Underdrive Pulley Questions

[Ben006]

There are tools to lock the flywheel from the starter crown gear.
And without the flywheel, there are tools to hold the crankshaft by the flywheel mounting holes.

But without the pulley and the locating boss, finding cyl 1 TDC takes longer.

And which is why we have a substantial surcharge on IMS retrofits or any cam related work on cars that are already fitted with under drive pulleys. If I have to pull your trans to do a job that normally doesn't require it (e.g.: VarioCam repairs), you are going to pay for the privilege.
