Maverick and Terrano 2.7TDi Gearboxes

[Banshee]

Just been having a bit of an argument on my lunch break with this massively cocky ex Ford Master Technician whose understanding of glow plugs sickened me given the amount we pay these monkeys to fix our cars (I don't :sly)

He actually thought that the plugs "bathed" in the fuel and warmed it up whilst the car was running :doh, he also told me that having glow plugs on a Direct Injection car did nothing for cold starting :doh:doh and that they were only there for emission control

After telling him he was wrong he then went on to tell me that the gearbox on a 2.7TDi Maverick wouldn't fit a 2.7TDi Terrano, he told me that they were different and that one of the noticeable differences was the fact that the Maverick didn't have a synchro for reverse whereas the Terrano boxes do.

I didn't have enough knowledge on this topic to argue with him so I've brough this one to the table here to see if one of you lovely gents could enlighten me

Ah. Tosh tastic . The maverick is simply a re-badged terrano. Not a re-engineered beast ? There may a difference from the TD to the TDi possibly ?

 

[R1cho]

there are some very subtle differences between the two but i do know the gear boxes are interchangeable after recent events i have looked into this under the bonnet some things are in different places but essentially its the same, i thing the egr is in a different place on the maverick and harder to get too.

Go and twat him with a wet fish :doh

We were talking about a TDi of the same year of both a Maverick and a Terrano

Are you talking about TD and TDi here? As we were talking about TDi Maverick and a TDi Terrano

Go and twat him with a wet fish :doh

I'd love to :clap

I hope you drove over him:lol It's plan to see this so called tech knows nothing at all about diesel engines as glow plugs heat the air in the cylinders:augie now the bit about a synchro mesh for reverse gear i'm sure the Terrano doesn't have one as as both of mine have at time been a little stiff to get into gear & have to select 1st then go to reverse to line up the gears:augie infact I can't think of a car that has a synchro mesh for reverse gear

15 years in the trade apparently lol, clearly an utter bellend who knows nothing about engines of his era

I'm sure someone like Rick or CNCFabs will be along soon to give us a definitive answer

a synchro mesh for reverse gear

Um, one gear,


So what you going to synchro it with.....

Ford Master Technician....:jesterbg

When I bought my New Mav from a Ford dealer in Cannock.
I had to return it after services as they had created oil leaks etc.

They hadn't got a clue in 1995, so what do they know now, as the Ford Maverick hasn't been built for approx 10 years ? :augie

This is exactly why I came to you guys so how does a synchronesh work?

 

[Barrbeast]

I would check the likes of wikipedia for the detail on how it works but syncromesh is what allows you to change gear smoothly - without syncromesh you would get a horrible crashing/grinding noise from the gears trying to mesh every time you tried to shift on the move in the normal way (non-synchro gearboxes are called crash gearboxes for that reason). To avoid the gears crashing you have to use a technique called double clutching.

I've driven tractors that were made in the 70's and 80's and didn't have syncromesh - I don't know how to double clutch and every time I changed gear I expected to see bits of metal left lying in the road Far as I know some lorries and other heavy equipment still don't have syncromesh.

I know some Leyland tractors had syncromesh in reverse which allowed you to shift into reverse while the tractor was still moving forward (apparently made them really handy for loading duties) and I think some cars did as well.

No T2 or Mav has ever had syncro on reverse, in fact no normal road going motor has, as for glow plugs they just glow in the combustion chamber so helping burning of the atomised oil in cold conditions, nothing special, Rick

double de clutch going up is simply foot on clutch, disengage gear foot off clutch to slow first motion shaft down, foot on clutch, select next gear, going down foot on clutch disengage gear, foot of clutch, blip go faster pedal foot on clutch engage lower gear, simples Rick

All in 3 second, and he says simples :clap

3 seconds will be a bit slow, when out on the road next I will time myself, Rick

:thumbs:thumbs:thumbs i've had to do it a few times as I used to work on classic cars, takes some getting used to:doh TBH I often blip the throttle during gear changes when the gearbox oil is cold as I find it makes it a lot smoother on a Terrano:augie

Synchromesh

This is exactly why I came to you guys so how does a synchronesh work?

No such thing as a separate synchromesh for reverse as it effectively uses the first gear synchromesh via an extra gear. Many older vehicles had no synchromesh in first gear (as in early BL Minis) so would then have no synchro in reverse.

A synchromesh is like a mini clutch & hub, it is a tapered part usually made out of a bronze type metal with a ribbed face. It spins the layshaft speed up as it engages gear so that the speed of the mainshaft and layshaft become equal as the gear engages to stop the crunching noise.

It's a misnomer in way to talk of changing gear as the gears themselves are permanantly meshed on the mainshaft and layshaft - the gear engagement consists of one gear hub/synchro being selected via the selector fork to lock it on the gearshaft.

There are a number of designs as to how to lock the gear selection in place - on older motorcycles it consisted of three roller balls being pushed out by a central shaft to lock a gear in place.

Synchromesh is, to put it simply, the arrangement of a set of matching cones that, when forced together, use the friction between them to cause one gear to literally synchronise it's speed with another & thereby ease engagement. I'm sure some Fords, years ago, had this on reverse but it is quite unusual as reveres gear should be engaged only when stationary.

Unrelated but may be of interest; when I owned a Hillman Imp (1970's) it's synchromesh was soooo good it was quite possible to change up & down without using the clutch.......'what fun!'

I can do that in my Maverick now both up and down!!!!
