Finger Follower - Design Revisions 2000-2005

[justinbaker]

Photographed 14th December 2005 - Noted the visual design changes. comments on this would be appreciated. I am off to measure these up and produce the engineering model for them.








The casting on the old item is a far better quality than the new, you can see how porus the material is in the machined 14mm dia bore finish, the supprise came from the oilway feed to the cam lobe being inconsistent. The holes do manage to penetrate, but are certainly "underdrilled" on some.

On measuring up the item, the oil feed has been drilled at a shallower angle to the 2000 model. This certainly would change the direction of the oil spray to the cam lobe.

If anyone wants the model (Inventor 10), or binary DXF I can email it.
Its a close as I can get with the measuring equipment I have.

Cheers Chris,

It is part of the casting for sure, it seems to be used to "start" the drill into the component, so I thought it best be shown.
I have just had my orders, to go and be sociable with my other half - oh well!!!

The manufacturer, this may not be TVR engineering are testing them for hardness. The batch I had fortunately shows this.

The box and the followers were on the desk together - It had to be done!!!

Here's an idea to lighten the valve train a little



Feel free to use the idea,
I have the model I can DXF if anyone needs it.
