Modifications - Indicators

I've decided to fit Amelia with indicators, in deference to modern traffic conditions. They are typical Lucas look-alikes, and don't look too out of place.

Front indicators retain the headlights



These little tabs are cut from 3 mm thick sheet. They have 3/8" UNF nuts welded to them to suit the indicator stalks:



They weld to the rear mudguard stays:



For wiring up, I am using these 'Japanese Bullets' - small crimp on connectors, fully weather proof.



1.0 mm2 three core is useful for indicators. I like to make an entirely separate loom for the indicators, so that they can be removed easily if another owner wishes to do that:


Put a dedicated earth wire into the shell and attach it to the bulb holder with a ring terminal. By design, the earth path on these repro indicators goes through the plating... Nasty...

So, what you can do is bring an earth wire down the indicator stem to a dedicated earth wire. The earth wire can connect to one of the bulb holder mounting screws. Normally I don't use these modern terminals, but no-one will ever see this:


The handlebar switch is available as a generic indicator switch from many Brit bike outlets. It has three wires: a common yellow wire from the flasher unit, and red and green wires for right & left:



All the wires come into the headlamp where the red & green wires are terminated with a Y connector: one path to the front indicator, the other into the loom heading to the rear. The yellow wire connects to the flasher, which sits in the headlamp shell, protected by a rubber sleeve - MZ style!



The flasher is supplied from a dedicated fuse

Oil Filter

These are a few shots for the record of how the oil filter ended up after moving the pipe around and bending up the copper return pipe:
 
Filter mounted as high as possible, angled so the element can be easily removed

From underneath. You can see how the element comes out easily

The hoses curve around the gearbox. You can see the special copper return pipe with a 150 degree bend

Oil Filter

Here chaps & chapesses is a small deviation to our Square Four restoration - an oil filter. This is an aftermarket filter housing intended for a Commando - it uses a standard spin-on filter cartridge.

I'm mounting it under the gearbox, between the frame tubes on a steel sheet metal barcket, mounted on the engine/gearbox tie studs.

It mounts with two 5/16" UNF screws, which I have purchased in stainless.

Right now, it's too high. I want it high, since we have a lot of sleeping policemen (speed bumps) around here, and twatting the oil filter on a bump doesn't sound like a particularly good way of improving engine life. However, having it this high means I can't undo the filter cartridge!

So, I plan to modify the bracket to drop the whole assembly about 1 1/2", such that I have clearance to get the cartridge off but it is also pretty high.

But, all that is going to have to wait for a bit, because I have no oil pipe. and since I have no oil pipe, I cannot decide how to route the pipe and I cannot decide on the final location for the filter.

Another job on hold.









The cartridge I used here was the the EMGO 10-26910 for the Commando (about 55 mm tall); you can use the Champion COF103101S (used on Citroen cars), which is taller (about 77 mm tall).
