    Posted: 18 Jan 2018 at 16:57
My V50 engine hangs on the front of a Pembleton Grasshopper (3 wheeled taildragger based on 2cv running gear.) I hope no one will hold that against me!
I need to replace the front oil seal and I can remove the alternator and timing ok. I just need to know about the seal itself.
1) Any good tips for removing the old one?
2) The workshop manual talks about two special tools (19 92 74 & 19 92 72) for locating the new seal and driving it into place. Is there a good way of inserting it without these tools?

I may be seeing problems before I get to them, but if someone can advise me before I start I shouldn't be off the road too long. Many thanks.

Hi and welcome
Is it the crankshaft or camshaft seal you are wanting to replace?

Does your V50 have a Bosch alternator? if so the oil seal is behind the alternator take the cover off , remove stator Use the proper tool to remove the rotor the seal is behind that I used a flat blade to pop it out get one of the newer ones Gutsibits sell them I use a large socket to gently tap it home, top tip use a fine smear of silicon on the outer edge ..... not sure about procedure on other alternators ....

Unless modified it will be the Bosch.
 
The only other point is does it have points above the alternator (Mk 3) or electronic pickups behind the alternator (Mk 2)?
 
If the latter, it's a bit more difficult as the pickups have to be removed. They must then be reset very carefully to get the correct timing and air gap, both must be identical.

Thank you all for your help, I think you have covered my problem. If I find that I don't have a socket of the right size which is deep enough I'm sure that I will be able to either scrounge or improvise.
Thanks again,
Martin

If it is a mk II and you can avoid removing the ign pickups then do so. The timing on these is a real PITA to set up otherwise.
