How to Repair Stripped Damaged bicycle crank arm pedal threads with a thread insert.
This is my take on this repair to a Shimano 600 LEFT crank arm.
As this is the left arm, the thread is reversed.. you need LEFT hand threaded tools and inserts.
i already had the Tap and the drill bit but these can be bought from eBay.
all I purchased was the thread inset for around £7 at the time of filming.
The insert has an internal thread of 9]16"x20tpi with outer thread of 5]8"x24tpi
drill out the old thread with a 14.5mm the tap left handed, clean and screw in the insert with lots of thread lock and let dry as per the manufacturers instructions on the bottle.
file the insert flush with the arm. jobs a good en
We hope you enjoy the video & Restoration.

Interesting 👌💯
Thank you. I thought the same that's why I made the video.
Do I need the insert thingy u put in the thing?
If your threads have gone , yes you would need the tools and insert to do this.
what about the size in the right side the drive side what is the size of helioils?
Hi thanks for watching. I only did the left side. Never looked into the right as the thread was still good.
what is tha size of bushing?
Thanks for watching. The answer to your question is in the video description.
Hello, use 5/8-24 tap？
Please read the video description it explains there.
5/8" x 24tpi bsc I used left hand thread. For the left arm
Hey I was riding my 2000 specialized Vegas TRX and went to pump hard and my crank just like stripped. Basically it spins without turning the chain ring. What do you think happened to it? Is it something I can fix and keep the crank arms? Want to keep bike as original as possible
Hi thanks for watching.. I'm not entirely sure on mtb bikes. First thing would be to remove the arm and see if the chain ring has broken from the arm and go from there.
Tap size for helicoil is 5/8-24 ？
Please read the video description it explains there.
@@whitewellybmxrestorations you stated the coil size only, wonder if the tap is same size?
@@fuluk169 5/8" x 24tpi bsc I used left hand thread. For the left arm
I can find “5/8-24 UNEF” in the market, wonder if its correct？Do u have pic of the tap？
@@fuluk169 I dont think it's the same . I will have a look
What is the size of the Thing you put inside the thread? And what is it called and what is the thing that you use to rethread the hole?
Hi thanks for watching. All the information is in the video description.
Could you make the music more distracting
I probably could yeah. Lol
