Superjet Engine Shims Different Thicknesses on Front Two Motor Mounts?

[jpswift1]

I've shimmed lots of Superjet and Blaster engines, but I've never seen this one yet. Everything is lined up as far as the pump and midshaft go, but when I put the engine in on this one, the rear two engine mounts didn't require any shims, the front left required one .5mm shim and the front right required one 1mm shim. The coupler is lined up perfectly all the way around, but I found it odd that there are two different sized shims required to get it this way on the front left and front right. Is this normal? Will this cause any issues down the line from now or should I just run it since the couplers are perfectly aligned?

If it’s aligned torque it down and forget about it

Thanks guys. I was just surprised because I never saw a set up with different sized shims on the left and right sides.

I see different sizes of shims like that all the time here , that is why you mark where the shims go when you remove them.

I bought this Superjet as a bare hull, so that wasn't an option.

You can also adjust motor mounts. Push in towards center line to tighten up.

If they were perfect there would be no need for shims, guess what they are not perfect
