My refurb of the 400 is going relatively problem free, just finishing the engine build and I have just found a most annoying problem that I can't seem to fathom out, I am hoping it is not an act of total muppetry on my part!!!
On attempting to replace the tacho drive gear into the rocker cover I dont seem to be able to get the guide sleeve far enough into its hole to permit the oil seal to be fitted correctly. I have checked the hole - No obstructions. It came out when I stripped it all down and it dawned on me...should I have fitted the drive from the inside of the rocker cover prior to refitting? !!!
I am embarrassed having to put this in the public domain!!!
Wincing...Expecting a barrage of flak!
Thanks
Rick
