Starter motor eeek noise
Well it seems winter is finally over. It's been too long. My jeep has not turned over for 6 months. Since october. No time, bad weather...
So today I took the charged up 6 volt battery over to the garage. Pumped through the gas and hey away she goes !
I put in an electronic ignition system today and it's perfect.
So what's wrong ? Well I stopped the engine to take off some tools that were on the fenders before they fell off and pressed the starter. Strange noise. The usual starter motor-like whirr and EEEK ! It stopped. Like seized.
I tried again and the same thing happened. Then again and she started fine. Drove around a bit. Put back in the garage. Turned her off.
Pressed the starter again and the same EEEEK sound.
So I turned it over without the contact on. The starter motor turns fine. I then turned it over without the contact on and then turned the key and EEEK. Starter motor stopped.
And then she started again.
Could this be a problem with the bushing seizing ? I haven't had this problem before. I will take the starter motor off tomorrow to look at. Should the bushing be greased ?
The starter motor is from Ron. About 10 years old now.
Cheers.

Vacuum gauge trick ? You'll have to enlighten me there. I do have a vacuum gauge.

Re: Starter motor eeek noise
OK I'll check the timing with a strobe this weekend. When she runs, she sounds good but maybe the electronic ignition is not quite set right. I haven't touched it since taking the points out.

Re: Starter motor eeek noise
I'm surprised that the timing would have such an effect on the starter motor. Reason ?

This vacuum gauge stuff is just another SA bait.Luc" wrote:I bet you have timed your engine with the vacuum gauge and have the ignition to far advanced.
The only way to win with a toxic person is not to play.
Diagnosis is in order & that always starts with eliminating the simple stuff.
There are bushes in the starter & starter motor housing aligning the armature in that housing with the bush in the bell housing.
I recollect another contributor to this thread advocating a US cent/penny as a replacement for the small core plug [very often missing] sealing the bell housing bush to eliminate contaminants from this bush & it drying out.
Start by checking these bushes are lubricated before all this current vacuum gauge, timing & pinion guessing stuff comes to the fore.
Timing being too advanced puts additional load on the starter.
Easily eliminated [diagnosed]....
1. turn the starter with the ignition off
2. turn the starter the with the ignition on.
Major difference in turning speed [less resistance when the ignition is off] indicates an advanced ignition timing issue.
No difference & you are on just another one of those wild goose chases.

Re: Starter motor eeek noise
Cheers this is pointing towards an advanced timing problem. So definately time to get a strobe gun to it.
I'll let you all know.

Re: Starter motor eeek noise
Static timing is just as good with this vehicle.
First set the point gap correctly with feeler gauges or a dwell meter.
Either method reading correctly, indicates the points are set to 0.020".
Get the timing set on mark in window, then with the ignition on move the distributor housing slightly either way till the points just crack....you'll hear this or can set up a test light across the points.

Re: Starter motor eeek noise
A timing light is the best method, but not all timing lights are created equal and can be difficult to effectively position to view the timing hole. The old Army Timing Lights are easier to use. I install the timing pointer from a Late CJ-3A thru CJ-5 on the WWII engines and file a notch on the Crankshaft Pulley. It is not noticeable and it will make your Jeep engine smile.

Re: Starter motor eeek noise
I have electronic ignition on so I can't open the points.There are none ! So a timing light is the only way to go I guess.
See what you mean about getting a lamp in there.

Re: Starter motor eeek noise
A friend is coming Monday with his timing light so I can get this checked. And a 12v battery as I'm on 6v.
How you manage to actually see the timing marks on the flywheel and get a lamp in there, I do not know. I guess it's all done with mirrors...
Anyway in the meantime I retarded the timing 2/3° yesterday to see what difference it would make and it is pretty perfect !
The EEK noise has totally gone.
Didn't have time to go for a run though.
The easiest, smoothest 6 volt start ever. Electronic ignition (John Wisley in England). Not even a cough or splutter.
So I hope Monday we'll be able to see where it is with the lamp.
Thanks for the tips.

Re: Starter motor eeek noise
I use a Surplus GI timing light which is shorter than modern ones. About the only time the vacuum gage is used is for setting idle air mixture.

Re: Starter motor eeek noise
I cannot bless enough Luc for that timing pointer tip.
Following his advice, I've cut such a pointer based on a drawing found on the CJ-2a forum. It makes the timing check and adjustment so easy !
