Claims

[Scope of Claim for Utility Model Registration] 1. A threaded rod 1 having male threads 4a, 5a on its outer periphery and screwed into a threaded hole 11 of a cylinder head 6a of an engine at one end threaded portion 4; The nut member 2 has a polygonal outer circumferential surface, a through hole 3b having an inner diameter larger than the diameter of the threads of the male threads 4a and 5a at the base end, and a retainer 14 for the valve springs 15 and 16 at the tip end. A pressing member 3 has a pressing part 3a that presses down the threaded rod 1 in the through hole 3b, and the pressing part 3a of the pressing member 3 has a retainer pin 13 on the engine valve 12. a groove or hole is formed to allow the threaded rod 1 to protrude from the threaded hole 1 of the cylinder head 6a;
1, by screwing the nut member 2 forward, the pressing member 3 pushes the retainer 14 of the valve springs 15, 16 against the urging force of the valve springs 15, 16 at its pressing portion 3a. A tool for replacing an engine valve guide seal, characterized in that the retainer pin 13 is pushed in so that it protrudes from the retainer 14. 2. The male screws 4a, 5a consist of a first threaded portion 4 with a small diameter on one end side and a second threaded portion 5 with a large diameter on the other end side, and a stepped portion 1a is formed between the both threaded portions 4, 5. The engine valve guide seal replacement tool according to claim 1, which is a registered utility model and is screwed into the screw hole 11 of the cylinder head 6a at the first screw portion 4.
