How to replace an harley 1998 roadking timing cover
If you're talking about the "nose cone", you can sometimes take it off and get another back on without taking the pushrods out. I've done this on an occasion or two.
Start by taking the small plate off the timing cavity where the ignition pickup is located. Mark both the plate and inside of the timing cover in a way that you can get the timing set as close as possible with the new "nosecone". I'd suggest taking one of the standoffs that hold the plate in and marking the plate with the centerline of the bolt hole, When you put it back in with the new nosecone, since it will not be marked, align the mark with the centerline of the bolt hole in the new cover. Then, take the other standoff out and remove the "timing cup" you find under the plate.
Now, take all the bolts out of the "nosecone". They are different lengths so make sure you make a note of which bolt goes where. Look back near the oil pump and you'll see a small ledge of the nose cone that extends over the crankcase edge. Use this area to gently pry the nosecone away from the case slightly. Once you get a small gap on that side, work a putty knife around to the other side. There is a dowel pin right at the top point of the nosecone. Now, as you work the nosecone off the engine case, you must hold the cam to the inside of the case and not allow it come move forward. If it does, the tappet rollers will fall off the lobes of the cams and you WILL have to remove the pushrod then. Gently continue to pry the nosecone off. Once the nose cone is off, make sure the plastic shim on the plastic breater gear is on the end of the gear. If not, use some thick grease to "stick" it back on the gear. Make sure there are no teeth broken off the breather gear as well. DO NOT REMOVE THE BREATHER GEAR NOR TURN THE ENGINE OVER WITH THE NOSECONE OFF. If you do, you WILL have to pull the pushrods.
Now, install a new gasket, lube the bushings in the new nosecone with some oil, and start it on the crank end and the cam. Push the nose cone up into position making sure the dowel pin is aligned. Then, you can smack the nose cone at the timer cavity hole and generally it will pop back on the engine cases. If so, you lucked out provided you didn't change the timing on the camshaft or the breather gear. That's why I told you not to remove the breather gear nor turn the engine, to keep everything properly timed.
Now, if the nose cone popped back on like it should have, you've lucked out. If not, you'll have to pull the rocker boxes, the rocker shafts, and the tappet blocks to get the new nosecone back on the engine. When you reinstall the tappet blocks, you'll need a pair of tappet block alignment pins to get them properly aligned.
You'll have to do a bit of electrical work to get the timing sensor out of the old nosecone as the wires will have a plug on the end. You'll have to "unpin" the plug and the repin it correctly once you get the wires in the hole of then new nosecone. Then install the timing cup and the timer plate aligning the mark with the hole. If all went well, your bike should start and run well.
