Drilled off center. Supposed to bolt a pulley to this.

After 160,000 miles, the 302 cu. in (5.0L) engine blew in my 1990 Ford Bronco. The crankshaft in the motor literally snapped directly under cylinder #1. I swapped the engine with a remanufactured crate motor and when I went to time the motor with my timing light, I couldn't see the timing marks at all where they should be. After much research, I determined the likely culprit was likely the OEM harmonic balance I reused from the old motor had failed. This turned out to be true. The outer ring on the OEM balance had rotated off from where it should have been causing the timing marks to be completely off (see pictures). The failed OEM balancer was likely the cause of the blown motor as well due to it throwing the engine completely out of balance when it failed.I purchased this unit and it installed easily. I simply applied a small amount of grease on the crankshaft and gently pulled the new balancer onto the shaft with the retaining bolt using a 1/2 drive socket. The unit pulled right on with no problems and everything worked perfectly. Some people reported they needed an harmonic balancer installation tool to prevent damaging their new balancer during installation. I didn't have any problems installing it the way I did. Maybe I was just lucky but others said they didn't need the tool either. In the end, I was able to time the engine without any further issues using this new Dorman balancer.I've never had the problem above happen to me before, but it appears many others have. For this reason, I'm planning to replace the harmonic balancer every 50k miles to make sure it never happens again. Some may think this is overkill, but compared to replacing an entire motor because of a harmonic balancer failure, this is nothing.Thank you for keeping my old Bronco on the road Dorman Products!

I'll buy one of these everytime I do an engine!

Install was a breeze, as long as you borrow or buy a puller/installer tool for the harmonic balancer.

So far so good. It has only been installed on the engine for about 100 miles. This part is like for like compared to the original Ford part installed in my 1988 Town Car. Of course this one is made in China but so are most of the parts for a car of my vintage. But on the bright side of things, at least new parts are available at a very reasonable price. I used a fine point white paint stick to trace over the timing marks and the timing numbers to enable to set the timing with a timing light. If you don't trace the timing marks it will be almost impossible to see the timing marks with a timing light. Be very careful installing this part. Start the installation process it with a balancer installation tool, then finish the installation with the bolt that holds the balancer on the crankshaft. This way you will not push the balancer in too far. It will only go in as far as the attachment bolt allows. If you push this blancer in too far you will push the timing gear on the crank shaft into an indentation in the block and the timing chain will snap. Luckily the stock 302 V8 is low compression with low valve lift, hence a non interference engine. I was advised to put a small amount of RTV silicone Permatex ultra black on the Woodruff key since it is part of the front oil seal. This balancer slides over the end of the crank shaft easier than I thought it would. Even Summit racing sells Dorman parts and their technical support center representatives speak highly of Dorman parts.

Overall this damper seems good, paint job was sub par but I'm not building a show car, can repaint easy, fit was good
