This won't be the proper way to do it. There is no guarantee you will have a good outcome. If I was there I would have a better feel for what to do. 638 will definitely work without a primer. It is a fast setup product, so primer would make it setup even faster, so I wouldn't use it. I think you should press them together with your jack to help tighten things up along with the 638. I think the press on would help send you towards the hub and sprocket running truer and with smaller gaps. You should check the run out before you mount the assembly. Also it may setup fast but doesn't get up to full strength for a couple days or more. Once you press it on remove the jack and don't even touch it for a good while.
From the company. LOCTITE® 638 is designed for the bonding of cylindrical fitting parts, particularly with narrow bond gaps approaching .00984” The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration.
