Changing RB30 Nissan water pump

Thanks for your reply Phil
Do you think this is something I should attempt without the manual ??

Thanks
Steve

I'd always follow a manual. Getting it wrong can be costly. Hopefully someone here might have a manual and post the info.

"Installation is the reverse of the removal procedure"

Once it took me 40min to take a Kingawood window out ,and about a week to get it back in !

This is my favourite call at work , espescially if someone has everything well apart !

LOL

Removing timing belt.

Remove the drive belts from power steering pump, the alternator and if applicable the a/c compressor.
Remove the crankshaft pulley retaining bolt.(It may be necessary to to wrap and old drive belt around the crankshaft pulley and hold the belt with a lever to prevent the pulley turning.
Install a harmonic balancer puller to the crankshaft pulley and withdraw the pulley from the engine.
Disconnect the high tension leads from the upper timing belt cover.
Disconnect the charcoal canister and distributor hoses from the pipes at the front of the timing cover and place the hoses to one side clear of the work area.
Remove the retaining bolts from the upper timing cover, lift the high tension leads clear of the cover and manouvre the cover from the engine.
Remove the timing belt guide plate from the crankshaft gear and ensure that the timing mark on the gear aligns with the timing mark on the oil pump housing.
If the timing belt is to be re used it will be necessary to mark the belt with an arrow to indicate the direction of rotation of the belt and also the position of the camshaft and crankshaft gear timing marks.
Loosen the timing belt tensioner locknut, rotate the tensioner clockwise using an allen key and tighten the locknut to hold the tensioner.
Slide the timing belt from the crankshaft and camshaft gears.

More to come need a break lol.

Your doing well so far. This is excellent !!!

To install

1) Ensure that the No 1 cylinder is on TDC with the crankshaft gear mark aligned with the mark on the oil pump housing.
2) Ensure that the dowel pin on the camshaft is in the upper most position.
3) Install the tensioner and the spring to the front of the cylinder block ensuring that the spring end engages the stud in such a manner that the tensioner will tension the belt.
4) Install the flat washer and then the wave washerwith the concave part of the washertowards the tensioner.Position the tensioner pulley away from the timing belt using an allen key and temporarily tighten the locknut.
5) If a new belt is being used it should be markedIf not put a mark on the belt above one groove and count back 53 grooves from this position. Put another mark above the 53rd groove.
6) Slide the timing belt onto the camshaft and crankshaft gears ensuring that the marks on the belt are aligned with the timing marks on the camshaft and crankshaft gears and that the directional arrow is pointing as marked at removal.
7) Loosen the tensioner locknut and allow the tensioner to tension the timing belt.
(note. The rocker arm retaining bolts must be loosened off as previously described otherwise the timing belt tension will be incorrect.)
8) Using an allen key rock the tensioner in both directions 2 or 3 times to ensure correct belt tension)
9) While holding the tensioner in the position with the allen key, tighten the tensioner locknut to the specified torque. ( Do not apply any more than spring tension to the timing belt or noisy operation and excessive wear will result.)
10) With the dowel pin on the camshaft gear uppermost, tighten the rocker shaft bolts for cylinders number 4,5 and 6 to specified torque.
11) Rotate the engine in a clockwise direction,using a spanner on the crankshaft pulley nut until the dowel pin on the camshaft gear is pointing downwards. With the dowell pin in this position tighten the rocker shaft bolts for cylinders 1 2 and 3 to specified torque.
12)As the final check rotate the engine clockwise again until the dowel pin is uppermost and check that all rocker shaft bolts are tightened to specific torque.
13 ) Install the timing belt guide plate to the crankshaft pulley with the concave surface facing outwards.
14) Install upper and lower timing covers ensuring all seals are correctly attatched. Thighten the retaining bolts to specified torque.
15)Install the rocker cover.

Then back to water pump instructions.

3 cheers for The Brewman !!!
Mate that was a hell of an effort, and an extrordinary amount of work to help out a complete stranger.
I'm sure that has earnt you a whole new level of respect ( not that you didn't have any before lol.) on this forum, well done.

Brew69, you're a legend.
Wow, what an effort!
I'm impressed!!!!
Cheers

And be sure the fan clutch assembly is in good order since any vibration on the fan unit is going to shorten the life of the new pump bearings. good luck

The TB42 is much simpler.
If i was doing the above i would be doing the lot like you suggest mate.

A socket and long bar resting firmly on the chassis and a short quick flick of the starter motor (spark coil isolated) did the job. ???????????

has your mate ever seen this done only to have the crank snap in half???????

not a good idea..

any half decent mechanic will have a 3/4 inch rattle gun for that job

donks

HI Steve......i agree with Brew .if you going to do water pump.change timing gear at the same time ...did all mine two months ago..even just for peace of mind regarding timing belt.you know its done and wont have to worry about it for years
...Cheers BUNDY
