Starter Motor Screetch Auto

[jims-terrano]

Just started today, like the pun:lol

Happened twice whilst it was jacked up sorting the oil leak out. Now it's happened this afternoon.

Forst turn of key starter screetchers so let go of key. Then try again and it's fine. Don't forget this is the automatic. Hope this truck is going to start behaving it's self.

Isn't this something to do with the ring gear engaging

It could be the same problem I have. if I wait till the light on the auto select switch go's out rather than the glow plug light before trying to start it, it never happens. ,,???

Jonela, can you explain that one please. Think I've missed something on the truck.

I think he's referring to the gearbox switch to the left of the steering wheel. Snow/sport switch. It lights up for a while when you turn on the ignition. Apparently if he leaves it to go off before starting, it doesn't slip on the ring gear.

Ahh right I understand now Ian. Cheers guys I'll take note of that. Forgive me for not going out in the monsoon we have tonight. I'll leave it until tomorrow morning.

To be honest cannot see how that can make any difference, it is a starter motor/ring gear problem short and sweet, Rick

 

[jims-terrano]

Starter motor worries me but ring gear freaks me out some what.

Just checking about how the starter works.

The motor starts to spin and the small gear on the starter moves along the shaft and engages with the ring gear?

Have I got that right. So hoping at the worst it is this mechanism that may be sticking but why it has been fine for all this time it should start today. Unless it is temperature related as it has got colder now hasn't it.

No nothing like, that was the old inertia type as fitted to Mini/1100, Ford Consul etc, yours has a solenoid on the top that also acts as a heavy duty relay, when energised it pulls a fulcrum which engages the pinion into the ring gear and at the end of the stroke pushes a plunger which presses a copper bar across the two heavy contacts powering the motor, what happens with age is the ring gear almost always stops in one of four places, so these four spots tend to wear so some times the contacts are made spinning the motor when the teeth have not engaged but meeting head on, often the cure is a new starter as the pinion teeth will have a good lead in edge which will be blunt on a motor that has spun but not engaged more then a few times, it is also possible to rotate the drive plate by a 6th so presenting new teeth at the normal stop positions but for this the box has to at least be moved back if not dropped, or easier engine out as the front diff does not need to be dropped on an Auto, Rick

Bizarre for sure. The switch position makes absolutely no difference to starting the engine. But it works for him somehow so long may it continue [emoji55]
certainly easier than removing a starter and possible ring gear.....

This is sounding rather costly and a big job. Suppose for now all I can do is see how it goes.

A replacement starter has to be first step doesn't it. Keep an eye out for a second hand one.

I have some starter pinions here so if you are able to remove your starter and strip it, not hard except the solenoid Philips screws can be very tight all the force you can muster to keep the driver in the head and a ratchet is good, but and there is always a but there are two types one with a nacelle and one without so if you post a pic I can sort the right pinion, if you are unsure look at my fairly recent thread think it was "broke down today", Rick

 

[jims-terrano]

Cheers Rick, as it's not a daily ride I'm going to see how it goes for now. It's only started happening today so will see if it gets any worse. It'll have recovery cover so even if worst happens the truck gets transported back home. Fingers crossed it'll last until the warmer weather comes.

I've started the car 4 times today and waited for the red light to go out, not had a problem with it so who knows may be there is something to it:thumb2

Wife went out in the car and it made the noise once but she didn't really understand about the red light or where it was :doh

I'll keep an eye on it this week.

 

[solarman216]

Believe me there is absolutely no connection whatsoever between the gear lever light and the starter not engaging, it is purely random on where the engine stops re ring gear and where the starter pinion is when it tries to engage, Rick

 

[jims-terrano]

Ok Rick, I'll have to see how it goes over nexr few weeks as I can't do anything now until December.

Got rear shocks to fit on the wifes daily ride terrano too which I'm not looking forward to.

 

[solarman216]

one possible explanation re your test starts, is that you probably only ran it for a very short period, so when it stopped it will most likely of not stopped in one of the normal 4 places due to being cold with thicker oil, just a thought, Rick

 

[jonela]

I think it is some sort of voltage problem cased by a relay somewhere or a connection, however i haven't got the time or the patients to fined it,so the light on the auto switch is just a a good guide ,as it just needs longer before you turn the key than the time it takes for the glow plug light to go out. Or maybe it is something to do with the auto select switch I don't know. :nenau But dont worry about the starter or the ring gear as I don't think they have any thing to do with it. mine has been doing it for two years and if it were serous I think I would know by now

I considered this after our conversation regarding mine but if it stopped in a place where the ring gear was worn and there for would not engage ,then you would have to move the flywheel by some means in order to bypas this .but when this happens it is just the initial turn of the key and if you wait longer on the second try it starts no problem,:nenau leading me to link it is definatley an electrical problem.
