Hi all,
I'm looking to buy a compression tester for my 84 and 87 300D's (OM617 & OM603). There are two different size adapters for the injector holes. According to Baum Tools:
Early MB = 24mm x 2.0mm
Late MB = 22mm x 1.5mm (not a common adapter, apparantly...)
I know the 24mm one will work with the OM617, but I'm not positive about the OM603. From what I can tell, the early OM603's (86/87) use the early adapter, and have the "pin" locknut for the prechambers. The later (90-up) 602, 603, and 606 engines use the "splined" locknut, and I'm guessing the 22mm adapter. Does anyone know for sure?
Also, the URL below had what looked like the best deals, at least the best I could find. Any comments on the vendor and/or tool manufacturer (Star-Hoffman)? Any better prices, mfr's, or vendors?

$95, ATD kit with 7 (?) adapters & case - ATD-5680
$34, ATD "by Hoffman" gauge only - ATD-5560
$12, ATD "by Hoffman" adapter only - ATD-5562
(The adapter is the 24mm, btw, separately or in the kit.)
Thanks! :-)
