ADR and PHP crank :)

[dmpus]

Just when I thought PHP is the better product, came across this thread. Good info. ADR cranks are POS based on personal experience. Looks like going back to DASA with 8mil crankworks crank.

Sounds like the issue with ADR cranks are the bearings? Has anyone discussed this with them? I guess it only matters because of rebuilds now.

Who are claiming the issues is with the ADR cranks itself and not another factor like water, compression or ignition?
@dmpus what happened to your ADR crank?

I had bearings go out on my ADR crank with about 30 hours. Probably closer to 15 hours.

Interesting.. my 10mm ADR suffered a bearing failure this season. I can't confirm, but I believe the engine had ~40 hours or less.

I've been running PHP motors for the last 5 seasons and the cranks have been bullet proof. Lots of guys around me running them as well, great longevity. Yet to see one fail. Some on their 4th season of what I would say above average run time.

I've never checked the runout on my PHP crank but I have a few seasons on mine now and it has been great. Runs amazingly smooth too.

Lower piston rod bearing on the rear cyl put a hole straight through 8mil stroker cases at 50h. All i have left of my engine is carbs, intake manifold and cylinders on a 2nd bore.
On the market for a new engine PHP, ET or whatever is out there. I like stroker extra boost on the bottom but i may try SS if it is that good (doubtful tho)

How many seasons did that crank have on it? (in whole years)
Are you 100% this didnt happen from hydrolocking or water intrussion that rusted the bearrings?

I’ve had a few adr cranks. 10mil in a tpe 1105 I had bought from skinnyman ran about 300 gallons before the rear bearing went out. I had a 10 mil adr in a Dasa I broke a piston in and a 16mil adr in my tpe 1200 I ran about 300 gallons through. The 16 mil needs a rebuild. Bearing cage started to come apart but I caught it before it did any real damage. So far my 1200 has been the most reliable motor I’ve ever had. No complaints

One season. Never sunk. I ride 99% surf so for sure it took some salt through it. Always rinsed at the local lake, always dried and kept with open hood. Always fogged after rides. It did sat for longer periods of time during summer months when surf is flat here so that could be the biggest contributor.

How do you think nicasil cylinders will hold up in the surf? Drinking salt cocktails is inevitable

Nicasil does not like water ingestion just like any other motor. But In most cases what ends up happening is the piston transfers aluminum on to the Nic and the actual bore is left un-harmed. This can easily be cleaned off if one knows what they are doing. Every winter I have sent my cylinder to TPE to have it cleaned and honed. The last time it was done Erik checked the bore with a bore gauge and it measured as good as brand new after 300 gallons.
Now this may be over kill for some but it lets me sleep at night.

Yeah thats sh$t if it went after only 1 season. I think seasons is more rough on a crank, than hours it self (unless you ride100+ hours every year) as its almost impossible to keep water out of the engine, and thereby bearrings.

From personal experince and seen from others, nikasil seems to be ok, if can somehow can keep water from spraying in your intake.
When you get water through your carbs, it will sand blast intake side of piston, due to nikasil being much harder than the alloy piston. Sleeved cylinders seems to wear more equal to sleeve/piston.

Usually I take apart engines after 50 hours to check pistons, cranck bearings, gaps and change pistons bearings. Every time cranck ends beat around 2/10 ( 0.2 mm).
