- What is an acceptable amount of slack in the TR3B (TCF) timing chain? With all the slack on the tensioner side I can measure 25mm of play. Is this OK? Thanks, Bill; ** triumphs@autox.team.net ** Arch

- how are you measuring the slack? there is a spring at the side that tensions it, but not until you put the timing cover on. Frank What is an acceptable amount of slack in the TR3B (TCF) timing chain?

- Measuring horizontally at the center bolt with the tensioner removed. There is very little side play, I don't know about any rattle noise as I have never driven this engine although it seems very sou

- Bill - I know this is in the manual somewhere -- but couldn't find it just now. But my notes from the last time I did this say "per manual, slack of < 0.4" is acceptable". What's a mm? Geo On Mon, Ja

- mm+Millimeter, about 1 inch, so more than double your noted amount. Guess I'll buy a new chain. TRF lists three different qualities of timing chains: 1. AE brand $19.95 2. Replica $9.95 3. Renold $48

- Bill - Yeah, I really knew what mm meant -- I was just shocked (shocked, I say) to see that unit of measure used on a TR3 post. I agree that an inch sounds like too much slack. What you might also th

- The timing chain on my early TR3A began rattling very noisily. When I replaced it, I went with the Renold brand. I can't say if it's better than the others, though reports suggested it was far superi

- I've heard chains and gears wear together. With an inch of slack, I'd make sure the gear teeth have enough depth left to do their job. The gears on my tr2 were shallow and quite sharp. I bit the bull

- Sorry, I forgot to mention that I did renew all sprockets, tensioners, bolts, etc. when I renewed the timing chain. Incidentally, I have never heard a timing chain get as loud as mine did in a very s

- When I pulled my TR3 engine apart, I found that the timing chain tensioner was gone completely and that the timing chain had a removable link that was missing in one side (towards the block). The pin

- Good thought, I tried to lift the chain off the sprocket and it moved less than 1/8"(that would be about 3.175mm, Geo) so I think the sprocket is OK, but I will take a closer look at it tomorrow. Thx

- Seems high to me, but that's not the way I was taught to judge timing chain condition. Remove the chain from the sprockets and try to flex it sideways in your fingers. If it will flex more than 1/4"

- I think that your standard timing chain from our main British suppliers are around $15 and an improved quality chain is around $45. Either choice is a no-brainer if you are that far into a motor. Jus
