Blaster engine swap - engine will not align

Wondering if anyone else has run into this before...

I am dropping a 62t engine into my blaster and the engine is about 1/2" too far forward with a dry fit (no dampener installed).

Used my blaster 61x bedplates, and 61x int. bearing coupler with SJ coupler on the crank. The coupler is not properly aligned, and that might get it to work but it does not seem so.

Anyone have a clue or suggestions?

Remember to give at least 1/4 inch spacing. I guess that makes it 3/4 inches too far forward.

And x2 about the midshaft. It's not in all the way.

The short shaft may have pulled forward when pulling the motor out last time or if you had the pump out and put it in, the end of the drive shaft may have pushed it forward. I had this happen to me last year. Like superramjet said, tap it back and you should be good to go.

In fact, you can see in your first picture that there is about 1/4" of shiny shaft showing. I am almost certain that this section was previously inside the housing and is freshly pushed out.

Edit: Oops. Just reread superramjet's post.

just a aheads up, the midshaft should stick out the back of the housing 22 mm

also not to be a wise ass, but you have a good 1/4 -3/8 " if not more adjustability on the bed plates.

Wouldn't you want the engine bolted as forward as possible (assuming the coupler fingers are properly engaged) for weighting/handling benefits? Or would you rather have the engine rearwards to ensure as much spline is engaged between the drive and mid shaft?

Eh? How is engine position related to midshaft position? The midshaft needs to be pressed in one set distance, no more no less - so the spline engagement should be constant, not variable.
Maybe I misunderstood you.

I think the short shaft IS pressed in all the way. Compared it to my SJ and they are, visually, the same specs (on a flat surface everything aligns).

I will reinstall the int. bearing and see if the engine can be aligned by moving the motor mounts.

If that fails, I will remove the washers.

They seem to be washers. I have been informed by the previous owner the engine should drop right in.

Removing the washers should do the trick.
