Pfff, like you'll hear that over the noise of the engine :lol: It's probably been making that racket for years!

I've had those style of switches apart.
Some cherry pickers use them as a function selection switch, and once the original grease starts to dry out, they get a bit hard to turn, which is usually then a prompt for either the operator (or more commonly one of the idiots I work beside :bang:) to flood them with WD40/release oil/dewatering spray to try 'freeing it off', which then washes out all remaining grease, and they become impossible to turn, as the plastics used just bind against each.

Once you know how they work, you can normally work in some fresh silicon grease using a small screwdriver, provided you can get it to turn. Failing that, you have to strip it down to get grease between the sticking surfaces.

MC that switch is now history as it's in my dustbin - I already wasted too much time on it yesterday :clap:

However Parcelforce delivered the new switches from RSComponents and also a full set of documentation that I won for the Dorman 6LE engine - always best to grab these things as they flit past as opportunities are rare - these were on eBay (naturally).

So I started putting things back together to clear a bit of space in the tractor shed. The main air intake filter housings, starter motor, main alternator end dome and ventilation screen, and the lid to the main alternator connections all went on easily.

awemawson:
BUT - when it came to mounting the fuel solenoid plate and solenoid it was a different matter. The axis of the solenoid was a good inch out of line with the axis of the ball joint on the diesel injector pump.

Then I remembered - prior to painting I'd flattened out what appeared to be a random bend in the plate that certainly didn't look as though it was supposed to be there. I suspect that the solenoid has been replaced at some time and this one sits with it's axis higher than the original. I thought just bending the plate and letting the actuator work at an odd angle wasn't very good, so I cut the plate and inserted a 1" joggle piece to get the heights nearer kilter.

A quick coat of primer and matt black, and while it was drying I sat down and drew up the new meter panel in Autocad. Dropped it as a DXF into SheetCAM, ported it to the CNC plasma table and cut it out in 2 mm steel plate. The original was 1.2 mm but very flimsy as the square meter apertures are nearly as wide as the panel itself.

I left the mounting holes off as I wanted to replace the (previous) self tapping screws with Rivinuts and they had obviously been set out by eye rather than from a drawing so to match the cabinet I had to use the original panel as a drilling jig. Drilled 3.1 mm, opened up to 5.5 mm for a bit of clearance on M4 screws, and fitted Rivinuts in the cabinet face.

A quick grit blast and a coat of silver hammer finish paint left over from the Versatool Cabinet refurbish, and while the paint was drying I returned to the fuel solenoid plate and got it mounted satisfactorily with it's new joggle.

Once the fuel solenoid was fitted I returned to the new meter panel and populated it. All fits rather nicely

John Rudd:
The meter panel looks familiar.... :lol:

Nice job.. :bow:
