who can tell me what's the different between R51/3 and R50 or R60 crankshaft.
thanks.

wu do RV hydraulic leg and forklift cylinders etc.

1,spray the white paint at first.
2,use PVC tape to paste the lines, i will chose 2mm and 5mm.
3,spray the finish paint.
4,remove the PVC tapes in 10 minutes before dried.

The paint process is more difficult, especially for the white line. http://www.vintagebmw.org/v7/sites/default/files/img_5491.jpg.thumb_.jpg http://www.vintagebmw.org/v7/sites/default/files/img_5516.jpg.thumb_.jpg http://www.vintagebmw.org/v7/sites/default/files/img_5498.jpg.thumb_.jpg http://www.vi...
