Installation Guides

Welcome to the Engines & Transmission TAN installation resource center. These guides provide essential information for installing your crate engine, transmission, or outboard motor. Important: These are general guidelines. Always consult your vehicle’s factory service manual and the specific instructions included with your product.

⚠️ Safety First: Engine and transmission installation involves heavy components, flammable fluids, and complex systems. Use proper safety equipment, adequate lifting tools, and seek professional assistance if you are uncertain about any step.


Crate Engine Installation Guide

Pre-Installation Checklist

Before beginning your crate engine installation, verify the following:

Item Status
Engine matches vehicle application (motor mounts, oil pan, accessories)
All necessary gaskets, seals, and fasteners are on hand
Cooling system is compatible (radiator capacity, hoses)
Fuel system matches (carbureted vs. EFI, fuel pressure)
Exhaust system fits cylinder heads and chassis
Wiring harness and ECU are correct for engine
Transmission is compatible with engine and vehicle
Proper lifting equipment (engine hoist, load leveler) available

Step 1: Remove Existing Engine

  1. Disconnect battery (negative terminal first)

  2. Drain fluids: Coolant, engine oil, transmission fluid

  3. Remove components:

    • Air intake and air filter housing

    • Radiator and cooling hoses

    • Exhaust manifolds or headers

    • Fuel lines (depressurize EFI systems first)

    • Electrical connections (label all wires for reinstallation)

    • Drive belts and accessories

    • Engine mounts and transmission bellhousing bolts

  4. Attach engine hoist to factory lift points or secure chain locations

  5. Remove engine carefully, ensuring transmission and accessories clear the engine bay


Step 2: Prepare New Crate Engine

Task Details
Remove shipping materials Remove all protective covers, shipping brackets, and plastic wrap
Install oil drain plug Apply thread sealant if required; torque to specification
Prime oil system Use a priming tool with a drill to circulate oil before first start
Install spark plugs Apply anti-seize to threads; torque to spec
Install intake manifold If not pre-installed, use new gaskets and follow torque sequence
Install valve covers Use new gaskets; torque evenly
Install oil filter Pre-fill with oil; hand-tighten plus 3/4 turn
Install water pump and pulleys If not pre-installed; use thread sealant on bolts entering water jackets
Install flywheel or flexplate Use new bolts with thread locker; torque to spec
Install clutch and pressure plate (manual) Align with alignment tool; torque pressure plate bolts evenly

Step 3: Install New Engine

  1. Position engine over engine bay using load leveler for angle adjustment

  2. Align motor mounts and lower engine onto mounts

  3. Install motor mount nuts/bolts but do not fully tighten

  4. Connect transmission:

    • Automatic: Guide torque converter into flexplate; ensure converter is fully seated

    • Manual: Align transmission input shaft with clutch disc; use alignment tool

  5. Install bellhousing bolts and torque to specification

  6. Install torque converter bolts (automatic) and torque to spec


Step 4: Connect Systems

System Installation Steps
Fuel System Install fuel lines; check for leaks; prime EFI system before starting
Cooling System Install radiator, hoses, and heater lines; fill with proper coolant mixture; burp cooling system
Electrical Connect main engine harness; install battery cables; verify starter connections; connect sensors
Exhaust Install headers or manifolds with new gaskets; torque bolts in sequence
Accessories Install alternator, power steering pump, A/C compressor; install drive belts; tension properly
Intake & Air Install air intake; connect MAF sensor; verify throttle linkage operation
Fluids Fill engine oil; fill transmission fluid; fill power steering fluid; fill coolant

Step 5: First Start Procedure

⚠️ Critical: Proper break-in is essential for engine longevity.

Before Starting:

  1. Double-check all fluid levels (oil, coolant, transmission, power steering)

  2. Verify no loose tools or debris in engine bay

  3. Prime fuel system (cycle key on/off to build pressure in EFI systems)

  4. Disable ignition (pull fuel pump fuse or distributor wire)

  5. Crank engine for 10-15 seconds to build oil pressure

  6. Re-enable ignition and fuel system

Initial Start:

  1. Start engine and immediately bring to 2,000–2,500 RPM

  2. Maintain 2,000–2,500 RPM for 20-30 minutes for flat-tappet cam break-in

    • Roller cam engines have shorter break-in requirements, but varying RPM is still beneficial

  3. Check for leaks during break-in (oil, coolant, fuel)

  4. Monitor gauges: Oil pressure, coolant temperature, voltage

After Break-In:

  1. Change engine oil and filter (first oil change at 500 miles or after break-in)

  2. Inspect for metal particles in drained oil

  3. Re-torque intake manifold and valve covers after heat cycle

  4. Check all fasteners after first drive


Transmission Installation Guide

Automatic Transmission

Pre-Installation:

  • Ensure torque converter is fully seated (should hear 2-3 clicks)

  • Verify flexplate is properly installed and undamaged

  • Confirm transmission cooler lines are clean and unobstructed

Installation Steps:

Step Details
1. Position transmission Lift transmission onto jack; secure with strap
2. Guide torque converter Align converter with flexplate; converter should spin freely before bolting
3. Raise transmission Align with engine; ensure dowel pins engage
4. Install bellhousing bolts Torque in sequence: 30-40 lb-ft (GM), 40-50 lb-ft (Ford)
5. Install torque converter bolts Torque to 35-45 lb-ft; rotate flexplate to access all bolts
6. Install transmission mount Do not fully tighten until exhaust and driveshaft are installed
7. Install driveshaft Use new U-joints if needed; mark orientation before removal
8. Connect shift linkage Verify correct adjustment; test all gear positions
9. Connect cooler lines Use new seals; verify flow direction
10. Fill with fluid Use correct fluid type; add 4-5 quarts initially, then start engine and add remaining

Manual Transmission

Pre-Installation:

  • Inspect pilot bearing/bushing in crankshaft; replace if worn

  • Verify clutch disc is properly aligned

  • Inspect flywheel surface; resurface if needed

Installation Steps:

Step Details
1. Install flywheel Use new bolts with thread locker; torque to specification
2. Install clutch disc and pressure plate Use alignment tool; torque pressure plate bolts evenly in a star pattern
3. Position transmission Use transmission jack; ensure input shaft is aligned with clutch
4. Slide transmission forward Rotate output shaft slightly if input shaft splines don’t align; do not use bolts to pull transmission
5. Install bellhousing bolts Torque to specification; tighten evenly
6. Install slave cylinder If hydraulic, bleed system thoroughly
7. Install shift linkage Adjust to factory specifications
8. Install driveshaft Ensure proper slip yoke engagement
9. Fill with fluid Use correct manual transmission fluid (ATF, gear oil, or synthetic)

Outboard Motor Installation Guide

Transom Mount Outboard

Pre-Installation Requirements:

  • Transom thickness: 1.5–2.5 inches typical; must be solid with no rot or cracks

  • Transom height: Match motor shaft length (15″ short, 20″ long, 25″ extra-long)

  • Boat capacity: Verify boat is rated for motor horsepower and weight

Installation Steps:

Step Details
1. Position motor Center motor on transom; use lifting eye with appropriate hoist
2. Adjust mounting height Anti-ventilation plate should be even with or slightly above boat bottom
3. Mark and drill holes Pilot drill; use stainless steel hardware with backing plate
4. Install mounting bolts Use marine sealant around bolt holes; torque to specification
5. Connect steering Attach steering cable; verify full range of motion
6. Connect controls Shift and throttle cables; adjust to factory specs
