1690 4wd front axle

Post by db995q » Tue Jun 27, 2017 2:46 am

The front axle on my 1690 4wd is leaking oil at a fair rate and im looking for advice on how to approach the large hub nut that requires a special socket to loosen it, i have a torque multiplier to deal with the high torque value but its the special socket required that is causing me problems, can it be got anywhere or is there anything else available that could be used. Thanks in advance.

It can be made from a piece of pipe with 4 square bits of key steel welded into it or something similar

Would it be possible to not loosen the hub nut and just remove the stub axle bearing pin and pull the stub axle housing and hub out as one unit? its the oil seal in the axle housing that is leaking

You will not get to the axle housing seal by removing the hub nut. Removing the hub nut will make it possible to changer the hub seal (see the following link) http://partstore.caseih.com/us/parts-se ... 9ar1297134 . Remove the stub axle bearing pins and remove the complete planet reduction together with the drive shaft.

You could also remove the ring of nuts that holds the hub to the swivel housing to get to the seal

The OP said "its the oil seal in the axle housing that is leaking". To get to this seal you have to remove the shaft that transfers the power from the differential to the wheel hub. The easy way is to remove the complete planetary unit from the axle housing.
