I am now 5 years into the revival of my 1949 2R5 truck. It has been driveable for 2 years. My suburban development is large enough that I can put around 6 miles on it without repeating any streets, so I have been driving it around the neighborhood as a novelty. I took care of some administrative requirements, so I am now venturing outside of the neighborhood. I can go far enough to suit me on 35 mph roads, which is good, because 35 mph is all I can tolerate on my date code 1977 tires.
I have noticed a few things that I am not sure what, if anything, to do about.
1. In second gear the truck will not go faster than 20 mph. It makes no noises; it just will not go faster regardless of accelerator position. Is this normal? I count around 4.5:1 for the differential ratio.
2. Our area is completely flat; the only inclines are on overpasses. For the one on the 35 mph road near my house the engine pings on that incline until I drop speed to around 25 mph. I made one trip over and back at 20 – 25 mph. On the next trip over I bought 10 gallons of premium fuel, and the engine did not ping on the return trip. It seems odd that I would need premium fuel for this truck with this differential ratio. The cylinder compression readings, 1 thru 6, are: 140, 145, 145, 145, 145, 110. This photo is of the timing mark setting. Is there something else I can look for, or is this condition normal?
3. I must slow to around 5 mph before I can shift from 3rd to 2nd without grinding 2nd. Also, 2nd falls out as soon as I let off the accelerator. Are these conditions normal?
Thanks.
I cleaned up the gages and painted the gage cluster cover. The remainder of the interior trim had been painted a brown before I bought the truck. I found that off the shelf Rustoleum item 249032 Gloss Khaki looks like the color that I see in photos of other trucks. I painted the glove compartment door to match the gage cluster. Both pieces look nice now.
I have had a lot of help from this forum. Thank you all.
