IMS bearing bolt fix
As a work around for the broken bolt.
in the photo of the broken bolt , where the zero end of the ruler is, cut through the bolt face it off on a lathe drill a hole right through the centre of the stepped remaining flange. buy a suitable hi tensile ( allen) bolt, push it through the drilled hole to replace the previous cut off bolt (same dia). tack weld the new bolt head to the flange for security (this is the end which goes inside the hollow IMS .) use sealer to replace O ring. result much stronger fool proof assy.
PS Double bearing NSK W5204 20x47x23.8 if you can find one.
otherwise .. NSK 5204 20x47x20.6 (readily available) add 3mm spacer (plain washer)
Remove bearing seals to allow oil to enter.
