Any sugestions on removing whats left of the balancer? I'm going to run the tap drill into the crank to spot the center of the broken bolt then use the screw extractors to hopefully get it out. The balancer piece i'm not so sure! i thought about popping the seal out and try to get some sort of puller on it.

Well that stinks :mad:

Seems to me the center bold might come out with a pair of needle nose pliers if your lucky since there is no tension on the bolt.

The HB collar is a total different story, maybe a punch to see if you can shatter the collar off ?? Be CAREFUL not to scratch the crank though.

I have a ultra clean low mileage early model factory balancer if your interested.
PM me for details and good luck with your project.

Use a angle drill with a reverse (left hand) drill bit about 3/8"stay off the threads it should come right out.

i carefuly took a 1/2" drill into the broken bolt to locate the center

Then i drilled a 1/4" hole into the broken bolt and remove it (easily) with a screw extractor

Then i drilled small pilot holes across from each other in the remains of the balancer and ran 3" sheet metal screws with washers in and use a cheapo $10 steering wheel puller

NOTE be very very very careful when drilling into the collar i put a nick in my crank shaft ! BUT the seal rides on the balancer so i cleaned it up with a file and all is good. Just be aware of this as it is EASILY done when drilling at funky angles

Well done, MacGuyver! Those screw extractors really come in handy. It's difficult enough to get the main bolt out with prime circumstances, let alone less than ideal ones. When i'd removed the balancer/ crankshaft pulley to replace it with an underdrive on my other car, to get the main bolt loose, I had used a tire iron (same size of bolt head) and even with all that leverage, it was ridiculously hard to break loose.

I cant remember if my center bolt broke but I don't recall having a hard time with it. However, instead of doing the extraction of the remainder balancer piece in the timing chain (didn't trust my skills with the drill back then) I just ended up removing the entire timing cover. Did some clean up, new gaskets, WP and balancer. With the timing cover off the broken piece of the balancer just slides out...no risk of dinging your crankshaft. Only bolts hold the timing cover in place and the only other tricky part is re-aligning cam synchronize but no problem if you have the cam tool.
