Soldering is only sure way for positive connection, retard corrosion and keep from doing same connections over.
Crimp only has intruded into plumbing technologies and that's not gone well either.
Marine connectors are tinned in preparation for soldering.

I'd still choose a mechanical locking over a liquid for something so critical.


@ BlueG: That'll explain why my 250 GD has a weird brackets coming off the engine.

I was told that the bracket off the dampener bracket in particular was made because loctite wasn't invented back then. You either taught me that or another mate of mine.

@ Autovice: ► Marine grade terminals are defiantly the best, especially the marine tinned versions. Anything tinned just makes life so much easier. So that's a great tip mate! Even though I'd terrible luck with tinned products before I will try this shop in the near future.

“ They are crimped only and not soldered.”

► Crimping is great too. Infact people are fine just crimping things together. I personally crimp and then solder because I tend to overthink things.

“Added heat shrink tubing where needed “

► Agreed. I even think that heatshrink should be a must for any electrician's list of things to buy. Infact I do think the electrician at ICON derelict cars and trucks triple heat-shrinks his wiring splices. But this is a bias; I havn't met him myself though, as I've only heard of this through one of Jonathan Ward's videos. I kind of want to meet the man myself one day.

“ dab of dielectric grease before connecting them together. This is to keep dust and water out.”

► I defiantly love dielectric grease. I think it's literally silicone grease and it's safe to use on rubbers and the like. I personally use marine liquid tape for sealed joints since I personally think it provides a better seal for heat-shrink tubing tobe added. Literally anything with terminals exposed to the elements I use dielectric grease on. Literally everything else. DG defiantly has made it's prescience in my engine bay.

JP.
I have not seen an engine to engine dampener. I do not see the logic.
Engine to carrier or engine to shock tower I get.
As the engine vibrates all together, how does dampening timing cover to head make any sense unless the dampener just absorbs any vibration but where is the energy dissipated?
I would have thought that bracket was for the periscope.

BlueG, the dampener is for the serpentine belt!

In lieu of, or as well as tensioner pulleys? Not a fan of serpentine belts.

Yeah but serpentine belts are MUCH less failure-prone than V-belts. The shock absorber smooths out the vibration in the spring that keeps tension on the tensioner pulley. It's nice that MB made it this way as it's easy to release the spring externally for service, and everything is exposed and accessible.

I have seen far more serpentine belt failures on OM602, OM603, OM606 in different G wagen groups than V-belt failures. Some members having problems getting a serpentine belt hold more than a couole of weeks. Ofcourse because of other bad parts such as bearings etc. But this doesn't happen to V-belts in my opinion.

Converting a heater box from 24V to 12V is simply a matter of buying a 12V Bosch motor and a resistor. The Bosch motor without fan blade is 35 EUR. A far better resistor than what MB uses costs 10 EUR. For three speed you need two.
