Tranny Bolts

[gnosez]

Looking for the size, thread and length of the bolts used to connect the tranny to the engine.

Thanks

Pretty sure that EuroDat knows.  I think that he made a list.  You might find it with a search.  Or a PM.

70mm m10 x 1.5 rings a bell but double check. Also depends on what transmission you have. 5spds require the longer bolts (70), where as 4 sp you have shorter ones.

I think that the later 4 speed, and 5 speed bolts might be the same.  carpartsmanual shows the same part numbers, just different quantities.  Weird.  I just used my 4 speed bolts on all of my 5 speeds.  Seemed to have plenty of thread engagement.  Looks like the very early 4 speed had one bolt different from the later 4 and 5 speeds.

 

Also, I think that the bolts are still available from the dealer.  $1.12 each at courtesy.  A good parts guy could find them on the microfiche.

 

Of course, if you're not looking for the parts, just the specs. this may not help.

All 4 bolts are M10x1.5 pitch.

The lengths are 3x 60mm and 1x 65mm.

Part numbers

M10x60mm P/N: 08131-0601A (was 08131-06010)

M10x65mm P/N: 08131-0651A (was 08131-06510)

M10x70mm P/N: 08131-0701A (was 08131-07010)

Spring washer P/N: 08915-2401A

You can use 70mm. They will fit with about 6 to 7mm spare. The hole depth is about 75mm.

Don't know about anyone else, but I use standard American thread bolts for my engine stand. They go in nice and easy. But I do use the metric for assembly
