What about putting a piece of paper behind Then putting the wheel on Then see where or if it marks the paper
Or Engineers Blue, wipe some on the drum face and it should show on the inner face of the wheel around the bolt holes.
Tried a different wheel and took the drum bolts out. Heritage are sending me some 3 and 5 mm spacers to try FOC which is fair enough
Your going to need to fit longer studs if using spacers But spacers are used to stop the tyre or wheel hitting other obstructions when the wheel has a different offset or is larger than stock. If the alloys won’t sit properly on the drum after removing the two drum retaining bolts then there’s most likely a problem with the diameter of the hole in the alloy being too small.
Personally it should be fairly simple to see where the problem is . Either with a straight edge or a caliper ! I wouldn’t run spacers but depending on the off set of the wheel you may have to .
This could all just be a layer of rust making the diameter of the hub centre just fractionally too large. Try wire brushing the area that contacts the wheel and measure with vernier calipers or a digital caliper...
I also think its the drum retaining hex bolts preventing the wheel seating. Countersink the drum retaining bolt holes and use some countersunk allen bolts or phillips screws instead of the hex bolts. The drum balancing weights are further out than the mating face I think.
ditto. i can see in the first pic the drum retaining bolts impacted the back of the wheel pad and unfortunately damaged it, but with those removed it should sit flush. if it doesn't then you should be pretty simple to put a flat edge/ruler across the face of the drum to check nothing is protruding (e.g. that weight). If its flat then it can really only be the centre being too big for the wheel (could be additional girth added by corrosion althouth tbh it doesn't look too bad). Wire brush/ copperslip the centre bore and check again or measure with a caliper.
Drum bolts had already taken out and with a 3mm spacer wheels are now sitting ok on back. Think centre hole was slightly too small and wheel was not going over the last mm or so of the middle bit of the hub where it flares out. Not too keen on spacers myself but it’s only 3 mm and I will get the rear studs swapped next week. It’s now got 15 “ premium van tyres on it which I reckon balances out the spacers anyway… Thanks
It would be interesting to see if those wheels fit okay on someone else’s bus or if they have similar problems. If so then the wheels surely are not fit for purpose & by using spacers on the advice of Heritage confirms this.
Annoying lumps of aluminium that dont quite fit over things for instance, although the studs get in the way...
