well didnt have work yeasterday so ran two tanks at the show grounds, had a ball. hit a tree pretty hard but broke nothing. feels good when you go home with everything in one peice! we all know it doesn't happen all the time.
 
not sure if ive posted this vid on here before, taken and loaded by a mate Brad to does all our camera work. this is the flat track and showgrounds ive been going on about. very small and tight, the trees make it real interesting and fun.

I need someone's help BAD!

ran four tanks yeasterday, did my steering servo which is easy enough to fix but now there's a real tight spot with the belt system. I removed the engine, radio tray and fuel tank last night, took out front and rear diffs, sprayed everything with RP7 and put it back on, still a tight spot. any idea how I can trouble shoot this?
 
Now that its all back together the easiest way will be to pull one thing off at a time and test it, ie if its tight with a complete car pull the spur gear off, if still tight pull off the next gear and so on. As soon as you pull something off and its not tight thats where the problem is
 
found the problem yesterday, thanks all for responses.

there is a small pulley in plastic housing that sits under the engine infront of rear diff, one of the bearings was completley seized, i cleaned it and sprayed it and got it turning again, put the whole system back together and working like new again.

im thinking i may be better off replacing these bearings with new ones though, thier on the noisy side, what do we think?
 
noisey bearing = knackered
if when you spin a bearing you can keep clunks, or grittiness, then it's knackered
if there is play in a bearing, it's knackered.

so yeah, get em replaced. something sealed would be good, but if you have the option, go for a medium to high temerature bearing, because it will be under the engine the heat could liquify the grease, and that'll prematurely kill it. Just don't buy the bull about ABEC ratings, it doesn't apply to the type of bearing you will need for the pulley
 
cool thanks, i ordered new tensioner and diff housing bearings today from CFR, werent cheap but their definetly noisy and sound a little gritty.

might look into those rubber sealed bearings next time I replace em.

should have everything tommorow so hoping to put it back together tommorow and see if it runs on the bench, this is the first time ive had the belt system apart so want to make sure ive done it right. looks ok, can spin it by hand easily, just don't want that belt jumping off while its running! that would do some damage!
 
quick vid of the weekends action at the show grounds on flat track.

busted my steering servo early into the vid (after fourth tank on same day) so not much of that but the rovan copt and absolute flogging and had some scars to prove it!

finsihed putting the baja back together, now has 1,000wt oil in shocks, 5755, new bearings in the tensioner and custom alloy tray, cant wait to try it out.
 
cheers mate, hopefully get some more vids this weekend, im really loving that spot but its getting rutted out pretty bad.

hopefully ill also get some vid of my last run with the beetle
 
well ran four tanks in the beetle over the weekend but had a bit of carngae to show.

somehow broke 3 engine mount bolts in half and blew the base gasket. replaced the base gasket yeasterday but first time for me so lets see if ive don't it correctly. just waiting on some more mounts now.
 
im thinking of tearing down the baja in the next couple of weeks to do a full clean and rebuild, do we think its a good idea if I doco this and post up pics? do you think it would help anyone?
 
it can go either way with me mate LOL.

ive had it down to nothing to repalced the tensioner before and put it back together ok then so one would assume I would do it correctly second time around LOL
 
a write up of how to strip and rebuild would be quite usefull. The first time I took the diff of my 2wd out I ended up dismantling the entire back end, I'm sure there is a better way.....
