engine noise when cranking

[Brandon Jones 2]

when i crank my trac in the morning i get a sound as if the fan is hitting something but as soon as it idles down from cranking it goes away and it only does it when the engine is cold and has sat over night. o yea the new belt fixed my squeaking noies.

Could it be a dry engine (no oil) at start-up? Watch your oil pressure gauge to see if it takes a split second after start-up to go up.

as soon as i crank it it pops up to normal. and before anyone ask i do change my oil every 3000 miles.

but if that was the prob what should i do about it

Almost sounds like the bendix of the starter to me.

 

[Brandon Jones 2]

ok thats a new one on me please break that down for me

 

[Kevin Palmer]

Ok, looking at this picture, it is item number 2.



What happens is, the gear (teeth) them selves become defective, or, the clutch within the Bendix and or the sleeve it all slides on wears. When this happens, it affects how the engine turns over as it is a poor engagement.

Here is a good shot, though not set up like the Trac,,, it is a good representation...

thanks for the pics never tore a starter apart

I was thinking bendix not throwing the gear in enough. Then I saw coasties post...

Depending on the age and wear and tear. If it is the starter. May be better for a new or remanufactored. Other new parts will be installed.

If yours is a Job 1, sounds like the timing chain tensioners.

ive heard that i would need to take it somewhere to have that checked. is this true?

 

[EddieS'04]

I thought the tensenors caused chain rattle at 1500 to 2000 rpm...

 

[Dingo]

Not always, Eddie. Usually, it sounds like someone is shaking a beer can full of gravel on startup.

 

[Brandon Jones 2]

yes that would be bout the sound i'm getting only when cold start ups once its warm it never does it

I have the exact same problem. The hubby said it sounds like a dry engine, like the seals aren't able to hold oil up in the engine for that long of a time so the engine is dry in the morning.



Question...if it was a starter...wouldn't it do it all of the time and not just on cold starts?

good point kimbros my truck didnt do it when cranking this time when it has sat for over 12 hours.
