let me know ---- i have similar problems.

i think the other guy is on the right track. done one in last few months- not a mack- i think it was a isuzu-- same problem. had to go into dealers to get fixed . started on key in 1st then just drove it into town without using the clutch.

I have a MACK / RENAULT PR 100. bus with hub reduction axles. Is there different axles available to raise the top end speed ? or change the diff ratio, or the whole diff. It has a VOITH 3 speed auto with direct { 1.00 ) final drive. Rear axle is 1021- hub reduction.Diff. ratio is 5.12:1 (2.56D / 2.00H) with a top speed of 84 km/h @2100 r.p.m. Any help or ideas ?

I have a pr100 bus with a reduction hub rear end . Is there a way to increase the top end speed thru the hub gears or only by the diff .It has a VOITH 3 speed auto 1st 5.05 2nd 1.36 3rd 1.00 rev.3.66 engine speed is 2100 rpm and a top speed of 84 km/h. the rear axle is px1021- hub reduction and diff. ratio of 5.12:1 (2.56D/2.00H)
