I tried the DIY service and repair manuals from
a website and it actually helped me repair transmission problem in my jcb 3cx site-master. it wont move forward or reverse, engine is good both solenoids for forward and reverse work.
I don't have much technical knowledge but I just followed it step-wise, and works perfect! got it from www.reliable-store.com

Prior to 1974 (HP @ RPM): 135 @ 2800 ------
After 1974, they increased the HP. (140HP @ 2800 rpm.)

Here are the spec's for the 1965 mercury comet, 289 V8:

For 1965, the Comet Cyclone was powered by the 289-cu.in. V-8 with 225hp, the same engine that was put into Mustangs. And for more power, there was a special high-performance package, better known as "Hi-Po," available with the Cyclone, and it shared the 271hp V-8 which, when installed in a Mustang, was known as the "K" code car. In the Comet, the engine code is "A." When equipped with the Hi-Po package, a 1965 Cyclone came standard with: 289 four-barrel high-performance engine, four-speed Toploader transmission, nine-inch differential, performance suspension, quick-ratio steering and 8,000-rpm Rotunda tachometer. However, the following items were extra-cost mandatory options with the 271hp engine package: four-speed transmission, heavy-duty front suspension, low-profile rayon tires and 42-amp alternator, according to 1965 sales information.

Its a 9-inch differential at best. Try this link for more data:

Remove any belts, pulleys, accessories that are in front of the front covers on the engine. Remove the covers, you should see the timing chain, crankshaft pulley and camshaft pulley. Turn the crankshaft be hand until the indicator mark on the crankshaft lines up with indicator mark on the engine. It will usually be a arrow or indicator line. Next look at the cam shaft pulley, it to will have an indicator mark, see that they are matched up, If not try turning the crankshaft one more revolution, align the marks and recheck the camshaft. If it is not possible to get both marks lined up at the same time the timing is off.

Do you know how check if every cilinder is working? with the engine in idle, go to the distribuitor cap and carefully unplug one at the time, every cilinder spark plug wire,in the cilinder you dont see a diference in rpm variation, that cilinder is not working, replace spark plug, if you see spark jumping fron the distribuitor cap torch the spark plug wire, another cause to a cilinder fail could be a loss of compression in one or more cilinder
