The bolt that has 6 names

Hey,

I own a 2003 Tundra, 4.0, 6 Cylinder, who just left the doctor's office with her squeaky belts replaced.

However, the mechanic said that a bolt has broken on (I'm not a car guy so bear with me here) "The alternator adjustment pulley". The truck is currently running because "We put a prybar under the alternator, and lifted it up, then tightened everything down - just like an 'oldskool' car". I was assured that there was no chance of excess wear or random explosions in my future if I continued to use the truck. However, I want it fixed right - and my mechanic says he is having a terrible time finding the bolt. So here I am.

I've attached a picture (or tried too - is there a post count required before you can post pictures?) of the offending piece.

If the picture doesn't post... it is an assembly made up of 2 bolts. The longer of the 2 bolts has a TORX head, and threads into the head of the smaller of the 2 bolts, so that they form a right angle. The head of the smaller bolt is knurled, and the threads of the smaller bolt meet with a flanged nut.

Scouring the internet I've seen similar pictures going by names of:

Alternator Adjustment Bolt
Idler Pulley Bolt
Tensioner Bolt
Alternator Tensioner Bolt
Belt Tensioner Pulley bolt
Drive Belt Tensioner Bolt

Can ya'll guide me to the right name for this thing? or Better yet where I can buy one? I'd LOVE an OEM replacement, even if it costs more than an aftermarket that does the same thing, but I'm open to all options...

 

Looks as if mechanic used zero penetrant on bolt. Small rust inside it is likely reason it broke. Seized up in the adjuster. Plier marks on left hand side of it by where the bolt head broke off is further evidence

I thought the 6cyl 4.0 was in the 2005-2006 models. Try searching for a truck with year model 2005 when searching for parts.

Perhaps @BubbaW or @empty_lord would be able to help you out using some google-fu.

 

Thanks, I will.

Shuold be a mild day around the office today, so this is my top priority.

 

Listen, this may be a really dumb question, but are you positive it's not the 3.4L?

Does it look like the below picture? (Picture A)


Or this picture below? (Picture B)

 

Same question, the 2003 brochure and various online parts speak of 3.4 V6 or 4.7 V8. Personally I’d take that broken bolt out, measure link of broke bolt, take it and rectangular bolt ?? to a hardware store. Should have no problem finding mm size bolt until you find OEM bolt if that’s desired !

 

This is PHM testing our knowledge. Lol

 

Bleh! You guys are probably right about the 3.4... here's my engine. I'm sorry for the confusion. Its definitely the V6.

I would measure and go to the hardware store, but after taking the picture he junked the parts.... I know this sounds really bad, but I've been going to this guy for over a decade and a half, and this is the first problem I've had.

 

Quit dropping deuces at Walmart and go snap a pic of your tensioner.

 

For whatever its worth, ya'll arent like the rifle forums. 3 posts in over there and there's already a troll, secondary topic going on, and a brawl that would be bloody if people could reach each other. lol

I appreciate it.

 

We usually wait for the second page to do that. Usually.....

 

I clean my SKS's in the dishwasher. You and I? We can be friends.

 

I'm telling ya! People don't understand that the "dish" part is misleading.

 

Would this be easier if I got a whole assembly of some sort?

I sorta stuck my head in the engine bay when I took that picture a few minutes ago, and didnt see this part in there but I probably wasnt looking in the right place...

I'm not afraid to spend money to fix my big grey baby. lol

That trucks sentimental value far outweighs its bluebook....

 

It wouldn't hurt. Tensioners do wear out over time.

 

Is that where the broken bolt would be? Its in that thing?

I'm currently scrolling pictures on google looking for an exploded view.

 

AH HA! DUDE! you are a champion! that picture is exactly what I needed!

 

You, and I can be friends!

Grey? This grey?

 

It's a shame your mechanic dude didn't use any wd-40 or other penetrant. That broken bolt could have probably been easily removed with some lube, and heat.

Patrick, ask the mechanic dude to dig through his shit can!

 

Sell your soul to the devil before hand

 

That tensioner you listed earlier doesn't look like it'll work.

Not sure if it's the same but the power steering one looks similar.

LOL

anybody who declares themselves the "Local a-hole" is somebody who I want on my side!

 

Thats on the list of things to do if I dont have success in finding it!

 

you might be on to something here... they sure do look similar...

 

Check this out... I think this is the exploded view with the tensioner in it. Looks like there are the right bolts!

I'm gonna get them and try!

Sorry! Got excited. LOL

 

Tell him to do it today before he empties it out! Don't want to risk it being totally gone forever if it isn't already.

 

I just sent him a message right that second - good idea.

 

Thats the one!
