Volvo Penta 280 outdrive greaser

[ms1]

Trying to replace/improve the tiny 'cup' greaser for the primary drive shaft bearing on the bell housing of Volvo Penta 280 outdrives. Removal of fitting shows a most peculiar thread that I cannot match to a grease nipple (or anything else for that matter). Not metric, it is coarse a bit like BSP, but isn't. So I am a bit stuck.
I used a 12mm spanner on the brass hex to remove the fitting.

I have very limited access to experiment as the cups are at far fingertip reach behind my engines. I can barely see the things (which is why I want to improve the greasing situation).
Anyone know what thread ? Your suggestions appreciated.

Hi

I have posted about this before, what I did on my 280's was to use the existing brass fittings but to drill and tap a thread in the cap of the greaser and fitted a grease nipple in the end of it. Then screwed the cap back on the out drive housing, nipped it tight and job done. When you wanted to grease the bearings just attach grease gun onto the grease point. I used 45 degree grease points but that was probably what I had at the time.

Let me know if you have any further questions.

That is brilliant Peanuts. I think I May go one step further and fit a hydraulic hose to the fitting so that the nipple is up above the bellhousing.

thanks Peanuts
what a good solution.
I discovered that the thread is M10 with 1.5mm pitch and such grease nipples can be purchased from specialist suppliers.
