Thermostat for b series rolls royce engines

Recommended Posts

Hello all

 

Just been quoted £88 for a b60 thermostat !!!:shocked:

 

That seems a tad high...... Anyone ever found a modern replacement ? If its the right size, with a suitable temp range and it opens enough to let the water through , wheres the problem ?

 

Any ideas ?

These are from my notes on part numbers either from parts catalogues & equivalents or types that I have found that were fitted in service.

 

Thermostat, Smiths (bellows type) FV145168, LV6/MT1/SM/X/30065/42 (also /36), RE21886, X30065

 

Thermostat, (wax type) 78 degrees, FV669056, LV6MT1/6620-99-813-0240, RE26275, C3508-150-78CPL14660

who quoted you that price?

 

Dont really want to shame the guilty , but another dealer offered me a quote that was half the £88.

 

I have now removed the thermostat, and tested it and it seems to work very well, so hopefully I won't need a replacement. I do appreciate that it is a nice piece of engineering though .... Heavy but nice !

 

Maybe the cheaper price was for a different type, or a modern equivalent but I just asked for the price for a B series thermostat and was not offered a choice, so I could only assume there was one option.

 

I run a business and one thing I know is that customers have long memories for good and bad experiences.. When I enquired with expensive dealer about his price , asking him if it was perhaps an error because the other dealer was only charging half the price I was told to "go and buy it off him then "

 

Maybe that should have been an opportunity for him to explain the difference in items available ( taking only 10 seconds) , instead of losing a customer (forever) in 10 seconds. :-D

 

Anyhow, I am going to investigate a cheaper option ... :-D

Hello,

 

Several years ago there were some posts on the Ferret Heaven Group about a Toyota stat being used on B Series engines. The 2 most useful were posted by Jim K, message no's 12088 and 12090 He owns a Stalwart and has done the conversion and offered pics and instructions. I would copy the post here but I would guess that breaks some sort of Forum etiquette. Regards, Bob

I have a Smiths bellows thermostat, it has the following part numbers stamped on it:

RE23713

FV147388

30065/42

72C162F

 

That one match out of four, I assumed it was for a B series.

Brian the first 3 all tie up, but I can't cross reference 72C162F. Its structure suggests it might be a RAF Vocabulary item. But I have the RAF B60 Mk 5 Schedule of Spare Parts that gives their vocab ref for the thermostat as 16B/7449.

 

However this equates to Rolls Royce part no UE3531 = Smiths Y.30065/40, so that all ties up. I have got the 1952 Humber parts list & that gives another variant 30065/32, although at that stage it didn't have a RE or FV allocation.

 

I can't see the significance of the suffix, I had thought it might be related to an opening temperature or something. RR list a few of them here although there is no indication to what particular applications they might apply.

I note in RR Service Bulletin No.25 that they wax type should be replaced every 2 years, but I idon't think I have ever seen a wax one.

 

BTW we are all familiar with RR part numbers prefixed by RE, but what is the significance of the less common UE prefix?

Hi Clive,

 

I have always understood that UE part numbers were for items specifically intended for civilian / commercial versions of the B Range. That is, any engine with a "0" after the Mk. number, ie. Mk.50.

Although there are some UE part numbers which also have FV numbers. Then there are UA numbers as well. I can see that RD seems to be the RR number for approved electrical items from CAV, Delco, Lucas etc

We got a thermostat from this mob in the USA a couple of years back:

Maybe you guys know more about them than I do. I can't recall the price at the time, but it was reasonable. Might be worth a follow up.

Banister's is one of the main dealers in the UK http://www.milweb.net/go/banister
