aux belt jumping uneven

Postby bernies » Thu Sep 06, 2012 1:37 am

My 02 90/350 Transit has Just had chain guides replaced,
now I am having one problem after another, needed new timing chain cover, new oil pump, new sump, new idler pulley, viscose fan pulley, tension pulley.
now belt is jumping and trying to slip of alternator pulley and making a noise. however this was never a problem at first, I have now been told there is play on the
power steering pulley causing the belt to run uneven and make a noise and will now I need a complete power steering pump. I suspect the crank pulley may need aligning or replacing as I have noticed slight burs on the grooves due to the mechanic using a chain grip to hold in place whilst undoing the 3 bolts :?:
can any one help or advise, many thanks

The garage has took off the crank pulley looks damaged with lots of tool marks,
Got another pulley waiting to be fitted, the garage now tells me the wrong crank cover was put on,
I was not aware they have different ones, is this the case? Or are they pulling my leg no pun intended,

I have been told by garage they will have to put a washer behind pulley to prevent the belt coming off, sounds like a botched job to me.

Right the garage had put washers on the bracket od the vicose fan pulley, now runs a treat but wait for it, the front crank O ring leaking oil, this should of been changed in the first place, not happy, have to wait another day to get my van back, has any body else had this type of experience?

Only when the timing cover has been removed by someone who is incompetent or not used to transits, which would ,make me VERY suspicious of how well the timing chain has been re set, and how well the bolts have been tightened / or overtightened (especially the cam sprockets). Everything you have posted so far rings alarm bells of abd workmanship and inexperience....

I assume the same person knackered the front cover as they are usually re usable if you know what your doing, Yes there is a gasket on the back of the cover behind the viscous fan and idler pulley bolt holes, and behind the coolent elbow bolt holes, both should have stayed on the cover, but if anew one has been fitted they are probably still on the old one instead :roll: No the covers are not different on a 2.4 engine.

crank pulley should not have been held to undo the bolts, there is a much better set of options if your used to doing it.

shimming the pulley with washers is deffo a botched job, and not recommended.

When cover was removed and replaced the following should also have been replaced, front crankshaft oil seal, water pump to block gasket (oil will leak from here if not imediately afer a few miles), the o-ring on the coolent elbow, again it will leak if not changed (and without the gasket on the inside of the cover will allow coolent to mix with your oil :shock: )

What needs to happen in my opinion and for your piece of mind and your engines 8) is to take it to wherever the timing was done and demand it be done again / re checked from scratch and ensure they do everything correcty, including putting correct gaskets back in behind the cover, and do all timing related bolts to correct torque (the guides and tensioner blade bolts snap whilst driving if overtightened :shock: )

or take it to someone who is used to doing transits. The whole job of stripping and putting back together shouldnt take more than 2-3 hours tops (if that long) :wink:

there is only one cover there all the same for the 2.4,they will have to be peplaced if not taken off with a lot of care as they are thin and normaly stuck with first class silicone,ford recommend to replace them,...crank oil seal should be replaced,and cover lined up correctly(not just bolted on),why have they used washers to lined pulley up,there is a triangle spacer/gasket directly behind the fan pulley inside the cover could be thats been left out,sounds like a bunch of bodgers to me ,giving you bulls@@t,hes had trouble undoing the crank pulley bolts and damaged it hope you didnt pay for new pulley :roll:
must of wrote this same time as andy

Yes you are both correct I had made a Big mistake by taking my van to a back street garage,
Just got back here in time, they tried telling me the new oil seal was the wrong size, only for me to note that the tubular plastic insert was part of the packaging to ber ring, when I get the van back I will take it to a ford specialist and have them correct any mistakes plus make a report, then I will re bill these jokers, had I had all the correct tools I could off done this myself, some people have all the gear but no idea, I will not be holding my breath so therefore I will
Keep this thread open for now, :?:

Believe it or not it only went in for two broken chain guides,
Everything else was ok, I am so annoyed,

has the belt been changed as it could be starting to slip after all the other problems its put up with :wink: Also regarding the seal, did they leave the plastic bit in whilst fiiting it, or did they remove that first then fit it?

yup, thats why I need to know if the plastic was left in or not...not so much on the piss but knackers the inner part of seal if not fitted correctly. :wink:

The seal was put on with cover still on, and the rubber part and outer disk were put on togeter then turned slightly into place tputting a kink in the seal thus oil leak also drove 2 miles my oil light went on then off, they told me the put fresh oil in, but it is black and very thin, so not happy, taking van back Monday to get thin,

oil will be thin, and if been driven will probably be quite black. As for seal, the outer plastic bit is attached to the inner rubber part, that is correct, but in the "hole" in the middle of the rubber part that the crank goes in there should have been a plastic cylinder about 25mm long passing through where the crank shaft goes. As you push the seal in towards the cover over the crank, the crank pushes the middle plastic tube out till it falls out completely, leaving the crank in place of it. That plastic tube is esential as the inner wing of the rubber seal slopes IN towards the engine, and wihtout the plastic tube as a guide, just pushing the crank through the rubber seal would fold the inner wing OUTWARDS towards the front, causing a leak. The action of rotating the seal to lock it in place shouldn't cause damage, as the cranckshaft is rotating constantly in this manner whilst driving.

hope that makes sense,
Andy :D
