I know you can modify a standard timing cover to take a duplex set, but other than DNS, does anyone make a timing cover that's specifically designed to clear duplex timing chains?

[Icey]

DSN/Retrosport make one that's compatible with both simplex and duplex.

And front plate.

Way easier to mod what you have and it ain't hard to do.

Isn't it literally just hammering the dimple out so its flat?

I'm pretty sure you don't need the front plate, but yes, I agree that to mod a later one is easy enough.

 

It's what I do.

Yeap, but also taking some care so as to not distort the gasket face nor the seal location, though I think you'd be going hard to damage these.

I thought the tensioner bump meant there was a hole in the wrong place?

I always thought you needed to use matched A or A+ front plates.

Nah. I need to modify the Pre-tensioner types to use them with a Tensioner (drill one hole), but not the other way around.

 

Also, with the 'dimple' that needs bashing out, not all tensioner type cover have that dimple, so can go straight on.

Do you know if anyone still supplies those new (original or remanufactured)?

And if not, any advice on how to identify them?

[nicklouse]

they are the old A series ones. not '"new".

[Cooperman]

I just took a small hammer to do the modification

It took me all of 2 minutes to do.

I doubt you'd find a new one, but I'm sure they come up on ebay often enough. They look like this;-

 

 

another option, as I mentioned before, is that there are some late timing chain covers that just fit right on, no modifications needed at all,

eg;-
