Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Bought : A not used M3W Bevel Box

Thanks Kevin and Roger - another improvement to save up for!

From what’s remember tried Garage 56 a few years ago also to develop a quiet BB but they didn’t succeed.
Does Billy Bellinger has more technical know-how as Garage 56 ?

He is a specialist in rebuilding gearboxes and rear axles.

Mine was and is always quiet from new

You are very fortunate!

The bevel boxes are like Russian roulette, the good ones and the bad ones.

Slim Pickens as Major Kong - Nuclear combat toe to toe with the Ruskies. Quote from ‘Dr Strangelove or: How I Learned to Stop Worrying and Love the Bomb.’

I think that if the price is close to a new bevelbox it is because he puts new gears inside.

85w140 or 140 oil lowers the sound compared to redline red.

I am totally new - This is actually my first contribution for my colleagues on TM - so when I misuse the forum please tell me.

Following my "want to buy" and "bought a bevelbox" thread I will write about it

Analysing the Bevel Box.

The plan is to get a thoroughly understanding of the noisy Bevel-box.
Many other owners have given me already a lot of very useful information.
The goal is to find ‘another (?)’ solution to get the Bevel-box better maintained and most of all more silent and maybe give that service to other owners in case they like it.
I do this together with my neighbour who is Landrover technician.
I am for sure not the first one who starts such a project, but upon till now I have not find real answers.
It will also take a long time before I have come to a real plan of approach.
In the mean time I will keep you informed through this thread.

I am besides a sailor by profession also and analyst and like to do research, especially when it concerns maths, physics, mechanics and electricity and electronica ( Ham operator ).
In fact when I could buy this beauty from Steve, my main reason to buy a M3W was that I bought something on which I could – have to - work and try to improve.

Because the first thing I want to know about the Bevel-Box is temperature, I decided to create an extra Dashboard, where I could control the Bevel-box temperature.
And because I have a lot of other possibilities with these fantastic and flexible Auber-instruments I used it also for Engine-oil pressure and other – for me - important things to know.


Chapter


Because the whole project started with an analysing project of the M3W Bevel-box, the first sensor I bought from Auber was the same temperature sensor which I used for the engine.
I have installed this one instead of the drain plug of the Bevel box.
On Amazon.fr I could buy a M16 to 1/8NPT bold which I used.
The inside diameter was just a little bit wider than the sensor.
To get more fluid flow I drilled the hole to 12 mm.

I made a relay behind the new Dash, so I can switch between the Engine temp and the Bevel-box temp.


The dashboard
Following you will find some documents which hopefully explain the other functions of the dashboard and how I made it this winter.
Because I could not download a MS Word file, I made from a pdf file four separate pdf pages which I converted to jpg files so I could give you – via TM-Images - a document to read.

Some extra’s
The dashboard has also a fitting for a “Tire Pressure System” and two switches/regulators for my motorbike heating vests and a USB outlet for the Programmable ECU which I bought from Bunny.

I hope you enjoy reading it.

and I even could get pictures in the post
