Hiya kids,

Would some kind person tell me the diameter of the drift i will have to get/make so that I can replace the old worn bushes and pins on Sherms project Mini.

I have the MiniSpares catalogue and it has special tools for this job on page 54, but how often are you going to need them???? hence, the question.

I've removed the hinges and got them bead blasted at work and am cleaning out all of the threads. Next job is the bushes and pins.

Hooroo

I have a standard set of five Sutton drifts in my toolbox, and the sizes required were in there. So I'm guessing it's a standard size and not some oddball freakshow drift.
Sorry I can't measure one at the moment cos I'm at work.

This was an accidental duplicate post. I have now substituted it with a random Wikipedia
article for your enjoyment.

The giant grouper (Epinephelus lanceolatus), shown here with a school of golden trevally, is the largest bony fish found in coral reefs, and the aquatic emblem of Queensland, Australia. The species can grow as large as 2.7 meters (9 ft) long, weighing up to 400 kg (880 lb). They are fairly common in shallow waters and feed on a variety of marine life, including small sharks and juvenile sea turtles.

Cheers Mick.

My other hassle is - this is a new job for me and I can't find any info. on "how to replace the pins and bushes.

I believe you have to knock the bush upwards to get them out but thats all I know. Can someone give me a few pointers please.

Cheers guys




Ah yes, the other thing I need to know is......Boot lid hinges, do you replace the bush/pin in these too in the same way???

I use the following tools to do them.... in the order as follows:

an old punch with a pretty blunt point
a 5/16" bolt with the thread ground off the first 1cm
a 1/4" bolt x 1.5" and nut

clean up the hinge so you can see which end of the existing pin is knurled, and knock it out from the other end with the punch - I think the knurled bit is at the top, so you bash it from the bottom

put the 5/16" bolt into the old push and bash it out

sit the new bush on your thumb and fill it with oil and then put your finger over the top of it - squeeze until the oil leeches out of the sides of the bush (they're porous and need to be impregnated with oil)

put the new bush over the 1/4" bolt and put the bolt through the inner part of the hinge, line it up perfectly and then do the nut up on the other side to press the bush into the hinge

then put the new pin in - takes a bit of bashing, and I usually grind and then file the daggy bit off the knurled end

works for me!

Excellent - take ten brownie points for your knowledge sharing.

Thanks for the assistance - I feel (almost) confident now that I'm not going to stuff things up.

Cheers

The knurled end of pin is always at the top. Pins are 1/4" (6.35mm) diameter.
Karcraft and most Mini places carry the pins and bushes, they are sold separate.

I take them off the car, and sit them in a bit of hardwood sleeper which has a shaped groove to hold the hinge.
I use a 1/4" or 6mm pin punch and BFH to drive the pin out towards top of hinge.
The centre part may or may not have a bush in it already. If yes, drive it out with a 5/16" pin punch.
If no, use a bench drill to drill the hole to 5/16". It must be drilled square.
I drill to 7.5mm first, then 5/16", and I oilstone the corner off the 5/16" drill so it cuts true size.
I use the bench vice to push the bushes in square.

NOTE- the new bronze bushes are 5/16" (7.92mm) outside diameter. If the hole is already worn bigger than this, this bush will not work. :cry:
Either find a another better hinge to fix, or get some bronze bushes made with 9.0mm OD and 5/16" ID.
:wink:

Thanks Kev. With any luck, I'll have this little job sorted in a few days. Your input is most welcome - as always.

My little girl's (Shermn on Ausmini) mini resto. has come to a bit of a standstill at the moment as she has been unwell - hopefully some more attention can be lavished soon. :)

Hooroo

I just bit the bullet and bought new hinges. $$$ yes, but then again, some of the threads in the holes of my hinges had worn out... and then the tap snapped off inside it as I was trying to re-thread the bolt hole... so yeeeaahhh...
