I am thinking of retiring at 62 which is my early retirment age for S.S. Can I start withdrawl from my 401k at 62 without any penalties?

That is something you have to check with your plan provider about, as each plan can have a different age limit for withdrawal without penalty. Mine is 59 and a half. Ain't there yet!

If you are "separated from service" at age 55 or later, there is no early withdrawal penalty from your 401(k). So at age 62 you will not owe any penalty. You will of course have to pay income tax on your withdrawals.

First, you shouldn't piggy-back your question on top of someone else's - you should start a new topic instead.

Second, contact your plan administrator to find out how to take a withdrawal. Alternatively, it may be a better deal for you to transfer the account into a roll-over IRA, and then withdraw the money from there. Reason is that if you use the money for certain "hardship" purposes (such as to prevent foreclosure on your home) the withdrawal from an IRA does not trigger the usual 10% early withdrawal penalty, whereas withdawing directly from a 401(k) does. So, what specifically are you going to use the money for?

At age 62can I withdrawal half my 401k and not have to pay back and will not owe any penalty.

Yes - assuming you are no longer an active employee of the company where the 401(k) is located. If you are still employed there you will have to ask the plan administrator whether at age 62 you are allowed to take an "in service" withdrawal - plans vary so they may or may not allow it. Also keep in mind that you will owe income tax on the withdrawal (federall as welll as state/local if appropriate for where you live).
