You can look in your Rotax manual to see what it is supposed to be. I would hook up an AC Voltmeter, connect one lead from your pickup coil output on your engine and the other to ground. If you are getting the specified voltage, you have a wire problem from there to your tach. Bob Spudis N701ZX CH701/912S do not archive In a message dated 7/27/2006 5:44:20 P.M.

There are two wires from the tach pickup coil. One of them should be grounded and the other goes to your tach input. You can disconnect both at the connector on your engine and connect your voltmeter to both leads to check the output while the engine is running. Also you can check the other side of the connector and see if the lead that is supposed to be grounded, really is. You might have a bad connection on the ground for the pickup coil. You can also connect an ohmmeter on the two pickup leads to see if there is an open condition on the pickup side( this is done while the engine is off!). My guess is that you have a ground or wiring problem, especially since you said it was erratic and the other tach didn't work. Not likely the pickup coil. In a message dated 7/27/2006 6:25:53 P.M.

According to the guy I talked with, it is the Rotax Ring Mount. ZAC has a new motor mount to attach it to the firewall. He said the ring mount retails for around $900.00 U.S. I didn't see any Rotax labels on the mount, but according to the guy I talked with, it came from Rotax.

Which ignition module is Left and which is right? In the drawings there is a reference to A and B modules. I am thinking that A is left and B is right, but I have thought before and been proven wrong. I don't know if it is critical, but I would like to know.

Epoxy paint properly applied would probably do as nice a job at the bearings for me, but plating seemed a bit risky. I haven't changed the thickness of my gear plates yet and we've lost a few to the plate thickness at the welds.

There is an update that says to use AS5 rivets on the firewall. The problem is that ZAC only sent 50 AS5 rivets and most of them go in other places. My question is where AS5 rivets needed on the firewall are and can I use A5 on most of the parts? I have no problem getting more stainless rivets if need be, I just want to do this right. Thanks. I have gotten a lot of useful information off this list in the past and enjoy it quit a lot.

My solution was to weld a triangular gusset to front and back of the strut to plate junction. It increases the welded area a lot and hopefully will prevent a problem from occuring. I am enclosing two shots of my fix. Hopefully the pix aren't too large for dialup users, but the detail may be helpful. The fix isn't hard but removing the gear assembly from the wings is a pain in the &$(&#*. Don't plan on doing it again any time soon.

Aluminum rivets will melt quickly in an engine compartment fire while the stainless rivets will withstand any temperature you are likely to get. The stainless rivets are also quite a bit stronger than similar sized aluminum rivets since they are steel. I guess a good rule of thumb is if the firewall is steel then you should use steel hardware and parts on it.
