Crankshaft Pulley Removal
Posted: Fri Mar 08, 2024 8:57 am
I’m looking to change the cam belt on
my Honda engined 1991 416 Gti.
Although I’ve owned the car for 27 years I have always been able to find a reliable garage to do the repair.
Since moving to the South West I have struggled to find someone to do the repair.
It doesn’t help that I have brought some of the parts , good quality parts, one garage would do the repair but wants to buy the parts themselves.
I have been putting the job off for a couple of years ( lots of reasons) but now the cam belt is over 7 years old and I need to crack on with it.
The thing that concerns me most is I’ve heard tales of how hard it is to remove the crankshaft pulley bolt that’s torqued up to some incredible value.
The manuals tells you to lock the flywheel with a tool which you can no longer get.
But reading some of the technical articles on the forum it seems you can make a special tool to fit the crankshaft pulley to stop it rotating and then use a 3/4” SD 1000mm breaker bar to crack the bolt.
I intend to try to undo the crankshaft pulley bolt prior to actually starting the job , just to see if it is a problem (If access allows)
However it also seems that people have used impact wrenches to remove this bolt .
What are people’s experience of this?
I have seen videos of people locking the system by putting the car into gear and putting the brakes on hard to stop the crankshaft turning.
Do you have to do this with an impact driver?
As the car is an auto I wouldn’t be able to do this so wondering if this is an option I have .
Just wondering if the force of the impact driver is so instantaneous that the crankshaft doesn’t have time to turn.
Appreciate any comments based on peoples experience.
Many thanks
