Cost of inframe overhaul for 8V71, 8V92 and 6V92.

[JohnEd]

Can anyone quote the approx costs for these engines?  Is Don still alive?  Anybody else have numbers.  I once heard $13K (worst case) for a 8 V 71.

Maybe some of you could share what you paid.

Thanks,

John

Last winter I had a 8v92 in my dump truck done ( inframe) The cost was around 5000 dollars, I had one new head and a used head and a good blower, So the cost would have been much more if I would not have had these parts. What I got for the 5000 was a piston and liner kits, new rod and mains, gaskets, Installing new valve and ect in the head and going over the other head cking injectors and what ever they needed maybe a coupl of new ones and labor. Maybe some other little things. Working good.

I have a friend of mine up here who is a 25 year 2 stroke guy from detroit shop in next town over now retired. I pulled the motor. I paid 1600 for out of frame kit. Paid him 1500 hundred. I didnt have to have any machine work done everything was in specs. So it was 3100.00 for me. But I did the R&R

  These two jobs above, was this DD genuine parts, or Chinese? IIRC, Luke at US Coach said about $200 a hole for a DD genuine liner piston set, plus gaskets, bearings, head work, you would be over $2K in parts. Ive seen China kits at $148 per hole which is why im asking.

  Not saying the Chinese stuff is bad stuff, just not anything I would ever want to put into my motor. US, Mex, SA, Taiwan, S Korea, but not China, sorry. 

  The more work you can do yourself, the more labor you save. Just take pics and keep reciepts

No mine were not DD parts. But they are made in USA by Federal Mogual

  Cool. Wonder if FM is OEM to DD.

[papatony]

   If FM isn't oem there about the best you can get. I did an in frame replaced every thing,rebuilt the blower, rebuilt cams for about 7,000. A friend did all of the rebuild for me or it would have about 2 grand more.

that must of been with new heads , injectors everything new. Best price I found was www.agkits.com

Chart,

FP kit lists for 1395 for all 8 cylinders and a bearing set plus.  That is $170 per cylinder with all the parts and gaskets.  Federal Mogul is supposed to be the equal of DD and FM gives a 2 year warranty.

Thank you and the others for the information.  With a contact like your neighbor I feel more secure about this adventure.  I have friends over on the coast that have a retired 2 stroke guy take of their 4905 and they are delighted.  Friends and contacts, never fails no matter the racket.

Thanks again,

John

John,

Just got an inframe a couple months ago, all said and done around $5k. Rebuild kit was $1375, Interstate-McBee brand, made in Taiwan. I also took both heads to another shop and had them rebuilt. I believe the price DD quoted me per hole was closer to $250 per.

This is what was included in my kit,
In-Frame Kit:

8 x Liner Kits (Includes set of crevice seals)

8 x Piston Crown

8 x Piston Skirt

8 x Piston Ring-Sets

8 x Piston Pin

16 x Piston Pin Bolts

16 x Spacers

8 x Piston Pin Slipper Bearings

1 x Head Gasket Set

1 x Main Bearing Set (Std.)

1 x Rod Bearing Set (Std.)

1 x Thrust Washer Set

1 x Rocker Cover Gasket

1 x Oil Pan Gasket


So far, so good, 50 psi oil pressure at 1800 rpms.

Clevite has one of the best kits that is the one I use for after market a 6v92 kit is around 2000 bucks FP and FM are the same outfit you never know where they made,don't forget Don he has good engines kits for clean engines.
I am watching this one so many variations on what you guys are calling a in frame, been awhile since Luke bought liners at DD lol I have 8 for a 8v92 485.00 each last week, I ran across a special on 71 liners and piston for 25 bucks each new but found out they were military the guy was trying to pawn those off as turbo pistons and liners for a 71 series


good luck

Can an 6V92/8V92/8V71 really be inframed inside the bus like they do on semi tractors and other trucks?

I suspect I could find someone to inframe my Series 60 in the bus since the valve cover comes off from inside the bus, but I expect the extra labor might pay to just remove the engine from the bus.

[luvrbus]

They can Brian but to me it is a lot easier just to roll the engine out it is a bitch trying to install the heads and keeping the oring gaskets in place on a 2 stroke  on a Eagle on the right side 2 hrs the engine is out where you can get at it.
Dealer do not like to roll the engine out as one told me if the transmission, clutch or anything goes later they get the blame because they had it out with the engine lol so that is why dealers spend more time doing it in the bus 


good luck

[belfert]

Inframing an engine is probably one place where spending more on a better inframe kit is probably a good idea.  Do you really want to be replacing a broekn part of the internals of your engine.  An extra $500 or whatever would seem cheeap if one had to pay twice for labor.

A good shop will warranty the labor if they supply the inframe kit, but not all shops will do so.  Even if you can get free labor do you really want a blown engine to ruin your trip?

[bevans6]

Don't forget that if you in-frame you can't replace or inspect the rear seals, the pilot bearing, the throwout bearing (assuming a manual trans).  All three were bad or about to be bad soon on my engine.
