How do Points work on a tractor?
It’s the same on a tractor. The points just open and close on a cam inside the distributor to transmit an electric charge to the sparkplug(s). Just as the points begin to open the coil releases it’s charge to whatever sparkplug is in firing position. The distributor handles that.
How do you set the timing on a Massey Ferguson 35?
To set the timing chain, follow this procedure… To set the camshaft, first of all, set the tappet clearance on number 8 valve (the valve at the back of the engine closest to the steering wheel) to 0.023in (when the cam and rocker is in its lowest position). Then set number 7 valve to 0.025in.
How do I check my dwell points?
Measuring the dwell angle If you have just fitted new contact-breaker points, set them to approximately the right gap with a feeler gauge. With the dwell meter connected, start the engine and let it settle to a smooth tickover. If it will not tick over steadily, check the cause(s) and rectify any faults.
How do you set dwell on points?
Your dwell, and thus your points gap, needs to be set before you get out the timing light. To set the dwell, remove the distributor cap and rotor, ground the coil wire and remove all the spark plugs from the engine. Set up your dwell meter and hook up a remote starter.
What gap should points be set at?
The Haynes manual recommends a point gap of. 016-. 020 inches for engines used in the P1800.
How long do distributor points last?
They’re used constantly – every time your car is cranked and then the entire time the engine runs. This puts a lot of wear and tear on them (hence the reason better, more durable ignition systems have been created for newer cars). In general, you can expect your points and condenser to last around 15,000 miles or so.
Should points be open or closed at TDC?
Generally speaking, it is easiest to set the points when the piston is at TDC. Make sure the points are only open the thickness of the feeler gauge — aka, that the feeler gauge is not twisted and causing the points to be more open than they should — and then tighten the points screw back down.
What are points on a distributor?
Ignition points are a set of electrical contacts that switch the coil on and off at the proper time. The points are opened and closed by the mechanical action of the distributor shaft lobes pushing on them. The points have a tough job, switching up to eight amps of current many times per second at highway speed.
How do points and condensers work?
The condenser absorbs the energy and prevents arcing between the points each time they open. This condenser also aids in the rapid collapse of the magnetic field. At the same time, breaker points close to the complete the primary circuit, allowing primary current to flow.
