Oil Level in Steering Clutches

[Hartlyboy]

On my 450C I found the drain and fill plugs for the final drives and know you have to fill them to the level of the fill plug. Found the drain and fill plugs on the steering clutches but have not found any plug where you can check the level of the steering clutch cavity. The Service Manual doesn't cover that except that it says the transmission and steering clutches share a common sump. If that were the case, why would they specify the number of qts to go into each clutch? Maybe the overflow from the clutch cavity goes into the tranny sump?? Anyway, if any of you have run across this issue, can you tell me if it is possible to overfill the steering clutch cavities by filling through the hole above the tracks?

It seems that some (early model?) 450C's had the steering clutch housings and transmission separated by seals, and the oil level in the steering clutch housing had to be checked at the level plugs. Those types, according to my tech manual, could be easily converted to the common sump that was used on later models, and the seals etc. were no longer even available.
I'm not an authority, but you should be able to check your serial number in a late model parts catalog to see whether or not you have the common sump type, although, I suppose, you would not know if it had been converted or not unless you looked, or were the original owner.
If you DO have a 450C with the common sump the steering clutch housing oil level is checked with the transmission dipstick...
I hope this helps with your question.
