Christopher, it runs in oil. This means that when released, oil drags the disks along with it, so getting into gear after a stop can be a challenge. I don't have personal knowledge, but I expect that the reason the maker installed them was for a longer service life. You can overheat a dry disk clutch setup astonishingly quickly in a heavy duty rig. For what it's worth. Tom Caffrey PD4106-2576 Suncatcher Ketchikan, Alaska | ||

It's no harder to drive a wet clutch than a dry type, once you're accustomed to it's nuances. Your shift (double-clutch) timing will change as the oil heats.. In very cold weather, the wet clutch challenges you to figure out how long to wait before attempting to go into the next gear... or downshift.. When coming to a stop in cold climates, we usually shifted into first as we came to a stop. Trying to get it into first after stopping (in freezing weather), upset passengers who assumed you must be a new driver, the way you grind gears.... The benefits outweigh the challenge (if you're the owner of it), since maintenance (adjustment) of the clutch was usually rare. A wet clutch usually lasted a ton longer than the dry type, and seemed as if it provided for a much smoother take-off. That clutch should be the least of your concerns... Have the rig checked out at a competent bus garage prior to making an offer, or with the contingency of dissolving the offer it it fails an inspection, and/or requires more than you desire to pay, to have it repaired. Oh.... And all used buses need work (read: $$$$$$$$)! Lotsa' luck! | ||

All of my dirt bikes are wet clutch setups. Also the old D4 I have borrowed from a friend is a wet clutch too. They are meant for long wear in rough / heavy service. I have only driven one bus with a wet clutch, and as John says, it is not a big deal other than making sure you ease it into first as you come to a stop. The wet clutch was a stock setup on the 4905 I belive. Craig - MC7 Oregon | ||

GMC intercity coaches PD4107,PD4108 PD4903,P8M4108A,P8M4905A,H8H649 series coaches all of these coaches have a wet clutch. If they have the 4 speed Spicer transmission. Previous post are correct the clutch operates in oil. | ||

Chris - If you go to the Main BNO page, scroll down the LH menu to "Articles of Interest" and read the one on "Shifting". You should find it helpful. |
