Title: Axle thread size
Post by: tbiceman on August 01, 2014, 12:51:33 AM

I have a rear mounted mp2. Going thru the forum I find various different answers on this topic. I would like it simple as I new to this. Are 3/8"×24tpi, 3/8"×26tpi, or some other size. Don't want to weaken the axlle by tooling it as this is on an e-trike used for carrying up to 200 kg. Any simple help would be appreciated**

Hi and(https://i.imgur.com/evDSMvT.png)to the forum.

There appear to be two thread sizes used on the Magic Pies and they are both metric, so you have a choice of either M14 x 1.5mm or M14 x 1.25mm.

All of my Magic Pies and Smart Pies have 1.5mm pitch threads on their axles but you will need to measure yours to find out whether it has a 1.25mm or 1.5mm pitch.

If you check out this post (http://goldenmotor.com/SMF/index.php?topic=5089.msg29511;topicseen#msg29511) it shows you how to measure the correct pitch of your thread.
