Re: Cont 470

Measure the stub shaft diameter and length to mounting face, slide a piece of same size pipe into it, long enough that the cover plate holds it in place. If no size pipe available, take solid aluminum dowel and have it machined.

Re: case pressure...

Well, most likely it doesn't have anything to do with case pressure, vs either too deep of the champher where oring seats under cylinder base, or the thru stud wasn't sealed correctly when case halves were assembled.

Re: 0540 newb

Good call, might just need a teardown, cleaning, blast the distributor blocks and check for cracks, and reassembly.

Re: 0540 newb

Remove the plug wire harness caps from mags and check for corrosion and or carbon tracing at insulators or from distributor block to case.

Re: Oil pump for Continental 0470 GPU needed. Does anyone have one or know where I can find one?

It is not likely pump, add a washer or 2 to pressure relief valve spring, if that doesn't change things when hot, bearings are worn out.

Re: Has anyone found a way to grease steering cables?

I've done the similar thing, clamp a hose over mounting threads long enough to clear stem, remove the dust boots first, elevate this end and put a funnel in end of hose, make sure you cant knock funnel out with cable stem full travel, fill funnel with atf or as above mmo, cycle cable in and out or u...

Re: O540 10:1 piston or leave it stock?

If fresh overhauled, no need to scuff anything, be sure rings stack into same bores they came from, they'll be fine. The sky Tec has a weak spot, fine for planes that don't do hot starts, I'd suggest a Norman clay setup. Also have the impulse coupler (s) and dog pins inspected for wear, leading caus...

Re: What MOTOR and HULL do I have?

Well, it's not a 125 gpu case and it's not a 125-D2 otherwise there would be a breather at right rear of case. It very well could be a 150, the hull is hard to tell, too many different styling ques.

Re: Step hull vs straight hull

It all depends on how they are designed, I know of light riveted step hulls that can go just as fast sideways as forward, sleds tend to crow hop if too much bend in transom kickup, it all really boils down to the builder.

Re: Step hull vs straight hull

Step hulls transfer to a plane faster due to less area in water to break free, a well designed step hull will run soely on the step at speed, with that chances of blow over is reduced but does happen, flat bottoms take more to get on plane.

Re: Ring Gear Replacement

Personally I just heat ring, once new ring on, evaluate pinion to ring backlash, if there is no shim between mount and case then you may have fine tooth mount on a coarse tooth setup, put fine tooth pinion and ring gear on it.
