cat 906 Rear differential gear set

i am having a hard time finding the rear differential gear set for my loader as the splines have striped out , i have contacted my local cat and there no help they want me to buy a complete rear end! so far from what i gathered i need part number 2295626. i have ordered these from us parts locator 2 times receiving the wrong swing of gear or wrong number of teeth can anyone help i will attach images

I depends on whether you've got a limited slip diff or not, but a quick and dirty check and I can't see a problem. It breaks down into a bevel gear set and an installation kit.

Couple years ago I worked on a few 908Gs and they had that same problem and the reason you had to buy a complete differential was because it was an update to prevent that problem from reoccurring.

As per Cmark's signature line - what's the machine Serial Number..? According to me 229-5626 is the complete assembly, the differential bevel gear and pinion (only available as a set) is 218-4692 - and it's indicated as "Not Available". Edit: There is a new design of pinion available for the rear axle differential that appears to be an attempt to cure the issue of stripping splines from the pinion shaft, exactly the same problem you have experienced. That probably explains why the former parts are no longer serviced. To go further requires a Serial Number and whether the rear differential is the open type or limited slip.

CAT 906 Pinnon/DriveShaft Splines stripped Hi Guys Just reading your comments there on your issues with the splines stripping. I have encountered the same issue and have been quoted serious dollars by my local CAT dealer for parts....currently it is off the road and in my workshop! My machine is year of Manufacture 2002 and I have owned it since brand new. I now have 6000hours on it. Should it have been part of a recall if this was a known fault? Would you guys have a line on cheaper replacement parts but still up to the same standard or better?

What's the Serial number ..........???? The likelihood is that there will be nothing available parts-wise in the aftermarket field for something like a differential. What Part Number is the Cat dealer quoting you and how much are they asking..?

The former parts are no longer officially available. Why use parts that are known to have a problem when updated ones are available..? The new pinion drive shaft is part of new oscillating axles, new differentials and new transfer drives. The new pinion drive shaft and the new differentials are adaptable back to first production for the listed machines. The former oscillating axles and differential groups have been cancelled. When the necessary new parts groups are installed 284-3874 Rebuild Kit must be installed at the same time so that the transfer drive will connect correctly with the new differential.

It's a very common issue. We've repaired it twice on out 908, there were 3+ updates so make sure you get the latest and greatest. Make sure to rebush the trunnions, we had to buy a whole differential assembly and the new drive gear for the drop box as mentioned above. The differential assembly ( not an entire axle assembly) was the only option as the whole unit was updated. Don't forget to order new planetary seals as they need to come off to get the axleshafts out.

Sometimes us po folk gotta do what we gotta do... sigh But yes, should do the update to do it right. Here's the Rebuild kit availability: http://www.machinerytrader.com/list/partssearch.aspx?partnum=284-3874+ You can also buy through http://www.offroadeq.com they pull from the same warehouses.

Click to expand... I cant find part ## for the middle coupler, can you help?

Maybe, but post a Serial Number for a kickoff…… Read some of the replies above. Do you see a pattern.?

Serial # 6ZS01101 3NM05143 . Have new rear diff and transfer kit but did not come with middle coupler

Is it Ref #5 in the illustration below.? If so the Part Number is 154-8545, Flange.
