Ratcheting Chain Tensioner Mercedes W201 190E 2.5-16 M102 102.990

Chain tensioner with mounting materials for reliable operation of M102.990 16V engines found in 190E 2.5-16 models.

While most 2.5-16s were already equipped with a more reliable chain tensioner with ratcheting mechanism from the factory, there are still individual cases of defective chain tensioners or chain tensioners that work by means of oil pressure and therefore do not apply the correct pressure to the tensioning bar of the timing chain in every situation.

Chain guides, a new timing chain and other spare parts for 2.3 and 2.5 liter 16V engines, as well as other M102, M103 and M104 engines can also be found in our store.

Notes

We recommend that work on the timing system is always carried out by a specialist.
When installing, the plastic filler piece included must be shortened to the correct length or the old part must be reused.
