Putting an 1100 motor back together

Post by cornfused »



I just got an 83 1100 in pieces I want to put the heads back I can line up the timing mark on the engine but without the heads on how do I get TDC? And then should I loosen all the valve tappets before installing the heads because I don't know when position the valves are in bear with me I'm new to this thanks

Just turn the crank so the crankshaft is mid-way between T1, and T2 mark in the inspection port, all the pistons should be in mid-stroke, then you can put the heads back on and turn the cams as much as you want. Valves won't touch any pistons. No need to loosen valves.

Once the heads are on and the cam timing marks are lined up, then turn the crankshaft to the T1 mark and put your cam belts on.

I'm guessing you mean the cam won't stay aligned? That is normal from the valve springs turning the cam. Several ways to overcome that.
1. Rotate the cam as you install the belt.
2. Turn the crank slightly to match the cam so that when turned both marks line up.
3. Clamp the cam sprocket to keep it from moving. Vise grips to the rescue. (be careful)
4. Use 3D printed cam blocks to hold the sprockets. (search here for the guy that sells these)
5. Wave magic wand.

Regardless how you do it. Rotate the engine by hand at least two full revolutions and ensure the timing marks all line up before putting it all back together.
