We got a couple of nice days in a row so I stripped all the "in the way " stuff one day and pulled it the next.

As this bus is just outside the shop I dropped it onto pallets to move into shop later.

This is a interesting photo the size of the hole for the V730

Are you taking the 6V-71 out to put in a larger engine, or is this a replacement for your other 6V-71?  Might consider up grading to a 6V-92 since it is basically the same engine outside.  Just have to plumb up the turbo.  You would go from 210hp and 570lb/ft torque to 350hp and 1150lb/ft torque.  The 6V-71 will move your bus down the road-albeit at an leisurely rate.  If you stay in the midwest and east coast out of the mountains it will work.  But coming west of the Mississippi into the Rockies and Sierra Nevada's, it will be very slow going in the mountains.  I know I took a route during summer with 24 percent grades at times, and I know that if my engine wasn't turbo'ed (8V-71) I wouldn't have made it, and my engine is at 375hp and 1175lb/ft torque.  Without the turbo, I wouldn't have even tried that route.  Good Luck, TomC

Hi Tom  No such luck I am just swapping the engine with another 6V71.

I am just doing this to create work for myself :)  I needed to pull my engine out to do some bulkhead repairs and modifications to the bulkhead to  just install the V730.

My 6V71 is running good but along came a local transit bus that was involved in a accident that the insurance company wrote off.

I was talking to the transit manager and he advised me that the power train was rebuilt less 80,000 km earlier so I waited until the insurance company auctioned it off and I got the whole bus for $ 755.00

It had good rubber and a full tank of fuel so I got my $$ back with a little work.

I was planning to do what you suggested as I have a 8V71 with jakes ( running but tired ) in the shop but the local Detroit dealer needed  $ 18,000 canuck bucks to rebuild and do some of the mods you suggested.

So I am just going to make the swap while I am repairing the bulkhead for now.
