"the guy was supposed to replace sometype of gear break"

If he replaced the tranmission brake with the original style then it is adjusted like the manual shows. If the brake assembly was replaced with an after market version then the adjustment procedure may be different.

The adjustment is made on the right side of the clutch housing. There is a rod that is operated off the clutch shaft. On the rear/lower end is an adjustable clevis that is attached to a lever. The adjusment is made at this clevis.

1) Remove the pin through the clevis.

2)With the clutch held all the way down, push back on the lever, and adjust the clevis so the pin holes line up.

3) Turn the clevis 1 1/2 turns farther out, relea
se clutch, and replace pin.

Check adjustment by running the engine about 1000 RPM. Fully depress clutch. Wait about 3 seconds and you should be able to shift into gear without grinding. Extend clevis out further on rod if transmission does not stop soon enough.

If the brake pad inside is worn out you will not be able to get the tranmission to stop correctly if adjusted like this.

If the rod on the right side is welded to a tube with a gease zerk on it the adjustment is different. This system uses a metalic brake pad and a spring inside the tube in the rod. This style is adjusted with the clutch released. Simply adjust the clevis so the pin can be inserted.
