"You're better off with the 8 71, the 6 92ta is not as reliable or rugged"
My mechanic, who has been at Portland's largest charter bus company for over 20 years, made this statement a couple of week ago, when I was thinking outloud about put'n the 6 92 in my 4108.Can anybody shed some light or comment?
He says we should try to stuff a DD series 50 in there. I wonder if we could get one to turn to the left and hook to a v730 allison. That would be fun. |

Just how many miles are you thinking of putting on the 6v92? At 12k per year engine life should be 30 years if it lasts 360,000 miles instead of the 400k+ that an 8v71 is expected to go! That'll outlast me. The 8v92 is another story since they tend to throw connecting rods at 250,000 miles if the bearings aren't changed at the 200k mark. The company I drive for commercially has 30 6v92's and love them and have no unusual problems with them.

Jim is right, any fresh 6V92 with reasonable care should more than last for the life of the conversion. New bottom end bearings are not that big a deal, if it makes you feel better after a 100,000 miles or so.
The early Series 50 transit engines did indeed turn left hand but they had serious bottom end oiling problems so Allison developed the VR731 which has an extra input gear to reverse the rotation. All transits you would probably run into with a Series 50 would also have this transmission. Get the package.
Remember you are talking electronic control engine and transmission and this can add thousands of dollars to the conversion process. This should be a great drive train, properly geared. FWIW.

Jim is right about the Series 50 with the VR731 but Allison has had a ton of trouble with the input shaft on that unit. While I'm on here has any one seen the 4106 that they put a 903 Cummins in, that is on this web site . I was wondering how they did it , they say the used a v730 as far as I know Cummins never made a left handed 903. |

Cummins made a LH 903. Was used in a few FLX and American General Transits.
I say it in George Lowery's 4106. |

Actually Citizens Area Transit in Las Vegas < Nevada is repowering almost 1/2 the fleet to series 50 Detroit's with Allison V731's. The power difference is amazing. There is the need of a reverser needed. Most of the Repower Conversions are being completed by Complete Coach Works in California, however the blood, sweat and tears of the design came out of Williams Detroit Diesel/ Allison in Las Vegas. |
