Great looking project and a great looking work space you have [...]


Thanks for the kind words! Yes, the workspace is great, although a pain to keep clean ;-). It took me several iterations to get a workspace like this, but it is certainly a very nice place to be!

Yes, I will keep trying the welding, but I'm already sure that I will ask somebody else to do the actual restoration work. It's just not my kind of job. I like to do the mechanical stuff and refurbishing of old parts.

Got some goodies to continue the work:

 

* Top arm rebuild kit

* Copper rings for oil pressure relief valve cap

* Bottom arm to tie rod bolts

* Clutch slave cylinder repair kit

* Gaskets for clutch/brake master cylinders

* Braided hose for hard line to clutch slave cylinder

* New clutch master cylinder

* Blind bearing puller set (the one I had only contained a slide hammer to pull, but wasn't up to the job)

* Stack oil temp gauge (was not in stock when I ordered my other gauges)

Then I continued taking the front suspension apart:

After some fiddling, I got the suspension strut ball & cup out (I put the ball in the drill and forced it out while rotating, couldn't find another way...) and the rear bearing. The front one didn't come out using my "old" puller (it's only a few months old):

I tried heating the arm & pulling, I tried WD40, nothing worked...

But then I used my new puller, although there was not a lot of "meat" to put the legs on....

Used Meguiars Leather Cleaner & Leather Conditioner using several brushes and microfibre towels & put some correct bolts in place. After closer inspection it appears not to be leather but rather some rubber like stuff.

 

Maybe I keep it, maybe I'll have it recovered in leather, maybe I'll sell it and keep my leather Mountney steering wheel. What do you guys think?

Finally put my engine on a stand. Took some time to get all of the spacing right, but it now fits using the oil filter housing bolt holes and the alternator bracket bolt holes;

Then I continued the rebuild of the left hand driveshaft. I figured I would need to completely refurbish them now as opposed to just make them work, because otherwise I'd need to take them apart again for paint etc. As you might have read in my initial post, I first want to do a "dry build" to make sure all holes are in the right places and everything works and fits, before I take it apart to have the bodywork restored and painted and build everything up again. That means that while the bodywork is out for repairs and paint, it gives me time to refurbish all parts. Anyway, this is how it went;

Ooops! It's more than half a year ago since my last post... Time for an update. I must say I have not been doing a lot to my Mini, but the last few weeks, I found my motivation again and started working on it...

 

Finished one of the driveshafts:

Got a nice package from Minispares (the tool on the side is not from Minispares, it's a tool to remove the retaining pin from the gear linkage coupling):

This is a photo-heavy update which I will split up in multiple posts. Cracked on and got some results. Hope you like them.

Heater unit was looking sorry, so took it apart, cleaned it and replaced the matrix because I suspect the previous owner has used anti-leak stuff in the cooling system... Also replaced all of the foam and sprayed the flap. As the old heater matrix had some spacer brackets, I had to fabricate something to achieve the same and not have a rattling heater matrix in the heater unit. I used Innox FC-Foam, which is normally used in flight cases. Pretty expensive stuff, but it works great and it is easy to cut with a sharp knife. Of course, after the dry-build, I will address the rust on the control unit.

Then I mounted the left-hand hub. I had already partly refurbished this driveshaft, but I figured I'd do it the same way as the right-hand side, including spray painting the shaft (I know I swapped driveshaft sides by accident, will fix this later).

Then it was time to lower the rear subframe and get my nice goodies mounted. It was relatively easy to remove, probably because the previous owner already removed it as part of their "rebuild". I found some odd things though, like locknuts put on the wrong way round and metric bolts/nuts...

Behind the brake backplate, corrosion was so bad, I was able to break off a rather large chip by using an old screwdriver and hammer;

Do the nuts and bolts that hold on rear backplates go the other way? / the brake springs may rub on them else? :-)

Thanks, you have a very good point! I put them back the way they used to be, assuming it had never been taken apart, but apparently I was wrong. I will definitely fix this 👍.

The nuts and screw holding on my back plates had the nuts on the inside (within the drum) and I refittted them like that when I rebuilt them. 

 

I think the springs I had were handed, so they should fit without touching the end of the screws. Once I rebuilt them, there is more than enough clearance between the spring and the screw, so I'd just check the springs if I was you!

As long as the springs don't catch on the nuts or on the hub then they'll be fine.

 

However I think you have the shoes in the wrong orientation - the leading/trailing edges are wrong.

I checked the Haynes manual and there it appears the nuts should be on the outside. So in my case, they are the wrong way round.

Thanks for your thoughts. How can you see they are wrong? These new shoes are not very clearly sided, whereas the old ones were; you can tell by looking at the area that the friction material doesn't cover, which should be the leading side.
