Increase speed AR 160

Took my International AR160 for its first run since restoration and found top speed is around 70 Kms/hour. Any faster and the motor is revving too hard. Has 2 speed diff fitted. What is easiest solution....Change crownwheel and pinion, fit overdrive joey box into tailshaft [plenty of room to do this] or are there any other options. Would like to get at least 90 kph if possible. Thanks

U can try different ways to grab a k or 2
but just cut to the chase
n fit a joey box arse bout to give U sum tall gears
If n the donk can propel it @ a faster speed
Guessn it could B a handful try n to contol it @ break neck speed
as it waz designed to do bout 80kph

One of our club members has an AR162 and it cruises at 90ks. Is your diff in high ? What size tyres have you got ?

I am finding it almost impossible to use this forum. I have to spend a lot of time just blundering around until I eventually stumble onto where to put on a message and although I use my name it comes up as anonamous and shows me as a non member. I have been involved in other forums and had no difficulty whatsoever. I want to reply to an answer I got to my original post but cannot find how to do it......the other forum I have been involved with had a 'reply' to click onto if you wanted to. In answer to the reply to my original post...The diff is definitely in Hi range and the tyre size is 825x20 and at 90 kms/hr the engine would just about fly to pieces at the revs needed. Maybe I am just too old for this modern technology Thanks for replies so far

Is that me you are referring to Atkipete?

Anonymous what are you referring to as too hard? What motor are you running? They get a nice hum up when on song which is the 80-90 Kmh range but it is loud if used to a car or modern truck. They will run All day at 3000 rpm.

When I was running the ASD240 it would sit at 85-90 Kmh on the flat but noticed every slight rise in the road. The 281 seems happier at 80 - 85 but doesn't feel all the rises so the actual travel time doesn't change much.

With either motor the low diff ratio ran you out of revs at around 60 -65 Kmh. So if the motor is revving hard then maybe t isn't changing. However before you panic about that what size tyres are you running. Mine are 8.25 .

I have a water pump and some other bolt on bits for a silver diamond motor if you are interested. I want something for them but not gold plated prices

That's your lorry Bruce.

Finally got the forum worked out. I drove the AR and AS Inters when they were new so have a fair idea when they are reving too hard. Will have to look at altering the diff ratio as the 2 speed diff I put under it possibly came out of a truck with overdrive gearbox....something I did not check at the time

Have you checked speed with a GPS, speedo may not be accurate. ?

Checked against 2 seperate fairly new cars
