Hey, the bore in the casting for the quill was oversized. Have a look at part 2 for a relatively easy fix.

Thanks Cheryl!

Thanks Jack!

Wow, that's ace. The Rohloff Speedhub is not only the antithesis of our modern throw away culture, it also stands against the bicycle industry's ever changing modern hub specs - many of which will probably become obsolete in a few years. The world could learn a lot from Bernard Rohloff's design ethos. If you carry out regular oil changes I'm sure your hub will last many years longer. Have you had any issues with the nylon drive pins shearing on your ebike? As it happens, I'm planning to build an ebike with a Rohloff and a bafang 1kW mid drive motor in the next few months.

I have hub #11 since I bought it second hand in 2012. Send it in for an official service and has been running solid ever since. So your not lucky, they are just great pieces of kit !!!

It's ace to hear your early hub is still running. I wonder if they replaced the internals when you sent it in for it's official service.

@@dirtbagd89 I actually have no idea. Didn't open it up after the service. Just did the anual oil changes myself. I assume they kept the internals but changed bearings and seals (at least given the cost of the service). Cant remember the exact pricing but assume it would have been way more expensive otherwise.

Hey, the gear set up for auto feeding is shown on the table on the belt cover. The table gives you the gear set up for feed rates of 0.1 and 0.2mm per spindle revolution. Have a look at the photo at 18:05. in the video.

Yes you could manufacture bolts with this machine. If you were using round stock you'd need a filing rest and a way of indexing the chuck to form the hex. Of course this wouldn't be needed if you used the correct size hex stock.

@@dirtbagd89 was thinking of making some titanium bolts for my motorbike die to old ones rusting

Thanks!

Thanks for the tip.

Thanks Robert. Did you use it to change your belt?

@@dirtbagd89 not yet but I have downloaded the step by step guide 👍

@@yt240robert Oh nice one. Let me know how it goes.

Hi, sorry I'm not sure what the problem is with your hub. My understanding is that gear 6 and 13 are essentially the same gear but gear 6 uses the third planetary gear set to get the extra reduction. It sounds like there might be a problem with the pawls which engage gears 6 and 13.

Hi, I paid £400 for the hub and spent about £150 repairing it. Sending it off for repair may have made more sense. However, I learnt a lot and now I have the tools needed to replace the bearings and seals in other hubs.

@@dirtbagd89 wow! £400? You got a great deal! I was trying to fix it on my own last time coz the seals are worn out and the oil was leaking. It’s good i found a reputable certified Rohloff mechanic near our place.

Good luck with it!

Thanks Ian! I'm almost finished the drill now. I just need to machine the pulleys. Good luck with your projects

Hi Bob, thanks for your comment. I'd glad you found the video useful. All the best with your project.

Cheers. Glad you found it useful.

Oh no. Sorry to hear you're having problems with your hub. I'm sure one of the Rohloff service centres could sort it for you.

No worries, Mark. I'm glad you found it useful. Yea thankfully you don't need to remove the carrier for the rear brakes. It's a different story with the front brakes though.

Thanks for your comment! I'm pleased that the video has been promoted by YT enough to reach some fellow bike nerds and Rohloff enthusiasts.

Hi Andreas and welcome aboard! Thanks for the great feedback.

Thanks Daniel, glad you enjoyed it.

Thanks Ollie!

Thanks! haha, I'm glad you approve of the Carhartt gear!

Hey. Unfortunately you would have to swap out the internals of the hub to change from CC to TS.

Hi Ade, thanks for this comment. I have watched many of your videos and have found them very helpful and informative. Thank you for making the effort to film and edit them! I quite like the old school belt drive speed change because it's simple and there isn't much to go wrong. Speed changes may become a little tedious though you're right. All the best.

Thanks! Yea, I looked at the 180 but wanted something slightly bigger and without electronic speed control. I got fed up with my mini lathes electronic speed control breaking. Hopefully the 240B will treat me well.

It would be pretty difficult. Your best bet would be to remove the hub assembly from the car. Then you might be able to punch the old bearing out in a press or with a big hammer. Getting the new bearing in without damaging the ball races would be almost impossible though. You'd have to make a collar that goes behind the flange and sits on the outer ball race. Good luck!

Just bought mine from eBay about £50

thanks for that! @@dirtbagd89

actually, what axle stands do you have?

I've got the 3 tonne halfords ones. I just remembered that I had to ask the ebay guy specifically for the 3 tonne compatible pads because the standard pads are for the 2 tonne axle stands. He can machine the pads to suit the 3 tonne axle stands so it's no problem, just send him a message.

Great stuff thanks for that.

good. job

Thanks!

I have tried to follow Dan Burkhart's video on the Speedhub a number of times and I understand the basic principles. However, the way the shifting mechanism works inside the hub is a little beyond me. I think it's amazing how someone could imagine, design and build such an intricate mechanism. RIP Bernard Rohloff and thank you for your wonderful creation!

@dirtbagd89 I was sad to hear about Bernard as well. Seems he left way too soon, but that's between him and his/our "Designer." I know he's in an amazing place now that transcends the mere physical realm. Hope his family are finding comfort with their loss. Thanks for sharing these videos. They'll find the ones that need them.

Thank you! I broke the centrifugal switch by accident and I couldn't find a replacement for the imperial shaft diameter. Using a timer rely seemed like a good alternative and I thought it would be an interesting project.

@dirtbagd89 Makes sense. Sometimes replacement parts are no longer available, and we can only improvise. Great idea, and very professional!

Given the harsh envirnoment it operated in it was quite an achievement to get the car beyond 200k miles. A reliable workhorse but just couldn't resist the ravages of Scottish Highlands road salt.

haha, yea it's a filthy job!

Glad you found it useful!

The external gear mech is aligned by ensuring the two pins on the shifter go into the two holes on the gearbox where the pawl springs are located. You also set the gearbox to 14th gear before installing the pinion gear.

@@dirtbagd89 This is on an E-14 Hub. I think the dealer replaced the internal gears under warranty. The shifter was in 9th gear when the wheel was sent to the dealer. Bosch Kiox Controller allows you to choose a start gear whenever you stop and start. That's why I know the shifter was in 9th gear when I sent the wheel to the dealer. They sent the hub back and my Kiox says 9th and will only shift to 14th and will not go below 9th gear. You wrote: “Set the gearbox to 14th gear before installing the pinion gear. I think the new gearbox was in first gear, and he reinstalled the shifter that was in 9th. Gear position. what do you think.

​@@briananderson6142 From what you're saying it sounds like you need to remove the electronic shifting mechanism and manually turn the 8mm hex on the external gear mech to get the hub into 9th gear so that it matches what gear the electronic shifter starts in. I'd recommend turning the hex on the external gear mech anti clockwise to its furthest extent so that you know it's in 14th gear. Once you've done this turn it 5 clicks clockwise to put it in 9th gear. Then you can reattach the electronic shifting mechanism.

@@dirtbagd89 I am going to try this and tell you the results. Thanks

@@dirtbagd89 Good advice, problem solved, and all gears work fine. The electronic shifter needs to be shifted to the 14th gear or first before being sent away for service work to ensure this doesn't happen, mine was sent away in the ninth gear. Thanks

Hey Peter. Both contactors are rated to 18 amps and have a 230v coil. You can get them relatively cheaply here: www.ebay.co.uk/itm/332619693844?hash=item4d71adbf14:g:s44AAOSwq1JZHY4p. To be honest your cheapest option is probably to find a another second hand motor that will work. You're looking at £100 for the parts alone to make the starter unit with integrated timer relay. If you send me your email I can send you a list of all the parts I used. If you aren't happy building the unit yourself we might be able to sort something out.

50Nm then another 45 degrees.

What size is the Axel nut?​@@dirtbagd89
