SH P6-28 Pro Spec with severely aggravating problem

lol, prefer a cigar and a brandy first. i'm a bit calmer then.

Too fancy for my taste....I'll take a beer and menthol! Yeah I'm a little redneck.
No hard feelings bud.
PigDog I'm pretty sure the new bearings will put your engine back to proper running order. let us know how it turns out.
Run it easy for the first tank to break in the bearings. I learned a lot about bearings on boca's site. I suggest everyone read through their site.

Yes thank you and the boca site is certainly an awesome source!!

I am thinking that I will order the ceramics from boca because the engine is in really good nick, the sleeve and piston are in very good condition and have no wear when compared to the new spare which my friend has.

I have to wait for the bearings to come over from USA to AUS so I may be waiting a week to 2 weeks but from what I have read and spoken to racers, I am certainly convinced that the ceramics would be beneficial over the standard metal bearings.

Thanks everyone for the tech support and asistance, and I will certainly keep you all posted as to the outcome of the new ceramic bearings!

Another quick question.

I know its the same as with the bigger motors (cars etc), The notch in the piston sleeve goes into the notch in the block, but which way does the dot on the piston go?

It is at one side and i can't visibly see any differences to justify one way or the other, but I'm certain that it is there for a reason, just as they are in the bigger stuff.


I ended up ordering the ceramics from Boca, because a mate had an order to make anyways so we saved on postage and ended up getting my two crank bearings (including conversion fees and postage) for less than they wanted for the one small bearing locally.

Now I have to wait VERY patiently for the carrier pigeon to arrive before I can reassemble and get out and driving my :buggy1: again.

Did you take the con-rod off the piston as well? Usually, there's a little hole near the lower bushing and I'm 99% sure that hole points towards the front of the engine so oil can get in it from the intake through the crank.

If you didn't take the con-rod off the piston, that's one way you may be able to tell.

Usually to avoid confusion, I mark the top of the piston with a permanent marker so I don't run into that problem.

Sometimes there's a cutout on the skirt of the piston to clear the crank on BDC.
