Take thats just the keyway for the front pulley? If it is new key welded in place tidied up with a die grinder front pulley back on and bolted up tight. Should be fine like that.

Sorry I can’t work out which pulley it is but how often would it need to be removed? If not often can you just weld the pulley on to the shaft, very bodged but maybe a fix and forget repair. Not sure if heat would damage any oil seals behind.
You may of gone through all this but can’t remember much about threads these days.

Don't know the 2.8 so well but I would imagine you might need to remove the pulley to get the timing cover on or off (cover is currently off) :nenau

So are we looking at this as the only problem. The shaft has had the keyway damaged?

 

[solarman216]

Welding the pulley to the shaft is not an option, it would not last, providing the shaft is not worn diametrically then I would be removing the cam belt drive pulley and cutting the shaft to take one long key all the way to the front and then fit a new pulley, if the shaft is worn then you could use a bearing loc goo but it might not last, better would be remove the shaft and have it machined properly, Rick

Left it on charge overnight and started it this morning, started no problem at all and even managed to take the girlfriend around the new housing estate in it albeit a bit tiring with no power steering, it's a big heavy beast!!!!!

That was a big risk Zac, if that sprocket came loose, good by engine, bearing in mind there is nothing holding it on, just the wood-ruff key, , Rick

Been doing some research on this problem Zac, seems many people that this has happened to state that the crank bolt was still tight, so looks to me that maybe the bolt washer was fitted the wrong way round, it has a relief for the crank end if fitted the correct way, if the wrong way then the washer will be tight to the crank but not to the pulley, also to get round the bad key way you can drill two or 3 x 6mm holes into the crank/pulley and insert some good quality steel rod into the holes, and make sure the pulley is clamped before the washer touches the crank, Rick

You couldn't knock me up a crude fag packet drawing and take a pic and post on here could you Rick, I can't really picture it? Don't worry if you can't, I can't draw either :lol

 

[solarman216]

Your wish is my command, Rick

 

[Banshee]

Cheers Rick, is this an engine out jobbie? Or a repair I can do with it in the truck?

 

[solarman216]

If the pulley is a good fit on the crank, not wobbly, then yes in the car fix, Rick

 

[solarman216]

new pulley are available on Ebay for around £100, Rick

Yeah I've seen that one I think if it's the Febest one :naughty

 

[solarman216]

Are they not up to scratch then Zac? Rick

The ones on eBay look just the job, it seems that the original has fared worse than the damage to the crankshaft so will be replaced.

Rick if you read back through some of the previous posts I posted a short YouTube link to a Russian guy that had done the repair that you suggested funnily enough and will probably be the route I go with it.

I'm not sure I'll keep it any great deal of time when it is repaired as I really really dislike the LWB they are ugly!!!! I'd happily chop it in for a shorty though and mod the hell out of it but these seem to be so so rare :O

All going to plan I should have another 2.8 engine with 80k miles on it on a pallet in my garage by the end of the weekend :naughty

Watch this space

 

[Mr K]

WHAT! How did you manage that?

I've got a real soft spot for that 2.8 engine, was just thinking about it the other day, I wouldn't say no to having another in the right car.
