Got a mechanical advance DUI HEI from MAF... What was supposed to be easy banana to install is turning out to be harder than I expected...
Read all the instructions (which is labled for a GM street/strip installation)... several times... before attempting this installation... even read how to change a distributor in my Haynes manual... couple of times, too...
Working on my 1976 FJ40 (11/95 mfg date); I have moved the heater hose out of way... removed and re-gapped (and cleaned) the spark plugs...
then I removed stock vacuum distributor with the points and rotor... marked where rotor was pointed...
Installed DUI and pointed its rotor to same place as old rotor was (np), but when I go to tighten the distributor hold down bracket, it doesn't seem to tighten down enough onto the DUI shaft to be able to keep it from freely rotating...
so I removed DUI and compared to stock shaft... DUI shaft is thinner than stock Toyota distributor
DUI installation documents also talk about a gasket being installed (none came with the DUI HEI kit), but there was none under the stock distributor... There was, however, an "O" ring on the shaft (which the DUI does not have this recess on the shaft for an "O" ring) of the stock distributor...
Also, included with the DUI was a metal piece (stamped B1), that appears to be "Y" shaped the width of the DUI shaft, and appears like a hold down bracket... but there is nothing about this piece in the (limited) documentation Anyone know what it's for?
Do I need to change out the hold down bracket for one that is slightly smaller (SAE vs Metric maybe)? Do I need to get a gasket, and if so, what gasket do I need?
Anyone installed one of these, and have any (friendly, please) better installation instructions and advice?
