This kit contains the usual parts required to service E61 group heads (lever operated). There are two options for the kit, a minor and major service.

Minor Service kit - If your machine has been serviced within the past 18 months it will generally only need the following:

• 8.5mm group seal
• 8mm group seal
• 0.8mm spacer
• 0.5mm spacer
• E61 Shower screen
• 3 x valve seals
• 3 x cam seals
• Mushroom filter
• Molykote lubricant

If your machine needs a little more "TLC", then the major service kit is probably what you need.
