Exact ratio depends on input and intermediate gears that are used which vary slightly by model. Also see , , and for more information. Finally, we do not rent or sell our customer email lists. This kit reduces it to approximately 4. If so, it is possible, though fiddly, to clean and lubricate some of the linkage underneath the vehicle and to work the lever for a while to free it off.
The simplest way is to ask a garage to run the transmission on a wheels-free lift while listening underneath for the source of the noise. If it wasn't for the dirt that had managed to get in to the casing, it wouldn't need refurbishing at all, but oh well. Please contact us if you wish to make such a request. I'm in a similar state, where are you planning to order replacement parts? Click here for the largest range of parts. I need to pull the cover and count teeth. Our experience and opinion is that the more noticeable low range gear noise is not an issue because normally if you are in low range, you probably have more on your mind than listening to gears! Note the location of the drain plug and fill plug with yellow markings.
They are coming over at th e end of the month but I am still stuck on that nut, I'v tried drifting it and a pipe wrench I think I will just have to fabricate something that will get it off. All of these boxes use an integral transfer case. Image 4 of 13 Diff lock warning switch is positioned on top of the unit, seen here from the side with cover plate removed, exposing selector mechanism. It turned out to be an easy job. I'm afraid I won't have time to do a comprehensive pictures and text guide a la Les, but if anyone wants any specific pictures please say so here and I will try to take and then post them. Make sure to also order the input gear main bearings when replacing the unit.
The high ratio gears vary according to the vehicle model, with Defenders generally having a lower ratio than Discovery models. The differential is locked via a mechanical linkage through a spring inside the box. Otherwise, with the transmission floor cover removed for access, check the lock nut holding the operating arm to the pivot shaft is tight, and that the arm is correctly located on the shaft. Changing the high ratio gearing Most Defenders seem low geared for motorway and main road driving. Data has come from a variety of sources. We operate over 50,000 square feet of warehouse space at two warehouse locations on both the East and West coast.
Unfortunately there are many internal differences such as tooth counts, gear cross sectional differences, dog clutch teeth profiles etc. Oil leaks from front or rear output flange: Leakage from the rear flange might also contaminate the transmission brake shoes with oil. I guess that's what Ashcroft did to my recon unit, it lasted for 10. Note the location of drain plug and fill plug with yellow markings. Operated by the short lever in the cab, it locks the differential so that both propshafts rotate together, and are no longer independent of each other.
Examples are bogging down in soft conditions or losing traction. But I could be wrong. The symptom is a distinct knock from the central transmission area when taking up the drive, but especially if the vehicle was rocked back and forth by moving from first to reverse gear. Otherwise, the internal linkage will need to be checked by lifting the transmission cowl to gain access. Large particles or fragments warrant investigation. I am guessing this truck has had a tdi in it before it came engineless but with the inter cooler and lowered radiator mounts, hoping it was a 300tdi as then the engine mounts might be already done! We offer two kits to resolve this issue.
Shown to the right, a transfer case as seen from under body. The drain plug is magnetic, and will normally have a cluster of fine particles on it that can be wiped off. All 90s except V8 All 110s except 2. The seal can wear a groove, and that damage will quickly destroy a new seal as it rubs against it. Typically, an early Defender would have a high ratio of 1. I also realised my other case 28D.
All versions have this same ratio although there are several different high range ratios available. I've so far managed to get the box completely to pieces, including taking all the bearings off the shafts, and mostly back together again just with standard tools and a three legged puller. The other tip from the same source was to use a piece of narrow cord to suspend the intermediate gears in the case whilst you are trying to thread the shaft through them, this definitely makes what could be a fiddly job into a breeze. Straight cut gears are much more noticable in operation than helical gears although these are engaged only in low range. As a result they are very durable.
Where can I get a copy of that manual? If theres any part thats particularly tricky then by all means a photo would be helpful but a description is just as good. You may at any time opt out of this. Prefix: 4 Cyl V8 3. Diff lock works in either ratio, and also works with electronic traction control if fitted. I need to pull the cover and count teeth. Check our picture below to find the serial number to identify your transfer box. This also makes good sense when you want to replace your spares.
Slight movement can be expected here because there is always slight clearance in the parallel roller bearings supporting this flange, so it is unlikely to need attention. Image 9 of 13 Options: increased high ratio left , standard ratio centre , and extra low right which can counter the effect of larger tyres. You can easily decline or remove cookies from your computer using the settings within the Internet Options section in your computer control panel. I'm afraid I won't have time to do a comprehensive pictures and text guide a la Les, but if anyone wants any specific pictures please say so here and I will try to take and then post them. I too sarted th rebuild project last year and found out I needed some shims to et the tolerances correct on the input shaft. The problem was attributed to lack of lubrication on the mating splines of the mainshaft and transfer gear. It transfers the drive from the gearbox across and out at the front and rear of the transfer casing to drive the propshafts to the front and rear axles.
