SS water return pipe and drive shaft bolts


Recommended Posts

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.

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 ……….

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.

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.

Regards,

Waldi

Ah I was looking at Revingtons but the number I quoted does look more like your original

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.

Regards,

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.

Thanks,

Waldi

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?

Hi Hans,

yes, (ja),  I ordered another one from a different supplier; there are 2 types, same diameter, but at different bend angles.

Waldi
