- Stripping down the M40 gearbox, techniques, and what to be careful of. The M41 (overdrive) gearbox is an identical procedure, just the rear housing differs.

Excellent video! Do you have any on the m45 and overdrive rebuilds
I've not had the opportunity to try an M45 David, so I know nothing there regrettably.
Overdrives I've always regarded as a specialist area, and we simply send them to Dave at Overdrive Spares, who can also uprate them with stronger clutch lining and winding up the oil pressure a touch - both of which the D-Type needs, but J- & P-Types don't.
Hi amazon cars. What happened to your rebuild video for the m40. I watched it once and it seemed to be about the only good video on how to do it. I do hope it is still up.
I was wondering if some videos were removed? couldn't find the other videos I watched before. Removing m40 gbox, replacing diff seals, etc., cheers
Hi Joseph, they've moved to our Patreon gateway patreon.com/amazoncars
This change from free vids to subscription is in an endeavour to pay for the hardware and time that we spend on creating the how-to's. We hope it will permit us to improve and increase the number...

Is the m30 the same size as the m40 or are there any differences? The outside of the gearbox ofcourse.
Hi, the answer is no. They are identical sizewise.
hi is the speedo cable a common place for the m40 to leak? My one has a leak and it's around speedo cable, should replacing the oring gonna fix it?
Not particularly common, it's more often the tailseal. However there are two important seals on the speedo drive: there's the tophat seal between the cable "nut" and the threaded post; then there's also an O-ring on that fitting that holds the cog itself. Sorry, not an excellent description, but the parts diagram illustrates it nicely - send me an email if you want a picture.

@@amazoncars thanks rob will look into the tailseal part. also i couldn't find any email from your 'About' section. cheers

How do you take off the reverse gear ?
That needs the correct puller,: since we've only needed to do it once in 18y we get our local machinists to extract that pin from the rear of the 'box - so I haven't got a picture of the tool for you (sorry). Rob
I HAVE 144 VOLVO 1975 ....SHOW VACUUM CONNECTION & HEATER VALVE PLS
Sorry Andy, I don't have a late 140 in the workshop, and there's none booked in for the coming year either.
Rob
@@amazoncars THANKS
MY REAR AXLE STATES 4.0. ON THE PLATE
ID LIKE TO BRING MY REVS DOWN AS I HAVE M40 BOX NOW CAN I USE ANOTHER AXLE????
@@andypetersen4282 Hey Andy, "4.0" doesn't make sense to me: the automatics had 3.8 but I think they had a special diff carrier. The usual fit for M40 cruising would be 4.10, and for sport fit the 4.56 or possibly 4.30
Rob
THANKS ROB.
Nämen har ju en sån på epen
My apologies Fjaras, my Swedish is too weak to understand! Rob
@@amazoncars he says hes got one on his "epa" which is a type of car you can drive in sweden from age 15 but due to the special rules, they need to go max 10 kmh on 2/3 of the max rpm on the first gear so you use 2 gearboxes that are linked together, most often Volvo M47- M40
@@nisse4629 Excellent, thankyou - I shall look up more about them... Rob
