How 2: Replace Distributor Seals

[Glanza_Ragger]

Right, first off you need to order the 2 seals

part numbers :

Timing shaft seal : 90099 14088

Dizzy cap dust seal : 19127 74040

Before you start removing it, assuming youre timing is setup correct allready, mark on the dizzy housing and the head with either a marker or scratch a fine line so you know when you have it lined up to refit.

Unplug the kinglead, you can keep youre leads hooked up, because youre just going to move the dizzy cap out of the way.

Remove the 2x 8mm bolts securing the dizzy cap to the rotor housing, pull off and sit out of the way.

Also remove the large seal from around the dizzy cap. bin it.

Mark the rotor so you know which way is up..Or use the Denso logo thats stamped onto the rotor for a hint.

Remove the 2x Allen bolts which secure the timing housing to the head, try not to rotate the housing whilst its still secured in the cam..

Once the 2 allen bolts have been removed, hold the housing at each side of the housing where the allen bolts go in, wiggle the housing and pull out straight.

Dont turn the rotor shaft and if you lay it down, lay it down the way it will go back in so you can remember.dont rotate it though.

Remove the old o-ring [2] , cut it off with a sharp stanley knife as you are discarding it.

Get the new o-ring out and oil it up with some engine oil.

Roll it along the timing shaft untill it sits in the slot.

Make sure the end of the rotor arm [2] is in line with the 2 little marks on the end so you can line it up with the cam

Slide the timing shaft back in and add a bit more oil to the new o-ring before fully inserting it , with the housing lined up with the marks on the head.

Refit everything in reverse and fitting the new dust cover rubber into the dizzy cap, fire it up and keep an eye on it for a bit to check for leaks.

Job done!
