300 5cyl. homemade prechamber puller
it has been stated that the prechamber threads are M22x1, which are the same as some Nissan half shafts and also some bicycle crank pullers/pushers.
Does anyone know what size and pitch the threads are inside the threaded ring, where the injector screws into? Does anyone have a cheap source for factory made tools? The cheapest I found is $40 to $50 for the puller and $80 to $90 for the ring tool. And, can anyone confirm that the OM621 engines from the 1960's use the same tools as the OM616 and OM617 from the 1970's and 1980's? Thanks. |
The eBay and Tool seller Zdmak has a the puller tool and the claim it works on 1967-1999 engines- 601, 602, 603, 604, 605, 606, 615, 616 & 617
I bought a used puller on eBay and was suprised to find that it needed a metric adapter in order for me to use it on my Slide Hammer. After checking I found that the internal threads on some of the tools are metric threads and some have american threads. If you end up buying besure to check so you get the one you want.
The Ring removal tool is being advertised as working on OM615, 616 & 617.
I found the Injector thread size buy looking up the Compression Tester Adapter (that goes into the Injector hole) and they give the thread size for that. It said 24mm x 2.
This forum has a tool rental section.
