KTA19s

The KTA is the early version of the QSK 19. These engines are very expensive to rebuild or work on. Reman heads from Cummins cost roughly $3000 a piece x 6 = $18,000. A used crankshaft will sell for $8000-9000. The water to air intercooler from a QSK can be retro fitted to the KTA, but expect to pay $6000-7000 for it used. A new set of head bolts is $1800. The internal parts from the QSK will interchange with the KTA.

The KTA were built with different castings as far as the block is concerned. The differences in the block castings make certain blocks worth a considerable amount of money to the sled pullers. The differences is one block will crack, while the other won't crack as easily. Some KTAs were built with aluminum pistons while others had steel pistons. To convert an aluminum piston engine to a steel piston engine is very expensive. If you're going to build power with it, you want steel pistons. The aluminum piston is prone to cracking with big power.

If you think a $20K rebuild for a CAT is expensive then you don't want to know what one of these engines will cost to rebuild.

 

I'd avoid KTA anyway.

 

thanks for this very interesting

quite expensive

maybe it was better idea to build engine from same components but just with more cylinders

here we like modular system so engines share parts

for example mercedes had v6 v8 v10 and v12 engines all build from same parts from 11-22L in last generation and from 9.6-20.9L in older generation

so even for huge v12 engine you will not have larger problems for work on lot of same parts as on smaller ones.....however some parts is hard to find used for example new original mercedes crankshaft cost 5300$

mercedes use this modular system since late 60s when first engines from series 400 appeared for marine and industrial use

 

Use to drive a an ol freightshaker back when my daughter was born in 1988 that had a KT in it with a 13sp and 4:11's, it would pull like a bull for sure, although we hauled a lot over the road I also pulled alot in and out of the mines here in WV and KY.......maybe thats why the frame broke just behind the front axle on the drivers side from the hard pulls she was put in, but anyways like prior post have stated, it is a strong engine, but also a hi-rent engine to work on.
