WE EMPHASIZE THE IMPORTANCE OF CORRECT TENSIONING OF
A TIMING BELT TO ENSURE TROUBLE FREE SERVICE. FOR YOUR GUIDANCE THE FOLLOWING POINTS ARE NOTED IN ADDITION TO THE
||Do NOT crimp or bend a belt
through a radius less than that of the crankshaft drive pulley. Do NOT turn belt inside out.
||As a general rule fit camshaft drive belts to a "COLD" engine. This is to ensure the correct belt tension throughout all engine operating conditions.
||Remove spark plugs/diesel injectors to ease rotation of pulleys.
||Satisfy yourself that the new belts tooth form/tooth pitch/number
of teeth/belt width etc is correct for vehicle.
||Check drive wear pattern on all pulleys to ensure new belt will
run centrally about. Correct misalignments as necessary.
||Check pulley teeth valleys for dirt/oil contamination. Clean
with wooden scrape. Do NOT use cleaning solvents or metal scrapes.
||Correct any oil or water leaks that could contaminate belt.
||Check all auxiliary drives i.e. balance shafts/oil/water pumps/tensioners
for axial wear or tightness. Correct as necessary.
||For obvious reasons it is recommended that vehicles with tensioner
& separate idler pulleys be replaced as a set.
||Do NOT lever or force belts
||Fit any printed arrows in direction of rotation.
||Time and tension as per manufacturers workshop manual. Ensure
any timing tools are then removed.
||Turn engine over once by rotating crankshaft pulley manually,
(do NOT turn engine by any other pulley). Re-check timing marks and belt tension.
Do NOT turn the engine backwards as this could cause the timing to jump.
||Refit guards/spark plugs or injectors and run engine on test
for 20 to 30 minutes.
||Allow engine to go "COLD" and check for
oil or water leaks, RE-CHECK BELT TENSION.
||After 500 miles check for oil or water leaks, RE-CHECK BELT TENSION, again on a "COLD" engine.
||Do NOT tow start belt driven
||Do NOT use rapid gear changes
to brake vehicle.
NOTE! FORD 1400 & 1600 CVH. engines must
be fitted with the modified 57mm dia
tensioner roller (ULTRA-PART No. UT21). Old style tensioner rollers measure only 47mm diameter.
ALL FORD 1800 DIESEL engines must be fitted with steel idler pulley. ULTRA-PART No. Ui24
Or Ui64 which are also available in TIMING BELT KIT FORM: TBK18 Upto 1996 & TBK19 1997- ON.
Incorrect Timing Belt Tensioning Is The
Biggest Cause Of Timing Belt Failures.
We Thus Emphasize That Items 14 & 15 Are Vital In Addressing
"BELT SETTLE IN" During Initial Running Periods.
