soz the pics didnt load ill get them on as soon as i get better wifi
Hey brains trust!!!
I've recently aquired a SIIa SWB, with a 186/179 conversion (originally it had the 4cyl), to put in my SIII ex mil LWB (Grug).
I pulled the 186/179 engine out of the SWB with the adaptor plate, gave it a clean and when im ready give it a bit of a service. From all the information I could find online, the 186/179 should have been able to go into the SIII pretty easily if i took the bell housing off the SIIa to accompany it. Is the information I have correct???
The bell housing on the SIIa when we tried to get it all off, the Primary pinion shaft had been welded at the bolt, completely contradicting the information I had found online.
When I took the blown 6cyl out of the SIII, the difference between the pressure plates was significant, so I wasnt sure if that conversion was even possible. Id prefer it if i could keep the SIII gear box, however, I have taken the gear box out of the SIIa to clean up just in case I had todo the entire conversion. Its been an epic couple of days
I've included some pics for you to have look at, would love some advice
Cheers

There is usually an adapter plate that is bolted to the back of the holden motor. This is different if it was originally a four cylinder or six cylinder landrover so you may have some problems depending on that. S2a and S3 bellhousings are different but the bolt pattern is the same (again depending if it was 4 or 6 cylinder). The clutch is different for S2 and S3 and the method of actuating it is different.
Welded bolts are not usually standard .
Hope that helps a bit.
Cheers,

Need to see some pics of what your talking about regarding being welded up. (i think you mean the large "castle" type nut at the rear of the gearbox???)
To transfer the conversion over from an original four cylinder Land Rover to a six cylinder you will need different engine mounts (longer) and an identical adapter plate, but with a different bolt pattern on the gearbox side of it. You will need to use the radiator from the shorty or get the outlets changed on the one in the lLWB. It is possible to modify the existing adapter plate you have by drilling and tapping new holes. If the SWB you have acquired is a late 2A you might be lucky as i believe some bell housings will interchange, but not all. Maybe if you can get the numbers from the two gearboxes you have someone on here will know for sure if the bell housing can be changed. A chassis number from the SWB might help too.
Here are some pics of engine mounts to suit a Holden conversion in a four cylinder and six cylinder series Land Rover. The long ones are for a six cylinder Land Rover engine conversion and most are fabricated from flat pieces of steel like the four cylinder ones. These cast ones are a less common type.
I have also put up pics of two adapter plates so you can see the difference regarding the hole patterns. The one attached to the engine is for a four cylinder gearbox and has the top hole at 12 o'clock, whereas the other one is for a six cylinder and has the top holes at 11 and 1 o'clock.
Hope this helps,
Cheers, Mick.
