How to replace a distributor rotor and cap?
This will help you mark where the “pointed end” of the new rotor should be placed. Step 7: Remove the rotor screw and remove the rotor: On some distributors, the rotor will be secured to a small screw, typically in the middle of the rotor or along the edge. If your rotor has this screw, carefully remove the screw using a magnetized screw driver.
Which is the best description of screw machine rotors?
This paper presents a method of general geometrical definition of screw machine rotors and its manufacturing tools. It describes the details of lobe shape specification and focuses on a new lobe profile which yields a larger cross-sectional area and shorter sealing lines resulting in higher delivery rates for the same tip speed.
How are the rotors of a screw compressor made?
It consists of a pair of meshing rotors with helical grooves machined in them contained in a casing, which fits closely round them. The rotors and casing are separated by very small clearances. The rotors mesh like gears in such a manner that as they rotate the space formed between them and the casing is reduced progressively.
What should the contact forces between the rotors be?
Also, the contact forces between the rotors should be low in order to minimise internal friction losses. A typical screw rotor profile is shown in Fig. 2 with their sealing lines, as well as the clearance distribution, scaled 50 times between two rotor racks in the transverse cross section are presented far above.
Can a distributor cap fail at the same time?

What happens when you take the NEG battery cable off?
Taking the neg battery cable off is resetting SOMETHING that is causing the problem. PATS is going off. Taking the neg battery cable off is resetting SOMETHING that is causing the problem. Click to expand… Weak battery and poor connection at the terminals (dirty, corroded).
It’s very common for both the rotor and distributor cap to fail at the same time; especially if the rotor fails first. The engine idles rough: There are small electrodes on the bottom of the distributor cap called terminals.
What causes a car to start after disconnecting the battery?
Click to expand… Weak battery and poor connection at the terminals (dirty, corroded). That ‘click’ is very telling. Take the clamps off, clean the posts and the clamps with a wire brush, snadpaper or whatever and put it all back together. Speaking of corrosion, that sh!t is like cancer in the way it spreads.

How do you get a Phillips screw out of a brake rotor?
Grab one of those cheap phillips drill bits that are on the hardware store counters for like 35 cents, insert it into the phillips screw, and whack it with a hammer a few times. In my mind, this action shocks the screw and loosens the threads up a bit. I’m not sure if that’s true, but it seems to work for me.
