Welcome to my plan B. The Olympus electrical connectors when in transport are held in place with open ended blanks, these were removed from the harness and attached on to a diecast project box, this box in turn has some standard Canon ITT circular connectors mounted to it and will be used for all required electrical connections.

The diecast ‘terminal’ box awaiting it rear mounted plugs. I have also added feet on to the box so it can be secured to the Olympus frame.

The terminal housing now secured to the Olympus frame and the engines control wiring secured to the original blanks. This leaves the plugs terminals exposed inside the box ready for patching.

This engine is large and it would fully fill my workshop, I don’t like it being outside so I took a punt and bought a small event marquee to store it in, that night we had the worst gales in 10 years which destroyed the marquee, a bit of a low point for me.

It’s time to start thinking about how I am going to mount the engine on to a lorry, all vital parts were stripped from the frame where possible and given a brush down and a bit of a clean. Pictured below are two of the four mounts that support the engine.

A total of four cross beams will support the engine, pictured you can see two of them with the rubber mounts in place.

On the underside of the cross beams I have welded spacer rings so that when bolted down all is secure and play is reduced mainly due to the rubber mounts.

As I don’t have a Tele-handler, I had to resort to making my own lifting device, a design was drawn up by my friend Will Parry and he also had all the parts required plasma cut by his colleague Craig. A few days fabricating and I have a working Gantry, this is all considered part of the Olympus project.

I bought a 7.5ton lorry which is just capable of transporting the weight of the engine and all is fine and dandy, it passed its motor test first time which was a relief.

As I am now able to access the underside of the engine it was time to inspect it for damage etc, it’s somewhat daunting when you first get under there, an awful lot going on.

The fuel blank has now been machined down and threaded to allow a 1 1/4BSP fitting to be inserted (and blanked), this allow a secure and safe method of feeding the engine with fuel.

A 3″ BSP 45 degree bend has been attached on to the air delivery feed making it easier to source required fittings as it seems almost everything on the Olympus is a non standard thread or fitting.

A test actuation on the pneumatic starter revealed a fault so a remove and a strip down ensued.

Hmm, one faulty electric motor and a bit of a weird one. The wires for it come from the front, right next to the output shaft, there is almost no chance of repairing it so I’m of to the internet to see if I can find a replacement, not holding out a lot of hope though.

And would you believe it, I found one on eBay! I can’t believe that it was ex Concorde Olympus stock, so I presume the motor was fitted to other engines as well.

Time to remove the hydraulic pump and pipework that isn’t required. If the pump was left in situ then unless a closed loop oil system was utilised the pump would be driven by the engine dry and this wouldn’t end well, so it’s better to remove the pump altogether.

There are two HP Fuel valves on the Olympus, one of them for some reason is very corroded, although the contacts themselves seem to be in fair condition. The throttle actuator which is located behind it needs to be removed and de-engineered if possible.
