Warranty StatementThe information in this document has no effect on present warranty coverage or repair practices, nor does it authorize TRP or Campaign actions.

ContentsThis Service Parts Topic updates and replaces previous information in 95T110 on the TriTech™ series of pistons, rings and cylinder kits for NH and NTengines. The recommended piston for certain high horsepower NT industrial generator set engines has been changed so the 95T110 is no longercorrect thus copies of 95T110 must be discarded. Certification Field Fix (FF208) is released for emissions controlled NH and NT engines using thenew TriTech™ pistons. This updated information replaces the recommendations of any prior Service Parts Topics.

TriTech™ Cylinder Kits utilize technology gains from our 1991 and 1994 engine development experience to provide significant reliability and durabilityadvances for earlier Small Cam, Big Cam, and 88 NH and NT engines.

The most prominent feature of the TriTech™ Kits is their use of three piston rings rather than the four rings used on most NH and NTs of the past. TheTriTech™ compression rings keystone angle and matching piston ring groove angles are 15 degrees compared to 20 degrees on the four ring stylepistons improving durability but making rings noninterchangeable. Recent emissions regulations on new engines have driven oil consumption levelsdownward in order to meet stricter particulate matter limits. The TriTech™ Cylinder Kits now offer similar excellent oil control for earlier model NH andNY 855 cubic inch engines at rebuild time. Improved oil control means reduced oil consumption along with a reduction in hard carbon buildup therebyreducing wear and improving durability.

CAUTION

Do not mix the rings among NT three ring and four ring sets, only the bottom oil control rings are interchangeable.

The TriTech™ Cylinder Kits are offered at two performance levels, TriTech™ and TriTech™ Plus. The new kits cover both the single and dual niresistpiston product lines. Most 855 cubic inch NH and NT and N14 engine models will have at least two cylinder kit options to choose from, TriTech™ orTriTech™ Plus. Some engine models will have three cylinder kit options, TriTech™ or TriTech™ Plus with single niresist piston and TriTech™ Plus withdual noresist pistons.

CAUTION

All pistons used within a given engine must be the same weight to avoid rough running due to component imbalance. The new TriTech™ 3 ringpistons are the same weight as the 4 ring piston they directly supersede. However, some older pistons two and three steps backward in thesupersession chain are not the same weight and must not be mixed within an engine. Consult Table 2 when replacing less than a full set of sixpistons to be sure mixing of new and older piston part numbers is acceptable.

TriTech™ Single NiResist Cylinder Kits are designed for those engines that are primarily operated at higher speeds (2,100 rpm), seldom highly loadedat lower engine speeds. TriTech™ Cylinder Kits include the TriTech™ ring set, Part No. 3803990 which contains an inlaid chrome top ring, a ductile ironsecond ring, and a chrome faced "I" oil control ring.

TriTech™ Plus Single NiResist Cylinder Kits are recommended for Formula and highly loaded prebig cam IV engines operated mainly at 1,800 rpm orhigher engine speeds, or those equipped with compression brakes. TriTech™ Plus Single NiResist Cylinder Kits contain a piston designed for moresevere service. These kits also include a severe duty TriTech™ Plus ring set, Part No. 3803358 which contain s a heavy inlaid chrome top ring, achrome faced second ring, and a heavy chrome faced oil control ring.

TriTech™ Dual NiResist Cylinder Kits are designed for those engines that were originally built with dual niresist pistons. These cylinder kits are forengines primarily operated at 1,600 rpm or higher, seldom fully loaded at lower engine speeds. TriTech™ Dual NiResist Cylinder Kits include theTriTech™ ring set, Part No. 3803990 which contains an inlaid chrome top ring, a non faced second ring, and a chrome faced I oil control ring.

CAUTION

Use a Dual NiResist pistons only in engiens that are both aftercooled and piston cooled. Use of Dual NiResist pistons in nonaftercooled or nonpiston cooled engine will result in severe damage.

TriTech™ Plus Dual NiResist Cylinder Kits are designed for those engines that are worked hard, often fully loaded at all engine speeds, and with heavyuse of compression brakes. TriTech™ Plus Dual NiResist Pistons are recommended as replacement for Single NiResist Pistons in engines which haveexperienced heavy second ring groove wear. The TriTech™ Plus Dual NiResist Piston is designed for severe duty by incorporating several uniquefeatures, most visible being the anodized crown material for improved high temperature durability. These cylinder kits also include a severe dutyTriTech™ Plus Ring Set, Part No. 3803358 which contains a heavy inlaid chrome top ring, a chrome faced second ring, and a heavy chrome faced I oilcontrol ring.

TriTech™ Cylinder Kits are available with both the standard sized Lower Press Fit (LPF) liner, Part No. (3055099), and the 0.51/10.2 mm [0.020/0.040inch] oversized LPF cylinder liner, Part No. (3065405). The standard LPF liner, Part No. (3055099) is recommended for cylinder blocks originallymachined after September, 1986 or blocks reconditioned to new dimensions for standard LPF liners. The 0.51/1.02 mm [0.020/0.040 inch] LPF liner,Part No. (3065405) is recommended for those blocks that were not originally machined for the LPF feature and for blocks where counterbore wear issuch that the standard liner will no longer fit properly. The appropriate sealing ring shim (See Table 7) must be used with these liners to obtain properprotrusion.

Cylinder kits containing 1.02 mm [0.040 inch] oversized LPF liner, Part No. (3054936) and 0.51 mm [0.020 inch] oversized Upper Press Fit (UPF) liners,Part No. (3046325) are no longer offered. The liner, Part No. (3054936) has been replaced with the 0.51/1.02 mm [0.020/0.040 inch] LPF liner, Part No.(3065405). The 0.51 mm [0.020 inch] oversized UPF liner, Part No. (3046325_ will only be available in liner kit, Part No. 3801387, and is onlyrecommended as a direct replacement for a liner, Part No. 3046325. If block counterbore machining is required, the block must be machined to accepteither the standard LPF, Part No. (3055099) or 0.51/1.02 mm [ 0.020/0.040 inch] oversized LPF, Part No. (3065405) along with the appropriate sealingring shim.

NOTE: If the block counterbore area must be salvaged with a sleeve, use one of the four salvage sleeves listed in Table 8 designed to workwith the LPF feature. Use of these sleeves will bring block back to standard dimensions for use with standard LPF liner, Part No. (3055099).

Table 1 lists all NH and NT and N14 855 engine Control Parts List (CPL) numbers along with the appropriate TriTech™ piston, standard and oversizedLPF cylinder kit part numbers. All engines manufactured after January 1973 used a CPL number and Table 1 must be used for correct piston and kitselection for these engines.

Certification Field Fix (FF208) applies to those CPL numbers followed by the letter (A) in Table 1. When rebuilding these engines with the newTriTech™ pistons, the engine dataplate must be stamped with "FF208".

Table 2 is an old piston to TriTech™ piston cross reference to be used only when the CPL number is not known.

Table 3 lists old piston kits and the appropriate replacement TriTec™ piston kits.

Table 4 cross references old cylinder kits to the new TriTech™ Cylinder Kits, including both standard and oversized kits.

Table 5 shows the various new TriTech™ pistons, their compression ratios, and appropriate piston and cylinder kits.

Table 6 shows the contents of the new TriTech™ Piston Ring Sets.

Table 7 lists the sealing ring shims for both standard and oversized liners.

Table 8 lists the various counterbore upper deck repair sleeves.

Table 9 lists various TriTech™ Cylinder Kits to TriTech™ Overhaul Kits.
