Au Falcon front engine pulleys (Read 1,455 times)

[General Melchett]

hi all long time listener 1st time caller, ive got me an AU falcon engine and the car i bought is an EA, i am wanting to run the vee belts off the ea, (i got no p/steer pump or alternator with the au), ive changed all the waterpump, p/steer pump dizzy, inlet manifold etc etc off the ea but am told i cant run the ea front crank pulley and have to use something else, does anyone out there no which pulley to use, i was told an ef front pulley with an xd p/steer pump pulley bolts to it it, is this correct and if so does anyone out there have some spare ones laying about they would like to exchange for some dolero's thanks in advaaaaance, baaaaaa

Hmm, I just used an EA front crank pulley on my AU, went straight on.

You can use the EA crankshaft pully on the AU motor. However, if it is the type of pully that has two vee's and then a multi rib part behind them you need to machine off part of the multi rib. Machine about 5mm in and 5mm down. If you don't do this the back of the pully will hit the crank case cover.

[General Melchett]

ah thanks 29s, yess i have the type that has the two vee's and the multi ribbed( ), so once it is machined i am presuming the waterpump/crank pulleys will all be in line as per the norm ??

[Saloon29s]

Should all be lined up. You may have to put a small spacer behind the water pump pully though. I had to put a 2mm spacer behind mine. (just cut it out of a 2mm piece of alloy). Make sure you use the EA adjuster that bolts to the head as well.

Took alook at mine today, I can see were it is close to the front cover, but not touching, and no mod to water pump, (EA pump) I know of one other car this was done a few weeks ago with no mods, sounds like some just pull up closer to the engine than others, have a pulley puller handy and just take a look at it.

[Saloon29s]

If the crank pulley has gone back, then wouldn't the water pump pulley need to go back rather than forward??

[ross]

Ah yeh your right! But my EA one still don't hit anything!

[Saloon29s]

I must have a wonky engine then lol. ;D

[General Melchett]

have machined the front EA pulley and fits like a glove, only problem is now that when i went to fire the engine it did about 2 turns then stopped, removed the g/box and engine turns over ok by hand, is the au timing the same as an ea?? ie when number 6 valves are rocking and the dizzy is ponting at 1 is that correct???, got rather sh**ty with the gearbox tho (HQ), any ideas why it wont turn??, rear shaft turns ok but front shaft is jammed, you can turn it ok in the opposite direction but when you turn it the right direction it just jams up, havnt taken the cover off to look yet, too pi**ed off at the moment

[Saloon29s]

Not too sure on that one. When we changed from the ea to au had a similar sounding sort of thing happen. The problem with ours was the dizzy. I think it was the gear on the dizzy not meshing properly with the gear in the engine (bit out of my depth here). So would maybe suggest looking at the dizzy as a starting point. Ross94 may be able to help with this one.

[Saloon29s]

Just been re reading your message, i would definatley start looking at the dizzy first.

[General Melchett]

sorry it was the gearbox binding up, engine turns over fine, just the battery was too dead to fire it, g/box removed lying on floor after the recieving end of a sound thrashing, thats where the jamming problem lies

[Saloon29s]

Ahh ok then. Just been doing some offline research for you anyway. Apparently with so Au's the shaft on the xf dizzy is slightly too long and can bind up therefore causing the gears on the auxilary shaft to strip so just be aware of that. Actually just had a thought that maybe some of the xf dizzys have a slightly longer shaft? Have heard of some people running them without modification and others having to machine 2 or 3 mm off the end of the shaft. Hows the gearbox?? Not too bashed I hope.

I think that the TDC mark on the AU is also in a different place than your EA pulley,Might have 2 TDC your engine & check your marks otherwise you might not have the correct timing etc.
