Re: Identifying Getrag trans

How much less does a 265/6 cost than a 265/5 CR? Half? It is less for gearboxes in known good condition but a 265/6 is still a sought-after transmission; it has a detachable bellhousing and it is strong enough to sit behind Aston Martin V8s, old jag E-types and so forth. If you want an inexpensive ...

Re: Identifying Getrag trans

This is very relevant to me as I'm in the process of replacing my damaged 265/5 CR - thanks for posting. I had considered a 265/6 as I'm not really into racing and I'd rather have an autobahn cruiser. I decided not to go with the 265/6 as I think I would need a new driveshaft - Is this correct? I'v...

also http://web.archive.org/web/20060714180430im_/http://www.metricmechanic.com:80/m53.gif what they call 265 is 265/6 and what they call 262 CR is 265/5, I think.

Re: Identifying Getrag trans

for some reason 265 transmissions say '262' on the side. 265/5 and 265/6 are the commonest 5s transmissions in older E24s. Both have detachable bellhousings. They are different lengths to one another and there are differences in the external castings, as well has having a different shift pattern. If...

Re: High Idle

you may have multiple problems there. However the #1 thing to do is to reset the throttle body so that there is a 0.020" clearance under the butterfly on the idle stop. (I bet it is less than that at present.) Then reset the TPS so that the idle contact is made when the throttle is fully against the...

Re: M6 E24 won't start

Put a pressure gauge on the fuel line and test it. Flow means nothing if you don't have sufficient pressure. Pumping unrestricted into a bucket can show plenty of flow even from a dying fuel pump. you are meant to test fuel delivery after the FPR, so that you are testing fuel delivery at pressure. ...

Re: Self Levelling Suspension replacement

that is a lot of money for a couple of springs to be made! Since you have nearly all the parts required to fit the standard springs on standard shocks, and the knackered SLS top mounts were the problem you started with, I suggest that you just buy the correct (standard) top mounts and get some readi...

Re: 1988 Auto to Manual Swap

you don't need a complete new pedal box necessarily; new pedal arms will go into the extant pedal box. Don't forget the clutch pedal spring compensator that fits into the pedal box. Also you probably don't need a fluid reservoir for the clutch; the extant reservoir for the brake usually has an extra...

Re: M6 E24 won't start

Compression test: 5 cylinders have about 125 #5 cyl. at 100. It is perhaps a bit knackered, judging from those figures. Q. does the engine fire on eezy-start? If so (and you are certain you have good spark) then you have to look at the fuelling. If not then maybe the compression has passed the poin...

Re: Does the OBC affect the operation of the Odometer?

I don't think so; the one signal goes into a single board and thence is used to drive the speedo and the odo.

The #1 thing that stops the odometer from working is that the gears fail.

oh, I forgot, the gearbox crossmember and the exhaust support bracket are also specific to the gearbox in many cases. Also if your car is pre 5/82 (with E12 chassis) then it needs a gearbox with a mechanical speedo drive. Later boxes don't have this option fitted. FWIW the overdrive gearbox (with th...

Re: E12 ECU question

pin 1 is (I think) the wire that grounds the coil and thus provides spark. If this is not connected correctly you will get no spark. If it is not connected to the tachometer then it probably won't stop the engine from running, but you won't get any tacho reading, obviously. The injectors are fired b...

Re: E12 ECU question

the most likely reason for your symptoms is that you have cold start injector function but not main injector function. The most likely reason for that is that the main relay is knackered (on a motronic car) but on an L-jet car there may be other causes. I would suggest that you at least test that th...
