No car stuff yesterday. I needed a mental health day from cars… So this morning against my better judgement I figured I would replace the belt tensioner on the 300SEL. I wasn’t looking forward to this job, as I recalled it being a real PITA on the oldest son’s former 300E 2.6.
It was amazingly easy, almost scary in that regard, as I got it completely torn apart in under 30 minutes. So now I’ll go back out and clean parts and begin the reassembly. If anyone has any pointers/suggestions on properly tensioning the belt on an M103 I’m all ears. I’ve read what I can from the manuals and various forums, but none of it seems that clear cut. I’ve got a new tensioner and a pointer for it, as the old one had no pointer. The idler pulley on it was shot, that is, the bearing, as it made a “ticking” noise when you spun it. The belt that is on the engine is good, but I think I've got a new one. Gotta dig around in the new parts inventory to see if it’s there. I’ll need to clean all the pulleys on the engine and related components as the grooves are all filled with cruft from either crud or a failed previous belt that left remnants behind. This is good. I feel a lot better about this now that it came apart so easily. I’m going to check the fan clutch to make sure it’s full of fluid, too. If not I’ll add some. -D _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
