SSR_X going again part 2

[stormrider]

After walking the dog and thinking ,the only thing left was the injection pump.So I started stripping it out.Start at the top and work your way down to it.All went well until I removed the camshaft drive pulley thats bolted to the injector pump drive gear.The nut that holds thepump shaft into the gear didnt seem to be very tight.Alarm bells started ringing.The shaft is tapered with a key and needs a special tool to split it from the gear.This one just pulled out by hand.The key fell out and disappeared.It now became obvious what was happening.The timing was out by the width of the key looking at the marks on the shaft,which could be about 15 degrees.Multiply it by 2 for crankshaft degrees.Think about the crank position sensor telling it when to inject and the other sensors disagreeing and thats the problem.So I made a slightly oversize key,cleaned up the shaft and gear and put it back together.Loctite on the nut,torqued up and a bit more.Thats not coming loose again!.Built it all back up,splutted on 1st turn,started on 2nd turn.Sorted.Building up, I reckon I know why it came loose.When changing a cambelt,(as mine had before I got it),its a bit of pain to get a socket on the crank nut so you can turn the engine over to line the marks up.Its a lot easier to put a socket on the cambelt drive pulley nut innit !.DON`T EVEN THINK OF IT.Take the sump-guard off and turn the crank clockwise only.Its no problem from underneath.And the ECU,I aint sure about that.Theres no way of knowing.Since this saga,I`ve found the problem with the shuddering gear box.I`ll let you know when it`s fixed.

Great news.

Yes you are right it's much easier to turn the camshaft pulley when changing the belt although I always do it from the crankshaft pulley because when you turn it from the camshaft you are seriously in danger of making the belt jump a tooth anyway because of the way the tension goes into the belt before the tensioner. And yes you should always turn it clockwise not anticlockwise as it's better to tighten the bolts up than loosen them.

Mind you on the 3.0, changing the belt is quite easy and to be honest if you make sure it is setup correct before taking off the belt you shouldn't need to manually line up the belts as they should stay where they are. It's certainly a lot easier than on the 2.4 which is a right pain.

Gload you got it fixed, pity about the ECU not being the problem after spending the money on it.

awww you guys, youre amazing.
You lost me on the second sentence..
