Removing delivery valves without special socket???
 

Hi i am trying to replace the delivery valve o rings on my 1985 190D, DOES ANYONE have any tips on how to accomplish this without the special socket required? i have in the past used the "keys" that hold the valve by tapping them gently with a flathead screwdriver a few times until it opens, but this time i am doing more damage than good and it doesnt seem to be loosening.
Any help is appreciated, am stranded. thanks

The last time how did you Torque them properly without the splined Socket?

The proper socket is around $25 from samstagsales.com

That is like trying to adjust a wrist watch with a pipe wrench.

This is a precision device, using the proper tool is not optional.

The torque requirements are rigorous and it is essential that they are followed precisely.

well i just wastes some money on this, it doesnt fit.
 

its actually a 33 tooth socket you need

Plus that blue point socket looks very fat and might not fit

$38, my bad

If you look at the bottom of the Ad there is a timing set with the Socket. I believe that Socket is for Cummins Bosch Pumps.
If it is a Cummins Socket you could at least sell it to someone.

Personally if you bought it from Snap-on I would complain and tell them there Ad is wrong; that it does not fit all Bosch Injectiom Pumps; and see what the do.

For those who don't like the Drip Method of timing take a look at the price of the Cummins timing set.

Any way you answered My question as I had wondered if that Socket and the Miller version would fit a Mercedes; it looks like not.

It might not be the length that is the issue.
I had bought some Laser Delivery Valve Sockets and they would not fit either. It turned out there was too much metal in the top and above the Splines of the Socket keeping it from sliding down over the Splines.

I complained and sent pictures to the Tool Company and ask them why thaey had not simply copied the Hazet Socket dimensions and they sent replacements for free.

I had to wait for about 2 months for them to get the Company in China to fix the dimensions; but they did.

By the way the redesigned Sockets are excellent and the Torque on the Delivery Vlave Holders so low that there is no Chinese Tool quality issues.

That is the price for the made in Japan KoKen socket. When they sold the Hazet Socket it was around $45; and then there is a shipping cost on top of that.

In the below pic is another part of the Delivery Valve Socket Issue.

I mentioned koken. Plus koken makes some great tools.

I mentioned the Koken name only to indicate that Samstag appears not to sell the Hazet Socket and switched to Koken. Not indicating there is any quality issues.

Due to the low Torque involved I actually think you could make a Delivery Valve Socket out of a good quality Aluminum Alloy or Brass and it would work fine.

The US bought or the Japanese sold a lot of cheap poor quality Tools back in the 1950s and early 1960s during the time when I was a Kid. In fact if something broke back then People would as if it was "Made in Japan".
But, as we know that has changed.

Japan switched to Electronic goods and after that the Tools sold here were good to excellent quality Tools.

They have the hazet socket, it's immediately above the koken and lists for $94.

make one by welding 2 of the retainers/shackle to an old socket. If you don't grind the tabs off, its more work turning it, but you can reuse them.

I just did this job on my 190d a couple months ago, super easy with the correct socket, just buy it. Its 33 tooth and fits perfectly. I bought the nice german version. :D
