TC-33DA Final Reduction Help

[wvrocks]

I'm attempting to check the fluid level in the final reduction units on my tractor. My owners manual on page 3-32 Figure 49 shows a big honkin bolt that is supposed to be the final reduction filler plug. Says the oil should be to the bottom of the hole when its full. Maybe I'm blind or maybe my tractor is special but that bolt/plug does not exist on my machine. I took the wheels off, I've looked at it from every possible angle, its not there, on either side.

So my question is, how do I check the fluid in the final reduction if the port isn't there to check it? I've checked the fluid at the dipstick on the axle and added just a bit to bring it up to full. Are the final reductions and the front diff all tied together?

Thanks, WVrocks

I can't tell you exactly on your Class II Boomer, but that bolt/plug is definitely there on my Class III. I can almost guarantee you that the final drive is not tied to the front axle. Did you look on the front and the rear side of the "dropbox"? I think the hex-head on the plug is about 3/4" if I remember correctly on my tractor.

There was a running change in the Class II front axle sometime mid 2005 that eliminated the level/fill plug on the bevel gear housing. Oil migrates between the center section and final drive swivel housings before and after the change. Now it is merely impossible to check or refill the finals directly as the older style housings allowed. This adds significantly to the time required for a drain & fill of the front axle. Your manual apparently predates your tractor as it has info on the prior axle housings.

TBN is such a great resource!

Thank you all, I was going crazy trying to find that nut. The way its shown in the diagram, Ray Charles should have been able to see it if it was there. Looking at my manual it says 11/03 on the cover. My machine was probably built in 05. Guesss my dealer just picked up the wrong manual or NH didn't change it.
