    Engine alignment question

    I installed my engine today and I get how to do the side to side and up and down alignment. My engine shift slightly front to back does this matter? I push it as far as I can up to the front and bolted it down and installed my carbon ring. I don't think I could have installed it if the engine was any closer to the rear. The PTO rubber bearing that goes over the carbon seal the flap thing is literally right over the bellows where the carbon seal is it seems awfully close compared to the 3-foot video that is on YouTube of the alignment procedure

    Drive shaft must have around 6mm of play without floating ring on.

    Do a search for “longitudinal axis” as there is much info about this topic.

    Bottom line, your drive shaft should have no more than 1/4 to 3/16” play in the drive shaft.
    Mark the drive shaft with a thin marker in front of the impeller, then have a helper pull the drive shaft toward the engine until it stops, Mark the shaft again. Too much slack will not put enough pressure on the carbon seal, allowing the c clip to pop out! Too little slack can damage the thrust washer and internal engine components.

    A shop manual for year and model should always be used!

    Thanks guys. I do have a manual but didn't see anything on front to back alignment. From what you guys are saying it sounds like it's fine but I'll measure the shaft. With the alignment tool connect to the PTO adapter I measered 29. Whatever the 2 measurements are but the adapter kept going in the PTO to tightly and getting stuck.
