Member Contributer boOZZIE Posted June 5, 2020 Member Contributer Share Posted June 5, 2020 After noticing some cct noise i think I have a problem with the rear cct. I have put a small flat head screwdriver in and tried rotating the plunger clockwise with barely any movement. I then tried c/clockwise with a little mment and back clockwise with about a corner turn. Is the cct shot or does it need some more movement to free it up? Front cct got about 3 full clockwise turns and moves freely Link to comment Share on other sites More sharing options...
Member Contributer Cogswell Posted June 5, 2020 Member Contributer Share Posted June 5, 2020 That seems odd. If it's stuck or jammed that could explain the malfunction (noise). Hard to say what to do with it, but I would be inclined to somehow remove it to at least inspect its function before relying on it. If it's done maybe 70k or more, it might be worth just replacing them pre-emptively. Let us know how it turns out. Link to comment Share on other sites More sharing options...
Member Contributer Grum Posted June 5, 2020 Member Contributer Share Posted June 5, 2020 That is strange! Turning the tensioner shaft clockwise should retract the tensioner shaft. At least it's the rear one acting strange, easy to replace. If you can't retract the plunger, be super careful in removing the CCT, you could easily catch the plunger cap against the engine casing and have the cap fall into the engine. Possible chance the internal plunger spring has broken. Throw it away and fit a brand new one. Link to comment Share on other sites More sharing options...

Thanks for your knowledgeable reply guys, yep I thought I mite need a new 1 after 55k klms I'll put a new 1 in and see what's up with the oldie. So you lock it in position with the "key" and its not suppose to stay in position with it out, right? I'm just thinking maybe give the key a turn?

I'm just thinking maybe give the key a turn? Yep. With the key inserted rotate fully clockwise to fully retract the plunger, push the key into the slots to lock it. Then unbolt and withdraw the CCT, and do it gently so the cap doesn't catch on the engine casing. Retracting the plunger minimises the chances of catching the cap on the engine casing! Have you got the Service Manual? You can download from this site if you haven't. Link to comment Share on other sites More sharing options...

You can easily screw the plunger with a small screwdriver but you still need to lock it from springing back to the extended state. Link to comment Share on other sites More sharing options...
Member Contributer boOZZIE Posted June 6, 2020 Author Member Contributer Share Posted June 6, 2020 So I was going to see if I could get some movement out of the rear cct plunger with the engine running. STOP DONT DO IT Engine oil does flow quite freely through this. Doh Link to comment Share on other sites More sharing options...

Suggest just evenly undo both bolts and remove the CCT as squarely as possible to its bolted down position and be conscious of the steel cap not catching on the engine casing. Fit a new item with a new steel gasket, job done. Unless the cap has obvious damage, just swap it over to your new CCT. Don't forget the end bolt and sealing washer or you'll be dripping oil again.

Member Contributer boOZZIE Posted June 6, 2020 Author Member Contributer Share Posted June 6, 2020 Haha, I wish a drip was all I got Ordered a new one so I'll need to wait a week or so for delivery Cheers Link to comment Share on other sites More sharing options...
Member Contributer boOZZIE Posted June 21, 2020 Author Member Contributer Share Posted June 21, 2020 So after ordering the cct lifter (5 June), H HQ had a ransomware attack which delayed my part order and then according to the H dealer that I ordered the part from the parcel has been lost. Part re-order delivery expected week of 22 June. In the meantime I took the cct off to inspect and wouldn't you know it, I have movement 🤬 So I put it back in a checked movement again and all good. The plunger screws in & out and no clatter or rattles while running. Anyways ill keep an ear out and I'll have a spare if need be Link to comment Share on other sites More sharing options...

Wonder if you had some form of crap in the plunger lead screw of the original CCT. Don't be concerned you have a new one on order, it will get used! Cheers.

Member Contributer boOZZIE Posted June 21, 2020 Author Member Contributer Share Posted June 21, 2020 Yeah not sure what was making it stick as it still wasn't moving after it spewed oil out when I turned it over and had cover screw off. Anyways I'll see how it holds up. Cheers Link to comment Share on other sites More sharing options...
