Removing Chain Tensioner Covers.

[SchnellSchweitz]

Hi again...

I'm tyring to remove the chain tensioner covers, but not having any luck. I believe I have removed all the nuts? Photos below.

Any ideas on how to separate the covers from the case without damaging the seams? Do people glue these covers on?

Thanks.

You will need to remove the bolt from the oil feed line that went to the tensioner.

Otherwise, just put a thin flat head screw driver in the side and twist lightly to not hurt the surface area. They just stick over time.

I see the bolts in the picture so I mentioned it.

Tap on the gasket ridge along the seam with a dull flat headed screw driver.

Be careful not to mar the sealing surface on the cover or the chain box.

Take an old kitchen knife that is sort of dull and tap it into the gasket seam along a top edge.
Try it in the lump right above one of the studs on the top side. The knife gets thicker as it goes into the gasket and should spread it apart.. someone may have used loctite 574 on the gasket so it's really glued on.

Thank you very much for the GREAT help!

I applied them all... including inserting the blade on one side of the seam and then back and forth until they finally came free. And no marring!

The weekend ends on a positive note!!!

Err, I was going to say do NOT put anything in the gasket seam.

To flatten the chainboxes all the studs have to be removed and then a surface plate with abrasive has to be used. Much easier to tap with a plastic mallet until it comes loose.

Good luck!

I tapped wood shims with A hammer to free my covers which had only been on A few months. The O-ring (on the tensioner) really holds them on. Next time I will use composite shims to avoid picking wood out of my housing!
