The small round depth control on the dash will be surplus when the MFD gets installed so it will be removed.
The existing volt and amp meters will be surplus and will be removed. The following will remain as they are;
- start button
- stop button
- oil pressure
The blower fan does not work. This could be period correct but someone has definitely reworked the pipe in this area so I suspect this was installed (or reinstalled) more recently. I have mixed feeling about what to do with this – if anything. A blower is not needed so much in a diesel engine compartment as it is in a gas engine compartment – but it is still a benefit and is probably required. I will probably remove the existing blower fan and install an elbow in its place. I can then install a modern blower fan on the bottom of the pipe. In fact; I can install a fan on the bottom of each of the two vent pipes with one fan blowing air in and the other blowing air out. I guess the fans would have to be brushless or otherwise not create any kind of spark. I think modern blower fans are built with this in mind.
