What is a camshaft rocker?
A rocker arm (in the context of an internal combustion engine of automotive, marine, motorcycle and reciprocating aviation types) is an oscillating lever that conveys radial movement from the cam lobe into linear movement at the poppet valve to open it.
Why is rocker arm made of I section?
The rocker arm is used to actuate the inlet and exhaust valves motion as directed by the cam and follower. It may be made of cast iron, cast steel, or malleable iron. In order to reduce inertia of the rocker arm, an I-section is used for the high speed engines and it may be rectangular section for low speed engines.
How do you replace a cam belt on a Mazda 323?
The normal method for manual cars is to remove the starter motor (which turns the engine over by contacting with the teeth on the flywheel) – you can then get access to the flywheel teeth. Alternatively you may well find that your car is equipped with a flywheel access hole underneath the engine/gearbox and you can use this to jam the teeth.
What are timing marks for Mazda 323 1.3 litre?
If anyone has any info on timing marks for the 1.3, 1.5 and 2 litre please use the contact link on this site to let me know so I can add it to this guide (it should be in the workshop manual).
What kind of car was the Mazda 323?
I used to own a Mazda 323F 1.8 BA shape (mid 1990’s) called ‘MOFF’ – you can see him in the picture opposite. Without a doubt the 323 F was one of the best cars I’ve ever owned (I’ve owned and restored quite a few cars) and even the wife liked him. So if you fancy some cheap thrills, go get one!
What do the pushrods do on a rocker arm?
The pushrods are associated with the camshaft. If the pushrods push up, the rocker arms push down. This downward pressure is directed toward the two valves in order to open or close them. The rocker arms must stay functional or else your intake valves and exhaust valves won’t open and close at the appropriate times.
What kind of camshafts do racing engines use?
Level 5 camshafts are designed for fully prepared, high compression, all-out racing engines and chassis.
