Such a useful series of videos: it’s really helpful to see the processes being carried out in full. Instead of just saying ‘counterbore the threaded holes’ you actually show us how to do it, with measurements and tips. Probably a little tedious for you who have done it a thousand times before, but for those of us who have never had a go - gold dust! Thanks, gents.

This is a very important, and essential procedure before starting assembly of any engine.

Why do you counterbore the block to gearbox threads before redrilling and tapping to 5/16 unf? I would have expected it to have been easier to accurately drill for re threading before counterboring? Thanks for super knowhow video.
@bryantear1953 Жыл бұрын
Easier to drill for the 5/16 from a hole that is counterbored as the drill will follow the counterbore. If it's threaded already it will try to follow the thread which will then produce a hole which is untrue or not concentric.

Hi there. Nice professional work. Do you have already worked on engines, and if so how much can it cost? Thanks.
@Slack3rDav3 Жыл бұрын
for clarification: do you drill out and then tap each hole, switching bits for every hole, or do you drill all holes out then tap all holes out? It looked like you drilled and tapped each hole, so as to keep the tap true to the drill hole.

Im a bit confused. You say you use a 9/32 on the 5/16 unf holes in the block? When i have tried this only the tips of the threads are removed, should it be a little bigger? Also, related, should the main bearing dowel holes be countersunk? And what size should be used? (using a drillpress)

Amazing!! Love the idea of the copper gasket! Would you use sealant on them?
@MEDEngineeringTechVideos Жыл бұрын
Just a bit of grease usually. Some use a light smear of RTV sealer.

If you have a thin-flange block, is it still worth going to the larger fixings for the gearbox? Cheers Will

Why not go metric and do the gearbox threads m8 or is it just to be consistent and keep them UNF? Great vids, takes me back years to when you were on avenue rd!
@MEDEngineeringTechVideos Жыл бұрын
Best to keep it all imperial, to save someone cross threading everything in future. Glad you like the videos!

Great..but why not go to metric when you are retapping?
