sometimes my starter makes the grinding noise like when you try to start a car already running, does that mean its on its way out? are they easy to replace? any tips or info would be great

 

Assuming that you have a C2 (it's always a good idea to list the model & year btw) its sounds as though the starter solenoid is going out. Easy R&R however I suggest that you have it rebuilt rather than a replacement as you'll get a better job done. The replacements are a gamble. FYI, don't use it anymore until you've replaced/rebuilt it 'cause that grind is wearing away the flywheel teeth as well.

You don't say what car/engine but it could be a couple of things....besides the solenoid (item #6 in the first picture).

Sometimes the starter's internal drive is worn (item #2 in the first picture) or its spring is weak...or it could be the flywheel teeth have gotten worn and the starter now clashes when trying to engage (it doesn't take much). Both are easy to diagnose with a little disassembly but the second issue is tougher to fix.

 

I had a similar problem / noise and a few days ago the car wouldn't start at all. My problem was a small wire to the starter had vibrated loose and then completely disconnected. Clipped it back on, the car started and the grinding went away. You're a much more advanced mechanic than I am and probably have already checked that, but simple things first.

 

Remove the inspection cover, Probably have to remove the starter and oil filter too, and look at the teeth on the flywheel. If it is occasional, it is either the copper coated washer in the solenoid or the worn teeth on the flywheel caused by a weak bendix.
Hope it is the solenoid washer. Good Luck

 

thanks, I did put a new transmission in a few months ago

 

I'm talking "out of school" here but it seems to me in my dim past that the copper solenoid washer could be flipped over (just once) to provide a new contact surface...a 1/2 hour job IIRC...

 

Hi - my starter motor mounting bolt threads had stripped out (previous owner) and have knackered the flywheel teeth - can anyone point me in the direction of an online breakdown of parts needed to replace it please - or a description of how to do it and any other work worth doing at the same time? Thanks.

 

Well, first and foremost you'll need to repair the stripped threaded hole and consider possibly replacing the flywheel before you can even think of tackling the starter. This can turn out to be a pretty big job ie a transmission removal.

If that's the case and since you asked, you may as well do the clutch and pilot bushing replacement unless that was already addressed at the time of the transmission rebuild. Good luck.

Gary is right, but you can save the flywheel if you have a torch and welding gloves. Of course it has to be removed. Look at the teeth on the ring around the flywheel, it is press fit.
If the teeth are good on the clutch side (opposite the side the starter engages) heat the outer ring with a torch at least half way around the circumference. With the flywheel on a couple of blocks, the ring can be easily tapped off with a hammer and drift punch. Then quickly turn it over and tap it back on the flywheel. If it sticks, heat it again. There are U-tube videos on the internet on how to do it. You can also buy just the ring and save the expense of the flywheel if it is not heat cracked.

The old solenoids did have a removable clip under the copper washer on top of the spring that could be removed and allowed a one time flip of the washer. Also, you have to burnish the large contact as it will be pitted too. I have carefully dressed both with a file and saved the hassle of running to the parts store (We live in the woods). If you have an original number matching solenoid you want save, you can do this or swap out the parts from the new solenoid to rebuild your original.
Anyway, you must address the stripped holes in the block. The only easy way I know is Heli-coils, they have saved many a block and parts. you have to make sure the holes are not out of round or location, first. If so, it may require welding and a re-tap.

Sorry BUBBA got you.

If we knew where you are, there may be some old man that could help guide you on this. OPS, I see you are in California - can't help without a plane ticket.

Good Luck,
