How do i set timing marks on a allis c tractor

One mark is on cam gear mark on head line it hole in gear
camshaft intake and exhaust valve rocking that. Tic then on the back of two cam gears have to ,match up turn and match two sets of marks then back to tic them crank gear
one is straight up replace belt I would change water pump and seals also? good luck

22R 4 cyl.Get # 1 piston to TDC(stick the harmonic balancer back on temporary)setting the mark to O on the timing tab,pull the balancer back off and slip the chain on the crank gear after finding the single dot on the chain.Set the mark on the cam gear at very top and put the chain mark on that mark on the cam gear.Stick the cam gear back on the cam and bolt it back on.Your set now.

There is a match mark on the crank shaft gear and another one on the cam shaft gear. Line these two up and your timing will be set.

There are two kinds of timing, cam timing, and ignition timing. You don't adjust cam timing, it is set when the timing chain is installed. The timing chain cover is supposed to have a pointer welded to it with marks that line up with a mark on the harmonic balancer. (depending on the year of you engine these marks veri in appearance. Ignition timing is set while the engine is running with a strobe light that is triggered by the number one spark plug. On this engine (if it's stock) around 8-10 degrees BTDC. The ignition timing advances with cetrifical weights inside the distributor as well as a vacuum diaphragm. If either of these fail you will have a performance issue with a lack of power, and acceleration. If you are concerned about the cam gear being worn out yes they do wear out. Chevy made the gear teeth on the cam gear out of nylon to make then quieter, the replacement gears are usually cast iron. If you are thinking about changing the timing gears, the crank gear has to be pulled off with a puller, a lot of guys don't bother since it doesn't wear like the cam gear.

Set the gap on the high spot on the lob,it should be set at around 50000 or twice the plug gap,this is just a rule of thumb,but changing the timing by turning the distributer will get the engine to max performance after this has been done.

if you mean the cam shaft gear .. then there is a punch mark on both gears .. line up the punch marks .. if you have an ignition timing problem . then make sure the flywheel hasnt sheared its key (happens if the motor is suddenly stopped like hittig something ..

Rod bolt torque is 150 INCH POUNDS - - NOTE: INCH POUNDS NOT FOOT POUNDS

Valve timing is generally performed by matching either a dot or dash mark on the cam gear with a dash or dot on the crankshaft gear. If your engine has a ball bearing, the mark would be located on the crankshaft counter-balance. It is important that the marks match, EXACTLY. One mark will be on the top of a tooth on the gear, the corresponding mark will be found on the bottom of a tooth on the other gear.

i think you will need new valves if pulley come loose.timing marks on end of cams a slot on each cam ,the flats have to be level with the head,i use a piece of flat old ally bar for this.

It should be dot to dot. All marks should be on the gears only. I hope this will help you. Don

IF YOUR TIMING BELT BROKE OFF BEFORE YOU CHANGED THE TIMING BELT DO YOU HAVE TO TAKE THE COVER OFF OF THE HEAD VALVE LOOK AT THE CAMS AND YOU WILL SEE THAT THE VALVES ARE BENT IF THE CAM IS NOT TOUCHING THE VALVES ARE BENT BEFORE YOU ALINE THE CAM GEARS YOU HAVE TO PUT THE CRANK SHAFT GEAR IT HAS A MARK AT THE BOTTOM OF THE OIL PEN MAKE SURE THAT WHEN YOU GET IT ALL SET UP RETURN THE GEAR TO THE MARK ON PULLY ALSO THE TIMING MARKS ON THE CAMS HAS TO MARKS ON THE COVER THE LEFT CAM GOES AT 12:00 THE RIGHT CAM MAKE SURE THE EXHAUST LINE LINES UP AT 12:00 OTHERWISE IT WONT START BECAUSE YOU DONT HAVE NO COMPRESSION I HOPE THIS IS HELPFUL FOR ANYBODY THAT NEEDS TO REPAIR THE ENGINE
