The engine serial number in my project truck indicates that it was manufactured as a 1954 model for an automobile with a Powerglide transmission.
The dipstick has no tube and measures 9 3/16" from under the washer to the tip.
When I look at the Master Parts Catalog, I don't see any dipstick that is that length.
Also, I would think that the tube not only raises the seated height of the dipstick to make it more convenient, but probably also keeps oil from seeping out around the loosely seated dipstick.
It seems that in the 1929-1954 Master Parts Catalog, Group 1.516, "ROD-TUBE, Oil Level Gauge, is where I should look to find the part numbers of what I need for this engine. If I am doing this correctly, it seems that part number 3701556 is the part number that should apply to the Dipstick and part number 3686789 should be the tube for the engine I have.
In reviewing threads at
https://www.stovebolt.com/ubbthreads/ubbthreads.php/topics/1577113 and
https://www.stovebolt.com/ubbthreads/ubbthreads.php/topics/656865/261-oil-dipstick, I see that others have had similar questions, but after reading them I am still confused.
At this point, I think that the dipstick or "Oil Gauge Stick" should be Part Number 3701556 and that it should be 15 3/32" from under the washer to the bottom.
I thought I had it nailed down with the Tube being Part Number 3686789...but then I saw an image from the Parts and Accessories Catalog of 30 Oct, 1962 in one of the above threads that indicated the tube would be Part Number 3705397.
If any of the above part numbers are correct, is there a source for these? I have tried to find them online and have not had any success.
As Otto Skorzeny and Jon G have pointed out, one way to set up an unknown dipstick is to add oil and mark where it tells you for one quart low and for full. But if I can find the correct tube and stick, I would prefer to go that route.
Thanks!
