Am I correct I need to drain oil to replace oil line to DN50?

Floor hatch didn't help.  The floor hatch only allows access to the valve cover and that is about it. 

I managed to get my DN50 removed today.  Man is that sucker heavy!  The fitting was fairly easy to remove once I had access.  The threads on the fitting were damaged so the fitting needed replacement anyhow. 

Yes, it is turning out that I'm putting way too much time into a simple hose replacement.  My time is basically free since I can't make any more money by working more hours at my job.  I was just going to order the proper part from MCI/Dina today, but Catco doesn't seem to want to return the money for the hose they made wrong.  I just realized I drive by a hydraulic hose place every day 1 mile from home and I can get the 45 I need there.  With a new fitting I can use the hose from Catco.

great that it worked out.....but if they made the hose wrong it should be on them.  I wouldn't give them any more business if it was my $$

Yes, they should refund for a hose made wrong, but I don't have much leverage as a cash customer.  They don't have hardly anything for buses anyhow so no real reason to go back.  No engine parts for Detroit and no hoses or belts.  They mostly carry parts for trucks such as brakes, lights, truck mirrors, and air line parts for connecting truck and trailer.

It is all for the best as the 45 that I removed really needed to be replaced due to thread damage.  I can get a more standard connector now instead of the funky long cone one that was on there.
