HI Guys,

 

It seems I am getting the bearing clicking noise again, however everything has been revised. 

 

Brand new Genuine Honda alternator fitted Dec 2014

New short Genuine Honda belt and revised routing Dec 2014.

 

New alternator has done approx 100k miles since fitted in 2014.

 

Or could it be just the mileage I have covered? Surely the bearings would have lasted longer?

 

Might go for remanufactured alternator this time

 

Just wondering if anyone has had the alternator bearings go bad again after replacing the alternator and shorter belt routing?

I thought the revised belt should not make this problem occur again? I'm sure it should last longer than that, the anti friction bearing should have life expectancy upto 40,000 hours but stop start can effect the life span.

Yeah I thought so too, unless it is something else. The clicky type sound is pretty much the same when the alternator was going way back in 2014. 

It disappears during the week and seems all ok but when the car is not sued over the weekend, Monday morning you can hear it slightly and then it disappears on my long commute.

 

I do have alot of start stop on the m25 but nothing too heavy for the car I dont think.

 

 

I guess I will have to monitor it and perhaps remove the belt when I get some time to feel the idler bearing and alternator bearings to see if they feel rough or anything.

Can the one way clutch pulley get damage quite easily on these?

The clutch pulley is a common problem. It is a good idea to take the belt off and check the idler bearing.

Ahh I thought so. I will try get the belt off check and go from there.
Cheers

Managed to remove the belt using the crow bar method.

The tensioner is really tough to move. haha. Just about got it back on. haha.

 

It seems that the idler tensioner pulley has abit of play in it and has a quite worn bearing but really the cause of the clicking.

The power steering pulley feels smooth with no play.

Will look to replace the idler pulley as preventative maintenance. 

 

The alternator does feel smooth with no play too, with the belt back on and the engine running the clicking sound is definitely coming from the alternator.

Exact same clicking sound when it occurred back in 2014 and along with other YouTube videos of the same issue.

Pretty disappointing, as it goes to show that the stressed out alternator bearing issue still persists regardless of the short belt routing.

Most likely Honda never anticipated owners will keep their cars for this long, and the revised belt routing was a quick fix solution at the time.

Whilst I have now got the shorter belt in reserve, I've not as yet gone down that route.

Currently on 160k give or take 1k.

Hi, I have just fitted a refurb alternator after an original honda one developed an awful clicking grinding noise. I will see how long this refurb lasts, one thing I noticed is there is a hell of a tension on the alternator pulley even with the shorter belt. Will see how it goes, refurb cost 85 off fleabay with 12 months guarantee.

Sometimes alternator clicking can be down to a tired battery, which could tie in with it being worse on a Monday.

'Hell of a tension', not a good start. Are you certain you have a belt with the correct dimensions ?

I've always adjusted things under the bonnet (of other cars) so the squealing doesn't start when the lights are on (and air con if fitted ) at idle on a cold morning.

Anything more is a recipe for disaster.

Hi, it's definitely the correct belt, was fitted by Honda along with a new engine, I will double check.
I just found the tensioner pulley extremely hard to budge and the actual tension on the belt a lot. Obviously designed this way and it now runs great. It just made me wonder what the pressure on the alternator would do over time.
I shall see how this cheap eBay alternator fairs over the next year.
