Rev Counter Generator





Adaptor that screws into cam.






Plastic dog that fits into adaptor





If its just the plastic dog you need to replace remove circlip & fish it out with a screwdriver & push in a new one & refit circlip.

 

Excuse my building this post in bit's & pieces while finding pics.

 

Hi Glenn,

didn't notice that your answer was in 2 reply's .
I will try to pry the dog out whit a screwdriver as you suggested

Sorry we posted over one another. See my post above. You need to use circlip pliers or just a screwdriver if circlip actually fitted has no holes.

No Churchill tool I know of. Someone might have a better suggestion on circlip removal.

 

Glenn
Thanks again.

Greetings

Working at the back of the engine with a mirror can be a pain. My car's circlip in that location has holes for circlip pliers.

 

Churchill tool 18G 1004 works well with the 90 deg. points inserted--but any circlip tools with 90 deg will work.

 

Thanks,
I'm going to crawl on the engine with a mirror and hope to see a circlip with holes. ;-)

 

Presume that is no help with the older standard Jaguar Circlip with straight ends & no holes? I've never seen any tool for those darn things.

But will work with this type circlip with holes as fitted to my engine? As will most 90 deg inner/internal circlip pliers.

 

On a related note, is the tongued drive supposed to slide in and out? Mine will "snap" back into the generator housing if I push it in. It spins freely and does not feel any different than if I pull it back out and spin it. Its almost as if there is some sort of detent that allows it to be in one of two positions; in or out.
Thanks!!

 

you have found the problem: the "tongued drive" is not supposed to retract back into the generator. If it does, it disengages from it camshaft drive. I had to have my tach generator replaced last year for this very common issue.

 

SOV11,
There is a circlip to hold the the tongued drive, zie picture.

 

This is how the drive dog is secured so it's probably the original one.

 

Yes that is the original type. Hope you can prise it out with a screwdriver or similar.

This is the replacement:

 

Thanks,
already in the basket at SNG with new seal for the generator and the drive dog.

 

Great! Good luck with reassembly.
