Twin impellor lift pump seal failure

tilt engine and remove all bolts that hold gearbox to leg , put box in vice and remove impellor house and remove impellor , check all holes and seals below housing for damage etc , if impellor has broken up then check water down pipe is clear , you can run engine with box off and put hose to down pipe and turn water on and run engine for 20min and see if engine cools b4 you fit box so you know no blockages etc ! as you fit impellor rotate clockwise as you push down on housing , bolt up and fit box and as you do turn flywheel to engauge driveshaft ! Bobs your uncle ....

if you mean a large flat sided 'O' ring then this is to help keep water in the impellor housing !? some housings have gaskets between the base plate and housing , check the impellor in the housing and see if it stands proud as then you need the gasket ! compare with the old one as it mite have been forgotten !! check the seal and tube for the water pipe also ok!

Hi mate this will be the oil & water seals the leak from weep hole is basically a warning light to tell you it needs replacing asap, you need to remove impellor, carefull not to lose the spacer washer behind it...then remove the water seal clean the surface it came from and replace with new seal. Now to do this 100% I would always replace the impeller shaft as the shaft wearing is usually what caused the seal to fail and I would also replace the oil seal which is the other side of case that you just changed the water seal (oil seal sits behind the small bearing) I would also consider replacing this bearing but maybe not critical? all up the impellor shaft the 2 seals and bearing last time I bought cost about $160... no special tools required just quite a bit of time required as you should really remove the outer engine case to access the impellor to undo it and to get to the oil seal and bearing, how ever I know guys do just open the water pump cover then rattle gun off the impellor only replace the water seal then install the impellor and cover back on then ride away! this will work and will fix the leak but is definitely the incorrect way to repair this and will be temporary fix but thought you may like to know this alternative as is very handy way to do it if your on a race meeting and just need to get through the last race or two.

Hi, this all depends on how mechanicaly minded you are, i fairly sure that the old water pumps were servicable by removing the cover from the engine, remove pump cover removing the impellor and then gently tap out the seal, replace in the same manor, replacing ness gaskets, the oil and filter will also be removed and replaced and a new gasket will also be ness for the main case, time will be required for cleaning the cover and main cases

there is really only two ways for oil to enter the oil (1) is the oil and water seals fitted on the water pump impellor or (2) the other is head gasket leak
the most common on MX bikes is the oil and water seal at the impellor (water pump)
if your not to mechanical minded then both of these issues you would be best to take to dealer to rectify as they bit tricky to do with out experience.
if you are mechanical minded then either problem is fairly cheap to fix about $25 for the oil water seals or about $70 for the head gasket
let me know if you want me to elaborate on either issue
good luck regards Jamie

yes steve- this is the water pump by-pass hole. There is a secondary backup al behind it to stop the water entring the gearbox. Replace the waterpump seal. Most suzukis' use a mechanical seal. they are prity easy to change- although usually requires removal of the clutch cover. I always replace the mechanical seal, back up seal & the bearing all at once.If it is a standard seal type- be sure to ckeck the shaft of the impellor for groves worn in it where the seal contacts the shaft - in mechanical type seals this does not apply.
Hope this helps regards

It Depends on which engine you have, this is how it goes for both. I use a little RTV with a new ring as well.

THERMOSTAT REPLACEMENT (4.2L ENGINE)
Removal Procedure
1. Remove the necessary coolant from the radiator.
2. Remove the generator.
3. Loosen the outlet hose clamp at the thermostat housing. Remove the outlet hose from the thermostat housing.
4. Remove the thermostat housing bolts.
5. Remove the thermostat housing from the engine block.
6. Clean all of the surfaces of the thermostat housing.
7. Clean the sealing surface of the engine block.
Installation Procedure
1. Install the thermostat housing to the engine block.
2. Install the thermostat housing bolts.
Tighten: Tighten the bolts to 10 N.m (89 lb in).
3. Lubricate the inner diameter of the radiator hose with engine coolant.
4. Install the outlet hose to the thermostat housing. Secure the hose with the clamp.
5. Install the generator.
6. Fill the cooling system with specified coolant and concentration. Follow the correct cooling systen bleed procedure for your engine.
7. Inspect all sealing surfaces for leaks after starting the engine.
THERMOSTAT REPLACEMENT (5.3L ENGINE)
1. Drain Radiator and remove the radiator outlet hose.
2. Remove the water pump inlet bolts.
3. Remove the water pump inlet and thermostat from the water pump.
Installation Procedure
IMPORTANT: The thermostat is not serviceable separately. The water pump inlet and thermostat must be replaced as an assembly.
1. Install the thermostat and thermostat housing to the water pump.
2. Install the thermostat housing bolts.15 N.m
3. Install the radiator outlet hose.
4. Fill the cooling system with specified coolant and concentration. Follow the correct cooling systen bleed procedure for your engine.
5. Inspect all sealing surfaces for leaks after starting the engine.

Iv'e changed heaps of these.Follow these steps taking carefull note of where & how everything goes to make it easy to put back together. make sketches if necessary.

• Drain the coolant & engine oil
• Remove the hoses that go to the water pump
• remove the waterpump cover
• remove the impellor
• remove the kickstarter
• remove the clutch cover & locating dowel pins if they are still in the clutch cover(if they didn't stay in the crank case)
• the water pump seal is a (ceramic) two piece unit
• remove the ceramic disc & rubber holder from the back of the impellor
• remove the impellor drive shaft from the clutch cover
• behind the impellor drive shaft there is a small bearing. To remove this I heat around the alloy of the bearing with a heat gun (or butaine gas torch,if using an oxy torch use a small tip & take care to heat evenly & not melt anything/or heat in an oven to 80 to 100 degrees max)Use welding gloves to handle the hot clutch cover)
• turn the cover over & whack it down on a flat piece of wood(9 times out of 10 this is enough to shock out the bearing
• remove the back-up seal from behind the bearing you just removed noteing the direction it was facing(for reassembly)
• now using a suitable drift,knock out the other half of the mechanical seal
• scrape all the gaskets & clean the parts
• check the impellor drive shaft to make sure the shaft is smooth & dosn't have any groves worn in it.If it does you'll have to replace it
• I always fit a new impellor bearing & back-up seal & new gaskets when doing this job
• reassembly is reverse of removal noting the following
• to install the bearing & seals use a socket that matches the OUTSIDE diamiter of them so you don't damage them.To install the rubber cup & ceramic washer into the impellor DON'T use a drift just push them in by hand
• apply some grease to the impellor shaft before installing it
• Apply some soap to the ceramic disc before re-fitting it
• to install the clutch cover, if it won't go on at the front near the impellor, turn the impellor shaft to engage the gear
• refit kickstarter,waterpump cover,hoses
• re-fill radiator with fresh coolant
• re-fill gearbox with fresh gearbox oil

That just about covers it all
Hope this helps you

That means that there is a leak that passed throught the waterproof system, and the water protection system had reacted putting the machine on error mode, as the water can damage electric parts, and cause serious hazard.

Sometimes you can reset the error by unplugging power cord, however you should call immediately a technician, as using the appliance when there is a problem with the waterproof system, you can be seriously injured by electric shock.
