    I’m prepping a 2008 CRG Kalifornia frame to be powder coated.

    I’ve got a question about the engine stop block mount.  I’ve removed the mount and stop bolt, the there are still two threaded sleeves in the frame holes.  The frame has four distinct height positions for the mount, so it appears these sleeves should be removable to change position.  But I can’t seem to get them out.

    Any advice here before I break out the hammer?

    Pictures please!

    Most of the time you can get away by using masking tape in all holes before you send out your chassis.

    But it would really make it a lot easier if you could post pictures of your stuff, to be able to help and advice you better.

    Here’s some pictures to underline what I’m asking about.

    Those look like inserts/timeserts

    They’re usually pressed in, as you can see most likely they were pressed in at the factory, at the desired hight.

    I would totally cover the holes with masking tape, or find 2 bolts of the same pitch, screw them in, or better yet find a bolt with a wide head that will match the flat side of the thread flush, screw it in, tape the end that will stick out the other side and remove them when powder coating is finished, cut and trim with a brazor blade some of the burr, left over paint so that it won’t chip away, not to mention it will look neat.

    Hope that helps.

    I just had a frame done with the same fittings. The powder coater used rubber plugs through those threads to protect them from the powder – very much like plumbers plugs. Don’t forget to cover and/or plug the internal face for your steering column uni-ball bearing and c-clip groove.
