Fitting New Reluctors
How to fit reluctor ABS rings both ways
On most occasions you just can't repair the reluctors so you need to buy new ones.
Smart don't sell the rings on their own but smartmods.co.uk does.
We like to test ours against our "competitors" (said in a sarcastic voice simply because all the other
reluctor rings we have obtained for testing have been terrible, poor corrosion resistance, strange
sizes or wildly out of tolerance). Smartmods don't cut corners because they aren't profit driven.
Using an 18mm ring spanner and E18 socket, remove the bottom x-frame bar bolts.
Put the drive shaft bolt back in about 4 turns and pound with a rubber mallet.
It shouldn't take to much but eventually the shaft will move most of the way out.
Remove the drive shaft bolt once again.
You can now push the hub away to release the end of the drive shaft.
Lift it up out of the bearing housing.
Lever the other end out of the gearbox.
And you now have the driveshaft out. Repeat on the other side.
Here you can see the fault, the ABS reluctor ring is split.
Take it off and thoroughly clean up underneath until you get down to the metal.
Fitting Option 1 - Sweating
Silly name but that's what the process is called. Heat the ring up until it glows red all the
way around and lower it into place. The heat expands the metal enough for it slide on. Be
warned though, you need an excellent gas gun to be able to get enough heat into the ring.
MAPP Gas torches seem to just about do it.
Fitting Option 2 - Drifting
This method requires you to slide the new ring into place using a big-assed hammer.
Place the new ring on with the old ring over the top. The old ring is sacrificial and takes
all the damage as you can see. Hit evenly all the way around until the ring is in place.
With the ring correctly fitted, give it a spray of exterior grade paint. It's an extra lever of protection
but mainly it creates a seal between the shaft and the ring to stop rust getting underneath.
Refit the shafts <beavis>shaft ha haha hah</beavis>.
