I believe sintered bronze bushes should be soaked in oil before fitting and then not need any other lubrication, yes? What about plain solid bronze bushes? Is it good practice to put these together with a little molybdenum disulphide grease inside the bush? Or are there better options - dry lubes etc??

Thanks again.

Sintered bushes are made from compressed particles (compressed under high force & temperature so that they fuse together) and then immersed in a lubricant while under vacuum. The vacuum is released and the bush is impregnated throughout.
Machining can close up some of the pores in the material, no lubrication should be needed.

Remember that the bush only comes into play while the clutch pedal is depressed, don't 'ride' the clutch and the bush sees less wear.....

Leo you can get away with either a bronze or brass bush but I would drill some 1/16th or 1/8th holes through the wall of it and work grease into them so that it has a bit of grease reservoir. By just slathering grease on the shaft means most of it will get squeezed out and may end up on your clutch surfaces, which you don't want. I made up a brass spigot bush for my vehicle about ten years ago and used a graphite based grease, it is just starting to occasionally squeal a bit now.
However sintered bronze is the choice.


Cheers, Mick.

[QUOTE=mick88;2392333]There are bushes available for the conversion and although they do the job there are better options. (listed as C18B $20 each. in Four Wheel Drives catalogue.)
With the Holden conversion the spigot shaft only just reaches the (standard length) bush, so only about 1/3 of the shaft runs in it. If you have access to a lathe these are the options. One option is to knock up a longer bush out of sintered bronze. The other is to make a steel bush that is a press fit into the centre of the Holden flywheel that will then take a standard Land Rover spigot bush (1.062" OD x .875" ID x 1" Long ).
Hope this helps.


Sorry I had the OD wrong on the above bush measurements.
I measured one up today.
Below are the dimensions for an extended bush if you want to machine one up. Excuse the "blend" of both metric and imperial measurements. It's just that I did the lengths in metric but stuck with imperial diameters as the standard sizes were.
Hope this helps.


Cheers, Mick.
