Steering Column Rotor Halves

Steering Column Rotor Halves

Has any one spare rotor top and bottom halves (pt Nos C.10319 and C.10320)
for XK150 or knows of a suitable substitute,possibly XKE? Unobtainable new
here in UK and holding up steering column rebuild. - Regards Chris

Chris, Terry McGrath has advised me that the company I mentioned previously
for supply of the rotor kit is "British Auto USA".  They have a web site
well worth visiting at  You can contact them by
email and also order a free catalogue!
 Your OTS is a little later that mine (1958 150S OTS S830895 DN} which was
also first exported to Jaguar Cars New York. - Cheers Col Haywood

I was just getting ready to call and had the address/phone handy. British
Auto/USA,  92 Londonderry Turnpike, Manchester, NH 03104 Orders: 1 800
452-4787, Inquiries: 603 622-1050, Fax: 603 622-0849 - Terry Mann

I give up....what are Rotor halves... let alone tops and bottoms ??  I
don't have a 150 parts manual or I would look them up myself. Thanks - Andy

They are the insulating mouldings which fit under the slip ring on the
inner steering column to prevent the slip ring permanently shorting the
horn circuit to ground......and mine have completely disintegrated!!!!!! -
Chris Hannan-Babe

Thanks Chris...I would have never guessed. - Andy Leavitt

Chris, I made mine on the lathe from some black Poly-Pipe, time consuming
but not too difficult.  Terry McGrath knows of a place in the US where you
can purchase a kit including all the parts required...also covers Mk2 etc.
I think that the cost was about US$65. - Col Haywood

Hi Chris Hannan-Bobe & all -- the "slip ring" is NOT unique to the
XK-series cars!  My original Mk IX has one, according to the Spare Parts
Catalogue: P/258: C.13960, Horn Slip Ring Assembly -- 1; C.10317, Slip Ring
Only (348276) -- 1; C.13961, Cable, complete with Contact -- 1; C.8761,
Contact for Cable (348266) - 1; C.8156, Spring, inside top half of Rotor,
for Cable tension (348267) -- 1; 8295, Rotor (54300638) -- 1 (but Plate 58
shows two pieces, #29); Plate 58, p/261 -- shows slip ring assembly at
lower end of Inner Column. I've never had this out -- never been necessary
-- perhaps I should do it anyway just to check on condition, especially
after Chris HB's comment! Also posting this one to the saloons list -- if
my saloon has it, others will, too - Larry Martz

Regarding the rotors). I looked everywhere for replacements and even called
England. I was told they are the only parts that can't be replaced.
Solution. Remove the bearing cups, clean and lubricate. Replace bearings if
necessary. Then use a solid round neoprene piece to replace the rotors and
force it on the shaft over the brass slip ring pinning the wire under it
between it and the slip ring. It works like a champ. Good luck. I just
purchased a Mark IX and am disappointed to learn it has the same horn
setup.  Oh well! - Bob Cathey, xk140mc and Mark IX
