Frequently Asked Questions
Q: What is the torque specification for the cylinder head cover?
A: Torque specifications for the cylinder head cover should generally range between 20N-m and 25 N-m (2.0 – 2.5 kg-m, 14 – 18 ftlb.)
Q: What signs indicate wear of the valve guides?
A: Take into consideration the I.D. of the valve guide and the O.D. of the valve stem. If the stem-to-guide clearance goes above the service limits for the guides being currently used (IN: 0.11 mm, EX: 0.12 mm), then new guides might be necessary.
Q: In the case the compression pressure turns out to be low, how can we resolve this?
A: On certain occasions the compression might be low and this might be caused due to burned valves, damaged head gasket or leaking cylinder head. For the precise solution the cause can be traced via a compression test.
Q: In what ways is the hydraulic tappet being adjusted/ fitted?
A: Shims need to be applied to hydraulic tappets on occasions when the head cover cylinder or the camshaft gets changed as parts that get replaced do not allow for hydraulic tappets to adjust themselves. Measurements and shims have to be adjusted according to the shim chart handy in the manual.
Q: In the event a cylinder head is warped, what steps can we take to fix it?
A: A warped cylinder head which exceeds the service limit of 0.10 mm (0.004 in) cannot be utilized, such cylinder heads can either be replaced or machined to achieve a flat surface.
