It's not coming from that pully at the bottom is it can't remember the name but I thought I had seen reports of that making the same sort of noise when it started to deteriorate

I'm sure you already know but, you only need to replace the outer bearing part. The inner mounting bit just presses in. Like most suzuki bearings it's a standard size available from any good bearing shop.

does it sound anything like this? I've a similar experience. Replaced the water pump, belts and radiator since. It has to be something that is being driven by the belts or at least something under tension by the belts, as when I had my radiator off to replace the water pump, I started my engine from cold just to see if the noise still persisted, which it didn't. I still hear the noise to this day.

I fell into the dealer trap on those last time round, not again. I do however have a spare I can build up onc3 the new bearing lands, minimum of down time, planned maintenance, etc.

Flash. Mine was similar to the video but a lot less pronounced. For the cost of a new bearing mine is quiet again. Bit of a faff to swap with everything in place but all done in 20 minutes after drifting the old one apart and back together.

Ah, which bearing is that, the main pulley bearing? Any idea of the bearing markings (sizing), I wouldn't mind replacing mine, it's driving me nuts and probably costing me MPG :D I'm guessing that the pulley bolt is a nightmare to take off as well.

Thanks, Generally, if I need anything Jimny I try to get from Martin. Question for you though, when you removed the tensioner, did you find that the bearing felt rough or smooth at all? Because, when I removed my tensioner last time during a belt change, I didn't feel any roughness or play of the bearing itself, which is why I put it right back without doing anything. Just curious as to what you found yourself.

With the tensioner in my hand i can just and i mean only just feel a tiny tiny little bit of latteral movement between the inner and outer bearing races, but it is definitely there. In the new bearing it is solid to the touch.

Ah, thanks. Sounds like my one could be worth replacing then. Really didn't feel like a worn bearing, but it's not much cost to replace really. I'll give that a go.

OK,

Just for information, I did my tensioner bearing today.

I took a pic of the tensioner unit disassembled. Pressed the outer ring off first, then pressed the centre part out. The centre part holds back a metal ring (pictured), which isn't attached to the centre part. I used a bearing press to push off the outer ring, but for the centre part, I just put a big brass drift in a vice and smacked the centre out, holding the tensioner like I was cracking an egg as I did and it came out easily with a good few swift, stern smacks.

I also suspect that my power steering pump tensioner bearing is bad. However, my mechanic told me he can receive me only on Saturday (two days in advance) and then he's gone for a surgery, so I don't have the time to have the bearing delivered internationally from Martin.

So, can someone tell me which aftermarket bearing model / designation (like the ones from SKF, Koyo, Timken, NSK, etc.) is fully compatible? Is there some special attribute which I need to pay attention to (like some special lips, sealing, or something)?


Also, should any pulleys be replaced while replacing the driving belts? What about the water pump (when should it be replaced)?
