Bought a QDF42B differential to fit my 2.65 diff in my w201. Crown-wheel 1243530812 2.65 diff castnumber 1243434001 Wrong size/offset, and i realised i had bought the wrong diff. Contacted James at www.birdsauto.com and got both help, information and some blueprints with measurements to compare with. QDF42B is for a 3.07 or 3.27 ratio 185mm […]
EDIT: The QDF42B was not compatible with the 2.65 diff, but is for 3.07 and 3.27 gear ratio diffs. The QDF42B has a listed offset of 32.57mm, the QDF45B made for 2.87 diff has a offset of 28.69mm From quick measurement made the 2.65DIFF would have a measurement of about Todays delivery: QDF42B differential from […]
This example is on a 190e 2.6, swapping the original 3.27 diff for one from a 2.3 16v with LSD (also 3.27). For a list of possible gear-ratios, check here: http://mbturbo.com/gear-ratios/ Start by loosening the exhaust and the metal protector going around the cardanshaft right in front of the differential. They are going to […]
Removed the old differential, started with the four bolts on top, a w114 coupe has a lot better room than a regular w114 or w115, the tad longer trunk makes a huge difference in that way you dont have to fight against the back of the rear-seats with the two inner nuts/bolts. http://mbturbo.com/how-to-change-final-drive-w115/ the pictures […]
Bought a 3.07 to put in a friends car, with what i was told a low mileage, about 250000km (low mileage to be a 300tdt w123) dont know if the oil has been neglected, started the regular cleanup, and was about to swap the sealrings/dichtrings: A0039978347 but i left it be, it will probably run […]
2.47LSD with large yoke/flange, swapped side of driveshafts, Left to right, and right to left. will probably have to rebuild the LSD-stuff, but will se how it behaves. 2.47 with the 722.6 should give me something along 1600rpm @100km/h and with the m275s insane torque, it wont be a problem with those low rpms. will […]
LSD differentials, where+how to find
Overhauling a differential, changing flange / yoke, thrust rings and special tools to dissemble the differential.
Changing the differential/rearend/finaldrive of a w123, specialtools and basic walkthrou.
Gear ratios for r107, w114/w115, w123, w126, w124, w201 and expanding.
When i searched the internet for instructions, i couldnt find any,so today i took some photos during my change, hopefully it will help some of you with your projects.
