SPD stripped thread?

[Smiler1968]

Looks like I should take this as a lesson learnt and take more care next time. I might try pulling them apart just to see if I can but I think they are for the bin. Thanks for the advice.


I'm a trendy consumer. Just look at my iPad using hovercraft full of eels.

there are wee tangs on #4 but they are just for location, to stop the thing from turning separately from the pedal body.

Agreed.

Any vertical load on the cage is is borne by the sleeve, which if it is damaged or broken. will likely bear on the spindle and scuff/scrawp away like nobody's business.

cheers

Looking at the linked pdf again I think it's a bit of both and the load is spread over #2 & #4,and I agree it probably wouldn't help the sleeve to spindle contact from a scrawpage POV,however it's all academic really as the OP won't be able to strip the pedal down without damaging the cage and #4 Better to ride it to destuction and buy new at that point.

not really. The tangs are tiny and feeble. Without sleeve #2 supporting #4 the tangs will likely be mangled the first time the pedal is used.

Part #4 takes the place of a spacer sleeve in the cageless but otherwise similar PD-M515 model. The tangs break off the spacer if the pedal is assembled clumsily (ask me how I know.... ) .

I wonder if the cage can be protected from heat well enough with wet rags. A small blowtorch flame will concentrate the heat in the required area.

BTW I think you can buy the LH cage from SJS..... but not the RH cage.

cheers

OK,but trying to melt remainder of #2,even if the cage was able to be protected,would not #4 also be melted in the process?
Is #4 available as a spare?

[Brucey]

hence my suggestion that the remainder of the sleeve (the part that moves) is cut away. The #4 part will then slide towards the threaded end of the spindle which should be far enough out of the way whilst the pedal body is heated, provided wet rags/tissues are correctly employed.

BTW I cannot find the #4 part as an available spare.

The #6 cap unit will still be in place when the pedal body is heated, and again should be preserved if wet rags/tissues are correctly employed. This part is available as a spare though.

cheers

I can't see #4 or the cage surviving the heat treatment but if the OP doesn't plan on using the pedal as is then he's nothing to lose but personally as I up thread I'd ride the pedal until it fails YVMV

[Brucey]

well, put it this way, if the pedal body were made of steel, I'd happily weld onto it whilst protecting the plastic parts with various wet tissues/rags. Welding generates temperatures which are above 1500C. To get the pedal spindle out one end of the pedal body needs to get to about 150-200C, and if the plastic parts are ~50C or so cooler than that, they will be just fine. Not super-easy, but possible, I think.
