1990 Honda Civic Distributor Rotor Shaft Spacer

Hi Beev,

Honda distributor bearing is 0.5 mm larger in diameter and during remans, if standard bearings are used, the shaft diameter would ne machined down to enable installation of the bearing. That is the reason Honda does not have any list for the part because it is non existence in OEM parts.

That is the reason for the rotor fitting loosely onto the shaft. A round of aluminium can foil should solve the problem.

Thanks, KHLow2008. That did the trick (see photos.)

Cyl #1 TDC places rotor set screw facing front of vehicle with straight shot for removal/install. Any other position is blind or obstructed. Remove Cyl # plug and put a length of heavy gauge solid copper wire into tower so you can see when Cyl is at top of stroke from drivers seat (handy if you don't have an assistant or remote starter. You need a drop light to see TDC mark on crank pulley. The thickness of soft drink can measured .004" so installing a semicircular shim in rotor shaft opening across from set screw hole took up necessary slack. 0.5mm is 0.009" and more than semicircle circumference was too tight to slide on Rotor. A square of electrical tape in nut driver socket keeps that pesky set screw from dropping. Be sure to hook dust shield tongs into slots on bottom of Coil. The cap clamps bottom of shield. Install cap straight-on so you don't damage coil contact.

Thank you again! v/r Beev

Glad to know you have fixed the problem.

This is one distributor that I hate to overhaul. Most of the torx screws would break when removed as they are very small and slender and has loctite applied.
