Now we talk about the cam chain tensioner.

Afternoon KR,

So I've started to hear a chattering noise, and after running over my valves they're perfectly happy. I'm pretty certain this is the Cam Chain Tensioner. Done a bit of searching and about to order everything up.
Pre-98, of course.

As far as I can tell I'll be needing 15, 14, and 16-3. What are 16-1 and 16-2 and should I order those as well? Anything else I am missing?
She's got 33km and a bad history of PO care, what are things I should inspect on the assembly to see if it needs replacing altogether?

For procedure, just clear the way, unbolt the 19mm, unbolt the two bolts holding the assembly in, remove old spring and gasket. Push the adjuser in fully (using the button?) and bolt the assembly back in. Put the new spring in and the gasket on the 19mm and use a torque wrench to put the 19mm back?

The manuals are down and my copy was corrupted, anyone happen to know the 19mm toruqe offhand? IIRC the two bolts holding the assembly on are 10ft-lbs.

I'll do a small pictorial writeup on this when all's said and done.

you need 12 and 16 or 16-1 or 16.2 or 16.3, all the 16's point to the same gasket.

[Purplehaze]

12 is the whole assembly, yes? Is it not prudent to just replace the spring after resetting the tensioner?

[92xjunker]

Yes, there is supposed to be away to lock the spring back during install, total pain. So, yes, install the spring after setting the body.

But I wouldn't be needing 12 (the whole assembly, as I understand) if I have 16 (gasket), 14 (gasket), and 15 (the spring)? After resetting the body and bolting the two bolts back in I'll just insert the spring and the 19mm and then turn the engine and hear a few clicks?

Push the tensioner rod in with a dowel to preset it, then install the spring and rotate the engine.

Ah I see. With any luck I'll be able to tackle this well.

Anyone know of any common issues to look for on the tensioner body itself?

[92xjunker]

Watch your knuckles and bereak the spring but loose before removing the body.

I have heard of and had the tensioner break when torquing the 19mm nut down to spec, take it easy on the torque. I went with 20 ft/lbs IIRC AFTER with the new tensioner.

Same thing happened to this guy:

Definitely watch the knuckles when loosening. Bashed mine pretty good the 1st time I replaced the spring.

Willdo guys, thanks for the heads up. I'll be carefully tightening to 19 ft-lbs of torque as well - definitely not interested in that business.
