Copyright Notice: This item/modification design is protected under UK Unregistered Design Right (UK UDR) legislation from November 2010 for a period of 10 years.
For Right-Hand Drive Models
This is a Modified EXCHANGE Item with all NEW ALL-METAL BUSHES
A custom-made upgrade, free moving and virtually No Freeplay! (typically 0.04mm or 2 thousandths of an inch).
You need to send your unit in to be modified / exchanged .
The Idler-Relay assembly is stripped back to bare metal and any damaged balls replaced with new. The relay is sleeved with self-lubricating metal bushing for the full length and fitted with a grease nipple for additional lubrication in future. The whole assembly is drilled out 25% larger than the original to accommodate larger fully-shouldered hinge bolt and then hand-reamed for close fit. Finally the assembly is painted in 2-coats of high-zinc paint followed by a top coat of lacquer and assembled with a cleaned neutral spring (where appropriate, depends on the model).
Please note the Exchange conditions shown elsewhere on this site.
See Video demonstration at the end of this description.
The original nylon bearing system is completely removed and replaced by machined metal bushes for almost the entire length with zero twisting action. The relay is a significant part of the linkage assembly and this upgrade eliminates freeplay in this area, leading to a more precise selection of the "gate" and gears.
Also included is the upgraded O-Ring , although for moderate-heavily worn selector shafts a "sleeved" collar is the only option likely to work . The sleeved collar (see separate listing below) has 5 times the bearing surface of the original and is made to a finer tolerance.
The relay unit is supplied greased, pre-adjusted and ready to fit. A Grease nipple is fitted to allow periodic greasing although the use of self-lubricating means this is not really necessary any more
NOT all units are fitted with neutral selector springs (as shown in the photo). This was Removed from late linkages (approx 1990 manufacture) when the gear lever was modified. SEE NOTE BELOW.
Do you need a Neutral Spring?
Sometimes: I recommend you replace like-for-like, i.e. if your existing relay has one fitted then use a modified relay with one fitted. If you do not have one fitted please be advised that the spring is not essential to the operation of the linkage and as only used on the linkages circa 87-90 manufacture, after which the gear lever was modified (again) and the spring removed. Fitting a spring where there is not already one is NOT recommended as it makes the gear lever much stiffer in the left-right movement.
If you require a neutral spring but do NOT have an exchange one on your exchange relay then this incurs an additional £5 charge to cover the cost of the spring.
