First you will need to get the grease nipple to line up with the hole in the housing. I haven't had to do this yet but suspect that it involves either a lot of luck when you switch the engine off or taking out the spark plugs so that you can turn the engine over by rocking it in gear till it lines up then get a grease gun on to it.
Also suspect that it will involve some bad language when trying to get it to line up.
