Ha ha. No, won't work miracles.

Hi all I have read many topics / threads on gear oil for our buses and have determined that, for my 5 speed ASS box, original spec is 80w90 GL4 mineral oil. I have also read on here that GL5 is a no no, and synthetic is recommended. A GL4 / GL5 may also not be suitable. Also, a 75w90 GL4 should give...

Good info thanks and enjoy the smooth running bus

+ 3 for the coil. I had the same problem. As everything fuel wise has been changed (several times!!) except the carbs, I would guess ignition as it is unlikely that both of the carbs is failing identically at the same time. As this is an air cooled 2L, it will have electronic ignition and need a par...

Great info thanks. Where did you find that?? I think I need to find out the gearbox codes on the 2 buses so I can at least check the ratios. As it happens, the water cooled one is a 60bhp DF engine, so the air-cooled CU has more power and torque!

The chokes won't set to the closed position until the accelerator has been pressed to release the fast idle cams. Check that first other wise the chokes may have been adjusted to not come on for some reason. No difference between autos. Thanks for the advice. Will check it out. I see you are probab...

Forgot to say, one with closed butterflies is auto gearbox and the other is manual - just incase the electric auto choke is set up differently!!!

Have got 2 Aircooled buses and was doing a bit of work on both on the same morning. I had the air filter box off on both and noticed that the carb choke butterflies were both closed on one and both fully open on the other! I had not started either of the buses on that day so they were both at the sa...

Struggling with this one!! Don't want to have to take 2 gearboxes out for the sake of it. Must be someone who has tried it or knows the answer? I know WC and AC manual gearboxes aren't a straight swap, but little info on the auto

Anyone??.

Hi.

Did you ever find out the answer to this question? Did you get it and did it fit?

Thanks for the reply. I did PM Aiden before posting, but he doesn't have much experience in the auto box's. Expert on the manuals though and really helpful :ok I am amazed how little info there is on them on the net. Baring in mind they were fitted to loads of VAG motors, there is almost no info :?:...

Hoping some one may know the ansew as I have been googling for days!! I have a water cooled DF engined 84 T25, which has had a £1,000 gearbox rebuild on its auto box about 10,000 miles ago. I also have an Aircooled, CU engined T25 with an auto box. Question is, are the two gearboxes inter changeable...

Hi all Probably should have done a little more research before purchasing an ABN 5 speed box and linkages to fit to my CU engine! I understand the top gear ratio / final drive is a little lower (about 5% overall), but brand new tyres should make up this difference, or higher profile / larger diamete...
