Ford 2000 7 speed transmission

Hi. I have a Ford 2000 1966, 3 cylinder diesel with 7 speed transmission that was made for German market.

As I understand 7 and 8 speed transmissions are the same but on this 7 speed transmission the 4th high speed is blocked by a shaft that connects the high/low shift shaft and the 4th speed shaft so you cant engage 4th speed while transmission is in high range.

Does anyone know how do I unblock the 4th gear when in high range (how do I pull the shaft that blocks it out)?

Thanks!
 
The plunger shown in red needs to come out. From the image, it looks like it might be as simple as removing
the bore plug on the LH side and pulling it out with a magnet. If that doesn't work, you might have to pull
off the shift cover to disconnect the 4th gear fork from the rail to allow said rail to be pushed farther
ahead to get the needed clearance. I'm not certain because I've never worked on a 7-speed. As rare as those
trannies must be, ones with the plunger still in them must be even more rare.

I can't imagine why they would do this, was it to limit road speed with solid tires or something, I know some early tractors fitted with steel wheels had road gear blocked out
 
It had nothing to do with steel wheels. It likely had more to do with tractors pulling trailers on narrow roads in Germany and similar countries.

Interesting, must be a pretty low road speed earlier ones only did about 18mph not like later ones like the 3910, 2810 etc which ran over 24mph
 
Thanks for replays! Tomorrow I will try to remove plunger that deactivates 4th speed, as you recommended in the posts above.

I measured something like 20km/h road speed in 3rd gear, I hope to gain some more speed if I menage to activate it.

In addition to Ford 2000 I have a Ford 4000 that has the same transmission 8/2 and its 4 speed is activated, its road speed is something like 30km/h but 2000 has 12.4/28 rear tires and 4000 has 13.6/36 rear tires so I presume that 2000 in 4th gear is not going to be as fast as 4000 becuse of the smaller tire diameter.

Boath are measured by google maps navigation.

If you look at the parts pages for the '65-'75 thousand series tractors, the transmission is listed as "DUAL RANGE 7 SPEED (GERMANY) & 8 SPEED TRANS." so it was Germany that had the road speed limit back then, and I think it might have been 25 kph (around 15.5 mph).

Tried this, did not work. :( I could not push the 4th speed shaft enought to get to the blocking shaft.

I am planing to split the tractor this winter to get to that blocking shaft.
 
Hi. Need help again.
Found this snap ring in the bottom of the trans housing. Where does it go? In the second picture you can see it in the bottom where it was when I found it.

This is what I found on the bottom of transmission case. Where does this plunger and snap ring go?
