1. Problem:I had to get a pulley off of my Power Steering pump and I couldn't use a jawed Pulley puller as that would just bend the pulley. I didnt have one of those clever pulley pullers.
Solution: I used the jawed pulley puller in one turn increments, and banged on the Puller Bolt each time after a turn of the bolt with a light hammer. The pulley came off in 5 minutes.

2.Problem: I had to put a "hard to get to" 12mm nut back on the underside of my Fuel Pump for my 87 300D. I could barely touch the location with my finger let alone use wrench.
Solution: I got a piece of 20" piano wire and bent the last 1/2" around the edge of the nut to hold it and then used super glue and a vise to really get a good hold. With the 20" reach of the wire I could easily position the nut properly. Then using the matching Bolt from the other side of the fuel pump, I was able to snag the nut and thread it into place...

When adjusting the vacuum control valve on the back of the injection pump (the one that feeds vacuum to the modulator valve on the transmission), you need 0 inches of mercury at full throttle. Through searching, it seems that alot of people people move the entire sea of throttle linkages, causing the engine to rev. However, the lever that controls that valve can be disconnected, so that you can move the lever to the full throttle position for extended periods of time without getting a chunk of valve cover stuck in your forehead :eek: .

When reinstalling the engine...
 

When reinstalling the rebuilt/new engine.,nine times out of ten its easier to mount the transmission ahead of time to the engine and installing the whole engine/trans in one fell swoop vise putting the engine in with a hoist and trans in from underneath the car indepedently.
I swear the extra work in doing it in one fell swoop vice climbing under your car later to wrestle and align that greasy transmission with your pilot shaft or torque converter in a second step provides safety and prevents injury. Yes, even if you have a transmission jack, which never seems to help much.
In the end you always end up trying to muscle it into place underneath the car, bench pressing the trans into place.
One time while replacing the transmission on a car separately, and tired, I dropped it on my face.

88% of W123 Diesel performance problems...
 

88% of W123 Diesel performance problems have nothing to do with misadjusted valves, Bad EGR's, incorrectly adjusted ALDA's or even tired injectors or compression.
I have seen posts blaming Cold start performance, slow acceleration, terrible idle, low mpg blamed on misadjusted valves, Bad EGR's, incorrectly adjusted ALDA's or even tired injectors or compression or other engine factors..I found out the hard way--The culprit is invariably your worn Injection Pump..get a new one or good used one...

Use the 80/20 Rule?

80% of your time may be spent in understanding and diagnosing the problem, and 20% repairing, or removing and replacing.
