Don't worry about the torque specs .. Most mechanics would put a socket/wrench on and get them 'really tight'

top bolt if it's a stud and bushing type gets tightened until the threads run out - usually where the bushings squash pretty good. the nut on top will stop turning. Other fasteners tighten to about 50 lbs or so depending on the size of the bolt or nut. small bolts like 5/16, 3/8, 10mm shaft size get about 30 lbs. Torque is all about the size of the bolt ( the diameter) . Large fasteners like 1/2 in. and above get 50 to 80 lbs. . hope this was helpful

You need a battery charger on this to do it. Put the key in and turn it on. Leave it on for ten minutes, turn it off for thirty seconds. Do this three times, then try to start the vehicle. If the battery goes low(below 5 volts) or you hit the starter. You have to start over. This is a relearn.

Without better information, I will assume you are saying the distributor gear has teeth missing or stripped. While replacing the gear is easy, you should first determine why it is damaged. You failed to mention what engine you are working on, but be aware that roller cam engines require a different distributor gear than non-roller types. In either case, bring the engine to TDC with cylinder #1 in firing position. This can be found by either putting a compression gauge in the # 1 spark plug hole, or have someone gently put a finger over the plug hole to feel when compression is pushing air out. Next, mark the position of the distributor body to the engine, and remove distributor and examine gear to find the roll pin which holds the gear in place. Set up some wooden block to hold the end of the gear without blocking the roll pin and using a punch smaller than the pin, hammer the roll pin out being careful to catch the pin on a cloth beneath your work. Obtain the correct replacement gear and install it on shaft using a small screwdriver to hold it in place. Check for excessive end play of distributor shaft and add shims if needed. Reinsert roll pin, then reinsert distributor, making sure that the rotor points to #1 plug connector on cap. The distributor will rotate some as it drops into place, so this may take more than one try. Note: if the distributor will not go all the way in, it may be necessary to use a flashlight and look down the hole where distributor goes to see the shaft the bottom of distributor must align with. You can use a long screwdriver to turn the oil pump drive shaft if needed. Install distributor hold down and tighten just enough to allow some resistance to turning distributor. Start engine and adjust timing. Final note. Reasons for distributor gear damage include: stuck oil pump; bad cam shaft gear area, bad bearings in distributor or other distributor problem; and even a very worn timing chain causing crazy vibration (rare).
