Re: [diesel_mercedes] Final Drive Ratio

 

The trick is finding an appropriate ratio.  I swapped the center section from a 1985 300D into a 1983 300SD.  In this case the 85 was accident damaged and the 83 was noisy so the ratios didn't really matter. If you do change the center section, you might as well install rebuilt axles at the same time.  Good rebuilts are not that expensive and its a whole lot easier than changing the boots.

Do you mean to replace with a Mercedes rear end? Also I thought "set up" of these things had to be precise, like with dial indicators, or you could get into trouble. Just wondering. My 240's are very low geared. Max

It depends on the typ of rear drive .

In Mercedes it's very simple , just replace the final drive unit with one from a Junk Yard having the ratio you desire .

In the case of my elderly LBC's (BMC products, all)  , the rear axle has a removable center section often called a ' pumpkin ' or ' chunk ' ~ in both cases these items are usually never scavenged from junkers before final crushing so there's almost always plenty to choose from .

A good bit of labor involved but no real technical expertise necessary .

Re: [diesel_mercedes] Re: Power '82 240D Automatic

 

Well both my 240's, one auto and one manual are incredibly low geared. At controlled stops you do not need to brake. Winter just hit here. I park the diesels and roll out the Subie, I guess its time. I drove the 240 auto to town today and the temp barely got over the mark between 40 and 80. I'm not doing anything because soon its too cold to start and then we get snow and that what Subarus are for. Max

I think the 85 w123 had a slightly higher rear end.  At least that is what the owner said about his 300D Turbo.  Lawrence Rhodes
