bleedin tappets

Post by **nelly** » 04 Jan 2006, 19:24

two of my hydraulic tappets need to be bled on my 2ltr cu, only problem is, with the reassembled tappet emmersed in a container of oil ( as instructed by the book) i am finding it near impossible to push the plunger down to fit the circlip! any one got any tips or other methods that may be of help!

It's all rather tricky isn't it...
I put a G-clamp in the vice and used its screw-down pressure to compress plunger and insert the circlip (I didn't have an old bit of pushrod like the books suggest so I filed a brass bolt smooth and dome-shaped) - all while it is in a plastic pot of oil.
Have you looked at these sites:

Particularly the last one... (nice pics!)

Please advice procedure for setting hydraulic tappets from scratch.I took off the rocker gear to replace tube seals i discovered there are no sprung wires to hold down tube seals both cylinders.The haynes manual explains turn to no 1 cylinder to mark on distributer line up.Turn tappet screw till just touching valve stem then screw twice then lock with nut .Go on to no 2 /3/4.Does this mean screw down clockwise twice 360%.

Yes that is 2 turns after contact - there is a variety of opinion on this issue - some say only one turn. If you do a search for hydraulic lifters (the US term) you should get some info on this. I've got some page links saved at home so could point you at them later.

Here's one to be going on with:
