Removing the SRF Engine and Transaxle

Background
We’ve done A LOT of engine and transaxle swaps over the years.  It seems most of them were done at the track (and in 100 degree heat).  Over the years we’ve gotten it down to a less-than 3 hour process.  Here’s how we do it.
Engine Change Only
  1. Remove the left-rear axle nut.
  2. Put rear of car on blocks.
  3. Remove the rear wheels.
  4. Disconnect the negative battery terminal.
  5. Remove right front radiator hose to drain. (Note, unscrew the expansion tank cap after the hose is disconnected to drain all the water).
  6. Remove the air box as a unit, complete with mounting bracket and hoses.
  7. Remove the throttle cable from throttle body and put in the right-rear wheel area.
  8. Remove the bolt or pin from alternator adjuster.
  9. Remove the large pulley from crankshaft (this makes pulling the engine out easier).
  10. Remove the large alternator bolt and lay alternator with wires attached on right side bodywork.
  11. Remove the expansion tank and ½" hose to water manifold.
  12. Remove the tailpipes from the exhaust header. Leave the header on the motor.
  13. Remove the starter and disconnect wires from block, senders and all rear electric’s.
  14. Cut wire ties holding wires and hoses to the frame.
  15. Disconnect the oil cooler lines and fuel lines from engine and pull to right side of car where wheel used to be. Note, capping these hoses with AN caps is a nice touch.
  16. Disconnect the large shifter bolt which connects the shift linkage u-joint to the transaxle.
  17. Disconnect the coolant hoses from right and left side of engine.
  18. Drop the left-rear LCA from the LBJ pin and pull axle out of left rear knuckle.
  19. Attach engine sling and hoist.
  20. Remove upper right-rear motor mount.
  21. Be sure that you do not drop the motor or transaxle on the fuel pump connections as this can break the pump (expensive). You could remove the pump for safety if it looks like it could hit. We have broken a pump this way!
  22. Loosen the left-rear transaxle mount (this has to eventually come off transaxle and frame and note the way it comes out.)
  23. Loosen the right-front motor mount.
  24. Remove all transaxle to engine mount bolts (be sure you get the ones on the front and bottom). There should be 7 bolts total.
  25. Remove bolts from left-upper transaxle mount and push the mount up into space between the brake line and frame.
  26. Remove the left-lower transaxle mount and then the right-front motor mount bolt which you previously loosened.
  27. The engine should now separate from the transaxle. Pull the transaxle to the left side of the frame to separate the motor/transaxle as you lift the motor.
  28. Rotate the motor slightly to clear the header. Watch out that you don’t catch the master switch wires and the fire extinguisher nozzle.
  29. Reverse the procedure except the transaxle to engine bolts are installed before the mount bolts. The left-rear transaxle mount should go on the transaxle first and then install the other mounts.

  18. Drop left-rear and right-rear LCA’s from the LBJ pin’s and pull axles out of left and right rear knuckles.
  19. Remove the axles from the transaxle. The axles are held in the transaxle by a compression ring. The axles will pop out if you can "snap-pull" them. We have CAREFULLY used a large screwdriver to wedge them out. There is a tool with a sliding weight used at auto shops to remove the axles, but you should be able to pop them out without it. Regardless, there is a very real chance you will damage the axle seals, so you should have two on hand as replacements before you start.
  20. Attach engine sling and hoist.
  21. Remove upper right-rear motor mount.
  22. Be sure that you do not drop the motor or transaxle on the fuel pump connections as this can break the pump (expensive). You could remove the pump for safety if it looks like it could hit. We have broken a pump this way!
