Im almost done with this project I need to add the capacitors on the motor brushes I read that the specs should be Non-polarized 1uf, 50v. would any of the capacitors I have work? same voltage just different uf readings.
Also can the capacitors be installe in any direction? one side has a stripe? is that the positive side?

You can't use the ones with the stripe, there is no "positive" for an AC motor. You MUST use non-polarized caps, those will have no stripe. Also, you don't want to put too much capacitance from the brushes to ground, get the right caps.

lastly fix the LCRU-2 I robed the part form would this work as a replacement? thank-YOU

Not even close, the part you removed was a triac, and this is a MOSFET!
