Diesel injector puller

[beeza]

I want to remove the injectors from my OM642 engine. What is the best puller for the job? The slide hammer type or the screw over collar type?

don't know which one is better, but with screw type you'll easily damage the cyl head cover as you provide lotsa surface load there. You need always to use proper 'washers' under the puller body.

On the other hand slider type sometimes may damage the injector itself, if injector is heavily stuck.

Are they stuck or is this a precaution?
