III. How to use the Flat Rate Time (F.R.T.)This F.R.T. (Flat Rate Time) is used to determine the standard labour time allowedfor replacement of parts covered by the warranty during the period the warranty isin effect. The F.R.T. for those parts which are not listed herein should bedetermined from the operation closely related to the replacement of that part.1. The F.R.T. is based on the following service conditions.a. Aliberal allowance is added to the net servicing time.b. Standard times specified are based on the condition that the necessaryservicing tools listed in the service manual (motorcycle) which describesthe HERO HONDA service policies are available close at hand and thework is performed by a mechanic with normal skill.c. Time required for inspection and operational test following the servicing isincluded in the F.R.T.2. Method of computingThe job times are listed in tenth of an hour to simplify computation.(Example) 0.3 = 18 minutes5.6 = 5 hours and 36 minutesCONVERSION CHARTHours Minutes Hours Minutes0.1 6 0.6 360.2 12 0.7 420.3 18 0.8 480.4 24 0.9 540.5 30 1.0 603. Computing the F.R.T.When several jobs are performed at the same time, make the calculation in thefollowing manner.a. Jobs of non duplicated natureThe F.R.T. for the job is obtained by totaling the F.R.T. for each part replaced.(Example) Replacement of head cover gasket and oil filter.SERVICE ITEM F.R.T.Packing, cylinder head cover 0.5Cartridge, oil filter 0.5The F.R.T. For the job is : 0.5+0.5=1.0b. Jobs of duplicated natureTake the F.R.T. For the last part to be replaced.(Example) Replacement of piston and cylinder head gasket.SERVICE ITEM F.R.T.Gasket comp., cylinder head 3.0Piston *5.0The F.R.T. for the job is : 5.0c. Jobs of partially related natureTotal up the F.R.T. For all of the parts replaced and then subtract the F.R.T. forthe duplicated operation (i.e., cylinder head gasket service).(Example) Replacement of valve and cylinder head.SERVICE ITEM F.R.T.Valve *3.0Head assy., cylinder *4.0Gasket comp., cylinder head *2.5The F.R.T. for the job is : (3.0+4.0)-2.5=4.5• The F.R.T. shown with (*) includes engine removal and installation.• The parts, having the same number of man-hour, are identified by a mark•" ", and classified under the title of their representative work.8
