GMC Repair: How to replace Oil pan on GMC w4500 4.7l inline 4 deasel., exhaust pipes, deasel

Question
How long does it take to replace the oil pan on a 1999 GMC W4500 4.7L Inline 4 diesel motor? Do I have any brackets or Motor mounts to remove?

Answer
It appears that you will have to flywheel cover, oil cooler guides, front drive shaft. Unhook the exhaust pipes and remove the front engine mount bolts. Does not look like you should have to remove the motor mounts, but as you probably know...will probably make things easier.

Personally I would remove anything in my way.
