WD-45 Clutch question

Welcome Guest, Log in or Register

Report to Moderator

I have an Early '45 that I am rebuilding. I have got it running real smooth but the foot clutch is stuck? I can look under the inspection cover in the bell housing and the three fingers on the pressure plate are all screwed up. With the clutch pushed in, only one of the fingers makes contact with the throwout bearing, the other two are almost 1/2 an inch away. The manual I have really makes no mention of adjustment on the pressure plate. ALSO to make it more fun, I have obtained a really nice pressure plate to replace it (if I have to) but it has nine springs on the pressure plate, the one on my '45 only has 6 springs. Will they swap out? or do I need to obtain a new 6 spring type press. plate. Also, any ideas on adjusting or fixing the clutch without removing the motor?

This is my first and only tractor, and I am learning and enjoying (well sometimes enjoying) it. It was stuck, stripped, and every panel dented if not gone. I am almost ready to finish the mechanicals up and paint the old girl. Thanks for any help you folks can give me.

Well I finally decided to tear into the clutch for real. I stripped the tractor down to frame and tires and pulled the motor, took about 3 hours going nice and slow. When I unbolted the 6 pressure plate bolts I had to soak the flywheel/Pressure plate with AeroKroil (damn I love that stuff!!) Anyway the pressure plate was broken where it meets the clutch disc. Actually it was shattered into 3 pieces!! The clutch disc was powder with some metal in it, and the surface against the flywheel was perfect. The flywheel is smooth as can be no damage or burning. I test fit the 9 spring Pressure Plate and a used clutch and it fits perfect!! BTW the 9 spring PP is a massive unit compared to the 6 spring type nearly twice as thick everywhere. While I have it all apart I am gonna blast the smaller parts, grind and strip the rest and repaint it.

Thanks again for all the help John

You can put button clutch in also and would have to worry with slipping.

1 5/16" from the clutch hub to the contact surface of the pressure plate release lever.
1/2" to 1" free pedal travel measured at the top side of the frame channel. Duey

45's had a nine spring clutch while a straight WD had six. Either you don't have a 45 or it's got the wrong PPA. The clutches do swap though. If there is a problem with the pressuer plate assemble(PPA) then I'd pull the engine and have a look. Remember to replace the pilot bearing, throwout bearing, rear engine seal and clutch shaft seal while you're at it.

the straight wd 45 had a 6 spring clutch also..the wd-45 diesels had a 9 spring clutch and they are worth money to pullers so dont let it go to cheap if you dont use it and sell it

Hello thanks for your answers. I researched the archives in the pulling section and found that the 9 spring will in fact bolt right in instead of the 6 spring Pressure plate. I scored it on E bay for $50.00 about a year ago brand new. I have ordered a new clutch disc and release bearing. I understand NO Wd-45's came with a pilot bearing. I rebuilt the motor last fall with it still in the tractor and have just got maybe 1 hr of run time on it so all the rear seals etc. are fresh (I hope) I am gonna yank the motor and install the new clutch tomorrow. It also gives me a chance to install the new hood and front radiator shroud (Ebay again...) While I am waiting for the big brown truck I am going to take the time to clean and paint the motor and all the nooks and crannies. Any tips on doing my first tractor paint job would be appreciated Thanks John

Pulling engine not that bad. Takes about 2.5 hours.Renoving Radiator and sheet metal about half of the job.

Today's Featured Article - On the Road with Dave Gohl: Deere Departed Friend - by Dave Gohl. Have you ever had to part with a dear friend? It's not easy. If it's due to death, your feelings could be in disarray for days, months or even years. Even now after almost 4 years, I still miss my dad. I remember when I was a kid my dad sometimes would tuck my brother and I in at night and we would ask him questions about his childhood on the farm. To this day, it's some of the best stories I've ever heard. And now, I'm so glad that I asked those questions, and if I were a little smarter i ... [Read Article]
