I cannot get the plunger/plug out of my TR7 oil pump. I've got everything else apart quite happily. The manual says very helpfully "use a suitable soft drift to tap out the plug from the underside of the pump cover" but I cannot get any kind of drift in there. I've tried WD40 and heat to loosen it up. Any thoughts. Thanks
Hello there three ways spring to mind 1, remove the split pin, then carefully weld a 6mm bolt to the cap, clamp it in your vice, and use a slide hammer something like the one I modified to fit the water pump, and yank it out. 2 remove the split pin then carefully using a brass drift, gently tap the plug fully home. Use 320 wet and dry soaked in WD to clean up the bore from dirt and corrosion, when you are happy with it, use a dental pick, or one of those scribing tools with the right angled pointy bit to push the cap out. It will need to be worked back and forth a few times before it ejects, but keep going, you will find it will ease a tiny bit at a time. 3 you can do it hydraulically, tap a hole in a piece of thick plate, and fit a break hose which is attached to a single circuit break or clutch master cylinder, use the o ring to seal it, clamp in a vice, remove the split pin, and pressurise. You will get about 1000 psi, it will go off with a pop, parts will fly, and a proper mess will be made. I have to warn you that highly pressurised fluid is used for cutting steel, so take all precautions for safety sake and film it 😁 it will be quite a bit. I hope this helps
