OST-070: 7AGE for an N2 Levin

[oldeskewltoy]

So... While this is going into an N2 replica, it is being fitted with timing covers to protect the timing belt, and to keep the cam seal retainers*. This requires some fabrication, as there never was a 7AGE, so the timing covers don't readily fit. Additionally, an idler is being added to the long side to eliminate belt slap.

* - not many realize that the rear timing cover is also used to keep the cam seals firmly in the head

Essentially this is a 2 part job - part one, build the foundational parts(rear cover), part two - make a filler panel.



So the rear cover is cut so that it can be lengthened, in this case it was also the area that was needing clearance for the idler.



Note that the "clocking" of the bottom section has changed slightly... this is do to fitting this to a 7A block, as well as keeping the middle timing cover lower exhaust side mount correctly positioned.

This type of work is easier done when using the block and head, while a jig could be made, this is easier.... but if a "production" version were to be made, a jig would likely be better.


So this is what needs to be done to build a 7AG rear timing cover....




with all the mods performed...... (sans refinishing)





and side by side.....




more to come.....
