ThosL Posted August 30, 2020 Share Posted August 30, 2020 I was just on the phone with a mechanically inclined friend; any thoughts on procedure on this? Power steering fails, belt looks loose not broken, but looks like this belt drives most other pumps. Is this a tensioner failure usually?

GeneralDisorder Posted August 30, 2020 Share Posted August 30, 2020 Power steering belt is tensioned by the alternator. GD Quote Link to comment Share on other sites More sharing options...
ThosL Posted August 30, 2020 Author Share Posted August 30, 2020 Ok, if the crankshaft pulley fell off wouldn't i have heard it? Looking at the crankshaft I am seeing a smooth surface like the pulley disappeared leaving the belts. Quote Link to comment Share on other sites More sharing options...

heartless Posted August 30, 2020 Share Posted August 30, 2020 (edited) ummm, yeah.. that don't look right looks like perhaps the rubber failed, the outer part came off, and the belt wore the remaining part smooth Edited August 30, 2020 by heartless Quote Link to comment Share on other sites More sharing options...
ThosL Posted August 30, 2020 Author Share Posted August 30, 2020 (edited) Harmonic balancer? Edited August 30, 2020 by ThosL Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 31, 2020 Share Posted August 31, 2020 Yes. Harmonic balance failed completely. Either a new one from Subaru or one of the many "lightweight" units will work. I personally prefer the Fluidampr, but they aren't cheap. Lightweight is not really ideal for these engines as the weight helps to prevent phantom misfire codes, etc. We always recommend the Fluidampr, and a lightweight flywheel if you want to rev quick and not have misfire codes or problems with harmonics destroying bearings.

ThosL Posted August 31, 2020 Author Share Posted August 31, 2020 Roughly how much on these, and recommend do it yourself or have my mechanic do it? Last time this was worked on was around two years ago where I had to go back to the mechanic when it came apart. Quote Link to comment Share on other sites More sharing options...
lmdew Posted August 31, 2020 Share Posted August 31, 2020 I can send you a good used one for $25. You can do it yourself. If you are going that far, when was the Timing Belt done last? Cam and Crank Seals leaking? You might want to do it all at once. 1 Quote Link to comment Share on other sites More sharing options...
ThosL Posted August 31, 2020 Author Share Posted August 31, 2020 (edited) I saw some for under a hundred; the labor is going to be the real cost. I need to get the car back on the road soon, have four different jobs, was doing census taking when the car broke down. The harmonic balancer will just bolt back in and the belts go over that? Also need bolts for the unit. Edited August 31, 2020 by ThosL Quote Link to comment Share on other sites More sharing options...
heartless Posted August 31, 2020 Share Posted August 31, 2020 the crank pulley is one bolt thru the center - the one that holds it in place on the end of the crank - and you should be able to reuse the bolt you have. there are no other bolts associated with it. yes, simply unbolt what is there (takes some effort & you will need to keep the engine from turning over, as the torque is high) and install the replacement.. re-torque, put accessory belts on & adjust those.. done Quote Link to comment Share on other sites More sharing options...
ThosL Posted August 31, 2020 Author Share Posted August 31, 2020 I decided to let a mechanic handle it; the towing company said they would be there in 1 1/2 hours, ended up being 3. Agero, AAA is much better. Quote Link to comment Share on other sites More sharing options...
Rampage Posted August 31, 2020 Share Posted August 31, 2020 In the video you posted he put oil on the crank shaft bolt. Not a good idea. If the key is not super tight in the groove of the harmonic balancer, the bolt will loosen over time. I've seen it happen. The bolt should have Red Loctite on it. You will see it on the bolt you take out. Use a spray cleaner like 2+2 and then air in the bolt hole on the crank to clean it out. Torque: SOHC 94 ft. lb. DOHC 130 ft. lb.

ThosL Posted August 31, 2020 Author Share Posted August 31, 2020 I'm still not sure what happened here and since I never worked on the HB or the crankshaft, it must have had something to do with either a defective unit or defective installation.

It does happen. 2 Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 1, 2020 Share Posted September 1, 2020 It's just normal failure due to age of the rubber. I would get a new one from Subaru - they are $200 and the repair should take less than 1 hour. GD Quote Link to comment Share on other sites More sharing options...

First I’ve heard about using locktite on the crank bolt! I always use a small bit of grease to ensure I’m getting all the torque on the bolt properly. Never had an issue. Will cross reference service manual. Cheers Bennie Quote Link to comment Share on other sites More sharing options...
ThosL Posted September 1, 2020 Author Share Posted September 1, 2020 The mechanic is going to put it together this am, so hopefully they do it right. Car has 277K miles. I hope I am not being presumptuous that they will get it right. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 1, 2020 Share Posted September 1, 2020 DO NOT use loctite on the crank bolt. They are installed dry. Torque to 150 Ft/lbs. GD 2 1 Quote Link to comment Share on other sites More sharing options...
ThosL Posted September 1, 2020 Author Share Posted September 1, 2020 Hopefully they did it right; $250 or so for the job, also a belt they ordered when I had it inside the car. Quick turn around, now I can work. 2 Quote Link to comment Share on other sites More sharing options...

Many could literally do that repair with eyes closed. You’d have to be really unlucky to have issues with it. On 9/1/2020 at 9:03 AM, GeneralDisorder said: DO NOT use loctite on the crank bolt.

Properly installed dry it’s never budging, just like they don’t from the factory. 1 Quote Link to comment Share on other sites More sharing options...
ThosL Posted March 9, 2021 Author Share Posted March 9, 2021 Hi--the Harmonic Balancer loosened and started coming off today. Lucky I wasn't on the road when this happened. Is this simply a matter of tightening? I just tighten the bolt as hard as I can? I could have the shop where this was done tow it back and make sure it gets fixed.....I will call them anyway.

lmdew Posted March 10, 2021 Share Posted March 10, 2021 You can lock up the flex plate - Auto Trans or Flywheel - Manual Trans and torque the bolt. The other option is to use a quality strap wrench on the balancer to keep the engine from turning. As GD said 150 ft lbs. I use to take them to 125 ft lbs.

1 Lucky Texan Posted March 10, 2021 Share Posted March 10, 2021 ThosL - 150 ft lbs is about twice/a little more than twice, that used on a wheel lug nut. It's a LOT. Quote Link to comment Share on other sites More sharing options...
ThosL Posted March 10, 2021 Author Share Posted March 10, 2021 Ok, thanks. I don't have the tools to torque this down right, just very basic ones, I don't have a large 3/8" driver for the nut, though the 7/8 driver seems to fit, what is the metric on that?
