Technical Starter Motor Noise After Car Has Started?

[s and b]

basically

mineral spirits
mineral oil
candle wax

great for some things. But this isn't a place I would use it ?

If you read my post i said i use duck oil,i run a garage i dont even use wd40 cant stand the stuff but the man in the street wont have duck oil in his shed.
No wonder people in the trade avoid forums when every word is picked over by the minority

If the clutch bearing is noisy it will screech with the pedal down.

I changed the clutch 3 months ago. It's not the bearing, it's the starter. I vaguely remember it doing it a couple of times last winter now.
Getting old so my memory isn't so good

If it is the starter you NEED to get it sorted or risk damage to flywheel etc.

it has only done it a handful of times when it is really really cold.
it will be ok until the better weather. i am sick of working on cars for the moment!

if it gets worse i will have to have a look at it.

Mine exactly the same, just once in a while when it is really cold overnight. I have only had the car a couple of weeks so will see how it goes for a while before tackling it. Likewise hopefully will wait until better weather...

What is it with the cold though, does it point to anything that is solvable without resorting to a new starter motor??

generally if the starter motor fails it will be


faulty solenoid
Do nothing single click or multi clicks but not crank

or dirt in the starter motors Bendix
normally causes it to not engage correctly
and can be cleaned outside with petrol and a paint brush let it dry and don't oil.
push the gear and make sure it moves up the spiral freely.

Worn bushes
usually results in slow cranking

The other failure mode is to stay engaged. This will give a screening noise


this is not a complete list but I have not come across a starter motor giving the symptoms of the original post.

until it starts failing regularly is going to be a guessing game.



from the description I would guess (around the 20 second mark) but I repeat this is a pure guess

Cold..

reduces battery output
So starter may not spin as well reducing the effectiveness of the engagement also.

Obviously any lubricant will de thicker.. stickier also..

Adding drag to all moving parts.

IF keeping clutch pedal depressed neutralises the squeak..

It could be a byproduct of..

Reduced drag..effectivelly upping battery output..

Or leading of the clutch releasebearing damping any worn bearing noises.

TBH.. I tend to crank with the clutch pedal depressed.. so this may mean my car is showing similar issues.. I am just masking it.

I don't think my screetch is clutch related as I too always start the car with the clutch depressed.

It did it again this morning (not particularly cold). Starts fine then a split second after releasing the ignition I hear a high pitched screetch lasting for less than a second. Bought as a used car from a local garage so might get them to have a look st the starter motor under 'warranty' but as it has not failed completely not sure I will get very far.

Ooh, think of all that axial load on the crankshaft with no oil pressure

does it sound similar to the noise in the video at around 20 seconds

Does the panda even have a spigot bearing? I can't recall seeing one and the gearbox input shaft doesn't have an unsplined section to suite a spigot bearing?

It isn't 100% TD5.

We are working blind trying to help.

its hard to describe a sound. Is it similar to the one in the video or not

The sound mine makes is not like that on the video. Much higher pitched for a split second... not sure about OP but their description sounded similar to what I am hearing.

Yummy...

There are two trains of thought on that. Cranking with pedal down = less strain on starter as gearbox is not turning. But as you've hinted the crank thrust bearings are dry until the oil pump catches up but then, so are the main bearings and big ends.

By the way dry engine bearings are completely silent until the big ends start to knock. Technically possible but they sound different and such disasters are almost unheard of these days.

Starter motors are a lot cheaper to replace than white metal bearings
I’ve never bought into this thing about less load on the starter. Gearbox input shafts aren’t hard to turn even with cold oil.

 

[dac69er]

the issue is happening more often now. every cold start makes that noise.
im 99.9% sure its simply the starter bendix not returning quickly or positively enough so it just catches on the flywheel ring gear when the engine starts.

looks like i am going to have to drop the starter off

will let you all know how i get on. hopefully i can just spray something on it for now rather than completely stripping it. can worry about doing a proper job in the summer!

That sounds like an aux belt squeak!?
