Re: engine for a 4905 in central PA

I believe I have the same problem and will probably need to swap in a new engine in my 4905A. Any info on the engine in PA mentioned?

Also: what would you expect to pay for one?

[matzeinusa]

The one in MI was $1400 turbo without transmission.
Contact cheesie directly for the PA one.

Damn Matt,
Us none mechanics know to shut up and watch the wizzards try to help you. But know that we do watch with great fascination hoping to learn something. I was sure someone would pull a rabbit, or motor, out of their hat. I will have to be nicer to my 6V92 if motors are drying up. And now a moment of silence as another asphalt annihilator sadly goes off the active bus rolls.
Best of luck finding another bus.

Maybe I missed something, but is the bus otherwise in good shape? Or is it so bad that there is no point doing an in-frame to bring it back to life?

Matt have you tried these guys in West Sac. They had a 4106 that they rebuilt years ago and the guy never came back. Don't know if they still have it but I know they have 2 strokes or may know who does.

If they can't do an in-frame what is the differences between a LH and RH engine? I would think:

1. Cams
2. Starter
3. Blower

Could they not be transferred between the original and replacement engine?

[luvrbus]

Cams,oil pump;idler gear and starter if you have the right crank shaft the blowers are the same

Sounds almost exactly like my own situation (1978 P8M4905A).

 I assumed that opening all the draincocks would drain ALL the coolant. It did pop a freeze plug but now I'm seeping coolant into the oil, so either a crack or seals.   I had also overheated it, driving the long road up to Taos NM ,and had to change the top head gasket. Probably did some damage then, too.

One question: I read that these buses were designed so the engine could be changed out it a few hours. Is that right?

Whoever posted that it makes more sense to start over... I hate to admit it, but you're probably right. I only Paid $2500 for it 10+ years ago.

Anyone have use for a decent shell, CHEAP? Located in NY State. Previous owner worked for Grumman, assembling aircraft and did a beautiful job on the alterations he made to the skin- can't even tell they aren't original!

And I cringe to even mention it, but what is my approximate scrap value?
