Slave Cylinder, Clutch - Land Cruiser 3B BJ40/2, & early BJ60 - short clutch slave (w/pushrod) (Japan) - 31470-60050

Slave Cylinder, Clutch - Land Cruiser 3B BJ40/2, & early BJ60 - short clutch slave (w/pushrod)

Note: the difference between the short clutch slave cylinder (early vintages) and longer slave cylinder (later vintages) is that the short one was found on earlier 3Bs with the cast iron bell housing vs. the later longer slave one that is found on an aluminum bell housing.

This unit is for the Cast Iron Bellhousing

Important Installation Notes:

**Please advised that any failures relating to over-extension of the piston due to:

1). Missing return spring at the slave cylinder.
2). Over-extension of the piston due to a worn release arm where the pushrod contacts it (or has worn through it). Place a small amount of grease (preferably moly grease) in the pocket where the pushrod contacts the release arm.
3). Improper adjustment of the pushrod and free play at the release arm. Check the correct measurements in the Factory Service Manual.
4). Incorrect setting of the mechanism freeplay and pedal height when replacing a clutch master cylinder.

-->> Are NOT warrantied. These are installer errors.

Important Explanatory Notes:

Explanation for 1.) above: there’s a return spring that must be in place that resets the position of the clutch release arm after each pedal depression. If this spring is missing the adjustment of the slave cylinder push rod/release arm will not be correct and can lead to poor clutch performance and/or over extension of the clutch slave.

Explanation for 2.) above: it is very common for the small diameter push rod (hard steel) to create a wear hole in the release arm (softer cast steel or iron) that will wear into and even through the arm. This will need to be inspected and fill welded and 'pocketed' to support the push rod from falling out (use a drill to create a pocket after welding) before you install a new slave if it is at all worn (more than a few mm deep beyond the original pocket). If the push rod has worn through the release arm it may cause the slave cylinder piston to pop out of the cylinder bore thereby damaging the piston seal. This may also cause poor clutch performance and strange clutch release characteristics.

Pro Tips:

Most premature failures of clutch slave cylinders can be directly linked to a few common causes:

• The brake fluid used in the clutch hydraulics was not changed on a regular basis, thereby holding in water which rusts the cylinder bores from the inside and wears out the seal.
• There was contamination of the outer part of the bore from dirt and water.

To solve these common failures:

• replace the clutch and brake system fluid on at least an annual basis with good quality brake fluid from a (new) sealed container. DOT 3 fluid is fine, DOT 4 fluid is better.
• Lubricating the piston, seal, and the bore of the cylinder with a silicone brake lubricant such as Sil-Glyde can prolong the service life of the slave cylinder.
