Read articles →This is part twelve of a multi-part DIY series documenting a 4th and 5th SCV install on a 4052R, focused specifically on connecting and routing the SCV coupler lines. It covers the fiddly hands-on details: order of installation, using a pry bar and a modified tool to fit lines past the rockshaft, spacer and hose clamp placement, and final handle adjustment. Best for owners already mid-install who need troubleshooting tips on this exact step, not a general overview.
Posted by the HubTime channel, an owner documenting their own DIY SCV installation rather than a dealer or professional mechanic.
Install the top left first, then top right, then bottom left, then bottom right, following the order given in the book for that side.
Use a pry bar to hold the square part of the line, and a cheap tool cut short so it clears the top of the rockshaft. Removing the third arm holder helps too.
Raise or lower the handles to bring them to the full straight upright position, then lock them down with a 4mm hex drive cap screw.
