This was bus maintanence day. Up until now, i havent' really done much of anything with the bus since i got back from the big trip.
For the past few thousand miles, i've been having a problem with the "low oil pressure" light and buzzer coming on when the bus is at idle. Today I installed a new oil pressure guage. Of the original guages on the bus, only the spedo, amp meter, and air pressure guages still work. The fuel guage was the last to go, it quit working in nebraska or colorado.
I also changed the oil. The past two oil changes i used mobil delvac. Prior to that, the bus always used rotella. I reverted back to the rotella for this oil change. The low oil pressure problem seems to have disapeared. At idle, the guage reads ~15 psi, at high speed, the guage reads between 70-90 psi.
Another big problem the bus had was it's incredibly slow top end speed. When i first purchased the bus, it would cruise between 57 and 62. The past few months, the bus would only cruise about 50. Recently, the bus was moving closer to 47. I found a solution today. One of the pieces of throttle linkage was nearly disconnected. All i had to do was tighten the nut with a 7/16 wrench and now she's all better, once again cruising near 60 mph. Geeze! why didn't i do that 7,000 miles ago?
I also installed a manual shut off lever inside the cab today. In san fransico the original electric solenoid quit working. From then until now, i just used a bunji cord to keep the engine running. Now she will keep running even if the bus looses all elecrical current. The international buses from the same year as mine already have a manual handle. Ford just tried to get fancy with the electric solenoid.
