Anyone have a shifter pin laying around that they could take some measurements with calipers? I've got a WD45 with a shifter that can be rotated any way that you want. I haven't pulled it out yet, but I assume the pins are in the bottom of the transmission. With a few dimensions I can whip a set out of the lathe.
Thanks, Aaron

You can buy oversized pins from AGCO and then grind them to fit you worn out shifter.

Aaron, Yes what Mack and the doctor mention. I tend to build them to fit. I had to customize the head shape to fit the slot in the shifter ball. till you pull it apart you wont know how bad things are. Yes a broken. worn or missing pin can cause the shift lever to be all over but there also may be many worn areas in the lever, the seat and even in the shifting forks. It is a pain to take the shift tower off but most of these tractors are in need of some love in the shifter area. Age and abuse and normal wear for 65 years may need attention. Several threads on here about repairs to bring them back near spec. Regards, Chris

One of the slots in my lever was badly worn and not straight. Took some welding/grinding/fileing to get it fixed.

All,
I appreciate everyone's input. I will examine the situation once I get it torn apart. I would still like some dimension so that I have a starting point. Reading various sources the pin diameter is .250" and the standard size square head is .325". What I don't know is the overall length and the length of the square head.
Thanks,
Aaron

IIRC the width of the head was about .25 and maybe the length was .325? If you called Brenda at Sandy Lake (as an example of a dealer) I bet she could give you dimensions?I just took a hex head bolt (.25 dia) and ground the sides of the head to fit the slot, and cut the length to fit also. the length can stick out the hole/s. Regards, Chris

You will need to start with a bigger bolt and redrill the pin hole. It will be sloppy in every direction. MACK

Drill out the hole straight, and continue on through the other side for a second pin and cut second groove in ball of shifter.
While at it, check the gates and weld up the end of the shifter to fit the space better so it doesn't have a chance to slip through the gates.
On one shifting tower, it was worn pretty bad so added a stainless steel washer under shifter ball and concaved it to fit between the wear of the tower and the ball... hold-down washer and snap-ring were then a snug fit.
Shifter never felt loose after that.

There should be some info in this link that will help; https://www.allischalmers.com/forum/wd45-shift-tower-details-picture-heavy_topic169724_post1425001.html?KW=shift#1425001" rel="nofollow - https://www.allischalmers.com/forum/wd45-shift-tower-details-picture-heavy_topic169724_post1425001.html?KW=shift#1425001 I'd get those pins from Rick wile the getting is good!
When I did mine, it was and still is a single pin model. I used a reamer to get a nice fit on the tower and built up the slot and filed to fit the oversize pin. Works great!
