Triumph TR6 - TR6 Timing Chain Redo

Hi All

New here, but I've been a TR owner for over 20 yrs now.

I'm ready to change out my timing chain on my 1974 TR6 and would like to know from the wise sages what I can look forward to. I've pretty much have done all my own wrenching over the years, so I'm not timid about tearing into it; just would like to know what to expect. What else should I do while in there. My Haynes manual seems kind of vague. Also considering doing thrust washers and connecting rod bearings while the car's in the air.

Did I see somewhere here that there's an electronic version of the Bentley manual available? I've used one for my Volvos and have found them much more in depth than the Haynes...

Thanks,

Jeff,
Welcome to the BBS. Send me your snail mail adddress and I'll forward copies of our cd's which include an electronic copy of the Bentley shop manual as well as many of the supply manuals that will be of great value to you with exploded diagrams. Email me at dbaker04 AT aol DOT com. fix the obvious and that's a ZERO not an Oh.

The CD is well worth the wait for the post, but if you are in a rush to download the manual, have a look at http://www.vitessesteve.co.uk/Servicemanuals.htm - he seems to have most Triumph manuals scanned and available for download. For backup purposes, and only for those who have paid for the manual, I presume.

Hi John

Welcome.

How many miles on the engine? Why are you doing it?

It sounds like you are going to do the timing chain in situ. You will want to take out the rad. You may have some challenges pulling off the harmonic balancer with the steering rack there. There is a cross piece that will have to come off and you may have to lift the engine up to clear things. I attach a before picture of mine showing the obstructions (with the body removed)

Replace the timing chain cover oil seal while at it.

If you are thinking of doing the connecting rod bearings you might as well go for the gusto and pull the engine and do the crankshaft journals and all oil seals, gaskets.

Thanks for the responses,guys!

Michael: I'm pushing 190K (a 100K of which are mine! I now have a permanent smile from driving all that
driving). As far as timing chain, I'm starting to hear a engine rattle at idle. Not sure if I'm ready to pull engine, though at 190k it certainly wouldn't hurt:) I've done some lower end work years ago with engine in car and thought I'd go same route again this time. Your image didn't appear to load. How much work to raise engine to clear things? I always have the conundrum of not wanting to lose a driving season (so short here in the Northeast), but I do enjoy working on something so elegantly simple!

I have resized the picture and reloaded. Hopefully this will work.

Can't say for sure if the noise you hear is the timing chain or maybe the tensioner inside the timing chain cover or even something else.

Fairly easy to raise the engine. Take a jack underneath (position jack as not to dent oil pan or use an engine lifter from above), undo the front engine mounts and lift. Although I will admit I have never tried to do the timing chain in situ. I have lifted the engine to get the V belt on. So I am assumiing you can get the balancer off by doing this.

At 190K I would suggest a full bearing replacement if you are going to do the effort. This assumes it has never been done.

I certainly understand the short driving season. We suffer the same in Ontario. The full engine job is best left to the winter months.
