Here goes:

Got a new forged 4340 crank - EMPI - It's very very nice - counterweighted
Got 4 new forged 4340 I-beam ConRods - AA - very nice - balanced to within a gram!
Got new Pistons and Cylinders - AA - 94 mm stroker - also balanced.
Got a new special grind cam from Steve Bennett at Great Plains
All new bearings
New oil plungers
New oil cooler
new oil filter pump
new oil sump (no starvation)
new crank and cam gears

Man, what a load of shiny new parts!!! I have had fun sorting and weighing and just looking at them, and am ever so glad I made the decision to rebuild the engine.


I rebuilt the carb
Ignition is new
heads are new (10 hours?)
all new hardware, and hi strength studs...

I just got done drilling all the oil galley plugs out and tapping them, and fitting aluminum plugs in the case.

Now, we're off to the parts washer to wash all the new parts and the case and heads!!

Pics forthcoming.

I may be back to taxi runs in April if I get this thing together!!

A likely story. Now a picture would allay any doubt.

Hi Spencer

Wondering how the VW is coming along. Am still working toward a VW for my tractor and want to consider the re-drive made by Valley as I think this is the way to make the VW perform.

Would like to find more reports on the sucsess and number of hours using this re-drive, still hve concerns about the radial load on that front bearing and the crankshaft ?????

Have you heard any additional reports of this setup being used on other craft that have accumulated numerous hours of flight time???

I have not found any reports in any of the other aviation mags.

WHY: the following links use vw engines with redrives besides valley:http://www.airdromeairplanes.com/TorqueMasterEngine.html http://www.greatplainsas.com/. One of them including valley should have a customer or two they can put you in contact with.

Check out the Great Plains site - it has links to WWI replica airplanes that are using the redrive from Valley Engineering... Which is the same one Steve Bennett sells at GPAS.

The latest version is the type III, and it has an idler arm and two 40mm belts - and from all reports, it is very smooth.

The tension on the nose of the crank with the redrive is really no more than the tension with the alternator pulley...

The big deal with the redrive is that is should eliminate ALL prop loads from the crank and move them to the case, as the redrive unit is connected to the ledge of the case... The loads from the belts are going to be FAR FAR less than teh loads from a prop in direct drive and prop hub...

Anyway - there are lots of ways to skin a cat, but this redrive from Valley is light, and it has it's advantages.

Also, call Larry Smith at Valley Engineering, and he would be more than happy to tell you about some of his redrives.

He might also cut you a deal on a type I or Type II, as they are now obsolete in comparison with the type III, and he may have some stock left over...

The other redrive out there from the guy in Holden, MO, sure looks like the one from Valley Engineering, or a close duplicate... Hmmmm.

Hi Spencer

I did notice the new type 111 re-drive, it appears to be a poly-V type belt. Many, many moons ago a fellow by the name of Noel Becar from Tulsa, OK made a VW re-drive that was almost a carbon copy of this, he started out with a aluminum pully on the crankshaft, which soon wore the little v's and started to slip so he replaced it with a steel one and had no further trouble.

By the time I had read about it in EAA magazine and gotten interested in it and called him, I was to find out the he had died earlier and no one apparently picked up on the project. I think the one in the EAA article was on a Pazmany Pl-1 or Pl-4 anyway back then it seems that re-drives were not looked into that much, (what a shame since we could have been maybe 20 years ahead on development and use).

The bottom line is that according to the article it performed great.

Wonder what the advantages of the Poly-V are over the cog belt?

IF you look at the "cogs" on the one from Holden MO you will see quite a different pattern that the straight cogs we are used to. At one time I had the name and manuf. for the pulleys and belts but they would not sell for an "aircraft" use.

http://www.airframesunlimited.com/?gclid=CMPLle3g5pACFQ2lQAodz0_cZw has a neat looking redrive that mounts to a flat plate under a rotax engine. This is from the powered parachute world. The actual manuf. will sell these for $675 currently.http://believeaviation.com/ is the link to that site.
