Harmonic Balancer

90lbs (boxwrench.com)

Don't forget some assymbly lube on the seal and the balancer before you start.   You'll also need something to hold the crank still, I've been using a belt tensioner to hold onto the flywheel bolts to turn turn and hold the motor, works pretty good.

Ok it seems to be about 1 notch out shall post a photo for anyone else looking to change to a left rotation

So my new balancer turned up from the US I'm looking to install tomorrow, what's the general consensus with greasing the crank and installing it via the crank bolt? Will I get away with it if I'm careful?

Also regarding timing marks, its a lefty but TC seems to be in the same place as the original right rotation one. Does this sound right? If so I can just treat BTC as ATC and vice versa without the need to buy a new timing mark sticker..

Thanks

Graham, I use these UK suppliers......
These guys are the Sierra agents UK ( Patten parts ) which covers many PCM ford parts and can cross ref to Sierra.... Keyparts

The London Nautique dealer has a stash of old PCM parts too.....Nautique Marine

Thanks Roger! I actually bit the bullet whilst at the airport and went for that one on ebay but it's still very handy to know of any UK based companies for getting hold of future parts.. or worst case if the balancer I just bought is no good..

Whilst we're on the topic do you have info on any other local companies that may help with nautique or ford specific stuff? I'm always keen to avoid throwing money at import duty where possible

Graham, in playing around on Summit Racing's website, there are only a few 1990+ 351w's that used the 50oz external imbalance. All others used the 28oz. I'd say its a pretty safe bet thats what you have.

I posted pictures of my old balancer here:

Is it possible to tell from these whether or not its a '28oz'er, the same as my ebay link above?

Thanks both, Mark mine is the 3 hole variety but it seems that I need to measure up before committing to a new one.
Roger thanks for the link I shall give them a call, hopefully they will know from the ref# on my old balancer as they seem pretty clued up..

No 28 oz is the amount of weight removed from the harmonic balancer ring on the outer circumference the whole thing will weight close to 10 pounds. the 28oz matches the weight added to the flywheel on the back of the engine. That Ebay balancer has 3 bolt holes for your WP pulley, alot of 351W's have 4 bolt holes, so make sure your pully has the same number of holes as the balancer. Also make sure the mounting depth from where it bottoms out on the crankshaft snout to the fron face where the pully bolts on is the same as yours, or you will have alaignment issues with your belts.

Just put a peice of normal rotation timing tape on backwards and you will be all set.
