Today I finally got round to fit the bigger rear brakes. Which required some carefull modification to the back plates - of which I'm all but proud. Hence you'll never get to see it  But the main thing is: they'r on and there were no dramas. Except some MAD grinding noises - te back plates had warped and touched the discs. YUK! But I got that sorted. I hate rear brakes - always fiddly... Plan is to chnage for T-Modell wheel carriers with correct back plates (they don't fit the bigger discs) and bigger wheel bearings. I think that's a good idea. Since I have to continue rolling those 8x162 barrels... Anyway. They'r not that much bigger; 278 vs. 258mm and 42 vs. 38mm pistons. But the difference is notable! The stopping improved again - mucho awesome!!  And then I bedded in the discs - in a bit of an unconventional way  Yep - a diesel can do that as well! |

I'm starting to experience the negative effect of the brake upgrade... I got me some E-Class (210) 7,5x16" steels. And - they foul the caliper. On the inside.  The inner "mounting bell" of the R129 steels is much more narrow to allow clearance. I could run 10mm spacers - but this would affect the handling - so it's a nope.  Looks like I need to get me some alloys for winter use... |

could you shave the rear calipers a little bit? I doesn't look like there's a great deal of contact, so you'd only need to remove a small amount of metal.

The rears are not the problem - they'd fit even with 15" wheels. It's the front calipers... And no, I'm not going to take material off them. Other's can do bodge jobs like that. That's not for me. I rather buy wheels that fit.

 Always love reading updates on this tractor of yours. You're always so cheerful about it all. Just thought I'd point out after catching up, that it looks like the original hose wouldn't have rubbed if it was installed the other way around.  |

Yes - of course but there was no point as it was allready nearly rubbed through. I think MB messed this up when they put the replacement engine in the TDT... Speaking of replacement; I got replacements for the non-fiting 7.5x16" steels. In form of 8x16" ET34 manhole covers. I've been looking for a set for about a year, untill I finally got an offer for an acceptable price. They will need some corosion removed and some paint applied.   IMO the only acceptable alloys for a series 1 W124. I hate all those AMG and AMG-look-a-like alloys - of even worse, BBS or other "cross wire" wheels. Blaargh!  |

Soooo - long time no update. Simply because - there was nothing to report. But after the core plug replacement I still had a slight loss of coolant. It took me osme time to find the leak - and it meant a lot of work was ahead.  That'll be a head gasket leak. A small one. Very small. But I fugured I rather tackle the headgasket now than later... I would have made it through winter I guess - but why wait? Ease of mind etc. To get me going, I bought this arrangement of gaskets - for a surprising low amount of my moneys.  And then I started to strip the engine of it's ancillaries. Like manifold, turbo, injection lines, valve cover, some bits and bobs. And the worst part was yet to come; the bolts that hold the chain guides. They can be a royal bl00dy pain in the a$§ - not this time. Phew.     Next step - out with the camshaft and hydraulic lifters. Easy.  And then the head was allready loose - not backed together by the headgasket. Nice! And this meant - we had lift off!  The block looks to be in excellent condition - hone marks are still fully present! No surprise, the engine consumes less than half a liter of engine oil per 10.000km. Not unusual for those engines.  And then came the part I was most frightened off - turning the head around and inspect it closely. Those cylinder heads have a strong reputation of cracking. It's almost impossible to find uncracked heads. A professional repair is in the region of ~1000€ (welding, re-cut valv seats, re-cut prechamber bores etc.). A new head core is in the region of 2200€+. So I was not just a little scared of finding out about my head. And what can I say - NASTROVJA!!!!  It's completely free of any cracks.  MEGA-chuffed about that!!! Some cleaning and it can go back on straight away! But that's a job for tomorrow - I'm stil waiting for a lot of parts. One being the belt tensioner bearing - which was slightly worn  And I think I'm having the injector nozzls rebuild whilst they are out anyway... I don't have the pressure tester (resp. it's still being build), so I'll give that to someone else. That's it for today. My back hurts, so I'll clean the block & head tomorrow, parts are still in the post anyway and the nozzles are still here, waitng to be posted. Cheers, Jan |

Most of today was spent to carefully clean & degrease the head & block surfaces. I must have used like 3l of brake cleaner   Andthen I wanted to put the head back to where it belongs - when I came to the realisation that I could now lower the engine crane, direct the head and fiddle the timing chain through the head all at once... Quick call for help - which arrived shortlyx after. With unsuspected reinforments! And with 6 pairs f hands it was a walk in the park. Not. But all went well & quick - though Unsuspected Reinforcement kinked a fuel line in the process. Collateral damage.  And then came the exhausting part. 26 head bolts - 15nm, 35nm, 90° - 10 minute brake - 90°. That's torquing down 104 head bolts + 4 = 108 bolts wrestled. My arms hurt, my back hurts - I'm having a beer. And leave the rest for tomorrow...  Cheers! |

Yesterday I didn't do much - but almost killed myself. There's a hint in this picture. And I'm not going to talk about it.  Today was mostly spend with hunting down parts, which took the most of today. It seems fooking impossible to get that bl00dy ball bearing for the belt tensioner... I finaly took the last straw and ordered it at Mercedes' - for about twice the price. Sigh. At least they promised delivery tomorrow morning. Which meant - slow, lazy working - which means - I didn't get much done today. Put in the injectors with new VW (better) heat shields and torqued them down. And finaly got to install the new glow plugs I've been waiting for all week Now it's the best time to install them due to good access.  Connected the pre-glow wiring and put back the injection lines.  And then I came to the conclusion that there are two people I'd like to meet right now: A - the guy who constructed the inlet manifold B - the guy who invented the ball end hex key I'd give A a slap and then invite B for a night of drinking on my cost Without a ball end hex key you are basically: totaly screwed. Impossible to remove or install this... Even with such a genius tool it's a struggle. And back pain inducing.  But oh wel - I guess it's the price to pay for this engine I hope I've done everything right and the head gasket lasts a very long time - else I'll buy another car. And last but not least; this was in the post yesterday - thank you muchly, Mr rr69h!!  Yepp - steering wheel wrapped with dead cow Cheers, Jan |

Likewise. Though I've not yet installed it. Finaly belt tensioner:  Some other stuff, few bolts - driving.  And with this I'm probably going to end this thread since I've lost interest in this place here. I don't know - but it's chnaged a lot from what it was when I joined. Cheers, Jan |

It will be a shame if you decide to end the thread but I know it's quite a task maintaining a build thread. You are on my bookmarked threads list so I regularlay pop in to see what you've been up to, is there anywhere else I (We) might be able to follow the story?

As above, always look forward to your posts, plus your choice of car! It'd be a loss to the place without you.
that is all.

Did the cylinder head recieve any extra work whilst off, or just a clean up and refit? Nice to see one of these Merc coupes getting some tinkering, don't see many about here in Kent at all  I'm guessing the near death moment is the ratchet/torque wrench precariously close to the battery terminals |
