Installing pressure chain tensioner 4-6 how do you maintain tension?

[BGCarrera32]

Hey experts

3.2 Carrera rebuild, timed my cams, bled my Carrera tensioners and am ready for the swap from the Stomskis I used to time the engine. I'd like to maintain tension on the right bank chain 4-6 so I keep the timing spot on and can make the swap (same line of thought as Wayne's rebuild book).

How do you guys keep tension on the idler arm for the swap on the right bank (pictured)? I can't come up with a good leverage point or clamp that will stay clear of the removal of the Stomski piece and not interfere with the install of the factory unit.

Thanks!

A wire around the idler arm axis up to the stud above. Then twist until you have light pressure. There isn't any force causing anything (crankshaft, camshaft) to turn, so it just needs to be secure.

You da Man- thank you. That did the trick.

There is a specialty tool but you can make your own using two exhaust nuts and a short 8mm stud.

Thanks Henry. I have a tool similar to what you show in your top image and got it to work on 1-3 but, was struggling with it staying put on 4-6; I probably don't have exactly what you show there. Thanks for the pics!

If the crank is at #1 TDC, the cams just sit there unless you try to turn them. This is with all the rockers installed and basically stock cams with the cam timing properly set.

Yes, and if the cams are already timed, you don't need to worry about a little chain slack while changing the tensioner - timing won't change unless you skip a tooth, but that's easy to avoid...
