Is there any information on stripping, rebuilding and priming standard hydraulic tappets on a twin cam 88?
I can’t find anything online about this.
I have stripped them and put them back together again, no problem.
I just wondered if I needed to fill them with oil before I rebuilt them or if it’s ok to just coat the insides with oil and leave them empty
(ie, do they fill themselves when the engine is started, or do the need to be primed in a particular way).
Any help on this would be great.
I look forward to hearing back from you.
A:There is no need to prime the lifters before installation. It is important to re assemble them with assembly lube, or clean 20/50 wt oil; as you had mentioned. When you 1st start the m/c, do not rev it. Give the lifters a chance to bleed up. If you hear a little “ticking”, pay attention to it, but do not be overly alarmed. Some lifters take longer than others to bleed up. Thanks, and good luck.
