RobTR3 Posted July 20, 2017 Report Share Posted July 20, 2017 I want to remove the breather pipe from the engine block to give it a cleanout with petrol. I've inserted a long screwdriver up to the first 'bend' and extracted some oily black deposits so I think a general clean out is in order. However, I am not sure how the pipe is secured into the engine block as it seems pretty tight when I apply some sides pressure to the pipe end. There is no fixing bracket to the sump although the welded bracket on the pipe is there. As it is firmly fixed without this bracket it must be very tight in the engine block. Is the fitting a straight push in until secure and hence a 'lever' out job to remove? With the engine running I can feel the downdraught from the pipe end, so it is breathing/working. Perhaps I'd be wasting my time trying to get it off as it is not that accessible. What do members think? Rob Quote Link to post Share on other sites
Fireman049 Posted July 20, 2017 Report Share Posted July 20, 2017 Hi Rob ~ The breather pipe is a 'crush' fit into the block. If you twist it back and forth it will come away. My breather pipe was also blocked with 'crud'. The pipe is secured to the sump securing bolt. Tom. Quote Link to post Share on other sites
RobTR3 Posted July 20, 2017 Author Report Share Posted July 20, 2017 Thanks Tom, that's helpful. Probably, i'll give it a go. Rob Quote Link to post Share on other sites
j-eichert Posted July 21, 2017 Report Share Posted July 21, 2017 Rob: There is a short bracket welded to the pipe. Then you need an additional short piece of "bracket" (merely a short length of metal, two holes at the ends & twisted 80°) that connects/ fixes the pipe to the sump. Maybe this one is missing.... sorry found no good picture for that.... Regards, Johannes Quote Link to post Share on other sites
ijonsson Posted July 21, 2017 Report Share Posted July 21, 2017 (edited) Is this the clamp you meant? Maybe with some "aftermarket" extra holes, or a piece missing of the front straight leg? Edited July 21, 2017 by ijonsson Quote Link to post Share on other sites
Fireman049 Posted July 21, 2017 Report Share Posted July 21, 2017 Rob ~ Here's a photo. of the pipe. The 'twisted' bracket is in line with the flange of the sump. Tom. Quote Link to post Share on other sites
j-eichert Posted July 21, 2017 Report Share Posted July 21, 2017 (edited) #5: This may be a later version or some aftermarket part. The original (at least early TR3a) variant consist of a "flat" bracket + the first part welded to the pipe. See http://www.moss-europe.co.uk/shop-by-model/triumph/tr2-4a/engine/engines-components/external-engine-components.html and look at part 38/ 39. My "38" ist bend approx. 90° and the welded part at the pipe (part 39) ist vertikal, not horizontal as in the picture Maybe this pictures shows it a bit better....

stuart Posted July 21, 2017 Report Share Posted July 21, 2017 Is this the clamp you meant? Maybe with some "aftermarket" extra holes, or a piece missing of the front straight leg? That looks more like an exhaust bracket. Stuart. Quote Link to post Share on other sites

ijonsson Posted July 21, 2017 Report Share Posted July 21, 2017 That looks more like an exhaust bracket. Stuart. No, diameter is just as diam of breather pipe. But the breather pipe on my present engine is the welded type support. Quote Link to post Share on other sites
RobTR3 Posted July 21, 2017 Author Report Share Posted July 21, 2017 Thanks for all the replies. The welded bracket on the pipe itself is there, but the short straight piece to one of the sump bolts is missing. Even so the pipe is still firmly fixed in the engine block and I did not want to do any damage by pulling or twisting it to free it and clean it, Tom says it's a crush fit and will come out with a bit of twisting etc. So I'll probably give it a go. The short missing piece I can make up easily enough if I get the pipe out and it's a bit loose on refitting. Rob Quote Link to post Share on other sites
Fireman049 Posted July 21, 2017 Report Share Posted July 21, 2017 Hi Rob ~ I also had to fabricate the short metal stay. The pipe being a 'crush' fit should easily be removed. Like mine, you'll no doubt find the pipe blocked with thick gunge! Tom. Quote Link to post Share on other sites
