Go to and type in your number or go to tools and rotary hammers and highlight your hammer, it will take you to another page and then you can look at a breakdown which is very specific on the direction and placement of the selector. The shift fork must be in the forward position and you can eyeball it with the post on the selector after you have it in position to lock it in. Remember you have to depress the plunger on the selector to reinstall it. Let me know if you still are having problems.

    HOW can you rate me as inappropriate when I gave you all the information you needed to complete this job. I tried to furnish you with the website and how to look at a schematic and this is how I am rated. Thank you

Bosch gbh5 will keep loosing its hammer

It sounds like the gearbox oil is getting low. The GBH5 uses oil in the gearbox, not a grease - the grease is used for assembly only. The correct type is a PG-150 (fully synthetic gear oil). Unable to find it in small quantities, I now use PAG150 oil for automotive a/c systems, it's available in small bottles. As for quantity, no-one seems to know... I just fill to cover the big bottom gears.

Remove the chrome drip ring, knock out the planetary pin and remove the planetary. Clean everything you have taken off with a rag or tissue, pop a small amount of grease on the teeth in the underside of the motor housing and reassemble. That's an easy fix that will last a reasonable time. The problem is the grease in the gearbox is getting old and breaking down. It is food grade grease so what leaks is harmless to you. Eventually you will need to replace the gearbox grease but that's an involved dirty job.

Yes, there is a trick to it. Make sure the pin is placed inside the little weird looking spring inside the hole. Press in the selector knob at about the five oclock position and rotate counter clockwise. Lemme know if you need further assistance. Please rate me
