Abstract

Aspects of the disclosure relate to an engine support system and method. The engine support system includes a frame mounted engine support and at least one engine mounted coupler. The engine support includes a frame mount with a telescoping body and opposing arms to releasably engage a frame of a vehicle, and at least one jack assembly. Each jack assembly includes a collar coupled to and horizontally movable along the telescoping body, and a jack rod coupled to and vertically movable relative to the collar. The jack rod includes a ball mount configured to insert into the coupler at an underside of an engine block of the vehicle. Each jack assembly is configured to support and/or lift the engine block relative to the vehicle frame by vertical movement of the ball mount into the coupler and relative to the frame mount engaged with the vehicle frame.

First claim

What is claimed is:

1. An engine support system for a vehicle, comprising:
a frame mount comprising:
a telescoping body comprising at least one inner sleeve and at least one outer sleeve configured to slide relative to the inner sleeve;
a first arm at a first end of the telescoping body configured to releasably engage a first side of a frame of a vehicle; and
a second arm at a second end of the telescoping body opposite the first end configured to releasably engage a second side of the vehicle frame;

a first coupler configured to attach to an engine of the vehicle; and
a first jack assembly, comprising:
a first collar slidably coupled to the telescoping body and configured to move horizontally along the telescoping body; and
a first jack rod coupled to the first collar and configured to move vertically relative to the first collar, the first jack rod comprising a body and a ball mount at an end of the body, the ball mount configured to insert into the first coupler at an underside of an engine block of the vehicle.

2. The engine support system of claim 1 , further comprising the first coupler configured to removably attach to the underside of the engine block of the vehicle.

3. The engine support system of claim 1 , wherein the first coupler is configured to removably attach to threaded holes configured to mount an oil drip pan to the underside of the engine block of the vehicle.

4. The engine support system of claim 1 , wherein the first coupler includes a receptacle defining a through hole configured to receive a fastener to removably attach the first coupler to a single threaded hole at the underside of the engine block of the vehicle.

5. The engine support system of claim 1 , wherein the first coupler includes a receptacle fixedly attached to a plate with a plurality of through holes, at least two of the plurality of through holes configured to align with at least two threaded holes at the underside of the engine block of the vehicle.

6. The engine support system of claim 1 , wherein the at least one inner sleeve and the at least one outer sleeve each comprise a non-circular cross-section.

7. The engine support system of claim 1 , wherein the telescoping body comprises a first inner sleeve fixedly attached to the first arm and a second inner sleeve fixedly attached to the second arm.

8. The engine support system of claim 1 , wherein the first arm comprises a first flange configured to engage a first upper surface of a first rail of the vehicle frame and the second arm comprises a second flange configured to engage a second upper surface of a second rail of the vehicle frame.

9. The engine support system of claim 8 ,
wherein a first edge of the first flange of the first arm is tapered to increase a contact surface area with the first rail angled relative to a center axis of the vehicle; and
wherein a second edge of the second flange of the second arm is tapered to increase a contact surface area with the second rail angled relative to the center axis of the vehicle.

10. The engine support system of claim 8 , wherein the frame mount further comprises:
a first clamping jaw removably attached to the first arm, the first clamping jaw comprising a first bracket and a first clamping bolt, the first bracket defining a first threaded hole, the first clamping bolt positioned in the first threaded hole and configured to move relative thereto to clamp a portion of the first rail between the first flange and the first clamping bolt; and
a second clamping jaw removably attached to the second arm, the second clamping jaw comprising a second bracket and a second clamping bolt, the second bracket defining a second threaded hole, the second clamping bolt positioned in the second threaded hole and configured to move relative thereto to clamp a portion of the second rail between the second flange and the second clamping bolt.

11. The engine support system of claim 1 , wherein the first jack assembly is configured to lift the engine block of the vehicle relative to the vehicle frame by vertical movement of the jack rod relative to the frame mount engaged with the vehicle frame with the ball mount in the first coupler.

12. The engine support system of claim 11 , wherein the first jack assembly further comprises a first threaded cuff fixedly attached to an outer surface of the first collar and offset from a center of the first collar along a center axis of the first collar.

13. The engine support system of claim 1 , wherein the body of the first jack rod is threaded.

14. The engine support system of claim 13 , wherein the first jack assembly further comprises a first threaded cuff attached to the first collar, the first jack rod positioned within the threaded cuff.

15. The engine support system of claim 1 , wherein the first collar comprises a non-circular cross-section.

16. The engine support system of claim 1 ,
wherein the first jack assembly is configured to engage the first coupler at a first side of the engine block of the vehicle;
wherein the engine support system further comprises a second jack assembly configured to engage a second coupler at a second side of the engine block of the vehicle, comprising:
a second collar slidably coupled to the telescoping body and configured to move horizontally along the telescoping body; and
a second jack rod threadably coupled to the second collar and configured to move vertically relative to the second collar, the second jack rod comprising a second body and a second ball mount at an end of the second body, the second ball mount configured to insert into the second coupler at the underside of the engine block of the vehicle.

17. A method of supporting an engine of a vehicle, comprising:
suspending a frame mount of an engine support system across a frame of a vehicle beneath an engine block of the vehicle by moving a first arm attached to a first end of a telescoping body relative to a second arm attached to a second end of the telescoping body to an engaged orientation;
horizontally sliding a first collar of a first jack assembly of the engine support system along the telescoping body to align a ball mount of a first jack rod of the first jack assembly with a first coupler at an underside of the engine block of the vehicle; and
supporting an engine of the vehicle relative to the vehicle frame by vertically moving the first jack rod of the first jack assembly to insert the ball mount of the first jack rod of the first jack assembly into the first coupler at the underside of the engine block.

18. The method of claim 17 , further comprising lifting an engine of the vehicle relative to the vehicle frame by continued vertical movement of the first jack rod of the first jack assembly.

19. The method of claim 17 , further comprising attaching the first coupler to the underside of the engine block of the vehicle.

20. The method of claim 17 , further comprising:
attaching a first clamping jaw to the first arm to position a portion of a first rail of the vehicle frame between a flange of the first arm and a first bracket of the first clamping jaw; and
rotating a first clamping bolt in a first threaded hole of the first bracket of the first clamping jaw to clamp the portion of the first rail of the vehicle frame between the first flange and the first clamping bolt.
