[@NWIndyKiwanis]

Just like riding a bike

[@davidwyby]

That sound...

[@Orvz475]

How did he single-clutched it without grinding eventhough it's unsynchronized transmission with a direct drive 5th gear was from a gas powered 5 ton?

[@Slim_Slid]

That five ton truck isn't gasoline powered...It's a M818 and the M812's-M820's all came with a naturally aspirated NHC-250 from Cummins. The transmissions in these trucks actually do have synchronized gearing,otherwise he would have to double clutch.The deuce and a halfs are the same way.

@@Slim_Slid Pardon me. Some of the older gas powered 5 ton trucks have been converted to either Mack diesel or the Multifuel engines, yet still had the direct drive 5th gear trans instead of replacing them with the 5th gear overdrive trans like the Cummins NHC-250 powered ones that you owned, according to my sources.

@@Orvz475 That's the M51-M543 you're referring to,which had the Continental R602 when originally being debuted.Once the M51A1-M543A1 came out a few years later then they had the EDNT-673 Thermodyne from Mack and were manufactured at Mack.Later on they came out with the M51A2-M543A2 which were multi-fuel powered from Continental,Hercules,and White Motors.Most of them had the LDS-465 because of the torque.The LDS-465 is 175 HP/447 TQ compared to the LDT-465 at 135 HP/330 TQ that many of the two and a half ton trucks had as A2's when the LDT-427 in the A1's was 140 HP/340 TQ. For the M51-M543 they had the Eaton 6352 and the M812-M820 had the Spicer 6453.
