W123 OM617 Injector pump swap

Follow
trythistv

What started as a misfire diagnostic quickly became an injector pump swap.
But at long last my car no longer misfires after a drive at highway speeds.
This is the longest video I've ever uploaded by a lot. Hope you enjoy and it makes sense!

This procedure is covered in 07_1200.pdf and 07_1201.pdf of the Factory service manual depending on if you use the timing locking tool or not.

Here are some of the special tools I used to do this:
➡ Timing tool: https://ebay.us/ITUzZp
Piezoelectric timing adapter: (Sealey TL95 and Gunson 77089 are the same):

➡ Innova 5568 Timing light: https://amzn.to/48BfVMj


Here are the more generic tools:
➡ 17mm Wrench: https://amzn.to/3SglObW
➡ 90 tooth 13mm (This would have been amazing with the finer tooth count): https://amzn.to/47vPOoF
➡ 13mm socket: https://amzn.to/3TYOOGx
➡ 3/8 Ratchet for socket (not a wobbly one): https://amzn.to/3vwqZf4
