Hi All,

Just wondering what the approximate weight of a stripped 12a engine is. I am just about to start a rebuild and was wondering about the weight of the engine and what I should look forward to during the rebuild.

Any ideas?

thanks

Why do you need the weight, its not gonna be easy to lift its >200 lbs.

Thew rebuild is simple, but you will most definately need parts

KYPREO

A straight 12A block dry will be under 100kg (220lb).

Thanks for the info on the weight, it was just something I was wondering about. I figured I was going to need a few parts so I just sent off an inquiry about a number of them.

Any ideas as to how easy it is to build the plate for the engine stand. I have read about a few people building thier own.

Being 6ft 5, and having a weak back- I don't consider 220lbs easy to lift- especialy when bent over an engine compartment.

My thoughts exactly!

That's why three of us with steel polls and chains are going to lift it out. If it seems to still be a bit much then I am off to the store for a cherry picker! Either way, she is coming out!

Just rent one..... there's nothing like having the right tool. I won't cost more than $20.

TheMoonDog

Thought about that and checked it out. They wanted half the price of buying one just to rent it. Thought well, the engine can't weigh that much!

Just use dynamite to get the engine out. Thats what I would do. It's so much more fun.

TheMoonDog

Hmmm, now how much wieght in dynamite would I need?

Look around at garage sales for one. I got mine at a garage sale - had been used once - $80.

That wasn't just from a refundable deposit?

Regardless of the weight of the bare block (my aviation rotary contacts put the bare block weight of the 13B at around 180 lbs, so the 12A should be slightly less than that), you'll need a lifting device. I once used a come-along attached to an overhead 4X6 wooden beam which was laid across two step-ladders. Just hoist the engine, then push the car out from under it. (hood removed of course). These come-alongs are cheap to buy and even cheaper to rent. Not as convenient as a cherry-picker, but will get the job done.

re-building an engine is not too too easy...and it is usualy cheaper to buy a new one from mazda or a slightly used one out of a car...if you have blown an apex seal...imagine having that rotor flying around at 3000rpm...and then imagine throwing a piece of jagged metal in to the engine...its nasty....i took apart a blown engine once with the intention of re-building it...and to make a long story short...the rotor is a paper weight on my desk...it looks like it was shot with a shotgun...

The_Dude

Mine's exactly the same ... Once u bust a rotor, not much you can do with it... + , usually, if you bust the rotor , the cylinder ( rotor's housing ) is all screwed up too ... Hope your's all still all good cuz a rotor + cylinder is 450 $ here in Canada ... :P Ne ways , take care peeps !

yea there around 200lbs. not to heavy compaired to a piston motor. i just man hadle the motors. when i have to move one of the 13bs i have sitting in my garge i just put a strap on it and pick it up by hand and move it. long distances can be a bitch though.

We tried that once... I got a driver sides fender when you need it,

Your better off getting the car way up in the air, and lower the motor to the ground and rolling it out from underneath.

bliffle

I was wondering if that would work. How high do you have to get the car, and how much comes off first to clear?

carb, alt, dizzy etc, the car would have to be about 2 foot off the ground.

Still gonna have to have a hoist to get it in when you are done with the rebuild.

Or be able to benchpress a lot

Well, as it turns out we didn't need to pull her out after all. A johnson bar and the ATF trick fixed her. The problem was that she wouldn't turn. I thought it was seized and was going to pull her out and rebuild. As it was, she was just being a little difficult after sitting for a while.

Thanks for all the comments and jests.

Check this out! During my quest to fix her I came across an 82 GSL with two extra engines an extra tranny and whole pile of other parts to use on my 82. I just finished the purchase for $500.00 CDN. Now there is deal! What do you think. Is it a deal?
