Install timing set

Part 1. Preparation and safety

Objective

• Install the timing set.

Personal safety
Whenever you perform a task in the workshop you must use personal protective clothing and equipment that is appropriate for the task and which conforms to your local safety regulations and policies. Among other items, this may include:

• Work clothing - such as coveralls and steel-capped footwear
• Eye protection - such as safety glasses and face masks
• Ear protection - such as earmuffs and earplugs
• Hand protection - such as rubber gloves and barrier cream
• Respiratory equipment - such as face masks and valved respirators

If you are not certain what is appropriate or required, ask your supervisor.
Safety check

• Make sure that you understand and observe all legislative and personal safety procedures when carrying out the following tasks. If you are unsure of what these are, ask your supervisor.

Points to note

• If you can't see the timing marks very well, paint them to make them more visible.

Part 2: Step-by-step instruction

1. Install timing gears
   Engines that have pressed-on lower gears will already have that gear fitted on the crank. If you have a thrust plate for your camshaft, double check that it's in place, torqued and thread-locked before the timing set covers it up.
   For non-slip-on timing sets, put the larger upper gear on the cam and line up the timing marks. Pull the gear off the cam and put some assembly lubrication on the surface that will ride against the block. Soak the chain in some oil and then place the whole assembly on the block with the marks lined up. If you have the slip on style timing set, put both gears in the chain, line up the marks and then slide the timing set on.
2. Lock in timing gear bolts
   Some cam kits came with a cam bolt plate that must be put on just before the cam bolts. When you have one or two bolts in, double check that your alignment is correct. Iif you can't see the timing marks very well, paint them to make them more visible. Now torque the gear to the cam.
   If you don't have a cam bolt lock plate, put some thread locking liquid on the bolts before you put them in. If you do have a lock plate, bend back one tab per bolt with a chisel so the bolts will not be able to work themselves loose.
