Re: Gear lever housing bolts
Parts List says bolts are 5/16" 18tpi (ie UNC) with 7/8" hex head. Can't help with the length thoughGERRY wrote:would any one know which is the right thread and length of bolt for the gear shifter plate,

Re: bolts for gear sticks
Hi,
7/8" might be the length. They take a 1/2" wrench.

I think Les might be right - 7/8" head would be rather large!Lesfen wrote:7/8" might be the length. They take a 1/2" wrench.

Re: bolts for gear sticks
As a general rule you will find that  bolts which screw into castings on the Dextas  are UNC, whilst studs are UNC at one end and UNF at the other.  In other words tapped holes in casting are invariably UNC.  
As many of the tapped holes in the castings are "blind" it is essential that the correct length of bolt or stud is used. If they are too long it is possible that the casting will be damaged and in the case of the axle and gearbox castings will result in oil leaking past the threads.
