Volvo Penta Pivot Bolt Spline Tool

[baker556]

Hi Guys,

From googling the VP pivot housing spline tool I'm receiving conflicting results, please can someone help clarify or even better link me to one.

The research has me to believe this is a 1/2 inch Allen Key or a 1/2 inch spline tool this would be a 12.7mm spline tool? Others say use a 14mm spline tool?

Help me out.

Thanks

I have always used the MerCruiser hinge pin tool.

To try and help with this question a bit better, this may depend more on what model stern drive & transom assembly your boat happens to have.

My dp-sm uses a 1/2 allen key.

ah sorry guys it's volvo penta SX-M

@ Muc, I was told that this wouldn't work, do you use the following:

I wouldn’t recommend aftermarket for this tool. I have used the OEM MerCruiser tool hundreds of times on a SX-M.

 

[baker556]

muc are you saying the spline tool I linked would work or not?

Thanks

I don’t know if it will or won’t. What I’m saying is that for this tool, I would recommend buying the tool from MerCruiser. I have no idea the quality level of the tool you linked to.

So here is the dilemma.

Most people suggest a 1/2 inch allen key and this works, I've tried it - I'd like to torque this back up with a 1/2 inch socket.

The issue is, the torque is quite high and I do not want to strip the thread, to get hold of a 1/2 inch hex head on a socket is either a 12 or 13mm but most users suggests using a 14mm hex. Is this correct? Or is this meant as a 14mm spline tool and as a 1/2 inch allen is 12.7 mm.

Thoughts?

 

[baker556]

Right from further reading, I think I've had this info wrong. From another thread someone suggested a 14mm but infact I'm lead to believe they meant an M14 = 12.5mm.

I've ordered a 12.5mm, I will update this thread.

Stop messing around with metric and imperial. In the VP manual it states use a 1/2 Allen Key.

 

[baker556]

Yes but how do you get a 1/2 Allen key into a socket to torque?

 

[muc]

Some people buy a socket that has hex bit in it.
Some use a hacksaw and cut 1” off the allen key and put it in a socket.
Some hire a pro to do the job for them.
And others use the MerCruiser tool because it fits better.

Nice one muc.

Some use a hacksaw and cut 1” off the allen key and put it in a socket.

Actually the best result, cheers
