This is probably a stupid question but on my 743 it looks like there is PVC pipe sleeves around the axles of each of the wheels. Any ideas what they were placed there for? It was like that when I purchased it.

You are referring to the small section of the axle that shows out the end between the seal and wheel hub? The previous owner may have put them there to help with leaks? or maybe to try and keep dirt out of the seals. Either way, this is not a factory setup mine just have the seal a bit of axle then the wheel hub.

Yes it is the small section of axle. If it is leaking I have not seen any evidence and have owned the machine around a year and a half. Hopefully they put them there for preventative maintenance to keep the seals clean.

If its not leaking don't touch them. I removed built up dirt once and the seal started leaking on me.....

Hello pondfisher; The pvc is there to keep TWINE and LONG WEEDS WIRE, etc. from tearing out the axle seals. Put them on mine After I dug out 6" of twine out of the seal. Hope this helps Bobmn

The fluid I am leaking around the axles, is this hydro fluid or is this from the chain case? Do I check the fluid level at the bubble eye on the side of the cab? I just don't want to mess up and run something dry.

Its chain case fluid, you check this by parking on level ground and removing the plug at the front of the chain case. Oil should just trickle out if the level is rite, Goodtech said Bobcat says if you can feel the oil through the hole the level is correct, so thats say 1/2” below the plug is acceptable.

Could you point me in the right direction to find the chain case cover? Do I raise the cab if so where do I look from there?

This question along with the last post. If I am low on chain case fluid how do you add it and what type of replacement fluid do you use?

Just use standard engine oil, 10W50 or so is fine
You don't need to lift the cab, but it does make it easier. Have a look down where the park brake is, remove the nut on the end of the brake lever to allow you to remove the pedal. Then un-do the 4 bolts holding the cover on and remove it. Add the oil in there and re-seal when done.
That easy!
Any problems just give me a yell.

Thanks I just had the chance to follow up on this tonight. Have been really busy at work this week. I will hopefully have the chance to check it out tomorrow evening as long as its not too cold. Tennessee is getting a blast of winter this week that we have been lucky to be without until now.
