105 KKF101320 BUSH, bonded, bar to engine and dash 2 1998 on.
crossmember
The bonded one-piece bushes first fitted in 1998 replaced both the previous ‘top hat’ bushes and their
spacers. They can be fitted to pre-1998 steady bars. Alternatively, post-1998 cars can be retro-fitted
with ‘top hat’ bushes and spacers. Whichever, Somerford Mini’s recommendation for longevity is to fit the
USBK001 steady bar heavy duty bush kit shown later in this section to all models!

Introduced at the same time as the rod change gearbox, the lower RH rear steady bar was intended to
replace the engine bracing so well effected by the previous gearbox’s remote change housing. Since it
secures at one end to existing studs and nuts on the power unit and on the other end to a simple hole
in the subframe rear leg, it can be easily installed on the majority of Minis, if desired.

Lower Left Hand Rear Steady Bar
998 and 1098cc 1976-78
For 1976 it was decided to replace the lower RH rear steady bar on 998 and 1098cc models by fitting
a similar set up on the LH side of the engine, again anchoring to a subframe leg. The lower LH rear
steady bar assembly can also be easily fitted to many Minis, if required. The factory did not fit it to
848cc or 1275cc Minis - both soldiered on with the RH bar until the next design appeared in 1978.

Lower Right Hand Front Steady Bar
All Models 1978 On
The final variant of the lower steady bar, running forwards from the gearbox to the front crossmember
of the subframe, appeared in 1978 and was fitted to all Minis up to 2000. It replaced both previous,
rearward facing, versions. When the 1275cc engine was reintroduced in the Mini in 1990, the engine
position was moved slightly so the lower RH steady bar for all 1990s 1275cc Minis is slightly shorter (by
1/2") than for all other models. Incidentally, looking further back in this section of the catalogue, that’s
why 1990s 1275cc Minis had the longer (previously automatic models only) upper steady bar.
The good news for owners who already have one on their car is that the lower RH front steady bar
works better than the previous two rearward facing designs; the bad news is that if you have a pre-1978
car, unless you also ha ve a post-1978 front subframe with the necessary bracketry welded to it, it
wouldn’t be easy to fit one.

Heavy Duty Steady Bar Bushes
Soft or disintegrated steady bar bushes are one of the most frequent problems on Minis. Identifiable by a
knock from the dash panel upon sharp throttle movements, loose bushes also result in jerky acceleration
when the engine ‘snatches’ on the throttle cable - which then causes further bush deterioration.
The best solution is harder, more resiliant bushes - but beware! Use of very hard or solid bushes may be
acceptable for out-and-out performance Minis, but they do result in loss of refinement in a road-going car
and can even cause premature failure of steady bar securing bolts or brackets unless careful fitting and
maintenance is carried out. Somerford Mini recommends the use of their heavy duty harder (but not too
hard) rubber bushes for all road-going Minis , pro viding greatly improved resiliance to wear without
increasing stress on the steady bar and its fixings. The bushes utilise standard spacer tubes and bolts .
The Somerford Mini heavy duty steady bar bushes are available in an upper steady bar bush kit (four
bushes and two bush spacers), or as individual bushes for fitment to either upper or lo wer steady bars .
Note that they are not suitable for fitment to the engine end of original 1959-62 upper steady bars .

146 CRC5329HD BUSH, steady bar, harder rubber 1 For upper or lower steady bars.
Included in USBK001 kit.
Broken Steady Kits
What’s even more frustrating than worn out upper steady bar bushes is one or both of the mounting
bolts shearing off in the cylinder block when you try to replace them! Sometimes one or both block
bolts have even been sheared beforehand by the shock caused by ineffective bushes. Either way, a classic
situation of a five minute job turning into a major exercise can result if engineering workshop techniques
or tools such as ‘easy-outs’ are required to remove the remainder of the bolt(s). Somerford Mini can
supply an easy-to-fit mounting bracket assembly,bypassing the offending engine block bolt holes.
The four broken steady kits provide alternatives for use on cylinder blocks where either the longer bolt
only or both bolts have broken, on engines without or with a crankcase breather on the flywheel housing.
Each kit includes an adaptor bracket, plus the bar retaining bracket with appropriate bolts and washers.

Upper Left Hand Engine Steady Bar Kits
Really only recommended for very fast road or competition use, these steady bar kits mount at the
opposite end of the engine, supplementing the standard RH steady bar. Attachment methods vary in
detail, since the Mini was never originally designed for them, but they all share the principle of bracing
the engine between the thermostat housing and the left hand end of the dash crossmember. Kits include
steady bar,bushes , bush fixings, attachment brackets and extra bracket fixings (as appropriate).
