Melonized steel distributor gears are nitrided for wear resistance. Nitriding is a form of case hardening. The item to be treated is heated in a metallurgical oven in an atmosphere of pure nitrogen to form a very hard glass like surface. In the process of heat treatment, areas to be free of nitriding can be painted with masking clay. Cheers
I use the Comp Cams composite gear on my billet steel camshaft in my big block Chevy engines. You can use a bronze gear on the billet cam but I don’t like the way my oil looks when I change my oil, it puts a minute amount of bronze in the oil and I suppose it doesn’t hurt anything but I want to be able to do a better inspection of my oil when I take it out of the pan.
The art of selling products is to the find the lowest cost part that does the job and make sure the part is not a Chinese ripoff that doesn’t meet the specification that it claims to have. The GM melonized gear is the only one I trust to meet the melonized specification and while it’s not cheap it’s not extravagantly priced.
@@moccasinmarine i agree, it’s hard to find parts that are not made in China. I’m 74 and been a drag racer since I was a teenager and I remember when GM parts started getting parts made in Mexico and I thought that was bad. 🤦♂️
Hi can you help me with a Volvo Gl 4.3 tbi fuel ,to set distribuir time? I saw you have a plug to put in The delco distributor , I think maybe is The reazon of The fuel excess Sorry I dont speak english obviusly
On fuel injected engines you install a jumper in the data link connector. You then set the timing to 8 degrees BTDC. This video shows how to set the timing. ua-cam.com/video/djjvdJAEdVY/v-deo.htmlsi=6gEJk6QIHUNXxebv
@@juanborchex2082 TBI or MPFI doesn’t matter. All you are doing is correlating the distributor position with where the ECM wants it when the datalink pins are jumpered. After the jumper is removed the ECM takes over the timing. The calibration in the ECM is different for a v6 vs. a V8.

What causes the dimpled bumpy surface on the round part of the gear? If a gear did not have this dimpled appearance could it still have been nitrided?

Excelent! And really thank you to answer me, Is The same in 4.3 G i with TBI 2003 ? I think my injection isn’t MPI
