PodOne Posted November 10, 2019 Report Share Posted November 10, 2019 (edited) Hi folks I thought I'd spend an afternoon trying to sort the original LUCAS waster motor and bottle. I'd planned to simply fit a new motor to the top of the bottle as the original was just a pile of rust when I split the case but the new one looked naff and I wanted to keep it looking original if possible. Its a squeeze and took a fair bit of fiddling but from the outside it looks original and works well. Just need to sneak the washer bottle into the dish washer which makes a good parts washer just don't blame mw if you get caught! The plastic Motor case needed filling down to allow the screw heads to sit lower and the motor/wiring was all sealed in silicone Edited November 10, 2019 by PodOne added info Quote Link to post Share on other sites
stuart Posted November 10, 2019 Report Share Posted November 10, 2019 Well done, thats a good way of keeping the original look. Stuart. Quote Link to post Share on other sites
Mk2 Chopper Posted November 10, 2019 Report Share Posted November 10, 2019 That's something I've planned to tackle too, at least I know it's doable. Thanks for sharing. Gareth Quote Link to post Share on other sites
BlueTR3A-5EKT Posted November 10, 2019 Report Share Posted November 10, 2019 Well done - an elegant solution. Peter W I think it is the same trick the re-makers of the new glass bottled Lucas Screen Jet system for the sidescreen cars uses. Originally the pump, submerged in the bottle, was driven by a motor, fitted in the lid. The drive from motor to pump was via a shaft in a vertical brass tube. https://www.sngbarratt.com/uk/#!/English/parts/5443aa9a-9e8b-47d1-b412-4ef0c331fcf3 Quote Link to post Share on other sites
Keith66 Posted November 10, 2019 Report Share Posted November 10, 2019 Hi Almost at the same point. V weak original motor but don't like the look of the new one i bought. As Gareth i was thinking along these lines but i'll now def be giving it a go. Cheers Keith Quote Link to post Share on other sites
Mark69 Posted November 10, 2019 Report Share Posted November 10, 2019 (edited) Well done, I also dislike the available replacements, so was really chuffed when I found mine to be working, downside I had to replace the bottle due to a stress crack. Replacement bottle fits very well and cap also secures tight. But the bottle walls are thinner than the original. Edited April 14, 2020 by Mark69 Quote Link to post Share on other sites
harrytr5 Posted November 11, 2019 Report Share Posted November 11, 2019 Thats brilliant! Thanks for sharing. TR Shop had new ones made with a modern motor some years ago which I have in my TR5 and looks the part. Regards Harry TR5 Nutter Quote Link to post Share on other sites

Andrew Smith Posted November 22, 2019 Report Share Posted November 22, 2019 4 hours ago, AarhusTr6 said: Hi Did the motors all have covers? Rich No, the black cover was a carryover from the TR5 for the early CP TR6's, later CP cars and all post-73 CR TR6's were fitted with the exposed motor similar to the donor used in the conversion above. I'm sure Derek Graham will be along and can advised of the change over point. Cheers, Andrew Quote Link to post Share on other sites
AarhusTr6 Posted November 23, 2019 Report Share Posted November 23, 2019 Thanks. To me, it makes logic sense to have a cover over an exposed motor and wires. Quote Link to post Share on other sites
Drewmotty Posted November 23, 2019 Report Share Posted November 23, 2019 One of our local group has used a control box cover to hide the exposed motor on a later car. It looks like it was always there. Quote Link to post Share on other sites
Mk2 Chopper Posted February 4, 2021 Report Share Posted February 4, 2021 (edited) Thought I'd update: finally got round to looking at this. The original motor was still fitted to my washer bottle but another washer motor was installed in the engine bay above the bottle. I wanted to dismantle the original motor as I was sure it would probably work with some clean up etc, but the screw on top wasn't very good and I couldn't get it undone. Fast forward a great deal of time, I decided to give it another go, brought the bottle indoors and found a different set of screw drivers and managed to slightly tighten the screw and then very slowly undone it. Two smaller screws underneath (one snapped) it came apart. Cover now off and I can see some corrosion on the steel connected to the magnet, and the rotor didn't want to move freely, but the windings looked good and the commutator was a bit dull but ok and plenty of meat on the brushes. First i dismantled it and realised the metal coming off the magnet was too tight on the rotor, so gently tweaked it to open it slightly, now the rotor turns! So I cleaned all the connections between the brushes and the connectors on the outside and put it back together, now it turns with power. I reassembled the washer bottle and tested it and sure enough it can push water through the jets. Now the plan is to treat the rust inside, add some grease to the rotor shaft and polish the commutator up a bit and find a replacement screw. Oh and clean up the housing a bit.

BlueTR3A-5EKT Posted February 4, 2021 Report Share Posted February 4, 2021 Nice screwdriver. My preferred tool with bits in the handle. You will need a filler cap too pt no GWW957 under a fiver from most specialists. Peter W Quote Link to post Share on other sites

I think they used some bottle top before. Yes I've had that Snapon screw driver for many years and it's still going strong. Also do you know where I could get the strap that hold's the bottle without buying the whole bracket? Edited February 4, 2021 by Mk2 Chopper Quote Link to post Share on other sites
aardvark Posted February 4, 2021 Report Share Posted February 4, 2021 I did my strap with Pirelli webbing from woolies I think. You have to cut it down but once done, it looks identical to original. Quote Link to post Share on other sites
Mk2 Chopper Posted February 4, 2021 Report Share Posted February 4, 2021 Ahh thanks man, that will tidy it up quite nicely thanks. Gareth Quote Link to post Share on other sites
BlueTR3A-5EKT Posted February 4, 2021 Report Share Posted February 4, 2021 Did someone mention putting the plastic bottle and other bits in the domestic dish washer. Same technique to refresh plastic lamp lenses. Ercol also do beige 3/4” wide rubber straps for upholstery. Peter W Quote Link to post Share on other sites
Mk2 Chopper Posted February 6, 2021 Report Share Posted February 6, 2021 (edited) Another update: I cleaned the bottle as best a I could but it wasn't great, but I also found a crack in it. So I went to price up a replacement and that's when I discovered I had the early bottle (from a TR5/250), and from CP 50001, according to the supplier's, on it was the square bottle - see Derek's correction on that below. So pricing up a new early bottle and filler cap came to around £27. The square bottle that doesn't need the extra filler cap and new mounting bracket with new rubber that i need was about £28, so it was a no brainer to get the correct square bottle with new bracket and sort it all out in one go.

saffrontr Posted February 6, 2021 Report Share Posted February 6, 2021 Well done on fixing the washer bottle motor looks like I should do the same with a non working spare that I have lurking in the garage. Incidentally the squared off bottle is correct for all TR6, maybe a couple of the early press TR6 had an oval one carried over from the TR5/250 but it was only ever the squared off one that was listed in the parts books. See attached factory under bonnet image of CC27025L showing a squared off bottle, this TR6 was built in early December 1968. Derek Quote Link to post Share on other sites
Mk2 Chopper Posted February 6, 2021 Report Share Posted February 6, 2021 Thanks for the correction there Derek, always good to brush up on the historical facts. I think the suppliers are a little more loose with the dates things changed, implying the '69 model year carried over the TR5 bottle. Definitely have a go on your motor, these things are pretty robust by the looks of things and pretty simple. Gareth Quote Link to post Share on other sites
Tom B Posted April 6, 2021 Report Share Posted April 6, 2021 Sorry to resurrect an old topic. I was refurbishing and cleaning the washer bottle motor Lucas 5SJ. The brushes on the washer bottle fell off on disassembly. I re-soldered them but it doesn't look a very robust fix although the motor does run and the assembly pumps water. I have seen second hand motors on eBay and may go down that route. I may also resort to the solution above (which is probably the better option). Despite scouring the internet, I have failed to find replacement bushes. I find that quite surprising, as generally, brushes for Lucas motors seem to be available. Has anybody had better luck?

Waldi Posted April 6, 2021 Report Share Posted April 6, 2021 Your brushes do not seem too bad, similar to what is in my pump. After cleaning I just bent the arms a bit to have a bit more force, not much off course. This did the trick for me. Waldi Quote Link to post Share on other sites
