crankshaft?

Still in the process of replacing things and curious about something. Should I be able to turn the crankshaft? My top two cam pulleys turn fine and the marks are almost aligned for correct timing but I am having an issue moving the cranks shaft any at all. I have removed the crankshaft pulley and replaced the timing gear but cannot get the crankshaft to turn any. Is this normal? If not, how can this be solved? What does it entail and how long would it take to fix?

Just changed out the water pump, old one was all corroded and rusted out, it seems radiator fluid sitting on the propeller for 26 years got to it. Also the other issue I am having is replacing the timing belt. I have loosed the tensioner and still cannot get the belt on. Any advice?

Did you remove the spark plugs? If you didnt ...do it. Hard to turn an engine with the plugs in.
Measure your new belt up to your old belt to make sure they are in the same ballpark.

Also check that the aux. shaft pulley is set in the correct position. The mark points to the bolt in the center of the tensioner spring. If it is out of position you may have the lobe contacting the rod assy. and locking up.

26 years is a long time for anything. many owners prefer to change their water pumps at every T-belt change (30k miles).

and, i have had two different people sell me the wrong belt over the years, once for a Ford, and once for a Fiat. kan't tell the difference until i attempt to install it. twice is enough for me to compare the old belt to the new belt every time now. saves some cursing and nicked knuckles.

yes I removed the spark plugs, and I also poured transmission fluid it and let it sit to re lubricate the components. The cam pulleys turn easily, the issue I am having is turning the crankshaft (has the timing gear and a pulley on the exterior. Should I be able to turn it. I have already tried turning it with a breaker bar and 38 mm socket, and it ended up stripping the bolt. How would I go about to see why it is froze up? I have to remove the oil pan and change the gasket anyways, will this give me access to the crankshaft, so i might be able to unfreeze it?

i've got the hayes repair manual and it doesnt seem to be all that great.

i bought the belt from Vicks autosports, so I am hoping they knew what they were doing and sent me the right one.

unless it had water in the oil pan, more than likely it's the piston rings that are frozen to the cyls, not the crankshaft.
Also, a 74 is an interference engine, if you've been turning the cams you probably have bent some valves

[NickSpider]

does that last statement apply to a 75 as well, considering that is the year of the car. How would you resolve this? Take the top off the engine?

removing the head would be the first step. If the cyls are rusty, plan on rebuilding that puppy
