Re: harmonic balancer

The harmonic balancer on the '29 Standard eight does not look like that one in the photo which I guess is from a later model. The '29 balancer is bolted to the front of the fan pulley with 6 bolts threaded into the pulley and is centred by a light press fit onto a shallow spigot on the face of the pulley. The balancer needs to be pulled away from the pulley and this may be achievable with a couple of wedges 180 deg apart but bear in mind the fan pulley is quite fragile and easily cracked. Otherwise a large 3 jaw puller will be needed.
The crank dog does not hold the harmonic balancer in place and in fact does not need to be removed. The centre of the harmonic balancer is clear of the crank dog. Its all very confined and if the engine is still in the car the radiator will need to be removed.
It is also worth mentioning that the cross sectional drawings of the 626/633 engines in the handbook and parts book show the harmonic balancer behind the fan pulley (in between the pulley and the engine) however this is not correct, its on the front.
