nexus inter-4 hub gear wheel removal?

I have a new Mezzo I4. In the service manual they refer to Shimano tech. service doc. SI-6E60A for the correct procedure for disconnecting the shifting cable in order to remove the rear wheel. Trouble is I cannot find SI-6E60A anywhere.
So, I am hoping someone here can help me, either with instructions or a link to Shimano tech doc SI-6E60A.
In case of puncture, I would like to know how to remove the wheel.

One other question: Will 16 x 1.5 tubes into my 16 x 1 3/8 tires?

Many thanks, Bangkok. For some reason, when I googled I came up blank.

You can make them work. The risk of pinching the tube is somewhat elevated. Be careful and patient, and you should be okay.

The listed document is actually how to disconnect the cable so you can remove the shifter, perhaps not too useful in the event of a puncture.

For disconnecting the cable and removing the wheel, see SI-4R35A from the Shimano Tech Docs page.

1.5 inch in a 1 3/8n should be ok. Check if 1 3/8 were included on the suitable applications marked on the tube box is if you still have it. 1.5 in a 1 1/8 tyre will not be in my experience.

Why did you buy the D4 over the D9?

Isn't a 16 x 1.5 a 305mm, while 16 x 1 3/8 is a 349mm?

no, this refers to the wheel rim diameter,not the width of the tyre

I tested the D9 and didn't like the way it shifted. The D4 shifted smooth and felt good. However, after 50 miles I find the bike very noisy. It clinks and clanks along (drives me nuts)!

Exactly, so wouldn't you have to stretch a tube meant for a 305mm rim to fit it on a 349mm rim? Or if the other way around, wouldn't the fit be too loose.

Points to check for noise;
1/rear hinge for excessive slack ,they are adjustable.
2/allen key bolts that tighten up the stem hinge,however if you over tighten these it would move.
3/play in headset
4/you are tightening the front QR aren't you? Dangerous if not.
5/seatpost clamp tight enought ,newer versions 2005+ are solid anyway.
6/check chain clearence on the folding guild near the front gog.
7/check rear rack tightness

Else get spokes checked for tension.

I have 2 Mezzos', no noise on mine other than the seatpost clamp on the older version,which I can always change to the newer version.

inner tubes usually come in a number of suitable applications. ie an 18" will fit a 16" bike,one needs to check the specs.

OK, I returned the 1 1/2 inch tubes to my local bike shop, and I am taking the bike back to Bfold today to investigate the noise. In truth I would like to return the bike and exchange for another, but I don't think that is possible with Bfold. I will follow up later.

DO you mean to swop for another model? IF so
What is it you do not like about the bike?

Unless there is types out there I have not seen remowing rear wheel and shifter cabel on a nexus is the same for 7 speed and four speed. I find t easy (once you understand the system) and this is the main reason I really like the Nexus hubs. Also the fackt that there is no clickboks sticking out is great.

You can use a Sram IHG without the click box if you prefer. Just use a toggle chain as old sytle Sternley Archer used.

Really? Pix or link?

I just started realising that the Sram is a good hub, good range and need less maintenance than Nexus. Stilllike the "no nonsens, nothing sticking out" setuo of the Nexus.

follow up

i was skeptical, to say the least, that my problems with the Mezzo I 4 would be solved, but, David at bfold
definitely knows his stuff. Tightening the bb bearings solved one problem, and a little grease on the seat tube clamp shim, voila, problems solved. Now I am very happy with the bike. I enjoyed a great ride around the city today. The four speed hub, I feel, is great for NYC riding, and fills the bill also for riding in the Berkshire hills of western Massachusetts where I have my home. It is heavy to lift and carry, however, so be advised if you are considering the four speed hub.

Thanks, I will try this on my older version. I might just get the newer seat post clamp, as it is much better clamp.I will see how much it is.

Yes I agree with your comments about the bike in a city, but i have upgraded the gearing and added bullhorns. I find this makes it much faster, it then becomes more of a tourer or a fast city bike. See my upgrading a mezzo thread for details"

He removed the clamp and greased the lower portion that goes over the frame. No grease where the seat tube touches the clamp shim.
