OEM 2001 Toyota Tacoma Timing Chain

2001 Toyota Tacoma Parts Questions & Experts Answers

• Q: How to remove and install the timing chain on 2001 Toyota Tacoma?

  A: The first step to remove the timing chain requires removal of engine under cover and draining engine oil. The 4WD procedure requires users to disassemble the front differential drive shafts before removing the generator drive belt together with fan components containing fluid coupling and water pump pulley. After disconnecting the A/C compressor via 4 bolts you can suspend it before you detach the 4 bolts of the A/C compressor bracket. The procedure begins with generator disconnecting and nut and wire clip detachment while uninstalling the generator along with its bracket and adjusting bar. The crankshaft position sensor removal requires the removal of its two bolts along with the O-ring. During 2WD removal operation you will need to detach 8 stiffener plates using bolts. Obtain SST 09032-00100 tool to cut sealer before removing the oil pan by detaching its 16 bolts and 2 nuts. Begin the procedure by removing the oil strainer and crankshaft pulley and timing chain cover. To remove the pulley bolt of the No.2 and No.3 crankshaft pulleys (with A/C) use SST 09213-54015, 09330-00021. Additionally, remove the 2 water bypass pipe nuts, 2 timing chain cover bolts, 9 bolts and 2 nuts before loosening the chain cover with a plastic faced hammer. You can remove the No.1 timing chain along with its camshaft timing sprocket followed by the crankshaft timing sprocket through the use of SST 09950-40011 if required. The servicing professional must remove the No.1 timing chain tensioner slipper and No.1 vibration damper while also removing the following components: 2RZ-FE requires removal of 2 bolts as well as the No.1 damper and 3RZ-FE requires removal of a bolt, nut and No.1 damper. When working on 2RZ-FE vehicles it is necessary to take off both the crankshaft position sensor rotor and timing chain oil jet. Workers must first insert a pin into the No.2 chain tensioner before removing the bolt and No.2 damper followed by the 2 bolts of No.3 damper after which they must remove the nut and No.2 chain tensioner. The sequence to remove all components includes first removing the bolt from the balance shaft drive gear followed by the gear together with the shaft and finally the No.2 timing chain and No.2 crankshaft timing sprocket. Two bolts must be removed from the No.4 vibration damper forcing its removal. Measurement of fully stretched 16 links should check for chain elongation limits and sprocket diameter requires vernier calipers during inspection of timing chains and sprockets. Verify that the chain tensioner slipper along with vibration dampers display a wear amount below 1.0 mm (0.039 inch). Checks on the oil jet of 2RZ-FE model should focus on both clogging and damages. Test whether No.1 chain tensioner and No.2 chain tensioner have fluid movements during plunger operations and lock properly. The installation procedure requires the No.1 cylinder to be at TDC while balance shafts stay at the bottom position. The installation process requires No.4 vibration damper support with two bolts, while for 3RZ-FE users need to install both No.2 timing chain and No.2 crankshaft timing sprocket alongside balance shaft drive gear, and shaft and ensure proper timing mark orientation. After installing the No.2 chain tensioner nut, proceed with adding the No.3 damper using two bolts while attaching the No.2 damper with one bolt by removing the pin from the No.2 chain tensioner. The installation process for 2RZ-FE requires the oil jet with new gasket and bolt. You should install the crankshaft position sensor rotor with its front-facing mark pointing toward the front. Place No.1 timing chain tensioner slipper and No.1 vibration damper component adjacent to each other for optimal motion of the slipper. Assemble the crankshaft timing sprocket by having the timing mark overlap with No.1 timing chain. The procedure begins with installing the timing chain cover that features three gaskets and continues with nine bolts and two nuts while respecting torque requirements. Torque the crankshaft pulley bolt using SST 09213-54015, 09330-00021 when the set key is properly aligned. The installation of the oil strainer requires a new gasket which must be torqued according to specifications followed by oil pan installation after cleaning old packing material while using new seal packing (Part No. 08826-00080 or equivalent). The installation order includes mounting the flywheel housing with its cover and dust seal while 2WD vehicle operators should fit stiffener plates before final assembly. The crankshaft position sensor installation requires installation with a new O-ring before proceeding with the generator and adjusting bar and bracket where torque requirements must be followed. After placing the A/C compressor together with its bracket users must install the cylinder head assembly followed by water pump pulley installation and fans using fluid coupling before adding the generator drive belt. The front differential and drive shafts assembly installation requires engine oil filling before starting the engine to search for leakages along with engine under cover installation followed by testing under road conditions for detection of abnormal noise and shock slippage and proper shift points and smooth operation before final engine oil and coolant level checks.
