951c - Problem with oil steering clutches

That would most likely be a problem with the pinion shaft seal or the seal retainer just behind the steering clutch brake drum mounting flange. Thats a big job on a loader and best done when it comes time to do some steering clutch work or other combined job

If you can live with it I'd keep doing what you have been doing until you need to go in for major work.

Thanks guys,
I understand, the work needed now is not the case to do so :frusty:
The loader will still work about 500-1500 hours in his life.

What happens if the gears are working with engine oil?
What's the risk if oil rises?
😕

Both responses are correct. Usually an oil transfer problem of this nature, is caused from the O-ring on the duo-cone becoming hard over time. It becomes loose and can no longer do its job properly. In answer to your last question, engine oil can not do any harm in your final drives. Actually Cat used to recomend SAE-30 in final drives. A lot of people also use gear oils, either of these oils are fine. Over filling isn't a big problem, any gear compartment that is Way! over full will run hot, just drain it down from time to time. If your oil transfer happens quickly, and you can also feel a pulsing on that brake pedal, the inner bearing on that pinion will be in bad shape. Hope this helps ease your mind.

Hello,
staycat.inc your answer to me is very helpful.
Unfortunately, the right pedal pulsates when the steering is operated ...
I was hoping would be improved by adjusting the pedal but it is clear that this is not the problem.
Now I can not disassemble half loader, I do not have enough money ...

If the brake peddle is pulsing you have more than a seal problem. There may be a problem with the pinion shaft bearing at the drum end or the retainer bolts are loose and wallowed out (not uncommon).

As far as what oil to run, the SAE 30 engine oil would be ok and is a near match to the 80/90 wt gear oil.

How do you disassemble this piece? (the half-shaft cage assembly)....is it just a case of undo the ring of six bolts inside the rear frame and withdraw the assembly together with the gear inside straight from the final drive?

What do those dowels line up?

The drum flange has to be removed first then the assembly comes out as you describe.
Dowels are used to anchor the bearing races so they don't get loose in their bores.

When you get in there and before you tear into it do a run-out check of brake drum (surface) wear. Also a pry bar check for movement should indicate if there are bigger problems.
