Hi all -
Not a 40 question but someone on here might have the know how or 'know a man that can' (or woman!)..
I've got a Maserati 3200GT motor in for works that has a knackered thrust bearing on the crank rear. Basically they have poor oiling as standard on the manual cars and the thrust bearings are prone to failure. This has happened on this motor and the crank now has a surface that has a ridge on it where the bearing failed, spun and wore the crank badly (0.034").
According to Maserati, the cranks cannot be reground and NO replacement bearings or shells are available other than 'std'..
SO, looking at a new crank really BUT someone has suggested it might be possible to metal-spray the surface, presumably building it up and then re-machine it to standard size and still be possibly cheaper than a replacement crank.
Anyone have experience of such processes or have had similar work undertaken? Can anyone reccommend a vendor?
