cp25616 Posted July 1 Report Posted July 1 No Peter, TR5 hoses were plain black. TR250, US 1969 TR6's and RoW spec 1969 TR6's wore black and gold hoses. TR6's from and incliuding the 1970 models were green. Alan G Quote
RogerH Posted July 1 Report Posted July 1 Can the black/gold 'Bumble Bee' hoses stll be sourced? Roger Quote
Z320 Posted July 2 Report Posted July 2 At Gernany we have „Golden snake“ quality water hoses (real rubber with textile, not PVC) from „Continental“. This is why „bumble bee“ hoses anywhere else than on houses and garden make me wonder. Don‘t feel impressed about my statement Quote

Peter V W Posted July 2 Report Posted July 2 David, Alan is correct, black hoses on TR5. So I’ve had a look at my old original top hose, stored for many years and attach a photo. Peter Quote

roy53 Posted July 2 Report Posted July 2 i think the only hose that had a yellow stripe on a 5 was the servo hose. Roy Quote
saffrontr Posted July 2 Report Posted July 2 Roy, the TR5 press release pack images and the TR5 brochure show the servo hose as the only hose with a yellow stripe. Attached for info is a factory image of one of the press car engine bays, this shows the yellow stripe on the hose (in black & white). For those interested it is negative number 71947 taken on the 27th September 1967. Some of the other details in the image might be of interest to those concours car owners. Derek Quote

Derek Interesting to see the PRV inline on the tank return from the metering unit and also that a PCV is also fitted in the same place as it was on my TR250 when I bought it and that it has an oil cooler fitted too.

Stuart. Maybe I'm misreading your comment, but didn't your 250 have the PCV mounted to the intake manifold between the carbs? Quote
Z320 Posted July 3 Report Posted July 3 (edited) Interesting to see the PCV on both photos IMO don’t work. On the first photo it is not fitted on the inlet manifold and if it is fitted to any vacuum the seperated oil can’t flow back (upwards) to the rocker cover. On the second photo it not only sucks vapors from the engine but also fresh air from under the bonnet. This should reduce the ability to seperate oil. Ciao, Marco Edited July 3 by Z320 Quote
dblenk Posted July 3 Author Report Posted July 3 Mine is a feb 69 registered 5 and my fuel pump has always been at the back and the pcv was the plastic one fitted to the rocker cover probably like the TR6 Quote

This is how it was originally fitted (First picture) it didnt really do anything more than dump engine condensate down the front of the engine, obviously not how Triumph had them fitted originally and then after I had rebuilt all the linkages and generally sorted all the engine out I fitted it as per the second photo and it worked really well there.

Z320 Posted July 4 Report Posted July 4 Hi Stuart, where is the lower hose connected to, please? Ciao, Marco Quote

Stuart. Clever. PCV tipping downwards in line between engine and inlet manifold and that is ‘T’d at the manifold with a non return valve to the servo. Good reinterpretation. Quote
Z320 Posted July 4 Report Posted July 4 Ah, now I see now, thank you for pointing on that, that works! Quote

RAHTR4 Posted July 4 Report Posted July 4 Reading this topic struck a chord because I had seen a reference to Gold and Black hoses amongst the collection of Standard Triumph Engineering Change Sheets I have. The Engineering Change Sheet found is labelled DEC 9087 and has two dates 30-6-67 and 10-8-67 the latter being on the cusp of production commencing, which Bill Piggott tells us happened on 29th August 1967. Description of Change Introduction of gold & black striped hoses in place of plain black. Production Instructions Class III Introduce as soon as available in car sets for all markets. Use up stocks of existing black hoses on markets other than U.S.A. PART No. Actual Details Affected PAGE No. TR4A – SUPT. 200 (WASP) 120331 Flex Conn. 3 off 1987 145640 Rad. Hose – Top 1 off 2141 145397 Rad. Hose – Bottom 1 off 2151 133309 Rad. Hose – Bottom 1 off 2151 622300 Heater Hose 1 off 3226 633353 Heater Hose 1 off 3226 REPLACED BY 148992 Flex Conn. 3 off 1987 148996 Rad. Hose – Top 1 off 2141 148993 Rad. Hose – Bottom 1 off 2151 148995 Rad. Hose – Bottom 1 off 2151 622158 Heater Hose 1 off 3226 622141 Heater Hose 1 off 3326 PE.156 – ENGINE UNIT – SUPT. 28 123495 Hose – Pump to Manifold 1 off 305 148474 Hose – Manifold to Return Pipe 1 off 305 (Heater condition) 133636 Hose – Manifold to Return Pipe 1 off 305 (No Heater condition) REPLACED BY 149439 Hose – Pump to Manifold 1 off 305 148994 Hose – Manifold to Return Pipe 1 off 305 (Heater Condition) Hose Manifold to Return Pipe 1 off 305 (No Heater Condition) This document demonstrates that this was a very late change, issued on 10-8-67 with the instruction for the gold and black hoses to be introduced into production as soon as the hoses were available. Production started just 19 days later, therefore with insufficient time to produce the gold and black hoses it has been confirmed that the first cars were fitted with black hoses. Does anyone know how long it actually took to obtain stocks of the gold and black hoses to enable them to be introduced in the TR5..? From the comment in the Production Instructions, it is very apparent that Triumph placed great importance on the market in the U.S.A. Regards, Richard Quote
