Located a 6V92 engine now installed in a "hoe" construction equipment. Owner wants a cummins. Will the bell housing & flywheel from my 6V71 fit a '92? Pros & Cons Thanks C Ray | ||

From what I've read, there are two different rotations. Make sure the motor spins in the right direction! The 6v92 will obviously have more power than the 6v71. As a car guy, "there's no replacement for displacement", so putting more cubic inches in never hurts.  Of course, I'll say that with the personal experience of cracking my firewall and tweeking the body by putting too much power into a 3rd gen F-body, but hell did it move. Screwing up the body doesn't hurt as much when the body was only $300. I found these old threads on this, which answer most of the conversion question... http://www.busnut.com/bbs/messages/233/3712.html?1050608555 http://www.busnut.com/bbs/messages/233/5223.html?1073324667 It'll bolt up to the bell housing, but you'll run into a maching issue, so be prepared for a little extra work. As always, consult Google, and talk to whoever is going to help you. Talking to someone who's done it is always helpful. http://www.google.com/search?q=6v71+to+6v92+engine+swap | ||

I would be very leery of this deal-- first of all, why would someone replace an engine unless it was worn out? Second of all, the engine in a hoe is going to be set up as an industrial engine, not a highway vehicle engine, so other than the basic parts it will need a few changes to work in a bus. Like JW says-- check the rotation also, you need a RH engine. Finally, the flywheel housing off your 6V71 will not fit the 92. Keep looking! --Geoff '82 RTS AZ | ||

Another thought would be the difference in governors. OTR equipment uses a limiting speed gov. and marine and some construction equip. uses the variable speed gov. Unfortunately you can't use one on the other. Bob | ||

Although Detroit did use some limiting speed governors on some early 671N's and 8V71's in Marine applications they didn't work out too well because the limiting speed governor only gives the operator control over the engine at intermediate ranges while the variable gives the operator complete control over the entire speed range. Thought I'd better clarify that before FF jumps in and corrects me. He's one intelligent guy! | ||

You gonna have enough radiator to cool that big thing? I don't know, but it's one more thing to think about. Casper4104 | ||

If your bus model originally offered a 6?V92 you'll be ahead of the curve if you locate a donor bus to get all the 6V92 accessories you need. Oil cooler, drivehshaft may be different, motor mounts, induction and location of the turbo and exhaust. Is there room in your engine compartment for the turbo plumbing? You'll be essentially stripping your stationary engine down to a long block and replacing all of the ancilliary bits with bus components. Will your transmission handle the 6V92s torque? The thing about cooling ain't no joke either. You may need a radiator for your bus that will handle the heat created by a 6V92T. If the engine isn't a turbo engine (some equipment V92 powerplants were built without turbos), you won't gain enough to make the swap worthwhile. If you have a "V" drive and 2 stroke, you have a LH engine. The construction equipment is likely RH rotation. A "T" drive (engine perpendicular to the drive axle) would be RH rotation. Trying to change the rotation of a DD is a nightmare. What bus do you have? Whatever bus you have, repowering with a different engine will be a large job...but, doable. Do your research carefully! Good Luck, JR | ||

I have a MCI 5C. Am aware of the cooling & relocating the turbo. Did not know about the governor & other items mentioned. Thanks guys, C Ray |
