Identifying LZ gears

[Ggmac]

How can I tell a set of LZ gears from regular Ford sets ? One of my spare transmissions supposedly has them .
Thanks , Gary

What is the tooth count on the large front gear on the cluster gear? LZ’s were either 25 or 26 teeth.

What are normal a Ford gear count ?

There are lots of gears. Gotta go to Mac VP's sight and study the tooth count and application charts

Common main drive gear tooth count is 15 or 16. LZ is 18 or 19. I use the oil hole for reference and can count this pretty quick. Common cluster is 28 or 29 (big end) and LZ is 25 or 26. Harder to count in a dirty, oily transmission. Rule of 44: 15/29, 16/28, 18/26, 19/25.

The standard gears are 16/28 if I remember correctly.

Put a grease pencil mark on one of the teeth of large gear on the lower cluster. Count as you rotate. If it is 25 or 26, you have an LZ gear set.

Correct
