The piston slap will give a slight tapping tap-ping aound t a distinct hnock. As a rule a tap is not dangerous, but it i nd (rates looseness, and should, therefore, there-fore, be looked to. Where there are gears there will fll-waya fll-waya be a certain amount of a humming or growling- noise. Thus in an origins, a ktowI wil usuiilly come, from the half-time, half-time, runs no to or gencnttor rlrive penVs as at T. When It does not corne from a gear it will come from some irregular shaped pa rt such njs n pear, ejialn, fan. or pump blade nibbing; or to parts having" hav-ing" been romrhened because of lack of lubricating and by runbine, or to worn or dry roller or ball-bearing's. Thus a growl may come from the timing pears; from a chain V rubbing against its housing; hous-ing; fan rubbing" against radiator or engine: en-gine: pump blade rubbing or to lack of lubrication of any moving pnrt or ball or roller bearings. As lack 'if lubrication is liable to br tho causer the reason for a growl should be found as quicklv as possible pos-sible V.'ith the exception of a slirpine fan belt, a squeak is an indication that some parts are rubbing without lubrlca t ion. While it may come from any of the parts for whirh a luhricatinp svatom is furnished, fur-nished, it is usually due to sonio part. beniso of wear or Itv beinc bent, opting opt-ing In contact with another part which it Is not Hupposed to touch.
