PHONE: 636 7064
Geddes Automotive Auckland change cambelts on cars & vans. Replacement cambelt broken cambelt & timing chain service.
CAMBELTS SNAP WITHOUT WARNING. CHANGE CAMBELT TO AVOID COSTLY REPAIRS.
Most manufacturers recommend a cambelt change every 80,000 to 100,000 kilometres or 3 to 5 years, whichever comes first. Some models of Subaru recommend a cambelt change every 48 months.
Check your owner´s manual for the change cambelt recommended period. Refer to the photo showing stripped cambelt teeth. The rubber cambelts perish with age and break; you don´t want your engines cambelt broken.
Book a cambelt service at our Onehunga Auckland workshop before it´s too late.
The cars cambelt can strip teeth or jump teeth without warning and when you are a long way from home. You then need to get home and get your car to a garage for replacement cambelt repairs. This operation (towing & travel) alone can cost more than the cost to replace the cambelt.
Geddes offer a FREE CARS CAMBELT INSPECTION to see if you have a label of some sort and tell tale signs to confirm if the cambelts likely been changed. If in doubt, it is cheaper to pay
the small price for the cambelt change before the engines cambelt is broken.
During a cambelt replacement we can inspect the cam and crank oil seals, the bearings and tensioners, and the water pump. An inspection will identify a problem if starting. A seized or partly seized bearing can cause the engine cambelt to overheat, stretch, perish & break, or it can flick the cambelt off the sprockets.
WHAT DOES AN ENGINE CAMBELT DO?
A cambelt is a continuous belt with ribbed teeth (refer to the photographs) as the starter motor turns the crank shaft the cam belt pulls on the cam or cams sprockets and turns them. The cam sprocket is located at the end of the cam or cams. The ribs on the engines cambelt fit into the slots of the cam and crank sprockets.
The cams have lobes, as the cam turns the lobes push the inlet & exhaust valves into the head to open and close in time with the crankshaft.
This allows fuel & air mixture into the head chambers which fires (explodes) and the burnt mixture is forced out of the head and out the exhaust. Most older engines had timing chains. Some manufacturers use either system on different engines.
TIMING CHAINS WEAR & BREAK, TIMING CHAINS STRETCH & JUMP TEETH.
Timing chains require good lubrication or the tensioner guides wear out and/or the chain wears and stretches and the timing chain can jump the timing gear sprocket. It is extremely important that the engine oil is changed regularly to avoid oil way blockage and premature timing chain and guide damage.
We recommend engine oil and filter should be changed every 10,000 k´s. We can do this at our Onehunga Auckland workshop.
IF ENGINE TIMING JUMPS A TIMING SPROCKET TOOTH OR TEETH. ENGINE CAMBELT BROKEN!
The engine is very likely to be damaged if the engine is an interference type. If
the engine cambelt is broken or the cambelt or chain jump teeth and the engine continues to revolve, then a piston (or pistons) can come up the bore and hit a valve. At best this may bend 1 valve.
