I got the 7.5:1 pistons from jt540. They are out of o-290d2, part # 69841. Was happy with them. Justin has a lot of parts for the 435s.

Do they have reliefs cut in the tops for valve clearance? Could be pistons from a go435 or vo435

I have same carb on my o-435. Runs good. My motor is a apart and a buddy has been running it on his go-480 with no issues...

10-4, Justin I'll call you tommorow. Didn't want to bother you tonight.

Thank you twister. I guess I am after a set of those (8) I will check with guy I get my parts from and if he doesn't have any I'll be back here looking for a set. If anybody can't get me a set of 8 please message me.

Can anyone tell me what the bore diameter in my case should be for my crank main bearings? I can't find that spec in the overhaul manual and something is going on... trying to re assemble my motor and I don't think these are the right bearings. Either my case was bored oversize or these are the wron...

I had Don George do mine.

The ring sets for 290/435 chrome cylinders are right around 200 bucks a hole!

i changed a few of the short ones on mine out and was able to get them at local ace hardware. the longer one you might want to try Justin ficken (jt540) or gary barber (Outlawaircraftengines)

I use seachoice #12101, good for 25amps @ 12vdc.

look up your motor. the size is usually listed or called out for the orings. once you know the size you can order it anywhere. McMaster, miller bearing, central hydraulic...

If it's an automotive starter call advance auto parts on Dixon and ask for Richard. He's pretty good with identifying starters that are brought in. See if he's workin and take it by there. i took one in and set it on counter an he brought 3 different ones out that would work without going to the com...

Why not just run high compression pistons

I saw this also. It is a good looking motor. Where he get the 13:1 Pistons? Use the 11 or 12:1 from angle valve cylinder in the str8 valve?

im wondering the same thing, if have crank polished and comes out .003" under do I need M03 or P03 crank bearings? All I see is standard and M03 on airpower website when I look up AEL11021...

lookin for cam from turbo charged helicopter motor. would cam from tvo-540 work?

i still have ring sets for chrome cylinders and yes you can use them 7.3 compression ratio pistons in them for a nice bump with out any mods. its when you go to the high compression 8.7 pistons you have to mill them down any idea what the 7.3:1 pistons would make In the str8 valve cylinders? never ...

you can use the 20 series bendix mags with these motors. im sure GMAC76 could tell you which would and wouldn't work and could get you set up with a pair.

the go-435 pistons are for angle valve cylinder, will make more than 7.3:1 compression ratio in the straight valve cylinders. wont clear the valves without milling them down either. look for the pistons from o290-d2, part number 69841. they make 7.5:1 in the str8 valve cylinders. put them in mine an...

I run carter 4-6 psi pump on mine with no issues.

Airtech will have what you need. Chances are you could find a match at advance auto parts depending on how good/familiar the person at te counter is with starters. My lycoming uses and erly 80s starter. It's direct drive and the 1.3kw turns it over just fine. Take the old one in there and they can m...

Orlando is about an hour from Melbourne, home to Hamant Airboats which has the largest airboat retail store there is. Alumitech is in Orlando, Diamondback and Panther both are in cocoa about hour away.
