    Hi all,
    So.my discovery TD5 makes a horrible whining noise with the clutch depressed, researching this points to a noisy spigot bearing. My question is this:-

    I have changed a clutch on a 300tdi by jacking up 1 side of the car and "sliding" the gearbox back allowing access to change the clutch - is this possible with a TD5?

    How accessible is the spigot bearing - my plan is to change everything changeable while the gearbox is off.

    All advice greatly received!!

    Sure it's not just the thrust bearing?

    yes best with an engine crane with a chain slung through the open tunnel,spigot bush when fitted can be a tight fit on the shaft often need reaming out a little

    I'd like to think it's the thrust bearing, but it's far too noisy (my opinion) to be this, it's quite intermittent and fairly embarrassing in Morrison's car park!!

    James is "the man" on this forum for mechanicals especially, and top for gearboxes and other running gear.
    Surprised the idiots who make them can't make the spigot bushes the right size but maybe (out of left field this) they deliberately make them tight to compensate for wear to the tip of the input shaft, who knows? I sure as sh!t don't!
    Tempted to say "while you're in there, why not do the clutch, DMF, thrust bearing, the whole enchilada?". But if you're doing it yourself labour is cheap whereas parts ain't!;)

    What a tw@t I am, just reread your first post and noticed you're gonna change it all anyway, well they say great minds think alike, but in my case it's "fools seldom differ" not saying you're a fool, oops! (I'll shut up now!)

    hardly any wear on that end of an input ,its the same bush as fitted to the old 2 1/4 diesels,but hole in crank must be slightly smaller as when you fit the bush it can then become a tight fit on the input,you dont find that with the earlier engines

    Well that clarifies it. And so great you warned him else he could have fitted the bush then had to ream it in place or else extract the blamed thing, ream it then put it back in at which point it'd probly spin! And if you just pick it up and start reaming it, how do you know how much to ream it by?
    Bonkers!
    What cheapskates on what is not an expensive part.:rolleyes:

    I've been told I'm a fool for buying with problems in the first place!!

    I'd like to think of it more as a Labour of love......

    easy to fit, just tap in,but not one edge at a time you need something so you tap the whole bush in like you would a bearing race

    Not if you get summat off the price. I've done that in the price, you just need to be sure what it'll cost to ix.

    I suggest that you check or change the clutch pushrod while you're in there. The ball that fits into the socket in the clutch release fork can wear to the point where it pushes through the hole in the fork and then you can't disengage the clutch. It happened to me at about 200k miles. I put up with a noisy spigot bush for about 150,000 miles btw. I only changed it when the box came out for a clutch change.
