Absolutely not. Once everything is reassembled, off center shafts, or engine cases, will still force side loads on the bearing as the real problem has not been addressed.

Removal of the hydraulic tensioners is essential during an IMS retrofit because not removing them, as many have discovered the hard way, forces the shaft to one side and prevents removal of the bearing, and can also lead to one or more chain jumping time, which leads to no end of problems. We have had more than one totally failed retrofits flat bedded to the shop because the owner’s never bothered to read the instructions for doing a retrofit, and then ended up paying us thousands of completely unecessary dollars to put the car back together.
