Waldi Posted June 22, 2017 Report Share Posted June 22, 2017 I ordered a SS water return pipe with the connection for a temperature sensor, as a replacement for my carbon steel one from a UK-vendor. I notice one bend has a completely different angle, so contacted the vendor. The vendor response is: "In the many years we have been selling 158417SST we have never had any complaints. I have checked all our stock and they are the same as the one we supplier you. So I am doubtful that there are any problems with this part". My question: can this pipe still be installed on my 1970 CP-TR6, or will it not fit? See picture below from my old and the new pipe. Drive shaft bolts: Also, from the same vendor, I ordered a set of bolts for the driveshaft, I thought these have a special , slightly bigger shank diameter to achieve a minimal cearance (think I read it on this forum, but could not find it). The bolts supplied actually had a smaller shank diameter than my old 3/8"UNF bolts: 9,37 versus 9,43 mm. The vendor response on this item is: "you wil find it wil be ok" My question: Is 9,37 mm still within the required tolerance for these special bolts? Thanks for your help.

Graham Posted June 22, 2017 Report Share Posted June 22, 2017 Hi Waldi I've had a quick look at the supplier in question and see they also stock 145398SST this appears to have a profile more like the old one in for photos, looks like there are 2 types of pipe one for US spec carb cars and one for all other types ? have a look see what you think. No idea why one should be so much more expensive than the other though ………. Quote Link to post Share on other sites
Motorsport Mickey Posted June 22, 2017 Report Share Posted June 22, 2017 Hi Waldi, I think this is what you want "The plain shank length of 107960 is greater than the equivalent pound shop grade item. It is also a controlled diameter" The number is a part number at Moss I believe where the bolts are available to order, information supplied by Peter W on a previous post.

Waldi Posted June 22, 2017 Author Report Share Posted June 22, 2017 Hi Graham, thanks; you probaby looked at an other vendor's website, some part numbers are used by several vendors, I notice. To avoid confusion: mine came from James Paddock, and since they have ony this one (with or withput the adaptor connection), I thought there was ony one type.

Mick Richards Mick, thanks, that was the previous post I recall; I looked up the tolerances per specification SAE J429: for standard UNF hex bolts shanks is: 0,369" to 0,375", which equals 9,37 to 9,53 mm. So it appears the supplied bolts just meets the lower limit of this standard specification, but like Peter has indicated, these bolts should be thicker per a dedicated specification. Does anybody know the required diameter for these bolts (Peter maybe)? Maybe it is not critical,but I have ordered them to make sure the correct bolts were installed, standard bolts I have plenty.

Waldi Good morning, Can anyone advise if the cooling pipe with the bigger bend (angle) will fit my 1970 CP car? My engine is out and part-dismantled, so i cannot trial-fit.

aardvark Posted June 24, 2017 Report Share Posted June 24, 2017 Hello Waldi. My pipe definitely more resembles the larger bend variant of the two you have and mine is 1970cp too. Cheers Dave Quote Link to post Share on other sites
Waldi Posted June 24, 2017 Author Report Share Posted June 24, 2017 Hi Dave, Thank you, I will keep it and see how it fits. Regards, Waldi Quote Link to post Share on other sites

Waldi Hi Waldi, is your problem solved whith this TR^water return pipe? I had the same problem. Moss is now looking for the good one i hope.. gr Hans Quote Link to post Share on other sites
iani Posted January 14, 2020 Report Share Posted January 14, 2020 Is the water pipe shape not dictated by the radiator type? Early cars have the bottom hose stub some inches in from the edge, later cars have the stub at the edge, presumably the longer SS pipe is to reach the latter? Quote Link to post Share on other sites
Waldi Posted January 14, 2020 Author Report Share Posted January 14, 2020 Hi Hans, yes, (ja), I ordered another one from a different supplier; there are 2 types, same diameter, but at different bend angles. Regards, Waldi Quote Link to post Share on other sites
