Alright so I am new to working on my WD45. I just got it a couple of months ago. It's always been a little tricky to get in gear especially 2nd and 3rd. When i have the clutch completely pressed it wont go into gear (most of the time). If i float the clutch to about half way they will click right in. No grinding or anything. 3rd is definetly the hardest to go into gear.
Also if i am driving along in 2nd i can push in the clutch and shift to 3rd while it's still moving and it doesnt grind or skip a beat. same goes for 1st to 2nd (Basically shifting it like a manual truck)
I am talking about the foot clutch on everything of course. Is there anything i need to check on it or is this normal for a 45. THe clutch doesnt slip and it doesn't try to walk when it's in gear and the clutch is pressed in.
thanks

| that is standard for any non syncro manual transmission. You have to float the clutch to line the gears up so you can shift it. No worries, drive on. |

| Kevin is right on. Also, I'd recomend NOT shifting gears while on the fly....good way to create problems for yourself. |

As Kev said be thankfull it shifts that way, it means whoever owned it before took care of it and your shifting collars and gears have nice sqaure dogs on them. I just had to fix one that easily went into 2nd and 3rd,, and easily popped right back out under load. |

Shift mine from 2nd to 3rd like that all the time. Never grind. downshifting you need to stop for though. ------------- German Shepherd dad 1957 Allis Chalmers WD45 #WD234847 1951 Allis Chalmers WD #WD88193 |

| My understanding of late Wd and WD45 transmission were built with helical cut gears. It was AC try at making a synchro-mesh tranny. It would never be confused with a Muncie. That said until you have gone through the problems that occur in the transmission top you may think it is indestructible. It is not. Treat that shifter with respect or you could find yourself out in the field with the shifter out of the top and you trying to look into the hole with a flashlite. |

| I have an AC 175 that does the same thing. The transmission is a constant mesh, collar shift arramngement ..much like the wd-45. I bought the tractor new in 1980 and typically put the power driector in neutral when shifting gears... when shifting like this the "collars" move around freely... and shifting into 2 or 3 from reverse is uneventful... just requires another step... but then I don't grind the collars or have to wait for things to line up while releasing the foot clutch. |

| So can you shift on the go or not?I've heard both sides, it's ok to shift on the go, and never do it. I did it on my CA once from 2 to 3 at low idle, and it worked fine and kept right on going. But I dont want to do any thing to tear it up. And also can you shift using the hand clutch on a WD? Thanks |

When I have a problem shifting into another gear, I find it helpful to throw out the hand clutch AND use the foot clutch. It'll go in gear a little easier without grinding that way. |

| I have always shifted with the hand clutch when needed. Like when you are bushhogging and need to back up. You won't grind a gear if done right and I've done this all my life. Never had a tractor that would jump out of gear either. If you don't shift with the hand clutch in certain situations, you've just eliminated your live power. You might as well have a M farmall or 8n Ford. |

Thanks guys i appreciate all the help. I was just making sure she was ok. I really like to take care of my 45 since it's so near and dear to me i always try to fix something thats wrong fast so it doesn't compound into something much worse. I will def not shift on the fly anymore. I never have before... i was just trying to get in gear and it worked so thats why i started doing it. not anymore though!!!! ------------- 1954 CA, 1952 WD with Freeman Loader,1955 WD45, 1963 D19 Gas, 1984 620H, 1980’s AC Forklift, 66 All Crop Harvester, White Top Roto Baler, Misc S.C.
