Hey there a long time ago I bought the 8.4 to 7.5 conversion kit from minispares. I never have got round to fitting it, but now with london to Brighton round the corner I am aiming to get it fitted this week. The only problem is I am currently working away from the car at the moment and won't be back untill tomorrow (by that time the machine mart no vat sale will be over). So I am wondering what tools i will need for the job incase I need to pop into machine mart for anything today. What size scanners fit on the bleed nipples etc? Basically what do I need!?!

Thanks for the help

copper grease on the back of the pads unless you want squeaky brakes 

 

set of spanners 

 

breaker bar for the hub nut + a massive socket i think its an 32mm but someone correct me.

 

appliers to remove split pin from hub and pads in calliper. 

 

bleed brakes - i used ezibleed, cheap and no mess instructions are very easy 

 

thats about it really

The hub nut should be either 1 5/16" or possibly 33 mm or 34 mm.

  it's 1 & 5/16" or 34mm.  Ideally you will take both as the car could have either size nut fitted.

 

  Torque wrench.

 

  Bleed nipples can be a variety of sizes, just take a selection of small imperial spanners.

 

  If you still have rubber brake hoses then a hose clamp will save you some trouble.  Or are you fitting new hoses?  That would be the best bet.

You'll need a proper big torque wrench, can't remember exactly the torque required for the hub nut but know its more than most 1/2" drive wrenches go to. Somebody may have one you could borrow if you're lucky.

Thanks for the help guys, Got everything all I need now is a big torque wrench! Anyone got one in the Rutland area I can borrow?

You need a torque wrench for the caliper bolts ( 40lbs), never needed a torque wrench for the hub nut. Remember to pre load the Hub nut instead.

what does pre loading the hub nut mean?

[jaydee]

Conical roller bearings have to be preloaded and well seated onto the CV joint.

This is very easy to do, but if you have never done wheel bearings before, at this point a torque wrench could help:

The easiest way to pre-load wheel bearings, is to get a big flat washer (like this one http://www.minispare...ols/TOOL21.aspx  ) and use this instead of the conical washer. Torque the hub nut, and keep spinning the cv in the hub by the drive flange during the process (tighten about 1/4 and spin the drive flange, tighten 1/8 and spin the drive flange and so on..).If you have little to none experience with the mini bearings, a torque wrench could help you to tighten the hub to the correct torque setting. Once youve done a couple of bearing you already know whether it is tight or not..

Once torqued dont fit the pin!

Have a cup of tea and leave the hub torqued for a quarter or half hour, spinning it round every now and then.

Undo the hub nut and replace the big flat washer with the proper conical washer (use a brand new one!).

Torque it up and fit the pin. (At this point is totally useless a torque wrench beacause you should have to set the hub at about 200n then tighten up to next hole which will result in torqueing up even to 360..) 

Job done.

Hi,

 

I dont mean to hijack this but the last 2 posts are well confusing. Why do you need to pre-load bearings? and Dilligaf - what did you mean by 'alternatively fit the bearings properly in the first place...........'- how?

 

I've done bearings on an old Renault 5 I had and it was very straight forward. I had imagined it would be the same on the mini - was I being naive?
