Engine Mount Drawings

Does anyone have a drawing of the engine mount for BC series (short or long )?

Re: Engine Mount Drawings

The Harer STC comes with the drawing for the long mount.

Anyone use the short mount on a C85-12 and got an approval?

Steve, it's been done quite a lot in the past...it's one of the options on the Gilberti (later Harer) STC.

There's some 337 & STC data on the Taylorcraft Foundation Technical Resources page.

This and this show two pages of installing a C85-8.

Hope this helps.

I put an O-200 on a short mount, it moved the engine foreward about 5/8" and you will need to modify the baffling to make it work. Tim

I saw a C85-12 installed on the short mount with a B&C starter and a wind driven generator. There was a slight dish in the firewall. Looked like a nice installation without having to add that 4" plug to the cowling and still have an electrical system.

Tim...
There is a work-around for this. The difference in dimension is due to the rubber Lord Bushings used on the O-200A are approx 3/4 or 5/8 inch thicker than the original rubber cone bushings. I addressed this problem for the L-2 STC by using 8 machined bushing cups that convert the O-200-A so that it uses the same original rubber cone bushings as used on A-65. The end result is that the O-200 is approx 1/8 to 1/4 inch forward of the original A-65. This is much less or no impact to the baffle and cowling fit. I have the drawings and installation I will sell with a DER approval for $50. You will have to machine your own bushings and submit on a 337. Hint... you can find the parts from a guy selling them on E-bay, if you don't want to machine them.
