BRAKE APPLICATION GUIDEJAKE BRAKE RETARDERSFOR CATERPILLAR ENGINESCaterpillar Form Number: RENR2327-00How to Use this Guide1.Begin by obtaining engine and vehicle information.This is the first step to selecting brake kits or components. The more information you start with, theless you’ll need to go back to the customer. Gather the following information about the engine andvehicle. Engine modelEngine serial numberEngine horsepower ratingDetermine whether the vehicle has ABS or notDetermine the vehicle electrical system - 12 or 24 volt system, engine or isolated ground (isolatedground systems require dual-lead controls). If the vehicle already has an engine brake model installed, determine the engine brake model todetermine proper parts and service information. Determine whether the vehicle has an automatic transmission. If the vehicle has an auto trans, kitand control group part numbers will not change, but some installation procedures will be differentfrom those for manual transmissions. See Jacobs Service Letters for more information.Note: in a few cases, special situations may apply or additional information may be required. Footnoteswill point out these important cases in this guide.2.Find the information in the correct section of this guide.To select a new brake kit for a vehicle:1. Turn to the Current Applications section of this guide, beginning on page 2, and find the enginemodel and serial number.2. Select the appropriate kit from the base kit columns.3. Select the appropriate engine, cab, and clutch switch controls. “N/R” means a control is notrequired.To determine the correct brake model(s) for an engine:1. Turn to the Service Information section of this guide, beginning on page 5, and find the enginemodel and serial number.2. Any brake model listed under the engine model and serial number may be used on this engine.To determine service information for an engine brake:1. Turn to the Service Information section of this guide, beginning on page 5, and find the enginemodel, serial number, and horsepower for the engine.2. Find the slave piston lash setting and/or trigger valve settings from the appropriate column.To choose a tune-up kit for an engine brake:1. Turn to the Service Information section of this guide, beginning on page 5, and find the enginemodel and serial number, and engine brake model being used on the vehicle.2. Find the appropriate tune-up kit in the Tune-up Kit column.Jacobs Brake is a registered trademarks of Jacobs Vehicle Systems, Inc.P/N 025739 Rev. E1 2004 Jacobs Vehicle Systems, Inc.P/N 33313 Rev.

May not be required if vehicle has controls pre-installed; however, low-resistance gold-contact switches must be usedwith this engine.2Air-to-air-after-cooled engines only. Either Model 349A or Model 346D can be installed on these engines. Model 349A provides up to 30% more retardinghorsepower over Model 346D on these engines.3Clutch Switch Group not required on vehicles with cruise control installed (uses existing clutch switch).4Either Model 336A or Model C336 may be installed on these engines. Model 336A provides up to 35% more retarding horsepower than Model C336. Model336A requires 1/2" push tubes, which are included in kits P/N 148-7451 and 148-7452.5Depending on vehicle configuration, P/N 143-2586 Cab Control Group and P/N 143-6499 Engine Control Group may be required for installation.
