Hello,
I want to exchange the transom gimbal bearing grease fitting.
The original part-number of Volvo Penta is 3852121.
Its a OMC Cobra SX 1995.
At the moment it is hard to find it in our shops (germany), so I want to replace it with an alternative auto-part, but I need the dimensions and the kind of the thread.

Did someone replaced this part in the past?
It would be very nice, if someone can help me.

Thanks a lot...

You just want the dimensions on the original fitting? On the newer drives the fitting is connected to an extension tube, and I think the fitting and tube come out together just by pulling on them. Maybe yours does too?

Hello,

thanks a lot for your reply.
Yes , I want the dimensions of the original fitting.
And yes, there is a tube. The OMC SX transom is similar to the Volvo SX.
I our shops I can only get metric fittings, but I'm convinced I need one in inch size.
So I have to order it in the correct size online.
This is the reason why I want to know the diemensions exactly.
Furthermore I need to know the kind of the thread. In pictures on websites it looks like a UNF.

I might be misunderstanding, but can't you just pull yours out and measure it (or are you saying someone else already replaced it)?

At the moment I can't.
The boat is winterized and far away from my hometown in a hall.

My Idea was, to buy all the parts I need, before I drive to the boat.
I'm conviced, that there was nothing replaced in the past.
It must be the original fitting.

Ok, now I understand. Unfortunately mine is far away too.

Any idea Lou?

I don't know which thread it has, but here is a source that shows pretty much all of the possible grease fitting types and sizes:
