Flywheel bolts – Freed !

So .. the moment of truth .. after a couple of tentative attempts at removing the flywheel bolts which were stuck super super fast and hard I felt we were facing the inevitable sheared bolt and then engine out and weeks offline

Mike F .. my long standing engineering guru was practicing removing loctite secured bolts in his workshop and a mate of his popped by and said .. you don’t want to do that … you should use the tool ive just got !

Enter Darryl Morris owner of Morris marine and motors at la Collette St Helier .. with his awesome induction heater

We unwound the entire wire extension lead .. or it melts in a could gooey mess if you leave it wound up ! .. the show head was very precise and could easily be placed on a single flywheel bolt head.

The machine is set to 140′ C and touched onto the head and the button pressed …

20 seconds later we removed the probe and eased the 1/4″ socket Allen and lo and behold we had movement… gently and slowly we eased the first one out to check state of thread and washer

All looked fine … now realise the new bolts are shorter by around 6mm or so … we put the first NEW bolt in place with its new nordloc washer … it stiffened at about 75% in so we withdrew to check..

Looks like it would be wise to tap out the hole once each old bolt is removed..

All bolts slackened in about 10 mins !

Awesome machine .. thanks so much Mike AND Darryl !

Three cuts … 1, 2 amd 3 to cut finer and deeper in successive SLOW turns

An old bolt out … about 6mm longer than the new ones … also you can see the old Loctite on the end threads

it’s going to take a while to get the shaft holes cleaned properly … the hole in the back end of the crankshaft is about twice the depth of the bolt .. but getting the new ones in really tighten early because of the residue on the thread … going to tap gently just to clear half turns at a time of the thread
