Here you will find information on parts exclusive to Glencoyne Engineering.

Trade / bulk orders please contact me as I can probably do a deal.

SERIES GEARBOX SELECTOR SHAFT SEALS (updated September 2026)

Many Series owners will be familiar with oil dripping off the bottom of the gearbox from the gear selector shaft seals. Land Rover used plain rubber rings with pressed steel retainers: these worked well enough when new but the rings available now are often a very sloppy fit. Also the shafts run direct in the aluminium casing which wears over time allowing more oil to reach the seals.

Late Series III boxes had a revised arrangement with O rings and spiral PTFE backup rings (FRC6938). These seem a bit better but not perfect, and the backup rings are only available as new old stock and madly expensive for what they are. I am now able to offer a better solution to this very common issue.

It uses two FKM (Viton) O-rings per shaft, retained by much stronger laser cut steel plates. The kit includes Viton O-rings for the high-low and 4wd selectors on the transfer box which should stop leaks from there as well.

The seals can be fitted without removing the gearbox (although it is a bit fiddly with the seatbox in place). Detailed fitting instructions are here: https://tinyurl.com/32w857z6

ENGINE MOUNTS (updated Jan 2024)

For several years I sold high quality engine mounts for older Land Rovers.  These "bobbin" mounts (part number ANR1808) were made in the UK from high quality rubber and had a huge effect in reducing engine vibrations especially on 200TDi conversions.  My original supplier discontinued them and after some research I found another UK manufacturer who could supply mounts of near enough identical specification, the only difference being that the threaded studs were slightly longer.

These mounts fit engine and gearbox on all four cylinder Ninety / One Ten and Defender up to the end of 200TDi production.  They do NOT fit 300TDi or later vehicles. They will also fit Series vehicles but are larger diameter than the original Series mounts and will need the steel end plates trimming with an angle grinder to clear the mounting brackets. 

I have now sold more than a thousand of these mounts and people love them. They are made in small batches so availability can be a little patchy. New deliveries are announced on my Facebook page so keep checking there for news.

CARBURETTORS FOR E10 FUEL (updated Jan 2024)

Since the introduction of E10 petrol (10% ethanol) I have seen a lot of problems with Zenith 36IV carburettors in Series vehicles. It turns out that the O-ring which seals the float chamber is not E10 resistant, allowing raw fuel to be drawn into the intake. I have now sourced O-rings in Viton™ and can offer a 36IV overhaul kit with this O-ring, as well as new reproduction 36IV carburettors modified, fettled and rejetted for optimum performance on E10 fuel. I have sold around 50 of these carburettors so far as well as fitting them myself to half a dozen vehicles for customers, all of whom have been very happy with them.
