Engine sits too high

[RivMan]

Hey guys,

I've been trying to get the driveline on my ROK aligned properly after my recent driveshaft / midshaft failure. I've aligned the pump / midshaft to perfection using a CF midshaft tool, so I know they're in good shape. My next task has been to align my engine to the midshaft (CF couplers).

The engine seems to be sitting about 2mm higher then the midshaft coupler. I've increased the size of the motor mount holes in order to move them away from the motor, but that only got me half way there.

Any tips on dropping the motor a little more without shaving down the mounts?
How close is close enough?

Thanks

Rhaas can make you custom height mounts...

Loosen bed plates on crankcase and push them into engine, maybe also elongate holes, re-tighten crankcase bolts

Machine your cradles. Also loosen them up and see if you can slide them in. This can help lower the overall height.

I'm trying to avoid replacing mounts (I already have a set of Rhass mounts on the ski). I'll try the bedplate trick, I never considered that.

Thanks

You can machine the bottom of the bedplates (surface that rests on the motormounts) or the top of the beplates (surface that the cases rest on). You may also be able to open up the bolt holes on the midshaft then shim the front ears of the pump to lower driveshaft.

What motor mounts are you running? Are they couch height?

 

[RivMan]

I'm not sure what mounts they are, they are unmarked Rhass mounts. I have a set of SJ and a set of Couch mount's I'm going to compare them too tonight.

The SJ ones should be the shortest. I believe your couch mounts will be 2-3mm or so taller than the SJ ones.

Deck the bottom of the mounts on a belt sander.

Thanks guys! Hopefully I can get this all taken care of to hit the water for the holiday weekend!
