I got my AC WD stuck in reverse and the gear shift

Basically I went to put it into reverse, but you have to throw both the hand clutch and push the foot clutch all the way down to shift (don't ask me why; I have no idea - but it works)... But as sometimes happens, the gear starts to knock because it's not slowed down to shift yet, so I let the stick go. But it locked into gear, and as I moved the stick around it now has a complete range of motion and won't catch any gears at all... Nevermind the fact that it is in reverse.

I see I'm not alone in this problem, but perhaps I'm alone in that I'm just 18 and only driven my tractor for about 100 hours. And all I've worked on myself is the alternator 12 volt conversion, oil filter and oil and all that stuff, and places to grease... And moving the draw bar. But other than that, I have no experience on how to fix the shifter.

I hear people say you can take the stick out and take it out of gear, and put the stick back... But I don't know how. I know if you take all the bolts out and remove the shifter; then that creates a bigger problem because that's the gears themselves - not the shifter. This isn't the first time this has happened to me (2nd, actually), but the last time I was about 14 and got my mechanic cousin to fix it for me [he told me it was like a 5 or 10 minute fix].

But I'm on my own, and it's out in the field, and I was wondering if I could get some detailed instructions on what can be done. And if there's an quick fix I can do so maybe it doesn't happen again?

Like, is there a pin that comes out to remove the shifter, or do those two metal rings get pried out or what? It's a crooked shifter (well it was, but when my cousin fixed it the last time he chopped off the bend in it so it'd shift easier - because the "turning" dislodged it). But this time, I'm up the creek, because I don't know what tools I need or how exactly to do it...

Help. Please!

I don't know why, but I can't seat the two washers and the snap ring back in the tower.

Unfortunately the two people helping me bent the inner washer and have rendered it completely useless... And I don't really want to order a new part at this juncture.

So is there some sort of temporary fix I could do to hold the shifter in place - since I KNOW it will slide out on me again when I put it in reverse sometime?

Check with a dealer or parts house for MACHINE WASHERS. Various thicknesses, bores, and diameters. Bring your exising good one in for a sample size and stock up on some extras.

Well, I've left the shifter loose for the time being. I've been able to use every gear so far, but I haven't tried reverse yet, since I figure it'll just slip out on me again. It's a pain for hitching and stuff, I really need to get a mechanic to look at it and my right rear wheel that grinds a little and pops.

Is there any major danger in doing this?

Ok since all the other people like to tell there own storys on here instead of helping with your problem.... Remove steering post and any other parts bolted to the shifting tower. Unbolt the whole tower from the base of the transmission. Pull straight up on the tower to remove it. The gears are now exposed. You will understand the next part when you see it ok. Move the gear clusters back to center. It is obvious when you have them in the correct postion. The shifting lever itself will fit perfectly striaght back down into the center of the gear cluster. Bolt everything back into place. Seems like a big deal and it is not. I had a WD that stuck into 2 gears at once everytime. The end of the shift lever could be worn or the detent balls can be getting worn. Detents are very hard to get in and out. Almost impossible. Any questions write back.

 UPDATE (can't re-align gears yet...) [help] in reply to Diesel Cowboy, 07-17-2005 17:37:45  
I'd prefer to not have to remove the gear housing if I didn't have to... All I did so far was pull the snap ring and the two washers. The stick pulled straight up and out with some force; and the square pin never even came out. It's still in there.

I can see that the reverse gear is indeed misaligned, but the tractor was parked on a bind and wouldn't release the gear. But by the time I backed it to the house after failing to move it, it was nightfall, so I will try again tomorrow. If I try again tomorrow and the gear releases - and I can reseat the assembly - I'm home free.

If it won't release, is there some way I can "help" it free? This is what I see when I look into the tower the shifter was in with a flashlight: (image size is like 5 KB, it's black n' white)

Link

What bothers me is that little black box I drew in there is a piece of metal... And I assume it's supposed to be there. I assume only though. I don't know if it needs to be pressed down and then I need to pry the gear over or what.

You mention backing it to the house- that means it is not stuck in two gears- it is in reverse and the shifter is out of the forks. My previous advice still applies- you need only to remove the shifter and align the shift forks. Granted, the bottom of the shifter still needs to be rebuilt, and maybe the top of each shift fork needs to be built up. But at this stage you do not need to remove the battery, battery box, cables, steering wheel support, shifting tower, etc. It is much quicker to remove the shifter and align the forks. You mention a piece of metal- there is a small piece of metal inside the tranny, I think it is on a shifter fork, but without my manual here I cannot ID it or tell you where it is or its function- but I know that it belongs there. I tried twice to access your link but it would not show up. The curve in the shift lever is not the problem- the WD45 was easier to shift than the WD. The problem is likely to be on the bottom of the shifter- and if you rebuild it by welding and grinding- the angle of the wedge at the bottom is NOT parallel to the angle of the top of the shift lever. Compare it to a new lever.

I'll try again tonight after work to see if I can get the forks to realign. Reverse was stuck (tractor was parked at bad angle) where it was originally, so maybe I'll have better luck tonight.

I'll report back later. Glad to know that little metal knob is SUPPOSED to be there though (and that it's not a piece of the shifter).

You mention a WD and a curved shifter- if it is indeed a late WD with the 45 transmission- the curved lever should have two pins- opposite each other. If it is an older WD tower and you install a curved shifter with two slots, you can drill through the existing hole, to the other side, and put in two pins.

It's a 1952, so I figure it's probably one of the first they had with a crooked gearshift. My grandpa has a 1953 and it undoubtedly has the 45 transmission in it.

Though I used his old 1948 (I think?) WD with a straight shifter, and I don't know how that thing would ever come out of gear it rolls so smoothly. I really do hate that accursed crooked shifter though. Which I took care of on mine, since the top was done in anyway.

You do not need to unbolt the tower to get the tractor moving again. The problem is the square knob at the bottom of the shifter, and cutting off the curve is not going to improve that- it needs to be rebuilt by welding metal on it and grinding down to proper size and shape. The top end of the shift forks may also be worn and can be rebuilt, but that involves removing the tower. To get moving again- do this: remove the rubber boot on the shifter. You should find a snap ring and a washer under that. Remove them, and the shifter can be lifted up out of the tower. Be careful not to lose the square pin in the side of the tower that goes into the slot of the shifter. Take a long screwdriver or pry bar, and with a flashlight, look down into the tower. One shift fork will be out of line of the other two. If the tranny is stuck in reverse, it will be the left-most fork. Pry it back to line up with the other two. Replace the shifter, being careful to align the square pin with the slot. Replace the washer and snap ring and boot. Learn to let the gears stop turning completely before trying to shift- that's a big reason why things wear and jam. Don't expect to shift using only the hand clutch- that is not what it was intended for. In the future, if you remove the tower, you'll find it easier to replace if you move the reverse gear and reverse fork into operating position before replacing the tower- in other words, do not have it in neutral. The reverse fork arm will go around the gears easier if you do this.

Ah, I'll give it a shot in a few hours, and see if I can do it. It makes sense to me, though.

Actually, I don't shift with just the hand clutch, I have to push the foot clutch all the way down - AND throw the hand clutch - and wait at least 10 seconds to shift or otherwise it bumps and grinds. I try and be very careful with it, but I must've turned it in just the right (or wrong) way to make it come out.

Thanks for your help.

If I did anything more with it than pull small logs, a trailer, and a rotary hoe... Then I'd probably invest in getting it all rebuilt. Or maybe I can pick up some mechanics & welding classes in college and try my hand at it in a few years.

Thanks again!

JNS has it right. I had trouble with my WD (straight shifter) and I built up the end with weld and reground it and no more problems. My WD-45 is a different story. Fixing the shifter didn"t do it. Looking down into the tower, I can see the rails are worn real bad and one looks to be bent. I have another tower which I"ve got to look at; hopefully, it"s a little better. BTW, if you"re using hytran oil in you tranny rather than the 90 WT gear oil, the gears are much more prone to clashing. Even with 90 WT oil, the gears in my WD will clash some when the oil gets hot. I found that throwing the hydraulic lever up for a few seconds will bring the gears to a stop. The design of the late WD and WD-45 tranny is such that it is much less prone to clashing.

I'm fairly sure that all the parts are worn to a horrid degree in my tractor, but reverse is the only gear it wants to slip free from... I really wish I knew how to weld worth crap.

What do you need to do exactly, weld some extra metal on the bottom and then grind it down?

Yes- A new shifter has a tapered, four-sided bottom to it. When you look into the tower, if the three forks are lined up and have about the same dimensions on the open slots, building up the shifter may solve the problem. If not, you need to pull the tower and work on the forks as well. It's a trial and error thing- on the WD45 I just did, I had to refit several times and keep grinding on just one side to get the lever to move far enough to move 1st and 2nd. If the pivot ball on the shifter is worn you may need to add shims under the top washer to take uup slack. The snap ring should hold things in place with no vertical slop. Lube that ball on final assembly and keep a rubber boot on the shifter.

I do have a brand new rubber boot on it, and there is no vertical motion to the shifter (when it is completely installed). The shift forks themselves are not bent, but appear to be a little worn. The shifter bottom is VERY worn though... I tried to get the gear free with a screwdriver and was bending it too much. I'm going to move the tractor a little and try later with a pry bar.

What causes the gear not to shift out, if you offhandedly know? Sometimes I have to roll more in one direction to get it to go in or out of a gear; even with a fully depressed clutch.

Just guessing that the gear might have so much internal wear that it gets cocked on the shaft when it engages the adjoining gear. I've never had one that was difficult to get into neutral.

Undoubtedly, that is it... But it's odd I couldn't even pry it loose.
