gwest_ca-(File Mod) 11,190 #2 Posted Monday at 07:06 PM That is the patent number that was on all the Uni-drive transmissions. From the information we have the 512-D had 1" axles using transmission model 110996. Click on the first picture.

Gilou15 9 #3 Posted Tuesday at 01:40 PM (edited) Bonjour! Merci pour les réponses et les documents ! J'ai donc annulé l'achat.! Car je préfère les transaxles plus costauds et je ne comprends pas pourquoi WH a fait ce choix pour un tracteur Diesel (cher) en 1986 alors qu'en 1979 il équipait une entrée de jeu comme le C101 des transaxles à huit pignons full size ? Je ne pouvais pas imaginer cela ; En outre : il est plus économique de fabriquer un seul type de transmission.... Vos avis !?

gwest_ca-(File Mod) 11,190 #4 Posted Tuesday at 03:06 PM Because I prefer stronger transaxles and I don't understand why WH made this choice for an (expensive) Diesel tractor in 1986 when in 1979 it equipped a starter like the C101 with full size eight-pinion transaxles? I couldn't imagine this; In addition: it is more economical to manufacture only one type of transmission.... Your opinions!? Share this post Link to post Share on other sites
lynnmor 7,509 #5 Posted Tuesday at 05:45 PM The diesel had less horsepower than many gasoline engines. The reason for a diesel is fuel economy and in years past was cheaper by the gallon. There is no magic but many point at torque but that is taken care of by gearing if necessary. Share this post Link to post Share on other sites
Blasterdad 2,840 #6 Posted Tuesday at 10:10 PM If your tractor has 1 1/8" axles you should have this 8 pinion transmission. Some models....(Toro lists this model as using the 110996 with 1" axle 4-pinion differential which is wrong) 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,190 #7 Posted 21 hours ago (Toro lists this model as using the 110996 with 1" axle 4-pinion differential which is wrong) How did you determine this? Discovered one transmission page was missing from the ipl but found where Toro got the info for the manual. Have added the missing differential illustration between page 5 and 6 and deleted the first manual we had. Revised ipl 1 Share this post Link to post Share on other sites

It's one of the footnotes in the file I uploaded, 1990 312-8 model 31-12K801 - Toro lists this model as using the 110996 with 1" axle 4-pinion differential which is wrong. I know that doesn't apply to the 512D, I was merely trying to assure @Gilou15 that he had a good transmission & not to worry. Share this post Link to post Share on other sites
Gilou15 9 #9 Posted 19 hours ago I always can buy it if I am sure about the type of the transmission Can you show me the document where it is exactly specified the transmission for 512D ? Thanks Share this post Link to post Share on other sites
Gilou15 9 #10 Posted 19 hours ago On the user Manuel the hubs are 1"1/8. The tractor I would buy is far and I cannot measure myself and the seller is unable to measure correctly !! What can I do to be sure ? Share this post Link to post Share on other sites
Blasterdad 2,840 #11 Posted 18 hours ago Is there something wrong with your transmission? Share this post Link to post Share on other sites
Gilou15 9 #12 Posted 17 hours ago No no problem but I would buy this tractor only if it is equipped with eight pinion diff , I only want this transaxle . I think if WH did it , there was a good reason !! Share this post Link to post Share on other sites
kpinnc 13,233 #13 Posted 16 hours ago 12 minutes ago, Gilou15 said: I think if WH did it , there was a good reason !! Not necessarily. Wheel Horse was notorious for clearing old parts inventory by introducing "special" model machines. In addition the 512D was an export model as well. Not surprising that the typical domestic rules weren't followed. Share this post Link to post Share on other sites
stevasaurus 22,986 #14 Posted 15 hours ago This you can count on...if it has 1" axles, it IS a 4 pinion differential. If it has 1 1/8" axles, it has 8 pinions in this case. Share this post Link to post Share on other sites
