Noisy Starter
Hi Guys,
My Nissan has just started to make an occasional noise when I crank the starter. It sounds like the little gear which spins the fly wheel is slipping or not contacting properly.
It only happens probably once every 10 starts and the motor always starts straight away once I retry the ignition.
I am wondering if I can simply replace the starter gear and not the whole starter? Also how easy is it to get to the starter? Any advice or experience is welcome! If anyone has a cheap starter that will fit a 1998 GU 4.2 let know.
Lloyd

The starter motor is the easy part of this job, just get a reco starter from your local auto elec. But be warned, replacing the starter motor on its own won't fix the problem. The real problem is the wear spots on your flywheel ring gear. If it's only just started happening there may only be 1 wear spot, which is why it only plays up occasionally. As the starter gear continues to wear, you will end up with 3 wear spots-a 6 cyilnder engine will usually always stop in one of those 3 positions. Fixing the flywheel ring gear is a gearbox or engine out job, and that's a big job.
Sorry to be the bearer of bad news, but the starter and ring gear need to be done together.

I agree with Tony on all counts Im sorry to say, this is normally whats found in these circumstances.
However this could stay this way & not get to much worse for quite a while..
Cheers

Thanks Tony,
Just wondering what sort of mileage I will get out of the thing before I need to do this? Like I said it only happens probably 1 in 20 cranks of the starter, all the other time the things starts straight away. Is this a job I could attempt myself given the right tools and help? What is involved? And what sort of round-about cost would it be if I got a mechanic to do it for me?
Also are there anything I can do to prevent it from getting worse or slow the wear down?

The problem will get progressively worse, how long that takes is anyone's guess, but generally the more you use your car the quicker it will happen.
If you do get stuck where the starter just refuses to engage, put the vehicle in gear, handbrake off, and rock the car manually to turn the engine over just enough to get to an undamaged part of the ring gear. Your in trouble if this happens and your car is an auto.
Given the right tools and help, you could do this job at home. I wouldn't attempt to do it by yourself, the gearbox weighs about 200kg so have some one help you getting the box in and out. You will need a couple of big trolley jacks too.
If you have access to an engine lift crane, then pull the engine out, I reckon that would be an easier way to do it. Either way you will need to know how to line up a clutch. How long has it been since you replaced the clutch? Could be a good time to replace it.
Getting a mechanic to do the job would be mainly labour costs, probably at least 8 hours. Most places charge about $100 hour or more.

Thanks Tony,
I can get access to most of those things quiet easily. The clutch has actually just been done, its a shame the guys I bought it from didn't do this then as well! I have a few mates here who are good mechanics and happy to help out over a few beers on a weekend so that will probably be the way I go.
From what you've said I take it that it will gradually wear and as it does it will be harder and harder to get the starter to engage the flywheel? So at the moment it happens probably 1 in 20 cranks, as it wears this will become more frequent until eventually it wont engage at all is that right?
Why I am asking is that I was planning on going on a few short trips in it soon and I don't want to end up along way from home and have the thing unable to start on me, from what you have said it sounds like its not something that will happen suddenly. Might go down to the local mechanic and get some details anyway.

Tony,
Just another line of thought. I have been told that the starter gear is made of softer metal so that it should wear before the flywheel gear? Is this true? Would it be worth just replacing the starter gear? Can I check the flywheel for wear by just taking the starter of?

With mirrors and a torch you should be able to see the wear on the ring gear with the starter out. From my experience the ring gears wear just as fast as the starter pinion.
As for going bush before you fix it, just remember, Murphy is never far away!

Yeah I agree about bloody murphy mate!
I have just finished packing the truck for a weekend camping trip though! Although not too far from home and not really out bush so we will just see how she goes. Sounds like I might have to get prepared to do this big job! Oh well, good fun learning on the way, and thats what you get for buying a 4wd with alot of km's already on the clock.
Thanks again for the advice, I might need some helpful hints when I try and fix it up.

I'd offer to help you with the job myself, but Wee Waa's a long way from Brisbane.
