Serpentine belt pulley

>>2561109
uh, have you tried opening the hood and looking at the front of the engine for an obvious pulley missing?

>>2561122
it's redundant

>>2561128
>redundant pully
oh yeah forgot about those, there is at least a dozen redundant parts they just throw into the engine bay

>>2561140
Gods' willing..

it's an AC compressor pulley
you don't need it to run the motor, but you do need to bypass it with either a bypass pulley or a smaller belt
if it freed itself, your belt probably went flying off
guessing your AC compressor seized

>>2561292
Wrong. A/C compressor pulley would have a clutch on it.

>>2561394
I have had a truck refuse to start for me because the AC was seized so I know that this is not true for all vehicles.

>>2561109
It's either for power steering or the water pump. One will just make the rig a bitch to drive, the other it won't last long.

>>2561443
NTA however the clutch on the AC compressor can seize on.

>>2561109
If you need to ask about something this simple just take it to a shop

>>2561109
That's power steering all day

Idler pulley. The shaft goes through a bearing, the backside of it there with the splines obviously has some kind of retainer to keep it in the bearing, which has obviously fallen off or got stoled by gremlins to support drug habits.

You know, you could just lift the hood and look inside the engine and look (with your eyes please), and see which pulley is missing.

>he doesnt know the clutch can seize and lock in the operating position.

>>2561110
It's the base of your mom's butt plug
It has to be that big so that massive thing doesn't slip in all the way

>>2561537
Does the pulley in the pic have a clutch?

take your pick from any of the following:
idler

alternator
power steering

Power steering pulley.

Those generally just don't fall out. That poor engine.

>>2561482
Not an idler pully, too big, and idler pulleys have integrated bearings.
Learn to ID car parts better.

>>2561608

what pic? you didnt post a pic

>>2561651

Plenty of idler pullys aren't big. That pulley may have had an integrated bearing at one point, but clearly it's fallen apart, dummy.

>>2561109

If you had ever swapped a power steering pump that had this type of shaft you would not have posted all that nonsense. There is a special puller that grabs that hub on the pulley, and there is no place here for an "integrated bearing that fell apart".

God damn I hope you were trolling and not a complete idiot.

>>2561693

better view of that type hub

>>2561695

and the special tool that grabs it. once the two halves are around the hub (and a corresponding part on the puller, not shown), you slide that sleeve over the two halves and it werks.

>>2561693
and...?

What makes you think that type of pulley is used only on power steering pumps?

>>2561109
>>2561110
God forbid you open the hood and try to figure out what's missing.

>>2561140
Yeah, they're all related to emissions

>>2562598
every once in a while /diy/ will have a solid gold post like this, it makes the answering dumbass questions all day somehow feel worth it.

It's the framulator valve baffle. Unfortunately when they fall out like that it usually means the whole drive train needs to be replaced. It's about $18,000 when it's all said and done (you'll need a wheel alignment and fuel tank upgrade too).

The good news is that we can have it done by 5 PM tomorrow...will that be cash or credit card?

It's been 3 days and OP never came back after the first post. This was either a bullshit troll thread or the vehicle has already been repaired or drought to a shop for repairs. Stop trying to solve the problem and let the thread die.

>>2561109
Frank.

Looks like a power steering pump pulley. If your Power Steering system is tapped out, the pump can seize, and eventually the pump shaft snaps off.
