Hamish Posted July 5, 2021 Report Share Posted July 5, 2021 (edited) After saturdays fun at Shelsely I was checking the car over last nigh and the fan belt was loose Medium story cut short. I have found the top (narrow belt converted) pulley wobbly and further investigation that the “woodruff” key worn BUT it really doesn’t look like a key but just a raise part of the shaft. Did they ever make shafts originally or repo with the key as part of the shaft as I can’t see that there is anything to be replaced. which is a pity as the pulley is fine as is the pump. just this worn key woodruff or casting into shaft. I’m racing again Sunday hence the urgency Edited July 5, 2021 by Hamish Bl@@dy auto correct Quote Link to post Share on other sites
RobH Posted July 5, 2021 Report Share Posted July 5, 2021 That must be a separate key Hamish but the surface of the key and of the shaft is so damaged you can't see the join. Keys are a very tight fit and often need persuasion to remove. Looking at the surface of the shaft, that seems very pitted and gouged so you will never seat the pulley properly IMHO. I think the whole thing needs to be replaced. Quote Link to post Share on other sites

james christie Posted July 5, 2021 Report Share Posted July 5, 2021 +2 I believe this is a fairly regular occurrence on some of the repro pumps and one of the reasons I include a spare in the boot when travelling a bit further afar than usual A word of encouragement, it can be changed without removing the apron - but maybe you knew that already! james Quote Link to post Share on other sites

Kiwifrog Posted July 5, 2021 Report Share Posted July 5, 2021 I have run a slightly modified fergerson tractor waterpump (sleve to fit the pulley) in my 3a for almost 10 years as I didnt like the look of the repros at the time. cheers Alan Quote Link to post Share on other sites
Andy303 Posted July 5, 2021 Report Share Posted July 5, 2021 I highly recommend the Racetorations billet pump. It comes with the narrow pulley already fitted. Not cheap but far better made than the repro stuff. Fit and forget. Quote Link to post Share on other sites

Hamish Posted July 5, 2021 Author Report Share Posted July 5, 2021 Well thanks to this forum :- RogerH sometimes mentioning the TRSHOP. Who have come up trumps with a replacement pulley ( that they have split a narrow belt kit for me ) Ep services for the pump off the shelf ( mine to be returned) and some hopefully prompt carriers I should be good for this weekend fingers crossed. thank you everyone H Quote Link to post Share on other sites
RogerH Posted July 5, 2021 Report Share Posted July 5, 2021 Hi Folks, as Hamish has found, The TRSHOP are often prepared t break their kits to get at a single item. As this thread is about pumps here is an interesting pint that may help somebody one day. In 2018 my water pump gave up the ghost at Gaydon. Another TR driver helped me out (Tim Hunt) as he had a spare pump in his boot. I could take my pump off but could not remove the pulley - and the spare pump needed my pulley. aaarrrggghhhhh I got about 10 miles down the M40 before the pump became scrap. When i got home and sorted the pump I made myself a slim line pulley removing tool - ust like an umberelli it will never be needed but is in the boot anyway.

Z320 Posted July 5, 2021 Report Share Posted July 5, 2021 (edited) What about a spare pump with pulley already fixed there? Like two umbrellas? Edited July 5, 2021 by Z320 Quote Link to post Share on other sites

rcreweread Posted July 5, 2021 Report Share Posted July 5, 2021 Guys - if you have a spare pump with a pulley already on, don't you need to fit or have a relevant long bolt in the relevant pump hole BEFORE you fit the pulley because if you can't get the pully off the pump you have just removed, you won't get the bolt out to re-use it, so make sure you have a spare of that as well Cheers Rich Quote Link to post Share on other sites

As required for Unipart pumps that had a fixed pulley. Use a 3” long 3/8” unf + 3/8” unc stud (TE506241) plus a unf nut and washer. Same stud as used to hold the rocker pedestals to the head on 4 cyl TR. Peter W Quote Link to post Share on other sites
Z320 Posted July 5, 2021 Report Share Posted July 5, 2021 Yes and sorry me, I use 3 studs, nuts and washers Quote Link to post Share on other sites
North London Mike Posted July 5, 2021 Report Share Posted July 5, 2021 (edited) My spare W/Pumps always have the pully fitted and I use studs. Pops onto the studs nice and easy and, yes, one of the nuts is a little tricky . . . . . . This time I was in Italy ......

Tony_C Posted July 6, 2021 Report Share Posted July 6, 2021 Morning Hamish, great to see you are well on the way to getting this sorted with all the usual forum help and expertise…. Without hopefully sounding like a boring old b*8ger, here’s my tuppence worth learnt early on in my 40+ years of driving TR’s close to the raggedy edge, when pushing the 4 pot along at the higher Rev end if anything is out of sync or line - also if the belt is ‘excessively’ tight - then the stresses will eventually show at the weakest link, the woodruff key. Thereafter, I found I was left with two basic options: keep the revs down to5500… and or, ensure as much as possible that everything is aligned with the belt as loose as possible but not slipping and still charging (3rd option I quickly got fed up with was being towed home by Neil REVINGTON, Dave Brown, long term nameless Committee member et al) Enjoy and keep the videos coming Cheers, Tony Quote Link to post Share on other sites
