Timing Chain, Oil Pump Chain, Tensioners, and Guide Rails for the S55 engine in F87 M2, F80 M3, and F82/F83 M4.
Planning S55 engine work that involves the timing chain or VANOS? This will be a very valuable add-on to existing work done on the S55 such as rod bearings or a crank hub upgrade.
This kit is meant as an add-on to already-planned engine work. Some pieces have been left out in anticipation of them included in other kits (and there's no need for redundant parts).
This kit includes -
1 x 11318648732, OEM timing chain
1 x 11317585020, OEM timing chain tensioner and guide rail
1 x 11317592850, OEM timing chain slide rail
1 x 11317584723, OEM timing chain tensioner
1 x 11417584079, Genuine BMW oil pump chain
1 x 11417618941, Genuine BMW oil pump chain tensioner rail
1 x 11418091535, Genuine BMW oil pump chain sprocket (small)
3 x 07119907242, Genuine BMW oil pump chain guide rail screw
1 x 11417618943, Genuine BMW oil pump chain tensioner
1 x 11417519870, Genuine BMW oil pump sprocket (large, main)
1 x 11417520144, Genuine BMW oil pump sprocket screw
At minimum, you must have -
1 x 11317523891, sprocket plastic retainer
1 x 11117853941, oil pump & oil pan hardware set
1 x 11137600482, oil pan (or a complete lower-end gasket set)
1 x 11117530262, front cover lid (large)
1 x 11117615131, front cover lid (small)
We don't want you to buy things twice. You must have the above items either through another kit or buy purchasing them separately. We have included them in our other kits for rod bearings or a crank hub upgrade so we did not include them in this package. We also strongly recommend upper or lower complete gasket sets. Note that BMW sometimes duplicates hardware or gaskets and there is no returns on Genuine BMW kits if this is the case. If there's any confusion, please contact us.
Again - you MUST HAVE additional parts already on hand or in a different kit. This timing chain/oil pump chain kit is meant as an add-on to existing kits that include more items.
This is a kit of OEM and Genuine S55 timing chain and oil pump overhaul parts. OEM parts are from the original supplier to BMW for many other engine components. As an OEM it meets all of BMW's original design, fitment, and performance requirements and is TUV approved. OEM parts are the best alternative to more expensive Original BMW parts because they are virtually identical without the inflated price tag. This part has a two year warranty.
