1980 Eagle Air Problem

[ttrstudios]

What exactly do you mean by "service everything"? We did an oil change and filters, fuel filters, air filter looked ok, checked rear end and trany. Added hub oil where needed and adjusted all brakes. Is there something on a bus that needs attention more than lets say an 18 wheeler? I run an oil field trucking company so I've done my share of working on them but this bus is TOTALY different. So if I am missing something other than greasing it please let me know. Thanks
Craig.

Sounds like you are on the right track.

Don't forget to lube all the zerks. There's around 100 of them.

Here's a guide, I made it for my use, It is more stringent than Eagle recommends in some areas. Feel free to adapt it to your records if you want.

You might also get oil analysis for the engine. Trans also if it's automatic.




              MILEAGE________________DATE__________________________

   2000 Miles____________Slack adjusters (manual)

Akroyaleagle I appreciate that guide. I will surely use that.

I know it's a bit off topic but I have a speed question. The speedometer shows a "red line" of 55 mph. So what is an acceptable speed for this bus with a 5 speed manual transmission? There is no tach on this bus so I'm not sure what the rpm's are.

[eagle19952]

March 1974, all states adopted the 55 mph national maximum speed limit. Concerns about fuel availability and costs faded, however, and Congress in 1987 allowed states to increase speed limits on rural interstates to 65 mph.

The National Highway System Designation Act of 1995 repealed the maximum speed limit, allowing states to set their own limits for the first time since 1974. Many states quickly moved to raise speed limits on both rural and urban interstates and limited access roads.

It will be a 3:36 or 3:73 rear gear and the 5 speed if original was a direct 1:1, 65 mph should be a good cruising speed   

[akroyaleagle]

Virtually all the 3.73 rear ends will do 78mph top speed with auto and 24.5 tires.

I would counsel 1950-2000 rpm and take what that gives you, about what Clifford said.

Well the bus made it home just fine. No problems at all. I stopped for fuel and bled the brakes down just to see if it would air back up and it did like it should. I guess I'll fix it when it happens again. Anyway, the conversion starts!
