Gary,

This is going by memory so consider the answer as close, but not precise.

Very early 90’s for the first H3 conversions. I do not know when the first H3 seated were introduced.

The Series 60 was a 94/95 introduction and the first on conversions I believe was in the 45 foot XL with the Allison 5 speed. When the World transmission (our current 6 speed) became available all XL coaches were fitted with the Series 60. The five speed transmission was too long to be used with the Series 60 in 40 foot coaches, but the 6 speed was shorter and that allowed the combination to be used in all coaches.

If Prevost is on board maybe someone there can answer.

Thanks Jon The reason I ask is a lady I met here at the park just bought a H and I believe it to be a forty foot, she was asking some questions as she had experienced some problems with electrical components of her coach Since she is a single lady and is a full timer I will steer her to this site and pog for answers to her questions. This is probably on the wrong heading maybe the admin can put it where it needs to be Thanks

Early 90’sas far as my knowledge of H series goes. 8-V92’s were avaliable from Detroit in both configurations thru at least 2000. The tag axle configuration for the 60 series was not until at leat 92 in the xl because I have a friend trying to put a 60 in his 91. that is the limit of my brain. my 98 is 60 series. Bob

Interesting, I had an 94 with a 93 shell and Prevost told me that was the last of the 8V’s. They switched over to the series 60 and early ones had the 5 speed like Jon said.

just ran a serial # last week showed 99 model . My brain said impossible. Was corrected to find out Detroit built the engine thru 2000 in both mechanical and even DDEC IV. My lesson of the day. Was in a friends 92 Prevost he needed help on and it is mechanical not DDEC. go figure. Bob

Perhaps that 1999 8V92 was originally built for the military or emergency equipment which will never be licensed such as airport fire fighting trucks?

Some way this engine found it’s way into a 91 xl in the correct configuration for a bus engine. I understand that replacement/new engine were available until 2000 in any configuration. Military is still in production :: Mil spec and still in use. You know the military is exempt from everything and slow to change. We could invite the 2 stroke YODA– Don to join :: at this time I’m sure he has much more on his plate than time though. Might have to just defer to asking him questions. Don services the Bus and Boating industry 2 stroke needs.Makes them compliant to epa requirements. Plus does some amazing mods. Bob

At the risk of repeating information and even being off in my information I hazard and answer.

The first H3 models came out in 89. The H3-40 and 45. They had 8V-92 engines until 94 when the Series 60 came available. At that time the designation became H3-41 and 45. The 60 was longer and required and bit more chassis length.

There were relatively few VIP versions of the H3-40 and no 41s ever made it out of the factory as VIP…….or so I have been told.
