Fitting Back FIP Splined Coupling
« on: March 14, 2021, 12:00:48 »
Please kindly help me make sure I understand this correct, here is a quote form ja17:

".... I prefer to slide the splined sleeve onto the shaft in the engine no reference needed here. ..."

Does it mean that the place with empty space in the inner ring inside the splined coupling does not need to align with anything? Also: it seems also that it does not matter which way it goes on each shaft - there is no front and back of the splined coupling, is it correct?

I know the TDC+20 topic, I know the three marks alignment topic, no issue there. I was just not sure about the splined coupling and the above was the reference I found while doing my homework.

As I have the steering box out, I pulled FIP out as well to seal the bottom plate as it was leaking oil. The gasket that goes there is a separate interesting story as well, but I will write about it separately once I receive it from Bosch.

Just for fun I am attaching a picture of the main rack adjuster seen through its orifice.

The blank tooth on the IP drive gear should align with the slash-mark on the IP housing prior to assembly with the engine set to 20 ATDC. for the pagoda engine. The end of the IP drive shaft also has a slash mark which was most likely an assembly reference during assembly of the IP at the factory.

Thank you this is clear!

The splined coupling - we fit whichever way, correct? No marks to observe there?

Yes the splined coupling can fit any which way.

Thank you very much!

I will now just wait for the seal from Bosch, and I am ready to put FIP back in.
