I recently was driving along on a beautiful sunny day when my 71 TR6 began to run very rough, I pulled over, popped the hood and started pulling plug wires while the car ran at idle. It appeared to be hitting on all 6 but still ran rough. I then pulled the distributor cap and and noticed both the cap as well as the rotor looked quite ragged. I made sure the rotor was fully seated and it was, but in doing so I noticed the distributor shaft had some side to side movement. I'm assuming my distributor is worn out but unsure. Can someone educate me on this before I order a new one.........Thank you for your time........Regards Gary

Gary --- Excess play in the bushings that house the rotor shaft can cause some fluctuation in the points opening (gap) but the wear here takes place over many thousands of miles. Fix this when time permits, but I suspect there's another reason for this sudden roughness in the engine.

The wear takes place over many thousands of miles, but at some point it reaches a point (or happens to wobble in such a way) as to cause a definite problem.

Many owners neglect to apply oil to the distributor (as required) which of course accelerates wear.

Shaft bushings are replaceable. If the shaft is also worn, longer or extra bushings can bare on an un-worn area of the shaft to return things to normal.

Electronic ignition can go a long way to negate timing scatter due to any inherent side movment in the distributor shaft.

I have sided to side motion on my rotor shaft also, now it caused my rotor contacts to be damaged and car running rough, does anyone know where to pick up rebuilt kits for the distributor, I have look on line at all the parts suppliers and can't find anything other then a rebuilt unit. I plan on pulling my engine this winter and rebuilding it and also want to rebuild the distributor. Thanks.

Excellent write up!

I too used the Bronze Oilite bushings, but a little longer than stock.

This is not a difficult job, and not requiring any special tools.

Would you replace the whole wheel hub for the sake of a bearing? No!
