If you are using the Warp 3 blade prop, all you can do is clamp it with the large inner squash plate bolts, and the outer most small 1/4 inch bolts as the plate will prevent you from using the inner set of 1/4 inch holes ( but call Warp first and verify this but I believe that is how your setup must be). Also note on the instructions the torque required for these bolts, as they are tightened to a much higher torque the we normally tighten things on the plane.

The 3/8" face plate provided by ZAC appears to have to be placed between the hub and the back plate for the spinner in order to provide clearance for the 1/4" bolts that bolt the hub to the 4" prop extension. However the diameter of the face plate (squash plate) is too large to allow insertion of the inside set of smaller bolts for that clamp the hub together. > > I thought that perhaps the inside set of 2 bolts (4 per prop blade) are not necessary because the clamping force of the lager bolts is sufficient. Or perhaps I got a face plate that was too large in diameter. You're correct, Mr Breit, I found the same issue and spoke with Warp Drive about this. They offered a solution, but I ended up turning the plate OD down to 5.437 which is just enough to get the inside bottom prop bolts to fit.

After about 4 months of in-activity in the basement, my 912 has developed a drip of coolant. It is coming from a small open hole in the bottom of the case directly under where the water pump is located. It is not coming from the case/housing interface (as I had hoped). That would be a relatively easy fix of replacing the gasket. I assume that this hole is there to let you know that the seal in the water pump has begun to fail rather, than filling the chamber and getting into the oil. Looking at the exploded view of the engine in the water pump area, this looks like major surgery with the back of the case being popped off to replace the seal. I intend to call Lockwood Monday to get their opinion, but I would like to hear from someone that has been there and if it is a fix that can be done without removing the motor from the aircraft. (actually, that last is irrelevant since I also discovered what I think is a crack in the motor mount today as well) This engine only has 220 hours on it. Could this have happened because I park it for several months in the winter??

The Hobbs on my Zodie HD clicked past the 20 mark this morning. I'm half way to the magic number 40 when I can finally get outta this 50 mile circle. All's going well, except the Jabiru 3300's CHT and oil temps are still hotter than I want to see. At 2750- 2900 RPM's my hottest cylinder runs about 335 degrees and the oil temp is about 230 degrees. Lower RPM's yield CHT's 0f 250-300 and oil temps of 180. I'd like to go to a larger oil cooler, the one that's in it is pretty puny. I called the local Jabiru dealer in Fresno and he emailed me a pic of his installation: http://www.lightflyers.com/oilcooler.jpg , a much heftier multi-core setup. I know a lot of you guys have gone down this road before, so I'm asking for suggestions on what and where to pick up the right oil cooler. I'm gonna hit a couple of the local race car suppliers tomorrow and see what they have, but if any of you have already done the research and have any thoughts, I'm all ears... errr, eyes. Thanks, Rick Pitcher ________________________________ Message 5 _____________________________________ Time: 08:00:46 PM PST US From: Gary Gower Subject: Re: Zenith-List: Rotax 912 coolant leak --> Zenith-List message posted by: Gary Gower All of us (Rotax owners) will be waiting for the Lockwood comment, here in our club there are several 912's with lots of hours and without problems, so I cant help in this. I dont think is because of the winter... all 912's use antifreeze... Good luck and keep us posted.

They make nice oil coolers and Summit racing sells them. No a bad price either..
