5 Speed STD GEARBOX failure
Posted: Sat Jul 16, 2022 5:34 am
I am relatively new to this forum but I would like to find out if anyone in this sphere, has ever experienced this type of failure on a
1965-1970 Datsun Sports 1600/2000 2000 Transmission Case (5-Speed)
4 Pictures of GB / crack. I hope thse are able to be viewd.
The unit came from an unknown source but looked fine when purchased. it was overhauled but no special treatment given - its STD.
The Assy – Extension< Rear 32130-25500, was refurbished in 2015/6 by an Aust. / Victorian / Datsun Fairlady enthusiast. Verbal advice offered was that it had some alterations carried out on it to improve it.
It was attached to the remaining gearbox portions (which was used and good working order) in 2018 and felt very tight and responsive.
The race car has a competition tail-shaft which has been used since 2012.
July 2022, when inspecting the extension and its parts, due to the failure, it was found that all parts used in, Assy – Extension< Rear 32130-25500, were standard. The pins had worn high into the ARM-CONTROL 32844-25500.
The gearbox mount, is a refurbished nolathane type, purchased in and used in the race car since 2009. The engine mounts are made from the same material and all are still in excellent condition and there are no visible separation from the metal brackets.
The gearbox has been used in a race car since March 2018 and has raced some 65 hours.
During those times the engine has been refreshed twice. [img2][/img2]
