Cylinder cladding Empty Cylinder cladding

Post  Bertieburrell Wed 11 Mar 2020, 4:33 pm

At the moment I am test fitting the cladding to my cylinder on my 4" agricultural and have come across a problem.
The brass and cladding are drilled to take 6ba, the fixings supplied are 6ba but the cylinder itself is drilled and tapped to take M6.
Am I missing something or has anyone else encountered this.

Might be a packing oops.
Call STW and check with them. They will send the correct fastenings.

Thanks for the reply lynn I could have understood that but the cladding and brass are both drilled to take the 6 ba too.

I'm pretty sure there are m6 inserts that go into the cylinder block first and then the BA screws screw into the insert.

Yes you need to put the brass inserts in first and then put the BA bolts in.

The easy way to do this is to pop a nut on the BA bolt, then screw that onto the insert and lock it on with the BA nut, then screw the lot into the block and then back the nut off and unscrew the BA bolt back out.

I personally wouldnt put any loctite on the inserts or the BA fixings, the brass BA bolts can snap off, cross thread very easily, trying to drill a snapped off bolt out of the insert is a total mare when its locked into cylinder, been there done that as I had two that "someone" had snapped off Rolling Eyes
Mine are not loctited and I dont have any probs with them coming undone. While you are messing about with the cladding if fancy it then drop some insulation between the cylinder and cladding you can, I use the ceramic stuff. I find it does help protect the paint on the cladding a bit. Dont put it under where the fixings go though as that makes assembly even harder than it already can be.
