Anyone know how to find top dead center on a ford 2110 4 cylinder diesel. In manual it says to make sure cylinder 1&4 are top dead center any help be great thanks

If its easy to get the valve cover off roll it around till both rocker arms are loose will get you pretty dang close there should Aldo be a mark on the flywheel or injection pump that you can check to see if you have it dead on I'm not sure on your exact model . Put this on the ford forum as well .

Like vscummins has said, if you can remove the valve cover and roll it over by hand slowly, once both valves have closed AND then watch the timing mark on the flywheel. If that mark lines up right after both those valves have closed you are at TDC.

On a gas engine you can pull the number one spark plug and actually feel the compression stroke as air will be forced out the spark plug hole. I don't know if removing the injector on a diesel would get the same results or not. Might depend on how the prechamber is set up.

you didnt specify what you are doing. when #1 cyl. is at tdc... so is its running mate #4 cyl.
if you want #1 on tdc on compression for timing or valve setting its running mate #4 cyl. must have its valves on the rock, whick means one is closing and the other one opening at the same time as you roll the engine back and forth a bit. that guarantees you have #1 cyl. on compression stroke without removing an injector.when setting valves you watch the running mate of the cyl. you want to adjust.

Guys I have the oil pan off and am wanting to put a new balancer on can I look at the piston from the bottom and watch it until it gets to the top?

What kind of balancer? The harmonic balancer on the crankshaft would be keyed, and it wouldn't matter where the engine was.

From underneath you have no idea what the valves are doing. Yes the piston will be at TDC when it gets to the top, but is it on the compression stroke or the exhaust stroke?

Any balancer I have ever seen are keyed to the crankshaft. There is only one way for them to go on. I do not see why you would need to be on TDC for just changing the balancer.

Lanchester type counter balancers do need to be timed correctly as they run twice crankshaft speed in opposite directions. Most I've seen still had gear marks on the crank and balancer, at least IH, Continental, and Perkins did. Check the front pulley and flywheel, should be a TDC mark on one of them. Does not matter where the cam is, just 1 & 4 pistons at TDC.
