Alternator with new regulator/brushes cuts out at 3500 RPM

My alternator stoped generating (but no charge light while running) so I replaced the regulator/brushes with the kit available here. Now, when I drive around with a volt meter attached to the battery, I see that the battery is being charged until the engine hits about 3700 RPM and doesn't resume charging until the RPM gets below 3400. The cut-in and cut-out RPM remain the same reguardless of what gear the car is in (even Park) or what accessories are on or off (although this does affect the battery voltage a little).

Front end shakes and rattles

I have a 1983, 300SD. At speeds around 60 to 70 mph I get vibration that fells like it is coming from the right front wheel and I also feel it thruogh the gas pedal. Also when making a right banking turn, (as in going from one freeway to another freeway), the front end will shake violently. This also feels like it is at the right front wheel. Can you give me any help as to what to look at and what to look for?

82 240D will not start when warm

I have an 82 240D with >217,000 mi. This summer it started not wanting to start once it reached operating temperature. It seems like it is getting air in the lines, but if you let it cool down then it will start again. I replaced the flex fuel line from the tank and the one under the hood on the suction side. I then bought why my diesel will not start, lots of info, nothing specific to hot starting problems. I have since put in a used tubo starter and a new timing chain. The engine turns over faster and has more pep but still refuses to start when warm.

Fuel Filter Replacemnent and other Difficulties- Be Prepared!

When my '82 300DT lost power on the freeway I managed to nurse it to my destination and got out my fuel spare filters. I installed a new prefilter and main filter, bypassed the FM10 water separator, pumped on the hand pump, and then found that the lack of a 17mm end wrench made bleeding the lines at the injectors real difficult as all I had was an adjustable wrench. Too bulky for that job. Then I screwed up by not reading Kent's instructions carefully and ran my battery down before the fuel lines were bled enough to get the engine going.
