Engine Timing Tool Kit — Mercedes-Benz M133/M270/M274, A/B/C/E-Class

Precision timing work demands precision tools. This kit is built for Mercedes-Benz M133, M270 and M274 four-cylinder engines and gives you accurate camshaft locking for a clean timing service.

Why you need it

Timing a cam without locking tools is guesswork, and a tooth out can cost an engine. Locking bars and pins hold the camshafts at the right position while you work.

• M133, M270 and M274 engines
