Post Subject: Stern Glands

Hi I have been experiencing a leaking stern gland recently and am using a lot of grease to stop it, so I think it is about time I changed the packing in the gland. The shaft is 38mm and the OD of the pusher is 52mm. Subtracting the shaft from the pusher gives me a gap of 14 mm, divide this by 2 to give the actual gap gives 7mm. I cannot find any 7mm gland packing anywhere so far, only 6 and 8mm. My query is: - Is it better to use the 6mm and hope that compressing it will fill the gap, or to use the 8mm and force it into the gap. None of these seem to be the right solution, do you have any thoughts on this matter. Thanks Trevor

Try measuring it in imperial units. I bet its 1/4". It is even possible that a metric shaft has been fitted into an imperial gland. Although you could roll 8mm packing flat so it is wider then 8mm but only 6mm thick I think that I would use 6mm packing to save struggling to get it into the gap. I am sure it will squash down to take up the space. Are you sure simple adjustment will not solve the issue, it all depends upon how much free length is left on the pusher. Tony Brooks
