Need advice on installing an M10x1.5 Threaded insert in about 3/8 thick cast or milled - Looks cast and milled - aluminum Timing cover on the 2006 Jeep Liberty CRD.

The serpentine belt tensioner bolt stripped out. There is not a lot of room to get to it, but I think I CAN DRILL AND TAP with a right angle drill.

Are there any threaded inserts that would work better than others?

I will be ordering something in the morning or going to Fastenal if they have one.

Any advice would be appreciated.

Thanks

Sorry but I just saw your post. Just curious, how'd this work out?

Worked out fine so far. I used concrete anchor set epoxy on the threads when I installed the insert. I doubt it was necessary.

I have always preferred threaded inserts as opposed to heli-coils.

I bought from MSC.

I would not do it again. The part is only about $50. Mopar 05093935AA TENSIONER BRACKET

Our price: $43.93

https://www.google.com/search?q=0509393 ... 0&ie=UTF-8

I got a bad mind set right away. I was Googling the tensioner and problems, Found others with the same issue as me and they talked about using threaded inserts. I got that on my brain and never pushed checking for a replacement part.

The whole issue with mine was that to short of bolt was used to hold the tensioner and the aluminum did not have enough meat to hold it.

It had a M10-1.5x60 mm bolt and it calls for an M10-1.5 x 70 mm bolt. I would urge everybody to check their bolt length before they have this issue. a new bolt is about $2 compared to $50 for the fix. Checking is free.

I had an 80 mm bolt so I used that. Still had a little bit of thread left over. I was scared the bolt would bottom out to the shoulder before it tightened. But it worked.

I have been having problems finding the proper torque specs for related bolts and for the cross member under the transfer case.

I have personal issues with breaking things or under tightening things by hand. Over the years, I have lost my feel for hand tightening. Especially for anything under 1/2" in size.

Torque specs I think I have found:

Aluminum wheels - 100 ft. lbs.

Tensioner to tensioner mounting bracket - one bolt - M10x1.5x70mm - 34.6672 ft lbs or 47 Nm

Tensioner / power steering bracket to block bolts - 35 ft. lbs

In the books I saw it called the power steering bracket and the tensioner bracket depending on what part of the book I was looking at.


I have NOT found the torque specs for the 3 bolts from the power steering pump to the power steering pump / tensioner bracket

Nor have I found the torque specs for the 3 bolts for the power steering pump pulley.

I also have NOT found the torque specs for the 6 bolts on the transfer case cross member to frame. There are 3 bolts on either end of the cross member that hold it to the frame.

jrsavoie, If it is any consolation I have carried the repair over replace mindset way to far. Some one told me that a sensor on a gas tank was ridiculously expensive if you could find one so I tried repairing it 4 times using every fuel proof epoxy type putty/adhesive. The problem was the sensor wasn't accessible without dropping the tank about 4 inches. I found and bought a new sensor for about 20 bucks and never had that problem again. How bizarre the human brain is! :furious:

As a long time mechanic and a previous user of both repair options on many aluminum engine parts: in my humble opinion, a Heli-coil is a much stronger repair option than any threaded insert provided there is enough metal to support the Heli-Coil.
If someone can provide a different prospective, please do so..... :juggle:
We are all willing to learn new tricks.... :goink:

I've never hesitated using helis on non load bearing stuff, spark plugs, valve covers and such, when it comes to vibration intensive or irregular load items, top or bottom assessory brackets for power steering etc I'd rather drill tap and resize if possible the whole epoxy thing or the fill and drill and tap puttys always made me nervous but most of my hesitation is or was probably rooted in superstiton and hearsay, you know how that goes

Watched the shop boss stick a wire welder in a hole that had been half broke out till it filled up ground it flat drilled and taped it, never did get to look in it after he finished to see how uniform it was. All i could think was i wonder how much of the thread was bubble pitted but it's all about how much stress the area is going to be under, heck if nothing is going to be yanking on it and it's all in inch lbs gorilla glue or red loctite can hold things just with surface tension against a mostly stripped bolt, I've even seen people drill an eye through the shaft of a bolt and drive a nail through it and file it into a thread on a damaged large coarse thread bolt for a radiator mount or something on an ih tractor lol

How's everything holding up?

It's holding up well. Hasn't had much testing - not many hours or miles.

I have no fear for my fix. The idler pulley or tensioner will give up before an epoxied threaded insert will. Especially with a nut on the back side.

I would urge everybody to check the length of their bolt. According to the google search I was not the only one to have this problem. Though I never saw anybody else reference bolt length
