3.07 to 2.47 gear swap 300sd 100/k
its now a week since the swap here are some of the differences.
--smoother shifts ...no more surges --drop of 700 rpm at 75 mph --cruising at 75 with engine purring at apprx 2600 --first tank at 34 mpg up from 29( note the 29 was with ugly motor noise entering cabin.) --no real big time loss in pick up only half a step slower, but still rocks at highway passing speeds. --discovered that i had wind noise at 75 for the first time. rock on diesel geek he did original swap robert bullard

geek swap
fun! i am not surprised at the mileage. if you can tolerate the liesurely take off the increase in mileage is a great thing. i cant think of any negatives in terms of wear, etc.

.............grrrrrr..............and to think that I garnered a 2.88 at a very good price to put in the SD. With all the kudos regarding the 2.47, I might have to start looking all over again. The 3.07 has certainly got to go.
BTW, can you answer a question regarding R&R of the diff? There is a mounting cap screw with a wide head on the aft side that secures the diff to the subframe. The cap screw appears to take a T-50 Torx bit. However, on the SDL, I immediately rounded the screw because it is made of some cheap material that cannot take any torque. Any advice on this fastener? How to remove it? Factory replacement?? |

yikes!
probably rusty, making id of the shape difficult. i am thinking if it rounded it right out that you may have guessed wrong as to what to insert into the business end to turn it. i have never removed a rear end myself (except on my '62 190b 30 years ago... that cured me.. although it was a tremendous amount of work, it worked out ok... and i believe that it was a higher gear, too). my shop charged me about $300 i believe, so it must have been a bout 4.5 hrs. of course they have alift and all the power tools.

torx
i think that they have to be very tight and almost have to be driven in with a hammer, so it is possible it wasnt in all the way either.
do you know where i can get a compression adapter for the 350?

adaptor
we have a fitting for the injector opening on a 123 bodied 240/300 injector. it looks like the kit you referenced me probably would do the trick but it looks like an entire set for all diesels ever made (almost). $130 isnt cheap but probably a fair price if one needed all that. i amhoping for an adaptor for the injector.

I have contemplated the situation, since I stripped it, and now am pondering whether that fastener is a 12 point metric socket head and not a Torx. I have purchased a good set of 12 point metric bits (Lisle) and may again attempt to remove this bolt this weekend. There may still be some material left, deeper into the fastener, whereby the 12 point bit would grip. It just seems that it stripped too easy. The tool could not have been correct. A proper tool should not have stripped it. In retrospect, I can't imagine M/B using a Torx in this application. |
