Crankcase mating surface cleaning

Automotive paint supply stores usually have 3 grades of the sanding pads. Medium, Fine, Ultrafine.

You could also use a brass brush.
 
I had mine water blasted, engine cases, gb housing and inner cover, very pleased with the result.

Crankcase mating surface cleaning
 
I thought that I would just chip in regarding progress.
Basically machine progress is slow, but that was to be expected.
The ability to source a standard camshaft is also seeming to be a problem but I remain optimistic.
Diversing from the engine I have maybe a stupid but curious question regarding the two bolts in the picture on the face of the gearbox. Is or would it be possible to remove each one to replace the 'O' Ring's so long as the engine is removed and the gearbox is in-situ? Or..... is this a very bad bodge idea?

Should be fine. Keep outwards tension when removing and reinstalling bolts so you don't push in.
The shaft on the camplate and quadrant will keep things in place while you pick out the orings and replace them.

I don't know if parts could move inside when unscrewing???But the next time you overhaul the trans, have the case machined to receive oil seals instead of o-ring. Then you will never see a seepage there again. Yeah!:p
 
They look very impressive but unfortunately there is nobody near me willing to do the work. While searching online I found plenty of companys who manufacture the machines though.
Great business opportunity for sure
Really Surprised you cant find anyone locally doing this, as the finished achieved in unbelievable
 
The "O" rings work well enough, and if the ones you have are original they should be retired.

The potential for damaging the the teeth of the quadrant and the cam plate is high, beware. When you apply torque to the quadrant bolt it can be supported, to some degree by holding the shifter. When you apply torque to the cam plate bolt the force bears on the teeth linking the quadrant and the cam plate. I know this when making mistake 2078 and broke a tooth on the cam plate gear many years ago; I think I'm up to mistake 3865 by now.

I'd advise you to live with the weep(s) until you are ready to overhaul the g/b, at which time proper oil seals can be installed. I'm still a believer on the "O" rings, and if you choose to go that way you can enhance their service life by selecting polished washers with the smooth side up against the "O" ring; you can also polish what you have.

when you go to reinstall the two pieces the quadrant goes in first and can be supported or held to take the proper torque. When you go to reinstall the cam plate use a large pin wrench fitted securely to the cam plate, do not try and pass torque using the quadrant at any stage.

Also, be sure to install the sleeve gear before the cam plate/quadrant, or you'll get a second lesson...

Best.
 
That sounds good for me and becomes the most logical road to go.
Many thanks for the input from all.
