How big a deal is it to get the bearing changed?  My Series 60 is probably at the age where it needs to be done.  My best guess at miles on the bus (and engine) is between 400,000 and 500,000.  The odometer hadn't worked for a while when I got it and was at around 300,000.  The DDEC had been replaced or something because it showed like 50 miles.  400,000 seems probably pretty close based on the overall condition.

Something happened all right it was called Bobby Easter!

In a bus, the bull gear is fairly easy to get to since the engine is facing back towards the back door.
Series 60 has the valve gear train on the front of the engine. Most all new engines now have the valve gear train on the back of the engine-meaning any problems with the gears and out comes the engine. Good Luck, TomC

It just took me about 6 hrs to change the bull gear and the bearing on my 60 series in a DL you do need a good puller though

Wow 6 hours-you're a whirlwind worker. Most would probably take a couple days.

Mine is fairly easy just remove a few parts and pulleys and remove the front cover and you are there

I've seen more Cats with picture windows in the block than Detroits.  I personally towed in three of them that were owned by friends over the years.  A 1693, a 3406 and and 3408.  Lucky on the 1693 block, a fiberglass patch fixed the hole.
