I am coming to the end of a major service, TB, WP, VVIS screws and all coolant hoses.
Below is not “how to do”, others have covered that elsewhere but my observations on parts of the process.
Whilst I have hand tools, jacks, stands and the like, I do not have a lift and I don’t have air.
CRANK NUT
Last time I changed the TB and WB, as preparation, I took my car to a local HGV garage. I removed the OSR wheel and with the crank nut held got them to rattle it undone with a 3/4” drive air impact gun.
Since then I acquired an offset Impact Bar [Sealey part No VS786] and have used it elsewhere for crank nuts and differential pinion nuts.
I found the motto, ‘don’t use force, use a bigger hammer’ worked. Car lightly jacked up, wheel removed and the crank nut retained against the ground; there is enough space to have the impact bar almost horizontal. As a precaution against a bending load on the crank, I pushed a block of wood between the plate holding the socket against the chassis.
It looks agricultural but it worked.
