1300 OR 1600 Gearbox?

Recommended Posts

Afternoon all.

Ive had my eye out for a 1600 gearbox for my MK1.

I found on ebay an xflow box out of a kit car that was running a 1600 engine.

It has only just been removed from the car and the seller has been running it for the last year.  So been told no noises or clunks etc.

Thing is, the owner doesnt know weather it was a 13 or 16 box. But for the price i paid it was worth a punt.

Ill be picking it up later this week. 

How do i tell if its a 13 or 16 box?

 

Cheers Rich

It’s a type 2 box used in 11/13 and 16 escorts, you’d have to work out the ratios to find out which one it was really. Just on a side note there not a very strong box and parts are getting unobtainable for them.

Ok. So i picked the new gearbox up last night.

Ive got a 1300 gearbox that i bought off of Eeb last year so lunchtime I'll compare the gearing with the two. If the two are the same then ive got another 1300 box.

If they are different, how do i check the figures? Do i use 1st 2nd 3rd or 4th or all 4 gears? Turn the input shaft 360 degrees and see how far the output turns?

I’ve got 4 in bits at the moment, I can give you a tooth count on the gears. 1100/1300 boxes should be the same. Then 1300gt/ e should be the same as 1600.

Thanks for taking a look Col.

Marked the in and out shafts on the 2 boxes and span the input shafts 10 times each. Markers on both boxes on the output shafts were at the same points. Bummer! Looks to be a 1300 box.

Im not fitting it for a few weeks. I'll take a look in my Ford manual to identify myself with the gears you mention and have a tooth count.

2nd gear is the easiest way to check mark both ends standard is about 2.3-1 close ratio is a bit less

Reading the figures Col has put seas to me that weather a 13 or 1600 box, 3rd and 4th are the same ratio anyway.

Is that right?

Here’s the ratios for both types of box ( hopefully)...lol

Transmission - Four Speed Manual Fitted To 1100 and 1300:

Floor mounted 

Gear ratio:

1st: 3.66:1

2nd: 2.19:1

3rd: 1.43:1

4th: 1.00:1 

Reverse: 4.26:1

Transmission - Four Speed Manual Fitted To 1300GT:

Floor mounted 

Gear ratio:

1st: 3.34:1

2nd: 2.00:1

3rd: 1.42:1

4th: 1.00:1 

Reverse: 4.25:

every 4 speed box has the same 4th gear ratio.

Thanks Col. 

Im happy to use the 1300 box i have now knowing that 4th is the same. Was worried that id be over reving on longer journeys.

Looks like i may have to source a 5 speed in the future. 

Another diff would probably help but i payed out near on £600  to have my 389 rebuilt last year. It owes me 🤣.

Took the gearbox out and knew i was on borrowed time with the clutch so will be ordering one this week. Also whilst its apart I'll be getting a new ring gear as that looks past its best. Want to send the flywheel to the engineer to get the friction surface re-faced. Not getting it lightened as ive heard its dangerous.

Can i fit a single piece prop to replace the 2 piece that it has now?

There no problem getting the flywheel lightened, if your thinking of going to a 5 speed in the future if the prop is ok I’d leave it. After fitting a 5 speed you’ll need a shorter prop so wait till then to replace, why spend twice.

Yeh, the prop is fine. I just thought itd be a cheap mod whilst its in bits.
