Triumphrat

I'm reassembling a bike someone else took apart (carelessly), started to assemble with a big bore kit then left it. I have been putting it back together and have run into what should be a simple issue.
In the Triumph workshop manual, there is a nice picture of the lubrication system on page A4 showing the same oil hose that Tees to the rockers, goes to the RHS of the oil cooler. However on P14 it says it goes to the LHS, and so does the Haynes manual. Could someone take a look at their bike and tell me which is right please?

Also I have a feeling the PO did not put the cam followers in any particular way, and the book shows the oil passages have to point in a certain direction. If they are not all oriented correctly, is this a major problem? I hate to tear the top end down again. When I got the bike the barrel was on and I took it from there assuming everything was Ok.
Thanks
Stu

Stu,

Doesn't the service manual have instructions on how to fit the cam followers, AKA lifters or tappets? I looked at my 1972 manual and on page B20, Section 17, it shows hows the cam follower are to be correctly assembled. These steps must be followed or else you get cam melt down.

I'll look at my T150 in the next day or so and see how the oil cooler hoses are configured.

Hi Stu,

I don't know if it helps, but the attached files show how my Rocker Three is set-up?

Thanks for the pictures, they agree with the written instructions in the manual, their diagram is WRONG. This is not the first mistake I have found. Like lining up the cam followers so the"oil holes" are correctly positioned, when the T150 doesn't have oil holes etc. Beginning to think I'll use my commonsense and forget the manual. I read all kinds of stuff about lining up punchmarks on the conrods and nuts, none of which I could see, I just slapped on red Loctite and torqued them up.

Hi Stu, Not trying to put anyone down here but there is a triple site at "Triples online", these guys only deal with Triumph and BSA triples and their wisdom helped me with my T150T. The manuals I have are wrong in some parts, the Haynes one is the worst and I see you have come apon the same problem. I now have a manual on C.D. from the TR3OC and it's well worth the $50. These just aint the same beast as the twin and need extra care when reassembling getting it wrong will cost lots of cash.

This is my other one...absolutely bog standard right down to contact breakers and posidrive crankcase fasteners!

Not sure who TR30C is? Can you elaborate please. I agree $50 is a good buy.

I do use the Triples Online site, but I often get more useful help on here. There are a lot of people who like to spout of which they know little there IMHO.

Sorry if I'm late chiming in, but I'm new here!

WRT the oil lines: the return from the oil pump to the oil cooler runs on the left hand side of the top frame tube, and there is a tee to the rocker feed, just before it gets to the cooler. The thinking there was that the slight back pressure from the oil radiator would help the feed to the valve gear. Warmer or cooler oil to the rockers doesn't seem to make a difference; in fact, there's a persuasive argument that, in most conditions the oil cooler is redundant, and in fact, keeps the oil from reaching its optimum operating temperature. But that's another story...

The oil line returns from the cooler to the oil tank, along the right hand same of the top tube, and passes above the rocker feed from the LHS oil line.

WRT tappets: Best practice is to replace the tappets exactly where the came from. Failing that, you need to establish whether or not your particular Triple actually has an oil feed to the exhaust tappets. Early triples had a feed from each main bearing cap to its respective tappet guide block, This arrangement was deleted on later triples (72-on, I think...), allegedly to improve bottom end oil pressure; also, race experience had allegedly shown that nitriding cams was enough to keep wear to an acceptable level. Allegedly...

At any rate, if you have the block off, you can tell quite easily if you have the oil feed arrangement, as there will be a metal pipe running from either main bearing cap to front of the crankcase casting. If you don't have this arrangement, it doesn't matter which way 'round the tappets are fitted. If you do, then you can tell where the oil comes from by looking for the holes in the bores of the exhaust tappet guide blocks and fitting the tappets accordingly.

Hope this helps,

Costa
