Default Sensing the speed....

My objective at the moment is to get everything around the gearbox finished so that I can refit the gearbox tunnel before installing the engine loom.

So I have turned my attention to fitting the speedo sensor. I decided to use the lobes on the gearbox out flange that has been successfully used on other (Marlin) builds.

I had to make a bracket to hold the speedo sensor that is rigid to hold the sensor 2mm from the gearbox flange lobes.I started with these two pieces of steel strip that I then welded together.

After much fettling and trialing it looks like his. The cable from the sensor is very thin and fragile so to I sheathed it in PVC sleeving and covered the end in a few layers of heatshrink.

The speedo sensor bracket is fixed to one of the gearbox mounting points. It is supplied with spring washers but I also used a dab of threadlock to hopefully stop it loosening by vibration.

I've painted the gear selector support brackets that I made about 2 years ago and have nearly finished fitting them.

I've also finally fitted the clutch reservoir after painting the mounting bracket. The output ferrule was too large for the hose and there wasn't space for a reducer so I had to the reduce the diameter of the ferrule with a hand file. Very tedious.

I started to bleed the clutch hydraulics but I found a leak in one of the pipe joints so I had to stop, drain the reservoir and repair the joint. Bit of a 'bleeding mess' so that will have to wait for another day.

So a few small, but very time consuming, jobs completed..........
