So here goes. This will require the removal of four bolts from the pan under the genset. The bolts are at the 4 corners. Soak them with penetrating oil and leave them to loosen. Soak the bolt on the electrical connection also.
The exhaust needs to come off. Soak the bolts and then loosen and remove.
While those bolts are soaking lets have a look at our quarry. You can't see it from the front of the dirty beast
You need to look up over the top and in the rear.
Disconnect the battery either house or chassis depending on how yours is set up. Now remove the bolt and disconnect the wires. You can now pull firdt the wires then the harness out through the hole in the side.
There is one cable that is fastened to the case side and comes in under the electrical section where it cannot be seen. There is also a fuel line that can not be reached or seen. I may have to wait until I lower the case a bit to get access. They did not leave enough slack to drop it with the cables intact.
