12a Rebuild

[shaunwil]

I\'ve always wanted a 12a engine to take to bits and after a good day at kev_yorks i now have a spare 12a to play with. The engine is a runner and is very clean. There is compression from all faces when i turn the flywheel by hand and the tips look in good condition through the exhaust ports. I\'ve taken all the auxillary bits off the engine today and got an oily floor !!!!

First question is how tight are the front bolt on the oil pump and the flywheel bolt. Am i better off taking them to a garage to get loosened off ?

Will hopefully be stripping the engine over xmas with grinder and then getting it inspected by wgt.

Pictures so far :

If its the same as the 13b then the flywheel nut will be aprox 280FtLbs

Susssshhhhh the PP is for the engine already in the car if this engine isrebuild able

Definately looks like a fun xmas project !!!!

What special tools do i need to break the engine down ?? Investigating getting an engine stand adapter made, but need to measure up and get drawn up in CAD.

So how many of these engines does Kev actually have? didnt he give one to Alban a few months ago??  KEV dont suppose you have any spare 20b stuff do you???
 Cant remember actually needing any special tools but that was just me pulling engines down on the driveway! not especially proffessional.

you can make an adpator that locks the flywheel onto the engine - so that you can get the nut off

failing that - a 8 foot breaker bar

Kev had 3 engines, ones gone in alans turbo, ones gone to me and the other was stripped by kev (i think). He bought them as a job lot !

Going to draw up some 5mm plate and give my old boss a call !

I cracked the flywheel nut off with a long breaker bar (probably about the length Grinder said!)  Must anchor the engine else your effort goes in the wrong place!

Other than that it\'s just regular tools untill you come to check the tolerence\'s.

Good luck :cool

i will be helping Shaun strip this

i think he got bored of waiting for me to do mine - so he got his own !!

Here\'s my "adaptor" and "breaker bar" :rollin

[travellinbob]

Thats how I got mine off but I snapped the nut!

[antnicuk]

thats just wrong!!!!!    

that poor engine!

i borrowed an electric nut gun,  that does the trick in seconds everytime.

no special tools needed to pull it, just do slowly and carefully otherwise all the bits go everywhere and you learn more.
