Push Rod Tube (40HP)
These should be expanded prior to installation, so they put outward pressure on the seals for a dry engine. ONLY use Genuine Silicone Push rod Tube Seals for longest leak-free life.
Be sure to install these with the welded seam "UP".
You can also use these 40hp tubes on 1600cc based engines that are narrower than stock due to fly cutting and more compression since 40hp tubes are shorter than 1300-1600cc tubes!
