Pertronix - Hall Effect Vs Lobe Sensor what is the difference?

[ckh]

I just bought a set up off ebay it says "GETTING 1 PERTRONIX IGNITOR 1762LS LOBE SENSOR FOR THE NISSAN GQ PATROL WITH TB42 ENGINE" LS for lob sensing but further inb the description it says "Rotating cobalt magnets trigger a Hall Effect integrated circuit . ...no points to burn, ...no moving parts to wear out" it doesnt say anything about having to grinf the distributor shaft down, saw a post on another site saying "1762 (so I'm assuming it's not lobe sensing) and says the instructions that cam with that say "distributor must be removed from the car and a flange on the distributor shaft has to be Machined to 0.624 of an Inch"

Have I bought a lob sensing one as I hear they are not as reliably as the Hall effect type?

Also bought the Flame-Thrower® 40,000 volt coil they recommend to go with the ignightor.. I've read to check the rivies are right as its a manufacturing oversight, but bottom line is have I bought the right one, and what is the difference between hall effect and lob sensing, as i said in the ebay description its says its both!!!!!

Got both the ignigtor and flame thrower coil for 160 delivered from the USA...

The hall effect set up usually has an insert that sits under the rotor button after removing the points. The lobe sensor set up usually still uses the points as a switch. I haven't seen a lobe sensing set up for years because although they only have minimal current passing through the points (and they wont burn out) you still get wear on the rubbing block and the points will still need to be adjusted occasionally. With the hall effect sensor - once it is set up there is no wear and it should never need adjustment. Hope this helps.

This is the exact one I bought on ebay, like i says in one section it says lobe sensing in another hall effect, says not grinding necessary and nevery needs replacing...

Sounds like it is the type where the magnets sit under the rotor button and the hall effect device fits where the points used to be.

Upload a photo of the Box, Parts you have and the instructions. I got the Ignitor 2 and Flamethrower 2 which is a Hall Effect setup and I had my Fitter and Turner mate turn the shaft down for me, some people use a grinder, could use a a file and a drill press if you where careful enough.

Also you don't have to take the Dissy out of the car, you can pull it apart while in the bay and still mounted but you have to be aware of which way the rotor button was facing.

To disassemble the Dissy you take off the dissy cap leaving leads on it and cable tie out of the way, then mark which direction the rotor button is pointing on the housing of the dissy, remove rotor button and dust cap, you will see the points and condenser that sits on the side of the dissy, remove all the screws to pull out points and condenser (all screws except 2 that hold down the breaker plate) for the Lobe Sensing type, for the Hall Effect type you need to remove the dissy shaft, to remove the shaft you need to take out the extra two screws holding down the breaker plate and remove the circlip on the vacuum advance (be careful it doesn't go missing), remove the vacuum advance and the screw that's down the centre of the dissy shaft, lift out the breaker plate and you will see the two springs with the govenor weights on them, the shaft just slots in on two little studs and should slide out, take out the shaft machine it down and replace in opposite order repacking with high temp grease, on the position the points used to sit roughly you will put the ignitor and on the shaft you will put the magnet ring on first with the hexagonal internal diameter facing up, then the white spacing ring on top, should all just sit below the top of the rotor button.

Hope this helps

WOW !!! The one I had years ago (it was a Bosch brand) just fitted in without doing anything to the shaft. It was a different engine though. Sounds like a lot of work.

[Irvs]

Sounds like it but it really isn't, if you have the tools to grind it down the whole job should take an hour including the wiring

X2....... Follow Irvs's instructions posted above... They're pretty much spot on & once you've had a good look you'll get a good idea of whats bean said & be able to follow them easily.

Looking at the picture in the ebay add, there is a magnet which goes over the distrubutor shaft, and in the descriptin it says no wear on parts...
