Hi All! So, working on the WD project, she's running, took her for a drive. All seems to be working nicely with EXCEPTION of 2nd gear... When I put it in 2nd gear, it 'feels' normal, but when I roll forward a little bit, it kicks it out of gear... and if I HOLD it in, it 'bangs' on the shifter like... well... I dunno. But it doesn't like 2nd gear. Is there any wisdom available on this condition? if so, lay it on me! |

Do not use second gear until you get it fixed. Can't tell you much about what to do without knowing what transmission is in the tractror. Late WD's had a curved shifter with the constant mesh tranny developed for the WD45.

Yeah, there's no real risk of operating it in 2nd gear betwixt now and then... it simply won't. It's not knocking like a broken tooth, it literally kicks the shifter out. I'm wondering if there's a bent fork in there... All other gears are working nicely, as do hand and foot clutches. What'd be the popular first step- pulling up the shift tower and looking down from the top? If I do, does the shifter need to be in any particular position before doing so?

If I remember right you put it in 2nd gear or reverse to remove and install cover. 2nd gear is the one I used to put it in. Take a look-see.

particular position before doing so? Still don't know what transmission you have????? Straight shifter or curved?? ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

Don't pull the whole shift tower as a first step! Pull the shift lever out of the tower first, it is a much simpler operation. You can tell a lot about what is going on by looking down the hole that the shifter came out of. My guess is that you have a problem with the detent balls on the slide rails, a worn/bent shift fork or even a bad gear. Use a large screw driver to shift the forks back and forth and observe the good parts vs any worn parts.
And. like Charlie said, it makes some difference which transmission you have.

I have 3 of the gears that go in a straight shifter trans that are N.O.S. One of them is the input, one is the cluster gear, not sure which the 3rd one is. It's either 1/2 or 3/4. I'd make someone a good deal on them. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."

Dave, if you have a curved shift lever, tranny uses the newer style constant mesh gears. Same type of tranny that you read about on here with "won't go into gear" or "jumps out of gear" issues, usually with a CA or a D series tractor. If it's a straight shifter, the tranny uses the older style gears that are pretty much bullet-proof....and the issue is most likely a shift tower problem. ------------- WC, CA, D14, WD45 |

Sorry for not specifying- I didn't know there was a difference... After exploring my IT manual, I didn't see any indication of uniquity... This is a straight shifter- straight up out of the transmission....  With an interesting, but I'm thinking aftermarket shift knob... |

Do like John said, take a look and see if anything looks worn. If you can't tell what the problem is by pulling the shifter, pull the cover and have a look.
