take it to a honda shop, or better yet trade it off for an ac of the orange persuasion.

Why are you asking about a HONDA car on an Allis-Chalmers tractor site. I would think there would be sites that are HONDA related that would be WAY more PRODUCTIVE. If you would have posted ALL of the details I would not have posted my first post. This is the way many post are, NOT ENOUGH DETAILS TO KNOW WHAT YOU ARE WORKING ON.

To the guys who replied to this post, You are misunderstanding this. He did not put a motor out of an allis chalmers D15 in his honda. He put a D15b vtec sohc motor in his honda which is not made by allis chalmers so there is no tractor motor in his car. He"s just asking for information about his honda in a tractor forum, which he might as well be talking to a brick wall.

More than an engine swap is involved. The engine control computer is the cause of your problems, This is a completely different engine and needs a computer chip for it. The computer speeds up the engine when; steering wheel is turn, air cond. is turned on, electrical load increases, etc. Check engine light is on for the same reason= different computer parameters. I don't know how you ended up here but a D15 is an Allis Chalmers tractor from WAY before the computer controlled age.

What you are saying seems incredible. Do you realize that the Honda engine you removed can rev up to 6000? The Allis engine cannot be safely operated above 2500 rpm.

Frankly, I don't believe this post.

Are you saying you put a TRACTOR ENGINE in a Honda Car? If you did, YES YOU DO REALY NEED HELP, and NOT of the mechanical kind.

Since we canít actually talk to our tractors, though some of the older sect of farmers might disagree, we use our five physical senses to observe and construe what our iron age friends are trying to tell us. We have already talked about some of the colors the unit might leave as clues to its well-being. Now we are going to use our noses to diagnose particular smells. ELECTRICAL SMELLS ... [Read Article]
