I am in the process of installing new hubs on a Case IH 275 MFD 4 wheel drive tractor. My tractor was built by Mitsubishi and badged as a Case and use the same or very similar front drives. <br>
My question concerns the pinion or king pin shaft that drives the front wheels, part #1962152C1. The splines on one end have a stop that prevents the gear from moving beyond a point on the shaft. The other end does not have this, the gear can move all the way to the bevel where the splines taper to the shaft toward the middle.<br>
Should the end with the stop on the splines go to the top or to the bottom of the spindle.<br>
I can send pictures if it helps and any help would be greatly appreciated.<br>
Thank you in advance,<br>

Hello all,<br>
I am trying to figure the simplest way to set the lash between the ring and pinion gear in the final drive housing located at the end of the front axle on a Mt300D or any of the variations that use this front drive,d1650fd,d1850fd, d2050fd. The method is probably the same for any of the machines that use this type of gear drive.<br>
My manual gives the tolerance and obvious instructions but fails to tell you where to measure the play when replacing only the gear housing. Further details are outlined in a rather confusing manner for setting lash when the entire spindle is removed from the axle shaft, but I don't need to remove this assembly. The lower gear housing os a week link on this machine,has anyone done this job.<br>
Thanks in advance.<br>

No sir,
I have a line on some of the parts and thought I had the gear case secured until we found that the item was mismarked. Until I get my hands on them I will continue to search for them.
The lower gear case broke at the lower bearing housing taking with it the lower bevel gear, ring gear, and associated bearings, seals, etc. Apparently Mitsubishi has stopped making this part and they are onle available from salvage. I had hoped to find a complete unit or swap the front drive out with one from a similar machine, but can not determine a compatable donor.
The Case IH 275MFD is the same as the Mitsubishi MT300D and the Mitsubishi MT301D. There are probably some Satoh models that are the same but can not find info on them.
If I do come up with the parts, I will let you knowwhere I obtained them and how much I had to pay. I may try to repair the part, but there is a great deall of stress at the point of the break and am not sure the repair would last. I'm not sure it the case is made of cast steel or cast iron. The material of the casting makes a big difference on the strength of the repair.
Thanks

Thanks for the help, these tractor were not that popular here in the south east, but I will post a message on craigslist as per suggestion. Sorry I did not have a chance to respond earlier. Who knows, gramps may have one under a tree gathering moss, or it may pop-up on a google search. I appreciate the phone number for Mullins, I will call ASAP.
I will let all know where I eventually find parts. It's tough knowing you could easily repair your tractor if parts were available.
Thanks
