motor mounting question

Postby JTaylor » Mon Mar 04, 2019 9:38 pm

I have a question about mounting the motor to the base plate. Our old car had a flat plate and 15 degree brackets installed to tilt the motor. These slanted brackets are threaded in several places and allow you to just set the motor down on 4 all thread bolts. This year we have a new to us half-scale and the back half and motor plate are already on a 15 degree angle. The motor plate only has slots for adjustment. I cant use the all thread unless i put nuts on top and bottom. Is this correct or do you just use bolts with washers up through the bottom of the plate and nuts on the top to hold the motor? Or am I missing something. I hate stupid questions.
Thanks

The newer Halfscale cars use a dogbone with two pieces of all thread threaded into them that fit up from under the motorplate. This way each pair of studs are tied together and slip up from the bottom side of the motorplate. You can tell if it set up for this if the bottom of the motorplate has a machined recess in it. If the bottom of the plate is flat, just use a bolt like Destiny's Dad said.

Halfscale has the dogbones and they are cheap.
They make lining up the bolts with the holes in the block easier.
Once you have the bolt on one sided threaded on the other side is already in place.
Much quicker and stable.
