Drivetrain Install The bell housing was mated to the engine after confirming the two alignment pins were in place. The thin brass shim made a couple of years ago was used to assure proper alignment. The transmission shaft splines were greased with the material that came with the clutch...

Bell Housing, Part II 3. Unlike Porsche or BMW, anything Jaguar needs to be double checked for proper alignment. One of the springs that holds the throw out bearing to the clutch fork rubbed slightly against the bell housing. Some time was spent gently filing a bit of material from the bell...

Bell Housing, Part I Multiple issues had to be resolved with the American Powertrain bell housing. 1. The clutch fork rides on a 0.50” rod. Unfortunately, the inside diameter of the bronze bearings installed in the bell housing were significantly undersized. Further complicating the issue...

Clutch Assembly, Part IV The flywheel has two pins in addition to the ten bolts. The two pins were put in the lathe and “polished” with 600 grit paper to assure there were no defects that would interfere with their installation. They are about .010 oversized. They were driven home with a...

The Tilton should simplify set up.

The Carbon Cub has been nearing completion. Ryan came and helped with the weights and balances measurements and the fuel flow, critical to final completion and inspection by the FAA. He then started up the engine and taxied a bit. Hope to have it officially signed off and fully completed in a...

Clutch Assembly, Part III. More than two years ago, before progress was interrupted by construction of an airplane, a couple of posts discussed the hardware needed to complete the drivetrain and dialing in the bell housing. Now we are back to the Jag. First, we will address the flywheel and...

You win!

Visited Bill Terry at his Jaguar engine shop this past week. Notice anything unusual about this engine?

I just ordered a few needed parts to complete assembly of the drive train from three different suppliers. It will be interesting to see if there are supply chain problems.

Doug Moving our D across the ramp at the airport this past week - Ryan steering and me pushing - the steering was light and required little effort. That would be close to finished weight with the drive train in place and the passenger compartment full of parts. Despite the weight of the...

The saga resumes

Good idea Doug!

Here is some information from Ryan: First, the operating angles on the end of the drive shaft need to be within 1 degree, meaning the output on the transmission and the input on the differential need to be parrallel. Setting the transmission cockeyed is not good. Needs to be parrallel to the...

Doug: my Jag is still at the hanger as the airplane is still in my garage. As soon as I can get access I will give you the height dimension. There are some defined parameters for the degree of offset that is deemed permissible and going beyond can lead to premature wear and other issues...

Using the filter as a visual size reference, and noting the bracket protruded further away from the engine, I question whether that would fit. Need precise measurement of total depth.

Doug: Consider adding additiional washers below the engine mount on the right side, shift the right side mount downward, and the left side upward. that will keep the engine level but move it to the left. The clearance is really tight around the oil filter and this solution worked for me...

Randy, you have a sharp eye. Indeed I goofed. it is the calipers that have that different offset.

Doug: Can you identify specifically which caliper was provided with your kit? My solution was using a different Wilwood caliper that was narrower. Details are on a prior post. Only needed 1/8" spacer to complete the revision. I would not want to solve the problem with thicker spacers. that...

We hung the engine this past weekend. Plan is to move the Cub to the hanger and bring the Jag from the hanger in the next couple of weeks. Gems and word of wisdom? Not sure you're looking in the right place.
