Tightening locknuts on Deore DX pedals - drat and nuts?!

[Tootyred]

Cynical......me! No.

I'm all set to get the pedals back from the LBS this week if I can get away from work early. I'll then measure the nuts and get back down the hardware emporium to see what they've got. Have angle grinder, sure can I get something to work somehow!
Was thinking/ hoping one of those screwdriver-handled sockets will pass down the middle of the larger tool. I think a box spanner thinned-down will sneak inside the pedal body. I had a 'try' of a box spanner in the emporium before handing over to the LBS - it nearly fit, so think it should work. I gave the pedals to the LBS as I had hoped they had the proper tool or knack - they had neither in the end.
I'll post pics on here if I can get some success. Then I'll make loads of tools and put them on ebay and become a miwionnaire!

The Shimano Tool TL-PD63 is designed to adjust two different pedal sizes

The tubular sockets measure outer 11mm / inner 8mm or outer 10mm / inner 7mm

All sizes nominal and measured A/F ( across flats )

Thanks for the info. I didn't realise that TL-PD63 is a double ended Shimano tool.

And unfortunately I don't think the box wrench idea will work. I remembered that I had bought a set of box wrenches years ago. They are all double ended, and I had previously cut the 20mm - 22mm wrench in half for a front suspension strut job on my car.

This is the set I have:

8pcTubular & Metric Box Spanner Wrench Spark Bar Set Plug Sockets 6 - 22mm | eBay

Double ended spanner so one spanner has 2 different sizes. Tubular box spanner set. Zinc coated for rust and corrosion resistance. Complete with tommy bar that is 170mm long so long enough for when extra torque is required but not to long that it gets in the way or restricts access.

The box wrenches are forged in such a way that the socket area is significantly wider than the main body of the wrench. This means that a 6mm - 7mm box wrench will not fit inside a 10mm - 11mm box wrench.

My original idea of using thread lock might work if a socket or box wrench can be modified to fit the cone nut.

Progress time. 11mm box spanner (well, a 10 and 11mm box spanner, chopped in half) obtained and thinned in the walls so that it fits inside the end of the pedal body. Piece of pi$$ with an angle grinder. Same done to an 8mm socket - now passes down within/ inside the box spanner. Socket extension bar bought so that I can operate the 8mm socket with a torque wrench (a nice low Nm-rated one for light duty).

Question is what torque to tighten the outer locknut? There's probably a standard for the thread of the pedal spindle but this update is as much as anything an update to say that it was pretty easy to knock-up a tool to do the same job as the £60 Shimano jobbie! It probably cost £6.

Well done on making your diy 'Shimano' tool !
There is not a great deal of load on the m5 locknut as it merely serves to stop the outer cone
from rotating out of adjustment . Its all made from high tensile steel and a torque of
about 7nM should be more than adequate , though I prefer to rely on 'feel' for that type of thing

 

[TreaderSteve]

Cheers! Agree, a little research suggests 5-7nM. The problem I encountered y'day when trying to use it is that the bar that passes through the 2 holes in the box spanner obvs doesn't pass through now due to there being a socket and extension inside. I had hoped just using one hole in the box spanner would give enough purchase but alas no. A trip to my brother's is needed to weld the bar onto the box spanner to make a wee little handle. Then I'm all set!

I’ve got this tool. Doesn’t fit inside dx pedals

Ha! Not a chance in hell I would have spent £60 on the tool anyway - for me to have then been disappointed! Great info though!
