Gents,
I was a away for a while. Always good to seek the advice from the knowledgable folks here.....
My 1949 8N has been at odds since I have been back in Texas using it. The spark keeps, well, disappearing.
First time it happened I discovered a little round ring by the bottom fan pulley (this would turn out to be the distributor bushing! How this bushing found its way out of the distributor without the distributor being off is an 8N mystery??? I discovered that the little round ring was the distributor bushing when I took the distributor off to check the points. I realized what is was immediately (because play in shaft).
I soon discovered that there was two hairline cracks in the distributor housing (see picture) and, although the distributor bushing was reinserted, the bushing would come out fairly easy.
With a hope, a prayer and consultation from my manuals, I replaced points, inserted the bushing and reattached the distributor. It would not start. I did the old "let her sit a week" trick and it started up on the first try.
I ran for a while and went down. But kind of a sick death....sputtering for several minutes. I thought I lost compression.
Yesterday, I went to do a compression check. Just for fun, I checked sparks first...no spark. I removed the hood and completed the compression check with following results:
1 - 90 psi (rear)
2 - 90 psi
3 - 90 psi
4 - 105 psi (front)
With the tractor having adequate compression (I believe) and the tractor having no spark.....I turned my attention to the cracked distributor....
Can these little cracks be causing the problem? I am assuming that when mounted, there is NO play in the shaft?
How did the bushing escape the first time?
Regarding compression, why was 4 cylinder so much higher than other three?
Oh, and I did a test with the voltmeter and I was getting juice to the coil. I attached a pic of bushing out of distributor to make sure anyone interested in helping knows what I am talking about.
Thanks for your wise comments.
