Lots have happened over the last few weeks, sorry only one picture. The window rebuild is complete, except of the engineers side. We did not get the chance to start that one, hopefully we will get to that this summer. The brake stand in 664 was up for it's rebuild, I believe it's every two years. The old one was sent out as a core for new parts. The new fan control install is complete and working, but we ended up having to install two extra relays to get the hot engine alarm and shutter control to work properly. It looks like we will be in the market for another one for the B-unit..... Speaking of the "B",,,,, we have had some off and on progress on rewiring the main cabinet, working on it as time allows. In July we will have a retired NS employ coming up to work with me and complete the job. He feels it can be done in about 20 man hours.
This years excursion season has begun, and a few things turned up with 663 that need attention. Some leaky engine covers, plugged drainage holes for rain water, and the #1 cooling fan was not running. The first two repairs were just a matter of swapping out gaskets and clearing dirt out of weep holes. The last one required a little more work. After some investigating I found that the problem was the contactor for that fan had one set of contacts that were so worn out that they would not close.
In the above pic I have blocked off the #1 contactor in the "ON" position, you can see that the center set of contacts are just barely touching, and the set on the far left have about a 1/8 inch gap separating them. These contacts are easily replaceable if you have an extra joint between your wrist and elbow and small fingers, I have neither. But with a little frustration and language not meant for small children the job got done.
