Had a OM 352A 5 cylinder pump overhauled at Delco Diesel OKC.

They installed a revised torque plate IIRC and all new plungers...$1800.00 4 years ago.

I've seen grinders do it.


would an injection pump need that kinda accuracy? not really. getting down to a ten thousandth is easier than you may think...

I don't believe you have seen a grinder achieve .000001". And, if so.........I'd like the address of this grinder. The number is far less than the best possible surface finish that can be achieved with stone and there is no measuring equipment that is easily obtained to verify a size to .000001".

No, the injection pump does not need that accuracy. And getting down to .0001" (which is 100X your quoted figure) is difficult but not impossible.

I've been in this business for 20 years and the difficulties of achieving .0001" on bores is well known to me.

AAA gauge blocks are accurate to high tolerance (± 0.00005 mm or 0.000002 in) and used to establish standards.


my mistake, as these are lapped.



anyways; my point still stands. Bosch isn't some magical company. They use the same equipment found in many other shops.

Sounds like you guys are Really getting ripped to be charged 150 Per Element for a new one....

I have a Injection equipt supplier here in the UK that will supply Genuine Bosch elements for 25 pounds Sterling each, Thats around 50 bux...--Obviously, Not including fitting.

Easy enough to fit yourself anyway, BUT the pump will Have to be set up correctly afterwards, but you'll save yourself money by doing all the strip/rebuild work yourself--Only 'bench' time to pay for

All you need is the Element number, Its marked on the control-flank of the plunger--You may need a magnifying glass if your eyes are getting tired like mine....

As for bigger elements, If you can get/find a number, of an element that has the same characteristics apart from fuel volume/diameter then I'll see what I can do--Don't forget--The element can also control the advance in relation to speed/load due to the cut at the upper face as well as the helix cut, and this will have a bearing on torque and smoke etc at low engine speeds....
