type 9 advice / opinions required
ditchlewis - 8/5/12 at 02:58 PM

I realise that I has been discussed before but I'm after your opinions.

The question is how much power and abuse will the type 9 take before packing up altogether, and am I flogging a dead horse?

I have a 160bhp+ pinto which revs to 7K rpm in my MK and this weekend I developed a nasty rattle and I believe that the thrust bearing has come off the fork.
this will necessitate taking the engine and gearbox out, so whilst it is out I have a decision to make. Do I replace the gearbox? Or take the opportunity to repalce the seals and put back in.

I'm using the car for road use and I like to accelerate hard but it is not the abuse a track day or racing would impose. With the indy being a much lighter car than the sierra the abuse would be reduces would it not?

My wifes credit card bill has put serious clamp on spending so a heavy duty type 9 is going to be a real problem.

When the box is out I was going to take the top off, what should I be looking for inside? How much play should there be in the input shaft?


I was hoping to get away with new oil seals and gasgets circa £60 rather than new box circa £600.

I really dont want to spend large sums of money I don't have, but also I don't want to keep having problems.

Your opinions please

Madteg has a standard type 9 in his 340bhp turbo car... he told me its been in there for years with no problems, mine will get its chance with my turbo setup as well

I've popped three diff and three half shafts but never had any problems putting 200bhp through the type9.

I ran a 220 bhp Vauxhall on a standard type 9 for 2 years with no problem
They ain't that expensive and you could always keep a spare in the garage

If funds allow then a heavy duty gear set with better ratios is nice to have

I have a similar power zetec in my car and am still using the gearbox that I fitted back in 2004 and abused ever since , I did not even know if it was any good as i picked it up off the floor in a local scrapyard thinking it would be ok just to get the car running with.Last winter I did drain the oil as it was starting to get a bit black and some gear changes were a bit notchy but after refiling it with EP 75/8 semi synthetic it is now back to a nice smooth gear change.
Lots of people seem to get away with higher power outputs as the traction limits the maximum torque through the box.

Thanks for the good news lads, made my day.

I will just replace the oil seals and gaskets and have a look inside. As you say you can pick up a spare quite cheap and a lot cheaper than the £600 some want for a good recon.

I think I will also replace the thrust bearing also.

Is it possible to put a "retainer" on the fork to prevent the thrust bearing coming off again?

The thrust bearing shouldn't really be able to fall off once it is assembled to the engine, i recently did the clutch on mine and found the bearing that I had did not seem to clip on very securely but decided that it could not fall off once fitted unless there is to much slack in the cable.
