Hello, I don't have an answer to your question, but I can point you in
a great direction.
There is a discussion forum at the Yesterday's Tractor Co. website that
is dedicated to Farmall tractors. There are several hundred Farmall
tractor owners who post there everyday - it is a very busy forum!
Anyway, there are quite a few people in the forum who are very
knowledgeable about anything Farmall. They check daily for new
questions from people, so you might want to ask your question there if
you still need help.
To get to the forum, go to the following URL:
Once there, under the "Cummunity" section in the left hand column,
select "Discussion Forums". From there you will be presented with a
list of forum links - select the one for Farmall / IHC Tractors.
If you need parts or manuals, the link to the store is:
Good luck with your tractor!
