We are about to purchase a bus which has a rebuilt engine and it has not been run for a couple of months. I read a previous conversation about using your bus at least once a month because letting it sit could cause damage to the engine; the fact that this bus has not be started for a couple of months has raised a concern for us. Are there some tips for starting an engine which has not been started and run on a regular basis? |

Ken, don't let setting a couple of months throw you too much. While there has been a lot of advice as to the right way to lay up the engine, the damage that might occur in a couple of months should be very slight in the overall scheme of things.
Make sure your coolant level is safe and make sure the lube and steering oils are at safe levels. If the engine has adequate battery and fuel and it is not too cold, it should start right up.
If it doesn't under those conditions, its not likely that the reason is because it sat for a couple of months.
Long idling periods are not good for any engines and the Detroit two stroke should be ready to drive in a couple of minutes. Drive easy until you've got some temperature on the guage and then drive at the desired speed.
There is a difference between good practice and whether you'll be able to notice any poor performance. If it doesn't start up under good conditions, you might take a serious look at your seller.
Good luck!

I park a number of collectible cars for number of months each winter. I realize they aren't diesel powered, but I haven't had any problems as a result. If I happen to start them in the winter (which I have done some years), I always let them run until they have warmed up to normal operating temperature.
The big thing to check is any linkages which may have frozen or become stiff due to storage. You want to make sure that the thottle linkage andthe fuel shut down are both working. Detroit Dielsel tend to smke somewhat at first, but will vlear up as the engine warms up. Fast idle won't engage until ari pressure is up. If fast idle is selected, don't press on the accelerator pedal.- If you do the fast idle when it comes on will be too high. If you need to modulate or hold the accelerator part way down when the engine is first started, be sure and switch fast idle off.

When I picked up our 4106 last summer, it had just been thru an A service where they replaced all the injectors and adjusted the rack. Well it is a rebuilt 8V71 as well but didn't start or run worth a hoot. I was sweting bullets thinking the worst. I got another mechanic to go over it and he found the rack out of adjustment and now it runs great. |
