease because it is a lithium base grease, so it is safe for nylon gears. Far better than the white stuff. I THINK IT IS THE BEST BECAUSE IT IS MEANT NOT TO SLING OFF!

[@paulhench7762]

In Spain we use olive oil for everything!

[@woodsculptor675]

I love olive oil on my pizza.

[@dennisyoung4631]

But Olive Oil - while digestible for eating - is a poor lube for these gears.

[@jetmelt]

Great tips Stan!

[@colincampbell4261]

Freewheel removal tool is easy to use.

[@northyland1157]

My e-bike motor had Philips screws not security torx. I use an "impact driver" to break them free. I was also getting strange noise from motor only sometimes when giving the motor power. I didn't see a clear issue when i took motor apart, but found some thick dark grease, which I cleaned out and replaced with mobil 28. I also replaced the one way clutch and nylon gears with a whole new gear set. I'm now just waiting on a new tire to arrive because the old one was bald after 2000 miles and I hope everything will be like new.

[@billrimmer5596]

As soon as Stan drops a vid, I drop everything. Great job. It looks like the motor is the small one. I wish I had your low gear. Mine gives me plenty of clearance to take the screws out. Larger motors and bigger controllers use more juice. More speed equals less distance. But I would like the bigger motor for mine. Just because u have it doesn’t mean u have to use it. I am sure not many people accumulate the miles u do. U r a true “rat” in the best of ways!! Super channel!!!! Thank u Stan!!

[@stanthereservoirrat5934]

Thanks for the nice comment! Keeps me going!

[@billrimmer5596]

@@stanthereservoirrat5934 U r the one that keeps us going!! I have used a number of your suggestions. The one about the little electric pump was real good. I let the tires down to 9 or so in the rough stuff. As soon as I get back to the road I go up to 16. Handles way better. You’re info on the switches and batteries was also great!

[@user-DL8000]

Stan, you ever have to reglue magnets inside motor, I've seen j b weld used. Thank you. Great idea on the grinding of first gear. I will definitely use that...👍

[@hajdasz6304]

the white grease that was in the motor before was not lithium grease, it was most likely a syntetic teflon grease

[@catspaw3815]

good idea to notch the gear...thanks Stan

[@chanitoromeo]

good idea,gracias

[@pauly51]

3:57 I’m going with Mobil 28. I’ve also heard of molykote 44 being used plus Pg 75

[@dennisyoung4631]

Mobil-28 works good in these *and* in BBS-HD mid-drive motors. I’ve put it in both kinds.

[@ridingradsslingingstrats2846]

Thanks bud I'll give that a try ! I wanted to switch out my motor as I upgraded my battery to 52v 20 ah , triangle battery . I have everything here and now it's time for the swap . I'm also thinking of running both batteries . And mounting my stock battery on the back rack , My triangle battery in the frame if , I can get it to fit ? And you have the extended cable and the upgraded controller and LCD I got everything from Bolton .

[@JCisJD]

Thanks stan. Helpful

[@cal4625]

I'm curious how much opening the motor case effects it's IP water resistance rating?

[@TheLiddokun]

Definitely a shengyi motor. You didn't clean out the old grease before applying the 28? How much power you pushing from the motor?

[@E-BikingAdventures]

It's a Rad, so it's 500 Watt nominal 750 Watt peak even though Rad markets it as a 750 Watt motor. You can see in the video that it's smaller than a Bafang 750 watt motor.

[@pedrobaez8696]

Nice work Stan nice little tip i like doing things like this being a former motorcycle rider i move to E Bikes to help me fill my void.???

[@user-ci5jb7cx4j]

Thank alot mine is making noise going to use the mobile 28 ray from cleve ohio have good day

[@user-tq3jp5np7i]

I used red lithium grease works well

[@sudhakaran3067]

Planatary. Gears. Where. Is. Avail. Sir

[@justinbeynon7980]

what about lubing the wheel bearing?

[@SMG-lz1zq]

Hi Stan, Can you please do a video on adjusting the Radrover brakes so they don't squeal? Mine are driving me crazy. I can't seem to get them all the way quiet. Thanks, Steve G.

[@markburton5292]

breaks squealing are usually due to contamination, you can try using break clean on them if that does not work change out the pads

[@kurtismckemmie4850]

Rubbing alcohol also works.

[@pauly51]

Resin pads help

[@klimadjan9681]

dam mc guyver ur bike still work ?

[@kristjanrobert9220]

thank s

[@ericanderson8556]

What about adding more speeds? Like a double gear in the front. I need lower I’m the woods.

[@E-BikingAdventures]

Good idea for those who have a 34 tooth 1st gear. I never use mine either.

[@MrWolfheart111]

Hi there, What is that white plastic thing sticking up from inside the motor? Timestamp: kzbin.info/www/bejne/ipSolIJneqiBjZI with that black stripe around it. It would really help me if I could identify it. Thanks. :)

[@a.i.privilege1233]

"security bit" means anti consumer bit.

[@audacityhour3104]

Looks like the areas needs to be cleaned first .. that’s a lot going on in there

[@NewbFixer]

nylon gears = silicone grease

[@alicvel]

Can i use SLIPKOTE??

[@stanthereservoirrat5934]

Not sure what that is?

[@alicvel]

@@stanthereservoirrat5934 And what do you think of SUPER LUB?

[@KaneLono]

Your mom said KY works well.

[@gliderarts3573]

Whirring

[@okanaganrider4332]

The white gears look plastic or nylon. Have to be careful choosing grease.

[@adrpals2324]

You are correct. Do not use any lithium grease on plastic gears. Need to use a silicon type of grease.

[@electchick_]

Hi Stan, thanks for this video, it gives me hope that maybe mine just need a bit of grease. I would like to know what it sounded like beforehand as I want to compare the sound coming from my motor, do you have instagram or anything that I could possibly message you on? Thanks dude

[@stanthereservoirrat5934]

No I don't have a before sound. It made a whirring noise.

[@isaacserna7593]

Was the hub spinning after you pull the throttle after the noise or it did not spin
