Service Magazine SEPD0457, Article 2, Page 1, February 8, 1999; "Acceptable Welding And Drilling Locations On ROPS Cab".
Disregard the above referenced article and see Service Magazine SEPD0465, Article 7, Page 4 with the same title.
--------------- END SUPPLEMENT ---------------
Drilling and welding on the ROPS cab should be avoided whenever possible. However, if necessary, the following article depicts acceptable locations so as to not alter the ROPS Certification.
The maximum allowable diameter for any hole drilled into a ROPS cab is 6.4 mm (.25 in). Drilling should only be through the first layer of metal on the roof of the cab.
Use the existing mounting bosses inside the cab whenever possible, attaching plates to them and drilling into the plates.
See the following illustrations and dimensions for acceptable drilling and welding locations.
Roof of cab. Only drill or weld inside marked area, a minimum of 381 mm (15 in) from edge on all sides.
Only drill or weld inside marked area. On low cab, boxed area is 305 mm (12 in) to 610 mm (24 in ) below the headliner. On high cab, boxed area is 457 mm (18 in) to 864 mm (34 in) below the headliner. This allows for a 305 mm (12 in) high boxed acceptable area for both low cabs and high cabs.
Only drill or weld inside marked area, remaining 25 mm (1 in) from seams and rear edge.
