Oil pump chain question

[4bangerfury]

Old and new oil pump drive chains for an m10:



The new one is clearly wider than the old, but the part number on the box is the same as on realoem.

Is it safe to use the new one? The old one has some slack, but it's not terrible. I just don't want to pull this apart again to change an oil pump chain later.

As long as the chain can't rub on anything a slight amount of extra width won't hurt.

Looks a little bit beefier but time will tell

Looks like an M10 and an S14 oil pump chain to me.

And you shim them until tight, then remove one (thin) shim so there's just
a touch of 'flop' left...

This. That new incorrect chain will NOT work.

It has been discussed on the FAQ board. INA has been putting the wrong chains in the box (s14 instead of m10). This is already something that suppliers who are actually familiar with the m10 are well aware of and as a result are stocking/shipping the OEM chain which is still correct (it comes vacu-sealed against a piece of white cardboard).

Hope that helps.
