Timing belt idler pulley 182 issue

[Ddeece]

Hi Im in the middle of replacing the timing belt on a 2005 182 and the lower idler pulley I have in the kit is different. It has a larger inner bearing hole and the bearing is narrower. The idler on the head has a spigot to centre that bearing. The one I removed has a hole suited to the bolt. Its an skf kit. Have I been given the wrong idler pulley or is there a version that uses a spigot for both idlers.

The one with the larger centre is the upper roller

Have you been given 2 large diameter rollers or have you got 1 of each? Because you should have 1 smaller and 1 larger lol

I got two with the larger centre but one is smooth and the other is ribbed

Aye smooth is the upper and ribbed is lower mate

@JamesBryan has the timing belt spec sheet iirc, might give you an idea of where all the bits go

The photo shows both of the ribbed ones. The left one is the one I took off and is marked renault. The right one is the skf part. 17mm inner hole instead of 10mm and slso wont sit out enough to be inline.
