| Engine mount stripped - no rplacement available
I have stripped the left engine mount on my 1981 G and part is no longer available - I have several choices
1. Weld up and retap
2. Drill and get heli coil fitted
3. Drill right through so that a bolt and nut can be used.
Has anyone tried option 3 ?

The best route is the helicoil, by far. Drilling through the top, and the subsequent machining of the top face required for a flat face to seat the nut or bolt head would significantly weaken the structure. Welding will also be chancy as far as inclusions, brittle/hard spots, what have you. With a helicoil, it'll be better than new. All things considered, it's probably the cheapest option too. Of course there's always option 4 to use yours as a pattern and have new fabbed from plate steel - then use the nut and bolt approach. -Dave G.

Another option similar to the heli-coil, but far superior, is a "Timed Insert". This is a more robust fix than the heli-coil and much less likely to back out or strip. The brand I used when I used to build Porsche enignes was Time-Sert. I assume they are still available. The procedure is
1. Drill out with supplied drill bit
2. Countersink with supplied countersink
3. Tap with supplied tap
4. Screw in the Time Sert
5. Set the Time Sert with the "roll thread tap" that comes with the kit. |

Bill,
I was thinking along the same lines with using a Keensert (fairchild fasteners). It sounds like they are very similar to the TimeSert.
Good luck to Peter with the repair regardless of approach.

Some more info - EPCNET states that it is no longer available ( Footnote 402) However my local dealer reports that the part is available ex Germany with 81 appended to the end of the part no - that is part no A615224170481. On the DC Classic website the part A6152241704 is listed as available from Classic centre ! Why does the EPC-NET report it as unavailable ! Price is a pretty hefty Euro 162.

The mystique of EPC / EPC-NET and DC deepens.... , How often the owner of website updates current database.
Word "available" means that somebody has this part in stock, ready for delivery to your front door.
Just to make sure how accurate the information on "Mercedes Benz Classic Center" web, punch the number:
A463-820-07-59
This is new HID Xenon headlight unit for 2007 G-Class, we received these parts at late December but they are still "unavailable"?

The Mercedes Benz classic website only lists parts that it deems to be for classic vehicles - I think it at least 20 years since last production. I also believe it lists parts that the Classic Centre itself has in stock . New parts for new vehicles are not listed. My local dealer says he can order the part - eventually had it repaired using a helicoil insert.
Cheers
