66 series hi low shifting

[756puller]

My dad has a 966 he lost high and low range in. It still has reverse. My bet on what is wrong is the shaft that the high low shifter rides on.  Memory serves I think don't you remove the 3rd link cover to remove/install shaft by reaching clear across the rear housing?

Check the external linkages first.

Yup , remove the small cover below the steering column and see if the linkages are moving

My brother already checked where the linkages hooked up and they were moving.

I believe you need to pull up the deck and remove the range cover.

Honestly I suspect the roll pin that holds the shift arm to the high-low fork shaft sheared off. The cover will still have to come off because the shaft no doubt dropped down into the range housing.

[756puller]

Yes I know either way the range cover has to come off I was just trying to jar my memory if the shift for shaft was able to be pulled out from the back.

Yes it comes out the back. If that is your problem it probably is the single E clip style. Upgrade to double wire C clips. Check fit before installing. May have to grind fork to fit between clips. Chamfer holes so it forces ring into groove.
