Thanks Guys. I think it’s the britpart ones they have in stock so seems like these are OK to use.

OK. I'm half way there.
I've just ordered the Ashcroft output shaft. On the clutch - I'm going to order the LOF ExtremeSpec Clutch kit. Spoke to Luke and he says the pedal feel/weight is much like the OE install - just far stronger, longer wearing and with upgraded springs. But... they also offer this: https://lofclutches.com/shop/clutches/peda...-cylinder/ If the garage is changing the slave cylinder, then they'll have to bleed the clutch hydraulics - in which case changing the clutch master cylinder shouldn't add much labour time. Does anyone have any input on the Powermaster clutch master cylinder and return spring? I've never had much of an issue with clutch weight but for an extra £69, it might make sense to do this at the same time - I'll confess I have toyed with a slickshift - either from Syncro Gearboxes or from TMD and a lighter clutch would let me make better use of the gearbox (and may make it easier for my partner to drive too. The gearchange is a little notchy so a new selector (and taking the opportunity for another upgrade) may help in this regard. |

Have you noticed this warning about the master cylinder:
*Cannot be fitted in conjunction with the LOF POWER Slave cylinder* * Please do not fit with a brand new clutch until it is fully bedded in * There is something that I find worrying about a master cylinder which cannot be used with a new driven plate. I'd want to know why. |

ahh... I didn't see that, thank you. I'll call them and ask.
My understanding is that the PowerSlave cylinder is a R380/TD5-specific upgrade: there is a flowchart showing this here: https://lofclutches.com/wp-content/uploads...3.jpg.webp As far as I can read the PowerMaster can be used in addition to the OEM 2.2spec concenric slave cylinder, but I will call to ask as within a week of having this lot fitted I'll be setting off on the North Coast 500 run. |

I think that the master cylinder can be used with the TDCi concentric slave cylinder, yes, but I would like to know why it doesn't work properly with a new clutch. I have heard tales that if you do fit one with a new clutch, then you cannot reliably fully disengage the clutch. That to my mind is a bad thing and I personally would not fit one.

that makes sense to me. As I'm having a new clutch fitted - I won't go for it at this juncture. Like you, I'd be uncomfortable (now) knowing that every time I have the clutch changed that I'm going to have issues with the master cylinder.
Think I'll have the upgraded spring on its own though while I'm getting some bits. |

I have the power master and clutch spring installed. According to Luke of LOF, there is a "bedding in" period for the power master in which you have to drive it as much as possible. The clutch pedal will now sit proud and there will be a learning curve to drive your truck smoothly again especially if you are used to the weight of the standard clutch. It is this "bedding in" period which, according to them, will make it difficult to work with a new clutch since you will have to bed that in as well.
Clutch pedal is now nice and light. There are still times that I still step hard on it out of habit but I've more or less gotten the hang of the new, lighter feel of the pedal. |

If I understand this right, the "powermaster" is only a different master cylinder, in which case the concept of bedding it in is a nonsence. "Bedding in" a new clutch makes more sense, sinc ethe initial wear (until the rubbing surfaces are flat) will be quicker than from then on.
I would still be uneasy at fitting a master cylinder which apparently is incapable of fully disengaging a new clutch, it isn't right. I would welcome a more rational explanation if there is one. |

This is exactly the route I went. If you intend to "check the diff" then you may as well upgrade the cross pin to an Ashcroftt HD pin while you're there and replace the brass/copper thrust washers I recently had the transfer box off to rebuild and was pleased to see that the Ashcroft shaft is still A1 three years after fitting.

thanks Hank - how are you finding the clutch? No rattles or anything like that?

Well, that was the explanation I got 
In any case, while figuring stuff out for the power master, I did drive around with just the pedal spring and the standard clutch master cylinder, it still helps make the pedal lighter. So if the power master thing isn't your thing, the pedal spring should still help make things lighter. Cheaper too  |

I must be honest there is a rattle in neutral when off the clutch which hoes when the slightest of pressure is put on the clutch. Noticeable because I am aware of it but any normal person wouldn't. Apparently this has been rectified in the current version. By the way, over the years I have changed most driveline components to replicate what you are proposing... New uprated clutch New slave cylinder New output shaft One piece rear halfshafts Check/replace propshaft UJs. Check diff. The three biggest contributors to taking out my slop were output shaft, one piece shafts and diff planet gear thrust washers > 110 XS Double Cab |

Hank, I’m about to buy a new clutch, but think there might be some slack in the diff as well. How easy is it to replace the parts you mention and can it be done in-situ or does it have to be taken out?  Monsieur Le Grenadier
